Super Thick Stuff!
This stuff is really thick! It took a while to pour it in, but it seems like it will seal a small leak in my 09 Mariner 165,000+ miles. Only time will tell!

    Hoping for the best
    Trusting in the Brand. Makes me feel good when I pour it in. Engine didn't blow up

    Good in certain circumstances.
    Lower smocking for old care with worn piston ring.

    Excellent High-Mileage Oil Treatment!
    Excellent High-Mileage Oil Treatment for my 93 Honda Accord Sedan! My vehicle has over 263,000 miles and I am the first Owner. Keeps my engine running clean and efficient. STP - the brand and quality of an excellent product. Highly recommended!

    Skeptical at first. Only 3 bucks, why not? It does work. Compression increase is noticable and engine feels smoother. Lasts exactly 3,000mi. (4,500mi full syn) My vehicle is a v8 equipped van, and the $3 investment (every 3,000 mi) saves me about $60.00 worth of fuel per oil change interval. Note: Van has 350,000 miles, so the improvement may be more noticeable on high mileage vehicles.....

    It just works
    It just works. I've used this on two older 98 model cars. Both leaked about a quart of oil every 2k miles. After 2 oil changes this reduced oil leakage to 1/2 quart every 3k miles. I like the added benefits and anti wear additives you get as an added benefit. For an older car I can't recommend this product enough. I used this with a semi-synthetic 5w-30 high valvoline high mileage oil.

    Get this now!
    STP car products are the only one's I use. My current car has over 200,000 miles and runs like much less. Save your car. Use this product line.

    This mixes very well with synthetic oil.
    This product worked very well. I have an S-10 truck with over 100,000 miles on it, and this really did slow down a small leak around the rear main bearing seal.
