[R129 SL] Non SL but an oil (Mobil 1) related question

[Steve Sims]

Gee, Tom...  Having nothing but my prejudice to rely on, I'd recommend
Mobil-1 15W50 for all of them, year round.

That's what I use everything in own, right down to the lawn tractor.  And
while it doesn't get quite as warm in Richmond and it does in Hereford, it
does get quite a bit colder, and the 15W50 is still fine.

I don't have any way to "de-mystify" the question, beyond telling you what I
do, and what works for me.
