The synthetics of Motul 6100 and 8100 will behave better than many of our competitors in racing engines. But if only the best will do, if hot spots can reach 350 C/750 F, your race engine needs Motul 300 V. In 300 V, the best Ester synthetic technology has been adapted from Jet planes to car racing: ultra low-friction for more horsepower, oil temperature up to 185 C/365 F, 0% shear loss to keep full protection past the finish line!! 300 V Esters will also leave a film to prevent metal-to-metal start-ups. Over the years, Motul 300 V has been used in the most prestigious race engines, ranging from Formula 1 to World Rally Championship to 24 Hours in Le Mans or Daytona. Many car manufacturers have had race programs running on 300 V, thus contributing new testing to the ever improving formula. The 300 V you buy is the real thing, not a "look-alike" product!

Only the racing series is 100% ester. Does anyone know how long you can run the 300V 0w-20 oil?

The rest of their oils are blends.

Don't know the answer to that one buster. I know that it is said that it's one of the best ester based oils, but I didn't find a VOA for that particular weight, and I don't know if the TBN level would be the same from the 5w40 formulation to this one.

Maybe someone using this weight might considering doing a VOA?

TBN for 300V high RPM is 11.3, in case you want to know.

it is safe to follow what the OEM recommends.

I don't think it's 100% ester.
Some people claim it's only 30% ester , the rest PAO.

Motul plays games with the word "ester" I was told.

"The Motul uses double ester as a base stock, blended with PAO. And has around 25% ester content."
