FAQ- Motorcycle

Why are oil drain intervals shorter for motorcycles compared to cars?

Unlike with cars, the capacity of  motorcycle oil sumps are generally limited given the low overall dimensions of a motorcycle engine. For scooters in particular, their capacity is often less than 1 litre and for some applications dry sumps can also be used. (this is when the oil sump is located remote from the engine)
Given these lower volumes of oil in motorcycles and the increased constraints put on the lubricant, such as higher temperatures, multiple lubrication (engine, gearbox and clutch) and extreme RPM - oil drain intervals are shorter for motorcycles than for cars.
However, we advise that In any event you should always refer to the OEM's recommendations for the correct oil change intervals.

300V Factory line, 7100 or 5100?

Choose your oil depending on use and riding style:

300V Factory Line lubricants are especially formulated for the severity of racing applications.  Based around the Ester Core® technology, 300V Factory Line lubricants provide the best engine response and protection at very high temperatures and RPM, throttle feedback, clutch feel and ultimate gearbox protection.  Four viscosity grades are available for track/road applications with 100 % shear stability and constant oil pressure and two viscosity grades are available for off-road with optimal traction.  Developed  in close partnership with Worldwide Factory Teams, the 300V Factory Line range of lubricants are also available to the general public who demand only the best!
7100 is Motul’s dedicated 100 % synthetic range of lubricants for modern high performance 4-stroke motorcycle engines. Ester technology and optimized additives ensure clutch compatibility, gearbox durability and power response from the engine. With a variety of viscosity grades to choose from, you can be sure to find the right lube for your bike and your riding style.
5100 is Motul’s Technosynthese® range of lubricants formulated with esters. For the price conscious, you can still be sure that this range of lubricants is certainly not lacking in performance and protection.   They are especially formulated for the highest possible reliability for more general everyday use.
For sure, the requirements of a lubricant for normal everyday use of your motorcycle are entirely different from those of the demands of racing.
Motul 7100 and 5100 have been formulated so that you can meet the OEM's recommended viscosity and oil drain intervals without any issues under normal daily use conditions.

Until now, I have used a competitor's oil in my 4-stroke engine motorcycle. Can I use Motul without damaging my engine?

4-stroke engine oils are compatible with each other and can be mixed.
You can therefore safely use a quality Motul lubricant in your motorcycle from now on.

Can I mix two types of oil of a different quality or brand?

We can only recommend that you mix two different brands or qualities of lubricant only if the two oils were designed for the same application (4-stroke engine oil for instance, but you can’t mix a 2-stroke oil with a 4-stroke oil). However, make sure you comply with the minimum quality recommended by the OEM, bearing in mind that the quality of the mixture obtained will generally be closer to that of the lesser product, depending on the proportions.

I am currently using a 15W-40 oil in my motorcycle engine. In very cold weather (-10 °C), when starting, I hear a clacking sound. What should I do?

Your engine probably operates with hydraulic pushrods. At low temperatures, a 15W oil is too viscous to ensure the proper operation of such parts. You should therefore use a 10W-40 or 5W-40, depending on the OEM's recommendations – please refer to your handbook that came with the bike or contact your nearest dealer.
