Playing Devil’s advocate how do you (or anyone else) know who’s oil is the best?

I talked to Lake Speed Jr. at Joe Gibbs about what oil to run in my MOD motor and they have one that is a 5-20 that he says will hold up to Racing temps and such. The price is very high.
Here is the e-mail string.

Jerry,


Our new FR20 should be ideal for that application. It is a 5W-20, and it has a very high viscosity index to protect your engine under higher temps.

Thanks,

I race in NASA’s Camaro Mustang Challenge series. This is road racing. I run a 2002 Ford Mustang with a 4.6 mod motor. We have to run stock engines and we are limited to 260 HP/310 TQ but we really push them hard and at high rpms for 30 to 45 minutes. Ford says to run 5/20 oil in this car as a street car but I worry about it in a racing situation. I don’t know the oil temps but I’m in Texas and I’m sure we are pushing 280-300 on hot days.

I would like to know what oil and at what weight I should run?


Thanks for your help.

Jerry
