1. How to properly and in what proportion to dilute gasoline with oil? I couldn't find the original oil from Prorab, I bought Hungsvarna HP oil. The instructions for the trimmer are written from third-party oils, you can use oils of SAE MIF \\ 4, API TC-TB. If a different brand of oil is used, the proportion of the fuel mixture does not change. The standard mixing ratio is 1:25.
But in a specialized store, the "specialist" who sold the Hungsvarna HP oil to me strongly advised to dilute it at 1:50 (as it is written in the oil). Actually the question: if the instructions say to dilute the oil by 1:25, and it is recommended to dilute 1:50 in oil, then in what proportion should it be diluted? And 1:25 is how much? 40 ml? Will I screw up the engine if I scout it at 1:50?
2. How to properly run in the engine? In the instructions, apart from starting and shutting down, nothing is written. Maybe you don't need a run-in? I read that there are trimmers that can be used immediately after purchase.
3. Does the gearbox need to be lubricated before operation or is there already factory lubricant?
Hope for your help, thanks!
1) Gasoline is diluted with oil ALWAYS in the same proportion as indicated on the can with this oil! With two-stroke products (petrol trimmers, chainsaws, etc.) you can use any oil for two-stroke engines, except for two-stroke boat engines. It is advisable to use oil from normal stores, where the probability of buying counterfeit oil is minimal. It is better to take Husqvarna or Stihl oil. Stihl oil should be sealed. Beware of counterfeits. There is a risk of spoiling the piston immediately.
2) Running in two-stroke products is not performed! REMEMBER THIS PLEASE!
All two-stroke products are high-speed and love full throttle operation!
No half gases are allowed! This leads to incomplete exhaust and coking of the piston wall with oil deposits. As a result - piston seizure. So full throttle and every 25-30 seconds, reset the throttle for 1-2 seconds to allow the product to rest and return to normal temperature conditions.
3) The gearbox in straight-shaft brushcutters must be filled with new grease every 20 hours. The oil comes out of there naturally during operation. This is done so that dirt, dust, etc. come out along with the lubricant. So if you do not want to get to replace the gearbox, fill it with special gear lubricant every 20 hours. It is not difficult and the whole operation takes no more than 3 minutes. Lubricated tubes are sold in every garden equipment store and cost from 100 to 300 rubles. 1 tube will last for 3 years.

The concept of running in a tool is reduced to working with a partial load during the development of the first two or three tanks of fuel. For example, when mowing light, low grass or cutting dry, coarse wood. In no case should you run in the tool at idle speed by burning out several tanks of fuel. As a result of such running-in, carbon deposits form on the cylinder windows, on the piston and in the muffler, which negatively affects the engine life.

What should be the proportion of oil and gasoline for the outboard motor?
It is no secret that many water engines make their own mixture of gasoline and engine oil. For this, it is important to know some of the nuances of mixing a composition of fuel and oil. Many boat owners with outboard (PLM) are interested in how to properly dilute such a mixture, in what ratio the components should be, which gasoline to choose and even how much to dilute such a mixture in time.
Gasoline and oil for boat motors
The proportion of oil and gasoline for often becomes an individual value for certain boat units. And, nevertheless, there are some general data regarding gasoline outboard motors.
How to choose gasoline for an outboard motor?
There are some nuances in the choice of gasoline and general recommendations for diluting gasoline with oil. It is best to follow them, whatever type of outboard motor and boat you have:
- remembering the obvious things that, nevertheless, they forget, most often a certain type of gasoline for an outboard motor is indicated in the passport itself for your unit. You just have to carefully study the instructions for the outboard motor. There are usually spelled out in black and white the types of gasoline that are suitable for the boat. If you purchase the right fuel, then various engine parts work very well, and the engine will not fail and will last a very long time;
- but boaters often argue about which gasoline is best for which boat. This is due to the fact that Russian refineries produce only gasoline under the marker 92. The same fuel, which is considered the 95th fuel at filling stations, is in fact the same 92nd gasoline, which has an increased octave number. It should be noted that its octave number is sufficiently increased due to the fact that there is an iron-containing anti-knock additives, methyl tert bufyl alcohol and propane butane;
- at the moment when gasoline burns, in which there is an addition of methyl-tert-butyl alcohol, ether and benzene, carbon deposits form on the so-called pistons. This can often lead to breakage or partial seizure. Methyl alcohol is hydroscapic, so it absorbs moisture from the air. As a result, in your gas tank you find a replacement 95th gasoline, which will be divided into the original 92nd gasoline and water, which will settle to the bottom;
- We can conclude that propane-butane will not, in principle, bring much damage to your parts, since it evaporates quickly enough. And after that, the 95th gasoline again becomes the original 92nd fuel. The overpayment for 1 liter will be about 30 percent. It can be concluded that if there is no imported fuel at the filling station, it is best to fill in Russian 92nd gasoline.
