Does anyone remember when a car using Mobil 1 last won a NASCAR championship? The last time Rousch won they were using Pennzoil, then there is that Hendrick bunch and their Quaker State. Oh, almost forgot old Smoke won a championship using the JGR oils. Maybe it's time the other 1/2 switched oils.
That's an old ad but interesting and Mobil does make good racing oil but today there are many oil providers as Johnny said.
I still don't like their street oil in my Si. Cleans good....but..
Just a little more HP at the end of a race even if it's racing oil that's what the pros are going to use.
When I raced that was one of things we looked at (oil). No, I was not a pro (far from it) and that was wayyyy back. Cracked up my back and it was over.
