what syn oil to use?

[Fred Munro]

The older engines are not designed for 0 weight oils. Use the oil weights
your owners manual recommends for both syn and dino oils. For your car, it
is probably 5W30 or 10W30 for winter and 10W30 or 15W50 for summer. I use
Mobil 1 10W30 year round in my '94 S4.

Subject: what syn oil to use?


I rebuilt my 1990 Audi 80 non-q 4 cyl engine. Now I want to use synthetic
oil in it, but I am not sure what grade to run. Castrol  treats it as a 12
yr old engine and recommends 30w with no syn listed. Mobil –1  doesn’t know
either.
My temps here run from 10-100f and I am thinking of using 0-40. Anyone with
a suggestion??
Thanks.
