well since we&#39;re all here confessing....my name is Chris....I have a spoiled rotten truck, its a 99 ecsb Z71 that only takes 93 gogo juice and synthetic oils, anything else is denied&#33;

Hey man, just noticed your sig included the synthetic oils part. I just read an article where they dyno&#39;d a truck prior to switching to all synthetics (gears, tranny, oil) and after the switch they showed a gain of 10hp. Sounds almost too good to be truw - picking up 10hp from a fluid change, but worth a try&#33; Did you notcie a significant difference?

Two guys garage did the synthetic oil change in the engine and rear end and gained 9HP. Not a bad gain for little investment. They used Royal Purple, of course.
