Howdy ya'll,
Speck sheet shows that my bike's final drive requires 70W80 GL-5 gear oil. The bike has always been serviced at Bob's and this will be the first time for me to change the final fluid. This bike is out of warranty so I don't think that I have to use $$$ BMW oil. The only 70W80 GL-5 I've been able to match up is a MOPAR labeled product and it's nowhere to be found.
I've been using Amsoil 80W90 GL-5 in all my BMW final drives for yrs with no problems.
Finally, my question is, what are the options here? 75W85, 80W90?
What say you?