Principles of Diluting Gasoline for Outboard Motor
Today, the most common are electric and petrol boat motors. From the names it is clear that the electric motor will receive its power by recharging from the network. Whereas a gasoline engine needs a special mixture of gasoline and oil, with which it will function:
- it turns out that two-stroke outboard motors require careful preparation of a fuel mixture of gasoline and oil. You can fix some common numbers that are often used so as not to forget anything. It turns out that to break in your boat, you will need to use 1 liter of oil per 25 liters of your gasoline. This figure is suitable for both a regular boat and a PVC boat;
- when the boat travels long distances and is engaged in transporting heavy loads, we can talk about a ratio of 1 to 50. That is, you need to use 1 liter of oil for 50 liters of your fuel. If you plan to move with a short-term operation of your outboard motor at full speed, then you should dilute your mixture in a ratio of 1 to 75;
Mixing table for gasoline with oil for outboard motors
- speaking about the operation in a light mode of the so-called trolling (these are quite calm water movements), you can even use a ratio of 1: 100. That is, using 1 liter of oil, you can use up to 100 liters of fuel. Although experienced boatmen and experts say that it is better not to save much on oil, it will be harmful to yourself. Indeed, on the water there are also all kinds of water obstacles and so on, which can damage the parts of the outboard motor;
- however, it is worth considering the fact that when the oil content in your mixture is above the norm, it is also not very favorable. The engine can smoke, and a lot of acrid and sticky carbon deposits can form in the combustion chamber and on the spark plugs. In addition, the so-called coking of your piston rings will occur. That is, an understated oil content can lead to premature wear on your outboard or outboard motor parts.
To dilute your gasoline, you should only use oil that is used only for water transport! It is usually labeled TC-W3. This oil contains so-called additives that will prevent the formation of emulsions as well as corrosion and deterioration of your outboard motor.
Any equipment, especially engines, needs timely and high-quality service, so if you bought a boat motor, make sure to use a suitable engine oil of decent quality for it. Very often, for certain models of outboard motors, the manufacturer gives strong recommendations for a specific brand of oil, because all tests were carried out on it and the oil showed the best efficiency.
But on the other hand, one might think that it is profitable for an engine manufacturer to promote a certain oil. Therefore, there is no definite answer regarding the recommended oil, so it is better to rely on the owners' feedback, listen to the manufacturer's recommendations and use not cheap suitable oil.
Since Soviet times, most engines of the Vortex or Veterok type have used ordinary oils of low quality or Avrol for operation, but this gave its own problems in the form of carbon deposits on the rings and the need to clean the muffler.
Today, the main criterion for choosing an oil is the type of engine used:
- 2-stroke - such motors have been used for a long time, boats used to produce only 2-stroke engines. More efficient 4-stroke versions are in vogue today, but the two-stroke engine has its advantages. A feature is that a minimum of oil gets into the crank chamber, if there is an older carburetor engine, a mixture of gasoline and oil enters. If a more modern engine is injected directly through a special nozzle. For 2 T oil, more stringent quality requirements are put forward, it must burn quickly and form a minimum of smoke and carbon deposits on the rings.
- 4-stroke - in such engines the emphasis is more on the amount and pressure of the oil, the engine must better withstand heating and cooling. The requirements for such an oil are quite high, and only certified oils can meet them. The oil should work stably when water gets in, it should also age slowly when working at high speeds. This is very important considering that outboard motors always run at maximum speed.
What kind of oil to fill in a 2 T outboard motor?
