Who is Motul?

Motul is a global French company which manufacturers, develops and distributes lubricants for engines (motorcycles, cars and other vehicles) and for the industry. Today, they are present in more than 80 countries and designs, elaborates and distributes lubricants with higher technical value added. As a pioneer in many synthetic and semi-synthetic products, Motul has always favored innovation, research and development. The company is also a leader in the motorcycle lubricants market in France. In the motorsports field, many manufacturers trust Motul for its technological developments in car/bike racing. Motul has thus developed close relationships with manufacturers such as Nissan, Yamaha, Subaru, Toyota, Honda and Suzuki.

Motul was the first lubricant manufacturer to use the ester technology for the formulation of its 100% synthetic car oils by capitalizing on an innovation first invented for the aviation industry. The vegetable-based esters benefit from lubricating properties, anti-shear quality and exceptional resistance to high temperatures. “300V”, Motul’s flagship range, experienced great development thanks to its presence on the most prestigious car/bike races. Motul’s research and development capacity is divided in two entities working respectively on “Automotive” (automobile, two-wheels, boat) and “Industrial” lubricants.

An oil is only as good as the base stock and additive package. Higher quality synthetic oils contain very balanced additive packages with high quality ingredients. There are plenty of aftermarket oil additives that promise reduced wear, lower temperatures, and better gas mileage, but many of them are just high doses of additives that are already in the oil you buy off the shelf.

Motul uses PAO based oils for the 8100 X-cess line, while the 300V line and 8100 E-tech (short for “Ester-technology”) are made from Esters. Ester based oil molecules also carry the added benefit of having an electrical charge. One side of the molecule has a positive charge, while the other has a negative charge. This means that ester based oil molecules are always going to build up a layer of protection between metal parts during cold starts.

What about the rest of the fluids?

Motul’s line of gear oils covers nearly all types of transmissions used in street and racing vehicles. The synthetic base stocks used in Motul gear oils resist breakdown from shearing stresses and high temperatures. Gear 300 is an ester based 75W90 gear oil that meets GL-4 and GL-5 standards, which makes it an excellent choice for limited slip differentials and manual transmissions. For heavily loaded differentials, gearboxes, and transaxles, Motul Gear Competition FF is also an ester based 75W140 gear oil, but it has been specifically formulated for the extreme temperatures and stresses seen in racing and track driving or even with high horsepower adders such as turbos and superchargers.

For the modern brake system, they have formulated a DOT 5.1 brake fluid that features very high dry and wet boiling points, low viscosity for enhanced ABS and traction control operation, and extended flushing intervals (2 to 3 years). For track use, the RBF600 is an ultra-high boiling point fluid (593F dry) that is perfect for brake systems that see extreme temperatures from racing.

Motul Inugel coolants are coolants that are free from phosphates, nitrates, and amines, which eliminates contaminant build-up in the coolant system. Since Inugel Expert Ultra offers superior freezing and boilover protection over Original BMW coolant, we recommend a 40-45% concentration of Inugel coolant in distilled water.
