Is this leaded 110? Not exactly the best fuel for the more advanced exhaust feedback control fuel injection. BUT it will still work- I did some work with a trophy truck team in the early 00’s and they used leaded fuel with my WB sensors. After about a race worth’s of testing, they still worked ok. But over time, the lead will hurt the sensors.
That being said, higher octane basically increases the safety margin for high compression, high loaded engines. Timing problems? Octane. Fuel problems? Octane. Temp problems? Octane. etc…
Of course, they don’t fix the problems, but they help reduce the normal resulting knock problems.
I searched Sunoco 110 race gas and noticed that the sales commercials indicated that 5 gallons was going for almost $100 or $20/gal. ouch
I pay about $15/gal for VP110 to keep the Outlaw Bug running. In reality old style engines with high compression, need lead and high octane to survive. Luckily for me I can get it about 45 minutes away. At least at that price its purple in color. LOL
For the old modified pinto powered FC cars, I only needed about 100 octane. I usually bought it at rural airports with a credit card and using a N number from something resting nearby. YMMV
When I was a kid, my dad would warm up the car in the garage with the overhead door open. I loved the sweet smell of leaded gas exhaust as I stood in the vapor fog while it warmed up.

I run 100ll in my Formula Ford. I use NCC-1701 for the tail number when I buy it.
