Anyone document their fuel savings using PAO based oils from the same viscosity dino oil? Extended drains itself help offset the cost of $7.95/qt Redline. But what if there really is a fuel savings. That would be really nice after 12000 miles, I saved X gals of gas to complete offset my initial purchase of my Redline. BTW I will be going to Redline after I put 10000 miles on my new superstroker. Thanks!
