Can you use GL3 instead of gl4?
The difference between GL-3 and GL-4 is that GL-4 has a higher lubrication requirement spec than GL-3. And by that I mean there is equipment out there specially designed to test gear oils and simply put a GL-4 oil will sustain more load carrying capacity than GL-3. GL-4 will have more EP additives than GL-3.

What happens if you drive with no differential fluid?
Without differential fluid, the differential would overheat due to metal-on-metal contact. That means it would burn itself out and possibly cause safety issues and require expensive repairs.
Is the differential the same as the transmission?
The differential is a set of gears that transmits engine power to the wheels, while allowing them to turn at different speeds on turns. With front-wheel-drive (FWD), the differential is alongside the transmission inside a housing, and the unit is called a transaxle.
Where to buy 80w-90 gear oil?
Some GL-5 80W-90 gear oils have the old compounds that are corrosive to copper-based metals. If you can’t find the exact product your best bet is to contact an oil company and ask their recommendation. Or, find a European car repair shop that stocks the right stuff and will do the change for you.
What is the difference between 80w-90 and SAE 80?
80W-90 might be a tad thick. Not sure if you’d notice that, though. As you suspect, it’s the second number that counts. Red Line MTL is 70W-80. Might be a better choice. Bror, Thanks for the reply. I take it SAE 80 is kind of an obsolete weight (the car is an ’82!).