In addition to the inscription on the 2T container, the oil must be marked TC-W3, which is officially approved by the shipbuilding association. These markings will confirm that the oil effectively lubricates and provides adequate protection to the mechanisms. High-quality oil must effectively remove heat from all operating engine mechanisms. Make sure that there are no metal anions in the oil, without them the oil will guarantee the engine no carbon deposits.
Among the best 2 T oils, it is worth highlighting:
- Motul Outboard Synth 2T is a famous French brand that produces excellent oils for outboard motors. They comply with the international TC-W3 standard, providing the cleanest "exhaust". It is also interesting that this oil can be used for a mixture in a ratio of 1: 100. One of the best oils for both carburetor engines and models with electronic injection.
- Liqui Moly Marine Fully Synthetic is a two-stroke synthetic oil with great demand in the market. Unfortunately, the oil cannot be called affordable, its cost ranges from 1,500 rubles per 1 liter. The big plus of the brand is the minimum flash point, reduced to 120 degrees.
What makes boat engine oil different?
Compared to a car engine, a boat has a much higher rpm. When, in normal operation, a car engine produces two to four thousand revolutions, then a boat one - five to six thousand. The point is that a boat engine has to work in a much higher density environment. There is also an aquatic environment, which has a detrimental effect on all mechanisms.
It is worth remembering that oil for engines of different strokes is very different.
In two-stroke engines, all moving elements inside the engine are lubricated by supplying a fuel-oil mixture with air. The oil itself is poured into the fuel, with which it burns. This means that such an oil, in addition to its viscosity and lubricity characteristics, should not be smoky.
In a four-stroke engine, the lubrication of the moving elements occurs in the same way as in a car engine, in a closed cycle. Higher demands are placed on the oil here due to the higher rpm. Such oil is not much different from automobile oil, only additives are added to it, which protect against corrosion and perfectly remove gasoline combustion products.
The best oils for 4 T motors
- Motul Outboard Tech 4T - again the lead goes to Motul, the average oil price is 600 rubles per liter. There is an excellent combination of price and quality, on contact with water, minimal emulsion formation is created.
- Quicksilver 4-Stroke Marine 10W-30 is a Belgian oil, the price is slightly more expensive than Motul - 770 rubles per liter. The quality of the oil is confirmed by the ability to fill it for Japanese engines up to 60 hp. With prolonged operation, minimal carbon deposits are created, even when operating at high speeds. Unfortunately, the oil is not so popular in stores, although it has excellent qualities and is tested by many experts.
We figured out which oil is best for a boat motor, you choose based on your budget and recommendations. In order not to miscalculate, choose Motul branded oils, they are very popular and have earned special respect among outboard motor owners.
How much oil is added to the outboard motor?
In outboard motors, oil is not poured into a special container; it must be diluted with gasoline, creating an optimal combustible mixture. If you own a 2 T outboard motor, an increased amount of oil should be used during break-in - a ratio of 1:25.
If you use the outboard motor in standard mode, and sometimes extend long distances, the recommended ratio is 1 to 50. When operating the outboard motor for short distances at high rpm, choose an oil to gasoline ratio of 1:75. In the case of operating the motor in the usual measured mode, dilution in a ratio of 1: 100 is allowed.
It is important to understand that you cannot save on oil, otherwise all components and mechanisms will quickly wear out and fail.
If the amount of oil is exceeded, the engine smokes more, carbon deposits appear on the candle and in the combustion chamber.

Oils for 2-stroke engines differ from motor oils for four-stroke drives in composition and structure. When choosing a motor fluid for a two-stroke engine, you need to familiarize yourself with the principle of operation of this type of power unit, generally accepted classifications and tolerances of manufacturing plants.
The 2-stroke engine does not have a crankcase, it is lubricated with a mixture of oil and fuel, which completely burns out in the combustion chamber of the engine cylinder. Engine fluids for four-stroke units do not come into contact with fuel. Due to differences in the principle of operation, lubricant manufacturers have different requirements for the properties of motor fluids for 2 and 4-stroke drives.
A 2-stroke engine requires oil that will completely burn out in the combustion chamber without leaving sludge and soot. It is important that unburned oil residues entering the exhaust gases are biodegradable.
