5 quarts of G-oil free.
G-oil is a biodegradable, full synthetic engine oil made from 100% American plant and animal stocks. It is also non toxic and biodegradable (don't worry, it won't break down in your engine). I know, scary, right. I did some reading on it on Bob is the Oil Guy and it seems to test really well and is considered of very high quality. I am running it in the Tacoma just for fun and will send off a sample to Blackstone after 5000 miles. Anyway, 5 quarts, free with mail in rebate from Walmart.
