I don't know for sure if the oil makes much difference, but why take the
chance? I found Ingersoll Rand synthetic oil at a local tool supplier for
$7.00 a quart. Sounds like a lot, but since my 7 HP 80 gallon 2 stage unit
uses 2 quarts, $14 wasn't that bad. Seemed like cheap "insurance" to me.

I'm surprised you can't find them in the hardware store ... I'd pick one up
on eBay.

Should probably be drained & replaced.

A big compressor is still on my wish list; but my little "2.5hp" (which in
reality is closer to 1 hp) seems happier with synthetic motor oil. Since
it's only air leaking past the rings, I don't think choice of oil is as
critical as it might be for a car motor.
