The main feature of two-stroke oils is that to provide the necessary lubrication, they must be mixed with fuel in a certain proportion. As a result, the oil partially combusts with gasoline, providing an additional volume of exhaust gas. For this reason, there are a number of special oils that minimize smoke and soot formation due to special additives. The best 2-stroke oil is always the one with low exhaust emissions.
Modern oils are highly efficient and can be diluted in a relatively small proportion. Thus, for complete engine protection, you need a little oil. Usually, the recommended proportion is 50/1. In addition, it’s essential to consider the composition of motorcycle oils, which are most often purely synthetic or semi-synthetic. The latter are more common.
If the engine is exposed to heavy loads, as in the case of racing motorcycles, special synthetic oils, designed for racing engines, are the best.

The oil is perfect for two-stroke engines with increased deposit content. Briggs & Stratton 100036 will effectively deal with elimination and return the engine to its normal condition. Special additives in the oil are added to reduce smoke in the exhaust. For proper use, the oil must be diluted with fuel at the appropriate ratio. The mixture can be prepared as quickly and easily as possible. The Briggs & Stratton oil is sold in a transparent 0.48-l white gallon.
What reduces exhausts when using this oil?
Oils that reduce the amount of exhaust are called “ashless.” The reduction of exhaust gases is achieved through special synthetic additives, which do not contribute to the formation of smoke when burning. Of course, the amount of exhaust itself is not reduced but the amount of soot and smoke, in general, is significantly reduced.
Conclusion
Modern oils, compared to those produced a few years ago, show much higher performance and reliably maintain two-stroke engines. Different oils are suitable for racing motorcycles and regular passenger cars. Red Line oils are believed to be the best for racing bikes. For a street bike, semi-synthetic oils by Maxima or Briggs & Stratton are quite good. For racing vehicles, the best ratio is 32/1. For casual riding, the best ratio is 50/1.
Special attention should be paid to oils that reduce exhaust emissions. Smokeless oil reduces the amount of smoke and soot, as well as perfectly cleans the internal system of the bike. In addition, most oils can be used for fuel mixtures, as well as in automatic injection systems. When mixing oil, make sure to stick to manufacturer recommendations.
Frequently asked question
The best motocross oil is racing oil by Red Line (USA). It’s fully synthetic, high-performance oil, which not only protects two-stroke engines but also significantly increases their power. According to numerous tests, engine power increases by 3-5%. The excellent detergent properties of this synthetic oil and its stability allow extreme engine loads.
The Red Line oil can be diluted or used in oil injection systems. An optimal dilution ratio is 50/1, although, in some cases, a 100/1 ratio makes sense. For this reason, when traveling on rough terrains or at high engine loads, it’s worth choosing an oil from this manufacturer.
Most oil providers create high-quality oils and recommend diluting them in a 50/1 ratio, which is optimal in terms of engine protection and high performance. However, there are other oil/fuel ratios, which also have their advantages.
A few years earlier, 2-stroke oils were designed for 20/1 ratios. With modern oils, such numbers will lead to lower engine performance. High-quality oils imply lighter dilution. If you ride a speedy bike, you can try a 40/1 ration. If you have a racing bike, most riders will tell you to stick to a 32/1 ratio. If you’re in doubt, you can use a special table that is available on the official Briggs & Stratton site.
In some cases, a 100/1 ratio is possible, although it has nothing to do with performance. Such fuel/oil proportion does not allow to reliably protect the engine from wear and harmful deposits – it’s just an eco-friendly solution that is most commonly used for two-stroke engines on boats in ecological areas (rivers, seas, oceans, etc).
Oil manufacturers offer a lot of oils for two-stroke engines, especially for enduro and dirt bikes. These oils perfectly protect their engines and increase performance. The oils are usually diluted with fuel and injected directly into fuel tanks but can also be used in oil injection systems in some dirt bikes.
If you own a racing motorcycle, Instead of regular mineral oils, you should use synthetic oils, which are an excellent solution. For example, the Red Line oil is a great option – it’s designed specifically for extreme engine loads. Lucas Oil production, i.e. semi-synthetic or purely synthetic Motul 800 2T, is also a great choice for most dirt bikes.
Mixing oil with fuel is a necessary procedure for the proper operation of two-stroke engines. The correct proportion of oil and gasoline ensures engine performance and its protection. If there’s too much oil, it can lead to a number of negative consequences.
First, the excessive amount of oil in the fuel will definitely provoke increased exhaust emissions, even if the “smokeless” oil is used.
Secondly, the oil can cause poor engine start (especially at cold starts) or problems with engine operation due to the increased fuel density, so you don’t want to mix too much oil.
Thirdly, in some cases, with increased oil content, you may run into carbon deposit formation. All these effects are caused by excessive semi-synthetic oil concentration in fuel. The best ratio is 50/1, except for racing motorcycles.
Two-stroke engine oil can have different markings but it’s intended only for this type of engine. 2-cycle, T2, or 2-stroke oil are the same oils. That’s why there is no reason to worry about getting the wrong oil.