For four-stroke power units, the main parameter of engine mixtures is viscosity - the ability of fluids to maintain their structure under various operating conditions to ensure the formation of a strong lubricating film on the drive elements.
Standards and specifications
There are 2 oil standards for two-stroke drives:
- 2T - used for air-cooled power units;
- TC-W3 - used in water cooled motors.
According to the API classification, engine oils of two-stroke drives are divided as follows:
- TA - used for motors of small mopeds, motorcycles, lawn mowers;
- TV - for powerful motorcycle engines;
- TS - applicable for the motors of equipment operating on land;
- TD - designed for outboard drives.
Engine mixtures for two-stroke engines of motorcycles and other machines are classified according to JASO
- FA - meet the requirements of developing countries;
- FB - meet operating conditions in Japan;
- FC - smokeless motor mixtures;
- FD - Advanced smokeless motor fluids.
If the fluid is selected correctly, it will extend the life of the motor, otherwise the operating period of the vehicle will decrease.
Watch a video about oils for 2-stroke engines:
Viscosity, base
2-stroke engines have design features; in order to ensure their normal operation, it is necessary to choose an oil corresponding to the viscosity class specified by the manufacturer of the motorcycle, machine and other units. Only the manufacturer can indicate the optimum viscosity for a particular engine type.
If the viscosity is too low, the oil will not protect the engine parts from friction - this will lead to wear of the power unit. The use of a lubricant that is too thick impairs combustion processes, increases friction losses, and leads to increased carbon formation.
When choosing between mineral and synthetic motor blends, follow the rules:
- Mineral water is used in worn out engines due to the presence of a large amount of carbon deposits in them.
- Synthetics are used in modern drives equipped with an injection or dosage system. Synthetic fluids are characterized by enhanced properties; therefore, it is not recommended to pour them into power units with high mileage.
- Observe the approvals and recommendations of the vehicle dealer.
There are BIO oils on the market with accelerated biodegradation. Their price is 50% higher than conventional lubricants. This cost is due to the possibility of combustion products to completely decompose in water; the BIO additive, which is part of these fluids, does not affect the operation of the motor.
Conclusion
Try to buy lubricants with characteristics that meet the recommendations of the vehicle manufacturer. An incorrectly selected fluid will lead to coking of the piston rings, cause increased carbon formation, and accelerate engine wear.
The correct operation of the motor can be ensured by fluids with a competent selection of additives, an excessive amount of which (over 20% of the total volume) will lead to a deterioration in the operation of the drive. Consider: the correct ratio of chemical elements is contained in certified products that meet international standards.
When choosing an oil-gasoline mixture in a 2-stroke engine, pay attention to the dosage indicated by the manufacturer. If your motor must run on a 1: 100 fluid, do not use a 1:50 mix. Your care will envy the drive life.
Almost any modern car is equipped with a four-stroke engine, so most well-known manufacturers develop lubricants for them. Oils for 2-stroke engines are less common as they are more rare. However, they are found on motor boats, motorcycles, chainsaws, lawn mowers. Such motors have low weight and high power density, are cheap due to their simple design and low cost of manufacturing. Of course, such engines cannot be filled with conventional 4-stroke oil.
Features of such oils
It should be noted that such oils are disposable and completely lost. They are not poured into the crankcase in order to lubricate the cylinder-piston group. They are poured directly into the fuel. It is quite logical that the oil for 2-stroke engines burns along with the fuel. If you go into details, then about 25% of the product is spent on waste, the remaining 75% of the oil is emitted into the atmosphere as exhaust gases. The result is an oil mist. In some models, it is introduced in a ratio of 1: 100 or 1:20. The fuel / oil ratio may vary depending on the engine model.
Modern 2-stroke engines have a system that is, the required amount of oil is supplied in accordance with the load on the motor, which allows reducing lubricant consumption.
Operation of 2-stroke motors
It uses a carburetor system for supplying an air-fuel mixture. Due to the principle of operation of such an engine, the emptying of the chamber from the exhaust gases and the supply of the fresh mixture are carried out almost simultaneously. Because of this, some of the fuel and lubricant is escaped with the exhaust. And a third of the fresh grease goes away. This is the biggest drawback of two-stroke engines, due to which the efficiency of the motor is low. Part of the oil burns here, a large amount of emissions is formed. Therefore, in densely populated regions, where mopeds with similar motors are often used, there is a lot of smog on the streets, smoke and noise. An example is the cities of many Asian countries, where the local population's main means of transportation is a moped.
