I like the idea of a bag instead of the plastic jugs, so here I am.
I bought a 12 quart bag in a box of Super Tech today for $30.
At $2.50 a quart the price is hard to beat, plus they say ST FS oil is just about as good an oil as you're going to find in a non brand name oil.
3 DIY OCIs for $30 + tax and the price of oil filters.
