Getting ready to order fluids for spring tune-ups, and was wondering if Redline 75W90 is the right fluid for my primary case/transmission on my 07 1200 Custom. It is a GL5, and from my searching, it looks like others have had good luck with Mobil 1 75W90 GL5 oil. If not, what Redline fluid should I use?

Thanks for the help.

The Redline should work. Might be easier to find Mobil 1 75 w 90 gear oil. That's what I use..

 

Yep, Mobil-1 75-90 syn Gear Oil. At any Autozone for about $9.00 qt.

 

My bad on double post. Sorry.

 

I'm going to be placing the order on-line for oils for both the vette and the harley, so availability is not an issue.

Thanks,

Jason
