I'm sure just about all of us have ssen this stuff at the auto parts store, but has any one ever used it? and if so what do you think of it? I looked around the web for a bit but the reviews are mixed and hard to tell who is full of it.

 

I wouldn't put it in my H3.
I've used it in the past on an old truck I had. It's a synthetic additive that is suppose to help seal up the cylinder walls and improve compression. I didn't notice any difference, and I think it's just a "snake oil" type product.

 

I used it in an older Dakota (3.9L V-6) w/ 140Kmi, and I did notice a small difference in performance, and oil consumption went down a bit. I wouldn't bother putting it in an H-3 though as it is really more for old motors with a lot of wear.

 

Yeh I was not really thinking of using it in my H3 althought I do have 63,000 miles on it. I was more intrested in any opinions from people who have used it. I will probably test it out on my girlfriends 98 Ford escort ZX2 with 128,000 miles first and see how it does.
