Ethanol free is probably even more important, this is great advice! But in terms of oil; do what you're comfortable with. For me I've stuck to the dinosaur stuff as that's what it's run for 40 years; everything else in my garage is on synthetic.
I’ve just ordered some new tires, going to pull the wheels off my car and get them mounted. Did you find a place? I may just see if Costco will do it? I’m also in the East.
