The owners manual for my winter car, an '87 Audi 4000 Quattro, allows the use of 15w50 down to 0F. I sometimes take in on winter trips, though, and it can be exposed to overnight lows lower than that. 10w30 or 40 is good to -10F, and 5w30 to -20F.
This car burns some oil, even running the Delvac, so I'm not thrilled with the idea of running a thinner oil. Plus, it's rare that the temp is out of range for it, and D1300 is both cheap and good (wow!). So...
Do I just add a quart of M1 10w30 to my 4 quart sump? Tough it out with D1300? Switch to something else?
All input appreciated!
Regards,
Robert
