Should I expect a mpg increase with M1 or is that just marketing hype?
I'm with Patman too on this although I wouldn't have an idea about % difference. For instance, I'm sure I've seen a decrease with GC vs. M1 but it's not because M1 is anything magic. It's because it's thinner...quote:

I agree with Patman. And its difficult to impossible to have good enough controls in normal driving to see any difference. Just too many variables. I never noticed an increase. when I went to Mobil 1. But oddly enough I am seen an increase with RedLine. I am though also aware of the variables.
