I was watching a show on the Speed Channel yesterday called Sports Car Revolution. They put a prodfuct to the test called EXP4 Oil enhancer to the test to see if there would be in gains in horsepower. There are so many product out there of this kind, that claims to increase horsepower and reduce friction. This product actually is ligit, and the dyno resuts don't lie. There was actually a net gain of nine horse power to the wheels as a result of using this product. Has anyone used it? Here is the site http://www.midwayauto.us/detailedpro...tion.asp?11772 and click the video to see the episode of sports car revolution

 

thanx..just ordered ATF additive, oil enhancer and fuel additive

 

I believe it; I've been using another product now for about ten years, cost was about $120 a gallon, but only takes a few ounces per oil change.
The stuff adds about 5% hp according to the manufacturer(PowerUp in Canada).
Every time I change my oil, and don't put the stuff in, I feel the car fall on it's face, guess I'm still skeptical, but then wind up adding it again for that bonus hit of hp.

I'd be a bit leary of the ATF additive in our cars; the tranny oil requirement is unique to our tranmissions.(FYI)

 

Royal Purple does this as well and has a proven dyno track record. I think in the 4-5 HP range.

 

FYIW, the President and CEO of that company drives an LX450 and his wife an LS430, and they use the product in the vehicle. He brings the products in to the dealership when he has his oil/tranny done, and the dealer has yet to hassle him or deny warranty work....According to the CEO, the is an authorized Lexus repair center in Dallas that uses their products for all the cars they service....I have also ordered some of this stuff....

 

nice find man thanks for sharing

going to get some myself

 

ditto...nice find! I always heard about stuff like this, but was always a skeptic...good to hear that there are other Lex owners who are using it and actually experiencing gains...
