RE: Oil Viscosities

5W50 will give you a hotter temp. range with the same low temp range. With
dino. oils, wide viscosity ranges are discouraged due to the stabilizers
that must be used, but are possible with (and one of the advantages of)
synthetics. The other synthetic which was designed specifically for cold
temperatures is Mobil 1's 0W30.
 
There is an oil FAQ out on the net somewhere, but the shortcut I have to it
points to an old one that is no longer there.

Subject: Oil Viscosities


I live in Edmonton, and therefore deal with some relatively cold winters, it
can be as cold as -40C or as warm as -5C regularly.  I have been running
Castrol Syntec 5W30 oil in my '96 Jetta.  Today I went to two department
stores looking for Syntec 5W30 and the only thing that I could find that was
close was Syntec 5W50.
My question is, what difference would using 5W50 as opposed to 5W30 make in
my car?
 
Thanks in advance.
