i run 1 quart of the lucas oil oil stabilizer with 10 quarts regualr oil..it makes it heavier duty..but i dont know about their fuel additives..as far as im concerned it just makes the cost to fill up a tank more expensive
Their fuel additives do nothing. They ranked near the bottom in a publication of additives. I even tested it. My injectors were sticking, I used some, and no change. Then I got some Stanadyne Performance Formula. Haven't had an injector stick since. Plus it cleans the fuel system. It's also made by folks that make fuel injection systems. My rule of thumb is not to buy any additive from Wal-Mart or the "cookie cutter" auto stores.
If you have a fuel injection shop you may be able to get it there. If not, you can order from genosgarage.com or diesel manor. I'm sure there are other places online. I have a shop here. Genos has a good price though.
From what i have experienced...Lucas is not good at cleaning injectors OR fuel. It DOES however, work great at lubricating your fuel system, Injectors, pumps, etc. RBP has a great additive from what i have heard, that claims a 10% increase in fuel mileage...if its true...i cannot say for sure.
