MOTUL has been partnered with BMW M Motorsport since January, 2020, growing oils for the Bavarian model’s motorsport endeavors. It’s been over a yr since that partnership started and it’s nonetheless going robust. So we determined to test in with the oil maker to debate the model’s latest merchandise and the way it develops oils for motorsport. On this name, we spoke with Nicolas Demaria, Technical Assist Supervisor for MOTUL Americas.
A Complicated Engineering Course of
Growing oil for engines, particularly motorsport engines, is an extremely complicated course of. There are such a lot of elements that may change the efficiency of an oil; temperatures, engine oil pressures, cylinder designs, piston ring designs, gasoline components, and even the design of the engine itself. For example, if a racing engine is a V8, for instance, the oil stress can fluctuate barely between every financial institution. Or the temperatures of every race can fluctuate wildly. Sure fuels that manufacturers use additionally run sure components that may have detrimental results on the engine oil.
So it’s not so simple as selecting a sure oil viscosity and calling it a day. MOTUL goes via an intense, rigorous course of to find out which oil formulation works finest with every engine. Which implies that MOTUL’s technical crew has to have intensive data not solely in their very own merchandise but in addition within the engine applied sciences and specs for every producer they work with.
A motor race is actually damaged down into three phases; coaching, {qualifications}, after which the precise race itself. After every of these phases, MOTUL takes an oil pattern from the engines to find out the way it carried out beneath these circumstances. Then the info from the race oil is in comparison with the info that was created throughout growth, to see if something modified and if any modifications should be made to the oil. For instance, the MOTUL crew have already examined lubricant samples from the 2 BMW M8 GTLM vehicles in IMSA, following endurances races like Rolex 24 and the latest 12 Hours of Sebring.”
Sadly, although, the method of creating any modifications can’t start till the season is over.
“The event course of is so strong that you must do one thing very, very fallacious to say ‘okay, perhaps we messed it up right here’ [to make a change mid-season].” stated Demaria.
The method of growing a brand new oil for a brand new engine structure might be fairly lengthy, additionally. So from the time a producer declares a brand new engine, “It should occur inside a yr, relying on the know-how and the supplies.” Demaria informed us.
From Monitor To Highway Use
What’s fascinating is how the teachings discovered in motorsport translate over to highway vehicles. We at all times hear that from automakers, how their race vehicles educate them the best way to construct higher highway vehicles. Nonetheless, you hardly ever hear about that transition for motor oil. Nonetheless, as Demaria tells us, racing know-how for oil completely makes it to the highway.
“A few of the stuff that was racing oil within the late ’90s, any buyer should buy in [MOTUL] 300V these days.” he stated. Demaria notes that, as a result of engine know-how migrates from motorsport to the highway, engine oil know-how must comply with.

Now, although, exhaust particulate filters are even enjoying an enormous function in oil growth for contemporary efficiency engines. In keeping with Demaria, exhaust particulate filters “are extraordinarily delicate to ashes, both from the gasoline or the lubricant. There’s at all times going to be a small a part of lubricant that will get burned contained in the combustion chamber and finally ends up going into the exhaust stream and finally passes via the [catalytic converter or particulate filter].” This pressured lubricant producers to pursue completely different anti-wear and friction modifying components rising the oil’s efficiency whereas defending the after-treatment programs.
Engine Oil In Hybrid-Automobiles Racing
We have been additionally eager about whether or not hybridization impacts oils and it does. In keeping with Demaria, high-efficiency hybrid powertrains typically use downsized, closely turbocharged engines. To make the identical type of energy as bigger engines, smaller engines with large turbo increase create a ton of additional warmth. So oil producers like MOTUL must compensate for that and develop oils that may deal with the warmth, withstanding, safely, greater thermal stresses than earlier than.
That’s not only for racing, although. Hybrids additionally pose an attention-grabbing drawback for avenue driving as properly, as engines may even be off for lengthy durations of time, leaving the engine oil to take a seat idly within the sump, however then immediately begin again up once more, typically beneath excessive load. So the oil wants to have the ability to carry out its features at decrease than very best temperatures, difficult the components.
So many drivers and prospects really feel as if engine oil is simply engine oil however there’s a lot extra science behind it. A lot of that science is discovered on the race observe after which migrates over to highway vehicles. Which is why MOTUL’s partnership with BMW just isn’t solely useful for motorsport proper now however the applied sciences and classes discovered may even be useful in the way forward for highway vehicles.
