i had my local NAPA order a couple of cases(i'm good friends with the manager) and he keeps like 3 cases in stock. it cost right around $3 a quart. and, this one will make you read this twice, it's green. the oil is green. that might not be wierd if you've been around it, but when i first saw that, i had to read the bottle again to make sure i had the right stuff.
