Upon recommendation from a crusty old Harley mechanic, I've been putting a capful to 1 ounce in a full tank of gas for 20 years in mine.

B, I sure would not mess with any high octane fuel. That engine has a compression ratio of 6.2/1. Just barely enough to make 85 or 87 octane fire off.
Lead was useful to lubricate valve seats, not valve guides.
When it was rebuilt in the 80s, it probably got hardened seats.
I tore down my 8N and rebuilt it in the garage in the mid eighties. It has hardened seats. And it has run thousands of hours since pulling a plow, disc, corrugator, terracing blade, and fresno. It runs as well today, as it did with the fresh rebuild, all on 87 octane, no lead, 5% ethanol.
Have you taken the fuel cap off and seen the fuel boiling inside the tank from engine heat yet? That is when you know you have been working the old girl.
One cousin has the Furguson OHV twin to the 8N, a TO 20. Grandad had three 8Ns, an Uncle has three more, my Dad had one. They all get fed the same diet as mine. They all have spent 50 years working in the fields, and none have failed prematurely.
Don't sweat the fuel. She will run well on whatever you have available to feed her. And with your rate of usage, she will still be running when your grandkids die of old age.

The seat is what suffered at the loss of leaded gas, not the guide. But the loss of lead in gas wasn't normally a problem for most industrial type engines as they had hardened valve sets already. Not just Ford, but Deere, Continental, Perkins, etc. etc. Many even had valve rotators that turned the valve a partial revolution each time it opened, keeping the seats free of carbon. This more likely to be seen in OHV engines.
This aside, Marvel is still a great fuel additive IMO. I started using it in older Harleys that didn't yet have hardened seats, at the urge of an older fellow I once bought a motor cycle from. He told me to just use a cap or 2 full per tank & not to use it every tankful, just every other one. Said it was so good, that it built up in the system & if used too often, the engine would begin to puff smoke. He said you can plainly see when you've used it too often. I thought, BS! It was not BS.
I don't need it to lube seats in anything I now own but have found another use for it. I winterize fuel systems with Marvel. Way better results for me than Stabil.

Marvel also works well as a fogging agent when putting marine engines away for six or eight months.

My guess is, you’ve got hardened seats, and you’ll be fine, but with as little as you’re using it, lead substitute would be cheap.
OTOH, any motor with a flat tappet cam ought to be using a ZDDP substitute these days. Manufacturers have taken much of the zinc out of motor oils (ruins catalytic convertors, and isn’t needed for roller tappet cams and OHV motors). Even lawnmowers/garden tractors ought to get an SJ oil or ZDDP substitute (the zinc is way low in newer SN oils).

But ethanol free gas is still not leaded gas, is it? no

I have two 8Ns, one my Granddad had rebuilt in 1983 with hardened seats and I just use non-ethanol gas. The other I mix Red Line or Motor Medic lead additive into non-ethanol gas that was recommended by the N Tractor Club and N-News. http://www.ntractorclub.com/ https://n-news.com/

It's actually to lubricate the valve seats and to prevent engine knock.
You can use a lead sustitute to take care of the problem. This. It is the valve seats that require the lead additive. You can have hardened seats installed to prevent the wear.

I run mostly ATF in my diesel fuel to boost cetane. I also use Marvel Mystery Oil as a fuel additive alternately.

Doesn't the station in Hickville have leaded gas?
There's hardly any place to buy leaded gas around here. One station about 30 miles away has it. Our local Chevrolet dealer has a performance shop. He sells 2 grades of leaded gas. One is 100 octane and the other is 110 octane. It comes in 5 gallon cans. Another option would be 100 LL (low lead) at your local airport. kwg

Get you a lead substitute for the gas, and Rislone makes an oil additive with ZDDP. ZDDP was used by my neighbor on one of his motors for the valve seats. Normally its for the cam and lifters. Maybe that's what it was for, and I misremember.

Zinc additives..ZDDP
and then if one puts about 5% diesel fuel mixed in with your gas, it increases your octane...

That'll work real good.. spendy, but I use that in my lawn mowers and Trimmers around the house... Figure in the frustration of having to clean out carburetors, and replacing spark plugs etc, avoiding all of that, paying $4.50 a gallon for avgas doesn't seem like that bad of an idea any more...

I run mostly ATF in my diesel fuel to boost cetane. I also use Marvel Mystery Oil as a fuel additive alternately. I've been told that ATF can screw up injectors in diesel and gasoline engines. For 16 years I've been using a mixture of Power Service (to increase the cetane/clean injectors) and TWC3 2 cycle oil (to lubricate the injector pump and injectors). Every time I fill up I add 7/10 of an ounce of the mixture for every gallon of diesel. I used a MMO/Power Service mix for about a year until I found out that 2 cycle oil is a much better lubricant than MMO. MMO is almost all mineral oil with just a few other additives, it does smell good though..

I use MMO in everything. I've been known to even mix it with my coke. A splash here and there has saved me countless hours in carb rebuilds alone. Nothing gets stored for the winter without some MMO being ran through it.

Everything I've found discussing this discredits it.
