The product is designed to improve the performance of diesel engines by providing a microscopic friction reduction layer on all treated parts. It can be used for cold start, oil leaks, and other problems that conventional oils cannot treat. The additive contains no harmful chemicals and will not harm the environment. Notably, HPOL was launched in 2015 as part of an effort to combat climate change.
