Amsoil 100% Synthetic 10W-30 Motor Oil 1-Gallon Bottle

Most new engines feature gasoline direct injection GDI often combined with a turbocharger to boost power and improve fuel economy. These new technologies when combined with a poorly formulated motor oil promote LSPI and threaten engine operation. LSPI is the spontaneous ignition of the fuel/air mixture prior to spark-triggered ignition. It occurs in today’s advanced engines and is much more destructive than typical pre-ignition. A properly formulated motor oil is critical for protecting your engine.
