It's been explained to me that these days the new cars are requiring a 5W30 or
a 10W30, and I think some might even require a 5W20, but I don't know which
cars those are. My question is, are the older guidelines for single grade oils
pretty much the same: sae 30 for temperatures around 40 or above- etc.? I
can't remember exactly what the temperature cut-off ranges are. I've got 5
gallons of sae 20W that I plan on using during the 2nd quarter of the year:
March - June. The two vehicles that I currently have are a '93 GMC Safari Van,
and an '03 Chevy S10. Also, I have a bunch of 10W40 which I guess I can use
during the hottest months- at least in the van.
I'm very interested in hearing all about this stuff from those of you who have
