Rated 5 out of 5 by Bumblebee7 Excellent product
Been using this product for my 4Runner with over 203,000 miles on it. It works extremely well on it. I use it after every oil change to keep it running smooth.

Rated 5 out of 5 by Verified Reviewer A must-have for older cars
When cars get old, the cylinder walls start scoring, resulting in loss of compression, power and increased oil burning. This stuff fills in those scores and gives old cars some of the pep it had been missing and slows down oil usage. It is a must-have for old cars.

Rated 5 out of 5 by drlh This Works!
There are many ''fix it'' products that claim to do it all. But it was an article in Hot Rod Magazine that convinced me of the validity of this one. I had a 1950 jeep with lousy compression and this brought it up to spec. I use it in every car at every oil change. It fills the small scratches in the cylinder walls and elsewhere to increase compression and tighten the other tolerances. Oil pressure increased as well. Good stuff!

Rated 5 out of 5 by extraterritoriality A valuable add-on to each oil change!!
Of the various oil-change "pick-me-ups" available in the automotive market, this is the one I always remember to put on the list when I'm doing 3000 mile interval oil changes. It helps keep the compression up!!

by parlaypaul Best engine restorer product period!!!!!
I have owned 4 cars in my life and used Engine Restorer in all of them. 2 of them went 300K + miles , 1 of them went over 400K miles and the other is still going at 465K + miles. I think that this the best product on the market today!!
