About Us
In October 1954, three businessmen with a mere 3,000 dollars in start-up capital introduced the first STP product in St. Joseph, MO. STP, began with one product — STP Oil Treatment. It helped automobile motor oil resist thinning at high temperatures and pressures.

so for cars that have high mileage this is a good product for you but it’s also good for cars that burn through oil very fast. Like mine unfortunately. I’ve noticed since I started putting it in I don’t go through as much oil. Don’t get me wrong, it still burns oil but it’s not nearly as bad. I would previously have to refill it every 3-4 weeks, now it’s around 2.5 weeks or so. So it does work. worth the money. and worth saving your car because the burning of the oil has already damaged my engine so hopefully it will save me from further engine damages.

I was surprised how well this product worked. After 185,000 miles, I was faced with engine oil seal replacement and quoted over $1,100 to fix. My car was consistently dripping oil until I poured a bottle of this product into the crankcase. I was worried because I didn’t want to gum up any critical parts on a car that gets frequent oil changes. But, it seems to have helped tremendously and performance has not changed. An occasional drip occurs but nothing like it used to be.

I bought this product to help with smoke issue going from my exhaust. The problem is not gone and in addition i have check engine light going on every second day.BMW 328xi 2014***Update….smoke issue and check engine went away after 500km. I added extra oil in tank and the smoke came back. ordering this product again!

It’s a thick additive with a tiny bit of adhesion.

This worked great on my engine after I got an oil change. I knew I had a leak but man, it really started leaking after my change. Put this in and it helped slow it down. Good for a while

It’s easy to use and has made a noticeable difference in my car’s operation. A great product for maintaining high-mileage vehicles.

i used this on a 100k mile car that was leaving drops of oil on my new garage floor. used the product and it worked. oil leak stopped. some say its a band aid and that might be true but no more pans under the car or wiping oil off floor, lol i would buy again for an older car.

Did my first head rebuilt on a VW 2.0L TFSI engine. I cheaped out, not replacing the lift pins.Within one minute this product reduced a nasty rattle to a soft purr.
