STP High Mileage Oil Treatment + Stop Leak - 15 FL OZ

Works as expected

STP is always a good product.

i bought this because it has ZDDP, which my old engines require, and it has a seal additive to help reduce leaks which can be common in old engines. So this is a great product because it claims to deal with two issues. I will continue to buy this.

Primera vez que utilizo este producto, volveré a dar mi punto de vista al final ,pero tiene buenas recomendaciones y espero funcione como tal

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.

So my car is a `96 make & model, it was running well, and then after using this in the oil, some time later my car broke down with a strong smell coming from it. It turned out that the oil distributor had actually corroded at the seal and started leaking, when this is supposed to seal leaks in the system. My mechanic ended up having to install a kind of system bypass, because the supplier could not provide a replacement oil system and seal. It ended up costing about a grand for the repairs and cleanup. I bought this to take better care of my car and lubricate it better, but the product seemed to have actually damaged my car to the point that it needed serious repairs and modifications. It should have left it running better than ever, but instead it caused a serious breakdown, and it was by sheer luck that I was able to get it started and leave it with the mechanic. It might work better with your car, but I think given the chain of events, and the amount of time that it had to prevent exactly the problem that occurred, it is fair to say that you might do better taking it for an oil change and getting the additive put in by a professional.

Solid product in my 2012 E250 with over 400 thousand k’s. Stopped the leak & saved my driveway Buy with confidence

Good

Like this product. Never had a bad one. I had a problem with the engine

Good stuff, had a pretty bad oil leak on my 08 Audi A6 caused by hardening of the o-rings on the VVT. Replaced those and added this on the oil change to be extra safe. Completely stopped the leak and honestly felt like it drives a bit better too. Will probably just use this on every oil change from now on.
