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.

Product Description

Protect the engine in your high-mileage vehicle with STP High Mileage Oil Treatment + Stop Leak. Formulated especially for vehicles with over 75,000 miles, this high-viscosity engine additive includes ZDDP oil additive as an anti-wear agent for protection. This STP oil treatment creates a thick cushion between moving engine parts to help fight metal-to-metal friction. Engine stop leak helps to rejuvenate seals and gaskets and stop engine leaks, noise and smoking to improve performance. Add to engine oil with each oil change during car maintenance. It's suitable for cars, light trucks and SUVs.

    Good, but Didn't Fix
    I think my Ranger has a valve cover leak, but I wasn't sure how big it was so this was my first attempt at trying to fix it out of curiosity. The leak must be too big, cause even after an oil change the leak got bigger as well, so I figured I probably should have left the old oil in there, but I had a reason to change it anyways, so now I go on to fix the leak with new gaskets.Probably did some good as I love this product otherwise!Edit: Upon further inspection, no more leaks after doing the valve cover gaskets, and everything seems to be good! This stuff should now help everything last.
