Buy the highest octane (91 or 93) that you can from a busy national chain and don't worry.

If you want (and I do) use the Chevron Fuel System Cleaner BEFORE every oil change. Add to your full tank about 300-400 miles before your change, run it down, refill, and go get an oil change.

For winter storage, I use 1 ounce StaBil per 2.5 gallons fuel.

That's it.
