Ok, I'm completely screwed at this point because of a series of purchasing department FUBARs. My ATS diff oil that was promised for today won't be here until Monday at the earliest. Diff is in the car, no oil yet. Must load Friday night for MidOhio and the Runoffs. Still have to do the break-in and fluid change before leaving.

Has anyone running track events had success with other more readily available fluid in an ATS carbon diff? I cringe at the thought of potentially messing up a brand new diff.

 

Just got a call; supposedly they found a place the could over night it from NY. Why NY can over night it when MI could not I have no idea but now they are saying it will be here tomorrow.

I'd still like to hear if there is another fluid that works, so I can something locally instead for the future.
