As a retired mechanic, I still change my own oil. I always used Mobil 1 but with price increases I'm going with a cheaper synthetic.
I bought two 5qt containers of Kirkland synthetic oil at Costco for $30, $3 a qt! My GMC truck takes 8 qts, so that's about a $35 oil and filter change for me. My wife's car only takes 5 qts.
