Designed to minimize blue exhaust smoke and improve compression in engines that consume and burn engine oil excessively. Based on a superior viscosity index improver material, Oil Smoke Stop is effective over an extended length of time, maintaining oil viscosity at higher level. It may be added at the time of the oil change, and between oil changes if oil cunsumption is very high.

Especially recommended and effective for older, worn engines under heavy load and high temperature operation. Suited for gasoline and Diesel engines to fight blue exhaust smoke, high oil consumption, low oil pressure, and low compression. One can treats up to 4 l ofengineoil. Add to oil while the oil is hot.
