HC-Synthetic High-Performance Low-Friction Engine Oil


FOSSER Turbo Ultra LA is a HC-synthetic high-performance low-friction engine oil for commercial vehicles. The oil is a low-SAPS product with significantly reduced sulphated ash, phosphorus and sulphur content. Thanks to the use of high-performance additives, the oil offers excellent oxidation and high-temperature stability. The good dispersing properties of the product prevent deposits in the engine and on pistons that could otherwise impair the performance of the engine. At very low ambient temperatures, FOSSER Turbo Ultra LA guarantees reliable cold start and fast oil supply to all lube points. It is able to cope with all extreme conditions and to reduce friction loss and wear. It also improves the efficiency of engines as both oil and fuel consumption is reduced and the service life of the engine is prolonged.
