hi..
where are you getting information that says a conventional non-synthetic
engine oil is only good to 85 degrees F ambient ?
that makes zero sense..
as it's well over 85 F a LOT all over the US in the summer.
if you want to talk about 'oil temp' ..yes....
that's a limitation for sure ,
and synthetic oils stay healthy at higher temps than non-synthetics.
And a non-synthetic driven intelligently can be ok.
to be really on top of it , an oil temp gauge is a nice thing to have on
your rig.
personally ...
I probably would not put a full synthetic in an engine with that many miles
on it ..if it's the original engine, or bottom end at least.
in 83 it could be an air-cooled vanagon,
or it could be a 5 speed diesel vanagon ..
and you probably have an 83 1.9 waterboxer.
Scott

Subject: Synthetic Oil selection?
Questions: Is it ok to switch to synthetic oils in my 83 vanagon with
193,800 miles? The multi-grade is only good to outside temps of 85*F, will
that be a problem to use in hotter climates?
