when i got the car it had 225k miles on it and it ran ok, but it just didnt seem up to what the other guys were getting outa their cars. so i put oil stabiliser in the motor and in the transaxel. wow! what a difference. i picked up a measured 24 net hp using my g-tec pro SS. can also get over 300 miles on a small 13.1 gallon tank in a very mountanious region! i use your stuff in every one of my 5 cars and tucks! thanks for such a great product!
