Purpose and Specifications

Shell Spirax S3 AX 80W-90 transmission oil (part 550065649) is a high-performance gear and axle lubricant designed for moderate to heavily loaded vehicles, including cars, trucks, and off-road equipment. This 20-liter canister meets API GL-5 and US MIL-L-2105D specs, providing tough protection against wear, pitting, and corrosion in differentials and gearboxes.

It flows smoothly at low temperatures down to -30°C for easy starts in cold weather and stays strong up to 150°C under heavy loads, keeping gears quiet and efficient. Compatible with popular models like BMW 3/5 Series, Renault Clio, Opel Corsa, VW Transporter, and Mercedes.

When to Use / Replace?

Use this oil in hypoid differentials, manual transmissions, and axles under severe conditions like towing, hauling, or off-road driving. Replace every 60,000-100,000 km or 3-5 years in normal use, or sooner (every 30,000 km) for extreme duty to maintain peak protection and avoid costly repairs.

Shelf life is up to 5 years when stored cool and dry. Switching to this oil can extend drain intervals and cut maintenance costs by protecting components longer.
