alicias Posted May 7, 2004 Share Posted May 7, 2004 I saw someone test a product called exp4 on the speed channel a couple of weekends ago. i don't remember the vehicle but they got a 5% hp increase from two bottles -- one oil treatment and one gas treatment. the increase was attributed to the product's ability to cool things down - the engine -- whatever. i put in a bottle of each last night. i had a full tank of gas and and oil change not too long ago. maybe i'm crazy but it seems like Mountain Dew for cars. its like the difference between having the ECT on and off ... here's the site: http://www.exp4additives.com/products/?feature=1 it sure made more of a difference than upgrading the air filter to a k&n. i'm satisfied with it.

Alex-us Posted May 7, 2004 Share Posted May 7, 2004 I can't speak for that stuff, but one snake oil I've used that actually works is Sea Foam http://www.seafoamsales.com/motorTuneUpTechGas.htm Amazing how much gunk it'll clean out. Quote Link to comment Share on other sites More sharing options...
