Rated 5 out of 5 by Work grate My old 1985 Dodge has almost 150000 miles on it It use to burn 1Qt of oil every 1000 miles witch seem to be the norm for them 318 ci as i had a few .Then i started to see a lil blue smoke at lights. I new it was ether valve seals or the ring's so being i was really hoping to get another 50000 out of it before rebuild.I wasn't happy.Then i saw the STP Thor t i will give it a try.Not only did the blue smoke stop but when i chk the oil at the next 1000 mile mark it did not burn any.I still don't believe it so next 1000 mile mark we will see .I do hear a Lil lifter noise in the morning for a very short time sometimes .

Rated 5 out of 5 by It works! Been using STP oil treatment for 60 years in about 400 different cars, trucks, and race cars. Pouring it you can see why it works and that it is the same as always. You have to use it! November 9, 2014
