Very very powerful
This is some powerful stuff. I have a 2003 and actually didn't need an oil change or followed the directions to the T. I drove about 40 miles. This morning when I started my car I could hear all the junk it loosened and removed. Now I'm waiting for Walmart to bring my oil and filter. I'm changing the oil 4000 miles ahead of time. I'm just wondering if all that stuff I heard will actually come out of the drain hole. I will update

Does Great
it does loosen the sludge and build up in older vehicles and engines. I have a 1986 Chevy C10 and it does well breaking down the grime in the engine. now no product will completely clean the inside but this product does as well as it describes. I have not had any issues with using this product.

Easy to use
Oil got contaminated with anti-freeze due to oil cooler going out. Ran this in engine for 15 minutes and did oil change. This cleaned everything up.

Changing your own oil?
If your cars racking up the miles or you put off changing its oil on time, like sometimes happens 😏 Give your car some love ❤️ Drop a bottle of this inexpensive STP into your old oil 15 minutes before you change it. Cleans it out and soooo easy 👍

Not sure it worked but it didn't destroy my engine.

I was having low oil pressure issues and some ticking sounds so I ran this through on my last oil change. It helped quite a bit but still is having some problems. I'm going to try again because I think my engine was really gunked up. If I didn't think the product helped I wouldn't do it again so I believe it did help.
