I am about to hit my 25k mark at which point I will be doing my own oil changes. Just did my first home oil change on our 2011 Highlander today....stupid oil filter element style.
With this said, what oil should I use? Is it a good time to switch to full synthetic? I am assuming the dealership used conventional 5w30, correct?
Also, how much oil is needed? I see it calls for 5 quarts, but wouldn't I need more since I also have the oil cooler?
Last question - oil filter. Which oil filter do you use? Fram? Bosch? Napa? Something cool I don't know about?