However, in recent years, the design flaws of such motors have been compensated for by the use of new technologies for direct or indirect fuel injection. As a result, emissions have been reduced and fuel consumption has been reduced.
O for 2-stroke engines
There are different brands that produce different quality products. The efficiency of the engine and its durability directly depend on the quality of the lubricant. When choosing oil for 2-stroke engines, you should pay attention to the following criteria:
- Lubricating properties.
- The presence of antiwear characteristics.
- The presence in the composition of detergents that perform the function of cleaning the engine from sediment substances.
- The ability to prevent deposits in the exhaust system. Most often, oil has a similar opportunity in the presence of flushing additives in the composition.
- Low level of smoke in exhaust gases. If, when using oil, a lot of smoke comes out of the exhaust system, then this indicates that most of the lubricant goes to waste.
- Spark plug cleanliness. Many experts recommend checking how dark the candles are after applying the oil. If they are really very black, then it is better not to buy such a lubricant.
- Oil viscosity and high fluidity. Some oils thicken at low temperatures, and then their efficiency is greatly reduced.
- Anti-corrosion properties.
Reviews
If you believe the reviews, then on the Russian market the lubricant from the manufacturer "GazpromNeft" is quite good. At a very low price, the company makes a good lubricant, which is not inferior in quality to the products of world brands. Also good reviews about the manufacturer Makita, which supplies excellent mineral oils to the market. True, they are very expensive. And if the cost of a liter of GazpromNeft grease is 120 rubles, then the price of a liter of Makita grease is on average 500 rubles.
Husqvarna, LIQUI MOLY, LUXE are expensive foreign lubricants that also collect good reviews. You can often read good expert comments on Sadko oils. The products of this company are 85-98% composed of a base - a lubricant, the rest is given to additives to give the composition the necessary characteristics described above. Moreover, all base oils are suitable, from selective neutral lubricants to synthetic polyalphaolefins.
The basics
Good reliable products used in conjunction with two-stroke engines contain synthetic esters along with hydrocarbons. These semi-synthetic 2-stroke engine oils are primarily developed for marine applications. However, mineral-based oils are most often developed for two-stroke engines. They are cheap but less efficient. Considering that oil in any case goes to waste, many owners do not bother and choose cheap lubricants.
By the way, unlike greases for classic 4-stroke engines, for 2-stroke engines, little attention is paid to low-temperature performance. Brightstock, a low pour point additive, is simply added to the oil.
Classification
When it comes to choosing a lubricant for air or water cooled outboard motors, it is appropriate to pay attention first of all to ashless oils. The best manufacturers of such products are Mobil, Esso, Shell, Sadko. They are divided into the following types according to the API classification:
- TSC-1 (TA). This includes oils for small engines with a cylinder volume of up to 0.5 m 3. Similar power plants are used in mopeds and mobile power generators.
- TSC-2. This category includes oils intended for motors with a volume of 0.5-2.0 m 3. Such engines are installed both in mopeds and chainsaws and in motorcycles. They work at high loads.
- TSC-3. Oils of this category are of higher quality and are used on engines that are very demanding on the quality of lubrication. Products for motors of motorcycles, snowmobiles and other equipment with a volume of 0.5-2.0 m 3 are suitable.
- TSC-4. These oils are designed for powerboats with water cooled engines. Considering the fact that such engines are water-cooled, quite high environmental requirements are imposed on lubricants.
There is also a marking of motorcycle lubricants:
- JASO FA and JASO FB - class of oils for motorcycle engines.
- JASO FC - This class includes smokeless oils for 2-stroke engines in motorcycles and cars.
The cost
The average price of oil for 2-stroke engines is quite high - about 300 rubles per liter canister. Moreover, there are products worth 120 rubles and even 600 rubles per liter. large enough, but it is important to determine which oil is right for your type of motor and use it. Using the wrong lubricant will affect the efficiency of the power plant and its service life.
