Anyone using Mobil 1 0W-40 on the race track?

I've noticed that a lot of companies have now adopted "recommended for". No one can dispute that. I can "recommend" cooking oil for Ferraris if I want...

Mobil does make a racing version of their 0w40 I believe.

Nope. They offer a 0W-20 qualifying oil and a 0W-30 race oil. The regular 0W-40 is the oil specified by Honda Performance Development for their IRL engines, though.

I just got a UOA done on M1 0W-40 after the oil saw 2 hours of hard race track driving. Here is the link for my UOA:

The UOA looks good, so I will continue to use this oil on the track with full confidence.

Porsche doesn't seem to agree with you. They just ran it at LeMans.

Well...I feel better about running M1 0w40 in my Ford Explore now.

My opinion is that you should change the oil after every track weekend, and not arrive at the track with more than 1000 miles on your oil.

My other opinion is that 10W-40 oil is considerably superior at track conditions to 0W-40 oil. In particular, the HTHS numbers are usefully higher.

I obey these rules on my Ferrari F355B.
