FAQ

What is GL-4 transmission fluid used for?

GL-4 transmission fluid is used in manual gearboxes and synchronized transmission systems requiring moderate extreme pressure protection.

What is the difference between 75W-80 and 75W-90?

75W-80 offers lower viscosity for improved fuel efficiency, while 75W-90 provides stronger protection under higher loads and temperatures.

Can GL-4 be used in all manual transmissions?

No. Always check manufacturer specifications, as some transmissions require GL-5 or specific OEM fluids.
