[T3] Stupid question #395 Oil change time?

[Jim Adney]

Followup:

Yes, W stands for Winter. It refers to the viscosity as measured on an 
arbitrary scale at 0 C.  

I should have mentioned that '72-3 Type 3s, with PCV, will have less trouble 
with crankcase condensation that the earlier years.

With a little bit of searching, I find that STP has just enough ZDDP to be able 
to claim it in their blue bottle product, but not enough to actually be useful. 
That's probably also little enough that it won't damage Cat Cons.

I also came across a note mentioning that straight weight oils do not have to 
meet the modern API low zinc requirements, so we might want to look for 
straight weight oils.

Note that our owner's manuals recommend SAE 30 for outside temps from 
freezing to 110 F.

I found one other comment that mentioned that Tractor Supply Company 
commonly stocks straight weight oils. That's worth looking into.

Finally, I came across this: a discussion of what fuel hose is good for 
modern gas. The good news is that anything meeting 30R6 or 30R7 is good.
