Royal Purple...does it make a difference???
Just read an article in a magazine about Royal Purple making a pretty good hp difference (for oil anyway). Have any of you gotten any different results for the LS1's? Thanks.
any "test" i've seen with oils or additives it has been a bogus test.
the one i saw they dynoed a car with 3000mile oil, then changed to their "new" oil, of course it dynoed a little more. but how much was do to the new oil in general or thier "special" oil was not determined
