Here are some scans from the label of 'ACCEL' SAE 10W-40 API-SF automotive
engine oil rated for model years 1988 and earlier:

I just bought a bunch of quart bottles from the local Wally-World at
under $2 per qt.
Prices may vary at other stores. I have not tried the oil yet, but
it will be the refill at
my next Oil change this spring.
