I personally support RXP. It's in a little red bottle. I had a 1970 Buick Skylark with a 350 that got roughly about 10 mpg. After adding the RXP I started averaging around 13 mpg.

I've used it in every other vehicle I've ever owned, and not that I've noticed much in gas mileage increase, but the car seems to run better and definitely cleaner.
