I saw a test of EXP4 additives on Sports Car Revolution on SpeedTV, and they saw a 5% gain in HP on their dyno test. Normally, I wouldn't believe anything like this, but these guys also do the Dream Car garage and seem to be reliable. They also didn't believe the results, but the dyno showed the actual gain. Was just wondering if anyone had any experience with it. May try it on my next oil change just to see what it will do.

 

Try the fluids and lubricants section & the bobistheoilguy website...

 

Do what you want, but I'm a firm believer in keeping additives to a minimum. The only additives I ever use are fuel injector cleaner. If you were to really see gains, and I am skeptical about that, you're going to be sacraficing something along the line. My guess is that it's going to affect longevity, in which case I'm going to stay away from this stuff.

 

Garbage, only oil additives that are shown to work are LC20 and ARX

 

The only liquid that should be in your crank case is oil.
Just keep it clean.

 

It was an impressive dyno test, but then again, they are a sponsor of the show!

 

Yup. Mobil 1 works great, but was just looking to see if anyone here had experimented with this product. I figured someone would have been all over it based on a cheap cost and soooo much money being spent by Forum members on car stuff!
