Red Line MT-90 Gear Oil
Red Line MT-90 Gear Oil is a perfect upgrade for those with M56, M66, and M59 gearboxes.
Red Line MT-90 gear oil is some of the best manual transmission gear oil on the market today. As a 75W90 GL-4 gear oil, it offers quicker shifts, and perfect synchronizer coefficient of friction. It is also safe for brass synchros, as found in most Volvo gearboxes, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage. Furthermore, MT-90 offers high performance gear protection while increasing synchro life. Finally, it eliminates notchy shifting, even when cold.
