I ran the Joe Gibbs Driven 10w40 in my 10 second pump gas Duster, no problems. I'm running Lucas 20w50 oil in my Hemi now just because Summit had a good deal on it.

That was my thinking too, usually what ya want to spend at the time and I figured the Driven GP-1 is about the same price as most other racing oils, guess i'll give it a shot. I only race the clock, so if there's any gain there then that's a plus.

And not very much of it either with low drag, low pressure, low volume oil pumps!
