Additives are active ingredients in the fuel, lubricant or coolant, which can emphasize positive characteristics such as power and fuel efficiency, whilst reducing negative things such as friction, sludge build up and emissions. RAVENOL have additives for many applications, including cleaning, wear reduction, fuel quality improvement, corrosion protection and improvement of performance.

RAVENOL fuel additives can help you save even more money on top of using our already fuel-economic engine and gear oils, because the additives go beyond the lubrication process and actually improve the efficiency of the combustion process inside the engine. And through regular use of other RAVENOL additives for cleaning, conserving and maintaining the engine, you will notice a return to full performance and cleaner emissions.
