I just bought oil for 6.44 per qt and 4.60 for the oil filter at Rockauto. Shipping was 11.99 but this is the least I’ve spent on an oil change on this beast. If you’ve never done your own oil change I would recommend replacing the oil pan drain bolt. The stock one is a pain the ass to remove. The head on it is almost flush. I like this one for LS3 engines with a magnetic tip C6 Corvette LS2 LS3 LS7 Magnetic Oil Drain Plug NEO Magnet Fits: All 05 through 13 Corvettes https://a.co/d/hoKa4hS
