Yes flame suit needed. I am a retired NASCAR guy. Started out in the engine room at Bobby Allison shops in Al in 1968. I have assembled more engines than I care to remember. I think bout 2,300. Lots of R&D work in the day. My twin Brother was the go to guy for GM assemblies in the 70's and 80'0 into the mid 90's. R&D such as rod stroke ratios, bore stroke ratios, Various valve timing and rocker ratios depending on the power range we were trying to achieve. Restrictor plate issues, then the plastic oils were introduced in mid 80's, dropping what we know as frictional HP, Am I throwing big names around here, yes to make a point. My brother has headed up a couple engine shop in Charlotte that have leased engines to teams that have won the Daytona 500, 4 to be exact, with drivers you have heard of. I converted to chassis development in 1976. I have worked with Davy Allison, Neil Bonnett, Built practically all of Harry Gant Nationwide stuff. Heres my point. if Mobile 1 oil can be run in a Cup car, Nationwide or the trucks, its good enough for Porsche. I have seen it all in the engine room. Yes there are other good oils out there, I run MOTUL in my 550I, but make no mistake about it, the NASCAR engines are second to none. The only other oil I would consider is the Joe Gibbs oils, recommended highly by a few friends still hanging around Charlotte.
