They finally made a 15w40 synthetic that wasn't some boutique oil like amsoil or schaeffers. When did this ADF 600 come out? Is that just chevrons part number?
I just go to Walmart and get mobile delvac, or delo 400 but my truck is older. The chevron went up in price by like $4/gal more so I use delvac now the last few years
