I use this in my Hyundai which only takes a little bit less than 4 quarts of motor oil. I feel that after about 500 Miles of driving I can really  feel a difference. however for my larger cars that takes upwards eight quarts you're going to need a good two to three bottles of this stuff for it to really work. would be nice if they sold it by the quart (gallon)

quantity versus quality

Best engine additive on the market..
I have a 2005 Mazda Tribute S. With a 3.0 litre V6 engine. 167K miles. I use a 12oz bottle with each oil change. Helps reduce noise and friction. Nothing better.. Very satisfied.

PERSONAL INFO

Awesome

I was really excited to learn about this neat new product on the market for worn engines. I got it for a salvage car with bad engine noise to see if it would help, just for the heck of it. And then I had some left over so I put only a cup or less into my Acura TL and Nissan Xterra, both high milage. Mistake. 
First, the salvage car: not sure if it helped. Still sounds terrible,which is fine, it was a try. My Xterra, under the oil cap,had this shiney silver glaze over it,never saw that before. 
My Acura TL and the daily driver of 263,000 miles with never an issue, got that same shine AND developed oil seeps around the engine. I use high milage oil and filters and it never gave me an issue. I was baffled. Only thing I did differently was that additive. When I did a oil change too, the TL oil didn't smell right ..strange thing to say, I know but when I usually change it, it just smells like used oil and on the darker side. This time, it smelled rancid/old fish, a red tint to it, and came out like water. I like this company and their mission but I believe that if you have high milage cars, DO NOT USE because it will make the oil too thin and cause leaks or seeps. They are a good company and they even talked to me on e-mail when I first got the stuff but I just can't recommend using this if you have an older car. If you have a race car and change your oil after every race, Yeah I can see this working for you.

Almost ruined my engine.
