higher octane fuel is only necessary if you have pinging. Meth injection is another alternative to high octane fuels...you do not need either

Lake Pleasant Pkwy in Peoria? I checked their website and they don't show 110 stuff. 5 gallon cans or direct delivery from the pump? I do have a high compression Italian car that doesn't like the premium unleaded 10% ethanol fuel here in Fountain Hills. Sure appreciate the tip. The only 110 leaded race gas I can get over this way is from Torco in Apache Junction. 5 gallon cans only.

yep I go up the 303 to Lake Pleasant parkway, go north a few miles to corner of Lake Pleasant Parkway and Carefree hwy, they have the 110 octain but the pumps have a lock on them.
they will sell to anyone... just need to go in and ask to unlock the pump and they will.
I fill a few gallons in a regular gas can and just add one gallon on top of a 9 gallon 91 octain fill.

110x1 + 91x9 ÷ 10= 93

And if you plan on storing (as in not using) the fuel for longer than 3-4 months. Premium blends have better antioxidants that allow the fuel to last 9 months or longer. (This info is from Sunoco.)

yup ^^^^

When I put it away in the winter in a warm dry garage I fill it up and add a bottle of Seafoam.

Same for tractors and other lawn equipment. SF is great for small engines when they get gunked up.

This came well recommended and I’ve never had an issue even though the only fuel I can get is E10
