Does anybody know what oil cars in WRC run? these are 4 cylinder engines with big turbos s i'd guess some form of Full synthetic Xx-40 or 50?
What oils do WRC Cars run?
- Thread starter FCD
- Start date

Whatever they run...it is not buyable for average Joe!
I think no need to be a 0wXx or 5wXx, since they start the race already hot... I'd say 15w50 is a good guess...

Depends on sponsor and engine builder ... Redline. Motul, Mobil1, Ravenol, etc.
If running dry sump (likely) and remote oil tank, they may just pre-heat 50 and fill the tank. Straight grades have no VII's and they change after every event, so not much need for detergents and the like. Prolly very similar to VR-1 Black Bottle or Redline race oil ...

I'd imagine they would run something like Mobil 1 Racing 0W-50 , keep in mind there are some prett cold stages in the WRC calendar, Sweden is in the middle of winter isn't it?
If you google a bit, you'll read from Castrol that they've been working on lower viscosity oils in the cars for a number of years.
"About five years ago, we really pushed to reduce the viscosity,” explains Arnfield. “The lower the viscosity, the less drag in the engine, which means we have more usable power. Together we found significant gains in testing, evolutions of which we now use in the Fiesta RS WRC.”
Of course, who knows what viscosity is "lower".

That's true to a point. But like everything else, it has limitations. I saw an interview with Ray Evernham once. This was back in his glory days with Jeff Gordon. He said at the Super Speedway, 500 mile races at Daytona and Talladega, they used a thin oil for qualifying, but ALWAYS ran a much thicker weight race oil during the race itself. He said if they didn't there was no way the engines would live for 500 miles at those RPM's and temperatures. Now, what he meant by "thinner and thicker" you be the judge.

Well Nascar races are much longer than Rally stages
So what oil was actually in the tin?
It is not unknown for teams to fill whatever oil they want to use into whatever sponsor's can they have. I'm not saying that this is the case for any given team, but a couple of jpegs off of the internet tell you nothing more than what you can see. Maybe they did use that oil - it seems like a good choice - but it is not proof.

Motul 300V is a very good oil i wouldn't be surprised if that's what's really in there
And its the 15w50, the poured one!

I also noticed that the guy in the top photo has MOTUL on his jacket or suit, so I guess he had to at least use a Motul can! Maybe he filled it with PYB 5W30 before the photo was taken...

the bottom pic doesn't look like a race car at all to me., rather a road car with some bolt on upgrades
The top car doesn't look like a subaru at all.
Not sure about the WRC but the US Subaru Rally team used to use Motul like the former WRC team. A few years ago when I was in Vermont, I stopped by Vermont Sportscar and they gave my wite and I a full tour of their facility. Only two people were in the shop because everyone was away at a rally. One room had shelves fully lined with Motul 300V 15W50 and Motul 10W40 Break-in oil. Now they're sponsored by Royal Purple, but I've still seen a few random Motul bottles in Vermont Sportscar shop pics.
Ohle - That's definitely an open class Subaru rally car in the top pic above.
