High-performance low-friction engine oil
Properties
Astron Quadro Ultra 5W-40 is a high-alloy USHPD low-friction engine oil. Thanks to the use of fully synthetic base oils and a specially developed additive system, 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, Astron Quadro Ultra guarantees reliable cold start and fast oil supply to all lube points. The oil 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 significantly prolonged.
