Fuel for TO-20

Now that Neal (thanks Neal!)has determined that I have a TO-20, I have another question. Obviously the engine was engineered to run on leaded gas. I'm running it on regular unleaded, and it runs fine. But regular unleaded is a lower octane than regular leaded. Would it be better in the long run to run it on unleaded premium? Would it also give me more power when I'm using an implement that requires more power?
Thanks!

Hi Rich

If tractor is rarely used and it takes few weeks
or few months to consume 1 tank it is preferable to use premium gas because gas loose performance with time. When tractor used for light work
I put premium gas only. If doing hard work like plowing I put 6 ounces of 2 stroke engine
oil/gas conditionner per tank it helps to lubricate valve guides and minimize valve self grinding on seats and will avoid varnish deposits
too.

Just my little op

Good tractoring

I have a TEA20 Ferguson and I always mix lead additive with the gasoline. Those old engines do not have hardened valves and are meant to run on leaded gas.

The antique car crowd has had this debate for years - lead or no lead. The consensus is that lead wasn't added until sometime in the 30's and that the old vehicles ran just fine without for many years. The lead was added ONLY to help prevent pinging as the engines got to have higher compression ratios. No low compression engines really need the lead. As a side effect, it also helped 'cushion' the valves somewhat for the faster revving engines to prevent them from pounding themselves against the head or block.

The old cars, Model T's, A's, Chevs, etc have proven themselves to run fine with the newer lead free gas. I know, I've been riding in or driving T's and A's for over 50 years.

The Fergy, being a slow speed, low compression engine will run just fine on unleaded too. Don't waste your money on the additive.

In my opinion, the answers are 1)nope; and 2) nope. If it runs fine, keep on doing what you're doing.

Ditto to that. In fact running premium, besides throwing your money away, might actually cause your valves to burn up. Use it and don't worry - it's just a motor like any other.

As a happy 1959- TO-35 owner,also as a machine shop owner here in Ohio: After rebuilding many Cont engines from Towmotors to tractors,(great products) all the cly.heads I have ever seen have hardened Exaust seats in the heads. Due to the nature of their work,this was great foresight of the engine manafactor. The use of unleaded gas has no effect on the life of your tractor engine. As noted before: todays gas loses alot of the octane thru the air in about 30-60 days.I use prem. on the last fillup of the season,it(TO-35) seems to run alot better after our long cold winters here. Also dont waste any money on additives, Also as a classic car collecter, I do add 6oz. 2 stroke oil to all my tanks after driving season is over.This is because it helps keep tanks rustfree. (have you ever seen a metal 2 cyle. mixing can rust out?)I have'nt. Some auto gas tanks are very pricey to find now.(Rustout) I hope this helps other Ferguson owners.
