I looked at the LS1 thread, but with 50+ pages I didn't get very far. But right out of the gate the OP states 2%-5% better mileage without any data or methodology. That's a fairly substantial claim given the oil added is merely 0.15% of the fuel.

Mileage data tank to tank varies more than that for me, and even more given seasonal changes, so I think proof of that sort of claim is going to require very rigorous documentation, at least to get any credibility here.

What is the rationale for the fuel efficiency increase? Do gasoline fuel injectors spray more effectively with a little bit of lubrication? Or is there some sort of chemical effect that shunts this thread into unicorn territory?
