Rated 5 out of 5 by from Oil Change parts Wonderful ... I got Valvoline oil for the car and a new filter PLUS STP oil additive all for $27. That will keep my 99 Camry running smooth for 4,000 miles.

Rated 5 out of 5 by from 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!
