What’s the difference between GL-4 and GL 5?
GL-4 is suitable for hypoid gear service when they are under severe service but are without shock loading. GL-5 is suitable for hypoid gear service under severe service and shock loads and not for use in a gearbox.
Can I use GL5 gear oil instead of GL4?
No, the API GL5 rating does not supercede or cover the GL4 rating. It is important to follow the gearbox or diff manufacturers recommendations and use the correct GL rating.

Which is better Redline or Amsoil?
Initial Red Line testing of an unused sample of AMSOIL 20W-50 Racing Oil in the ASTM D4172 Four Ball Wear Test yielded results consistent with those appearing on the product label. That is, AMSOIL 20W-50 provided nearly three times better wear protection than Red Line 20W-50.
Is Redline good oil?
There’s also a lot of good information out there that shows Redline oil can actually reduce oil temperatures as well as keep your engine cleaner. And the added detergents, ZDDP, molybdenum and ester molecules can really help to reduce friction & engine wear and keep the engine clean over time.
How often should gear oil be changed?
Manual gearboxes usually require a gearbox oil change every 30,000 to 50,000 mi (48,000 to 80,000 km). Automatic gearboxes usually have gear oil change intervals of between 60,000 to 100,000 mi (96,000 to 160,000 km).
