I am still old school i guess and do all my own maintenance on all my vehicles, I have seen the absolute airheads that are employed at my local dealers and oil change places and I personally dont trust them to touch my vehicles.
Buy Mobil 1 Supercar Advanced Full Synthetic Motor Oil 0W-40, 1 Quart at Walmart.com

This is what I use. Sometimes my local costco has it in stock in their warehouse.. but my local walmart always has it as does amazon. You can save a few pennies with the 6- packs.
Search the threads in the forum. There’s quite a few oil threads if I remember. @AXE has some good oil analysis done too and has managed to get his oil changes down to $50 or something like that.
