If you read the makeup of our famous Rislone Engine Oil Supplement with Zinc Additive, you will notice that it focuses specifically on zinc, which most other additives don’t. More specifically, it contains zinc dialkyldithiophosphate, or ZDDP.

You might know something about engine compression, but in case you don’t, here’s the crash course.

Your engine relies on compression during operation to pressurize the fuel and air mixture so that it detonates properly and creates power to push the pistons. If your piston rings get worn, they allow this gas and air mixture to escape and your pistons can’t create the right amount of compression. Car engine compression problems can be hard to detect at first but can cause big problems if left to get worse. And for you enthusiasts out there, compression = power.

Our engineering and tech support teams here at Rislone have put together this list engine compression loss symptoms to help you identify when your engine is suffering from low…
