Such oil additives last for about two years with the best functionality. The Lucas heavy duty oil stabilizer generally prolongs the lifespan of the existing oil thus, favouring less oil change and preventing frequent changes.
The main purpose or benefit of these oil stabilizers is that they reduce the oil consumption rate hence, saving a lot. Using it would save you from dry startups and knocking sounds while driving for long distances and it also allows engine performance to be particularly optimized.
How To Fix A Knocking Rod In Vehicles?
