Choosing the right oil is essential for the proper functioning of the engine and its life. The engine needs to be permanently lubricated. The oil helps cool the engine, limits wear and tear on its components and helps keep it clean.
Here is a method in 3 points for choosing your engine oil. It must be adapted to the engine (2 time or 4 time) and have the required viscosity (15W40, 15W50, etc.). It can be synthetic or semi-synthetic: it's up to you to see what is best suited to your machine (maintenance book, dealer, manufacturer's recommendations).

Depending on the type of your engine, 2 time or 4 time, the oil does not have the same use. In an 4 time engine, the oil is only replaced when changing the oil, so it must maintain its efficiency over time. While for longest time engines, it is burnt with fuel.
For 2 time engines, lubrication is done par mixture (oil in gasoline) or par oil injection (separate lubrication), resulting in smoke emission (note that the latest standards for 2-temps oils impose extremely low smoke emissions - ISO-LEG-D standard).
The percentage varies depending on the type of oil:
- 2,5% with a synthetic oil 100%
- 3% with a semi synthetic oil
2T SCOOT Oil
Semi synthetic oil for 2 engines Temps Scooters, with separate lubrication or par mixture which offers a very high protection against wear (mixture at 3% by volume or separate lubrication).
2T SYNTHETIC Oil
2T oil developed from synthetic base for all displacements offering a very high yield. Adapted to Karting, Jet Skiing, MotorcycleCross (circuit or road), it is compatible with all manufacturers and meets the optimal JASO FD standard.
Ester based, specially developed for 2 engines Temps, of all capacities, operating in the most difficult service conditions: competition, circuit, sports and intensive use. Optimal lubrication at all speeds, "anti-smoke" properties, no emission of smoke from the exhaust, perfect control of deposits, does not scale, withstands high operating temperatures and long idling periods, optimizes performance of the motor. It can be used as a mixture or separate lubrication. It meets the most severe standards: API TC - JASO FD - ISO-L-EGD
2T BIODEGRADABLE Oil
Specially developed for 2 time engines of all capacities and of all powers. It ensures optimum engine lubrication in all operating conditions, high speeds, high acceleration and deceleration, long idling periods. Its specific treatment, using low ash technology, protects the engine against wear, rust and corrosion and prevents any clogging of the combustion chambers and exhaust system.
The basis of engine oil can be mineral or synthetic (or even semi-synthetic). Mineral oils, relatively basic, are becoming increasingly rare. They are suitable for old motorcycles little used, and are gradually replaced byar synthetic oils for all modern motorcycles. Chemically improved, these oils are of much better quality. They are therefore essential for sports motorcycles and during a real search for performance.
Chemical additives are components that supplement and improve the properties of oil. In particular, they can increase its life, fight against corrosion or provide better resistance to extreme temperatures. Among the most common additives, you will find detergents and dispersants, anti-corrosion, anti-oxidants, anti-wear and of course viscosity or thickener.
Oils are classified according to their viscosity par cold and hot SAE (Society of American Engineers) grade. Viscosity refers to the ability of a liquid to flow. The viscosity is indicated par a number: the lower it is, the less viscous the oil, the more fluid it is.
Most of the oils recommended by par manufacturers for current motorcycles have multiple viscosity ratings or multigrade type, the most common being an SAE 10W40. This oil has a viscosity of 10 when cold, meaning that it flows quickly in places that need to be lubricated as soon as the engine is running and it offers less resistance to moving parts during starting. The W indicates a winter index meaning that the viscosity has been calculated at -18 ° C. On the other hand, when hot, it has the same viscosity as an oil classified SAE 40 (viscosity measured at + 100 ° C).
The first number before the W therefore indicates the cold viscosity index: the lower it is, the better for cold starts and par very cold weather, less wear when warming up the engine. The second number after the W indicates the resistance to heat, resistance to high temperatures and heavy loads: the higher it is, the less risk of the oil film breaking. You can also choose an index with a wide range of use such as 5W60; who can do the most can do the least. This is very useful in the south, where the temperatures in summer are very trying for the mechanics, especially when moving at low speed in town. Under "standard" conditions, it is important to stick to the recommended rating for your engine.
An SAE 15W40 oil allows a wide range of use. It is ideal for temperatures between -10Â ° C and + 40Â ° C.
The oils are defined par numerous standards, all resulting from tests on car mechanics. There is no “motorcycle oil” standard, neither control nor approval. The mention "special motorcycle" on a container only engages the good faith (and reputation) of a manufacturer, it is above all a selling point to justify a higher price.
The US API, Japanese JASO, and ACEA are the primary bodies that award motor oil certifications. To obtain a standard, a lubricant must pass four engine tests which take into account:
• the rise in the temperature of engine oils in service,
• lengthening the time between each oil change,
• research into engine performance,
• environmental protection standards.
Standards are not an indicator of lubricant quality, but a benchmark for linking an oil to the requirements of a generation of engines. The very latest standards do not necessarily mean a "better" oil, they are defined for particular needs, compatibility with new materials of parts or new requirements. pollution.
1 / to put a specific motorcycle oil (for clutch in oil bath)
2 / do not mix oils of a different nature (synthetic and mineral).
3 / respect the oil change frequency.
You have spotted the viscosity and the standards that suit you and you are faced with the choice of the brand… And here it will be a question of price. To put it simply: the price depends on the brand, of course, but also on the nature of the oil. Thus a 100% synthetic oil is more advanced, more expensive to produce than a semi-synthetic and even more so than a mineral. The selling price will be higher.
Likewise, manufacturers inject more or less additives into the base lubricant to modify the properties of the oil and thus create different ranges.
To sum up: the more additives there are, the more efficient the oil will be and… therefore expensive. Another important note: even if your manufacturer recommends a certain brand of oil, it is only a question of "simple" commercial partnerships ... Anyway, the choice of a brand is a subjective act, the most important being still a to respect the manufacturer's recommendations.
Be aware that without regular oil change, your engine will clog and deteriorate quickly. Engine efficiency decreases, fuel consumption increases and the vehicle pollutes more.
To avoid costly repairs and prolong engine life, be sure to follow the manufacturer's oil change advice!
