Review: Best - Very good
Review: This is a miracle additive - I bought this additive to mix with budget synthetic engine oil from Eneos for my Chevy Beat Diesel car which has successfully clocked 1.25 Lakh Kms and is secretly jerking and vibrating. After oil change I noticed a miraculous change in the behaviour of the engine like it got a rebirth. All the vibrations and hesitation of the engine vanished like miracle and the engine runs like it's brand new from factory. I'm highly satisfied with this product

## Features

- Application: Add to the engine or transmission oil at any arbitrary time. Recommended for regular use: add fresh additive to the oil each oil change. The contents of the 0.3 l can are sufficient for an oil system with a volume of up to 5 liters.
