I would like to start changing my own oil after having some issues with the dealership. My question is where do you guys buy your oil. I currently use Castrol synthetic.
Thanks

pep boys mostly but sometimes autozone...that brand is usally in stock that you use....I like royal purple but its more $$$ and better imo

I don't want to be part of the oil wars, so I will just say I buy my oil wherever has a good deal (or I happen to be). this includes walmart, pep-boys, o'reilly, advance, or autozone.
go with a good filter (not fram)

Walmart

Autozone, or advance auto, whichever one has a sale. The 5qt jugs..with a good filter. Pour left over oil into a 1 qt bottle.. and return used oil in oil container back to them.
