Oily stuff - 5W20

[Grant Lenahan]

big, huge topic that i won’t get into.

But keep in mind - as temperatures fall, a “thinner” oil acts like a thicker one.  Each in fact has a temperature-viscoity curve.

If, due to the cold weather you have, and your use, oil never gets above X degrees, and at that temp it has sufficient viscosity, then it might be fine.

Also, different motors are designed for different viscosities - Hondas want 0w20 most places, i believe.

Some of this is for fuel economy, by the way.

Overall, i would not use a Xw20 in an older (or most modern) audis.  Especially not one with a turbo, who’s oil return line could clog, or where oil sitting in the hot bearing could eventually coke.
