ULTIMA SYN-GEAR 75W-90 GL-4 (NEW) is a premium-quality synthetic oil for manual transmissions of passenger cars, moderately loaded drive axles and final drives of trucks and for transfer cases of off-road vehicles. Ultima Syn-Gear 75W-90 GL-4 is made based on synthetic base oils with a high viscosity index, with efficient sulfur-phosphorus, extreme pressure additives, corrosion and oxidation inhibitors, anti-foaming and depressant additives. Ultima Syn-Gear 75W-90 GL-4 prevents wear due to instantaneous formation of a strong oil film on surfaces of gear teeth upon increased contact pressure. It reliably protects engines in any climate conditions which significantly extends the service life of heavy-duty gears, bearings and seals. Specifications: API GL-4
