has anybody bought veg oil from costco? This might well sound like a daft question, but I'm a veggie oil virgin and want to make sure I don't put the wrong stuff in.
I've been using the KTC stuff both in it's supermarket clean form and used by a Thai restaurant form with no ill effects in my 2.5TD for a year.
I mix it between 50% derv in winter to almost 100% veg in summer.
