I use this product by STP for my high mileage truck as an oil treatment & stop leak prevention. I trust STP products and so far I'm liking the oil treatment too.

Great product as I have an older vehicle and I've seen great improvements by using this product I see that it keeps the engine lubricated as well as protects it from any week leak it may have as it's a 2000 Ford expedition

On my 2000 Ford Expedition

Satisfied customer

Best price

Had a small leak on oil pan,2002 Monte Carlo SS,put 1/2 in this car and the other 1/2 in a old truck.Took about three weeks to stop the drips.This stuff looks just like the old STP back in the 60's.

Worked for me.
