What sold me on NOT using Lucas is their web site. They did not show
any
test results, they based all of their success on Testimonials. I am
leery
of Testimonials.


I've used Lucas, and I imagine it's as good as anything els.

I've run straight oils and think they're about as good as anything else
too.

I really haven't seen any evidence that shows oil additives have really
helped performance, engine longivity, , or economy, on anything.
