Do these older farmall have to have leaded fuel used in them or are the unleaded fuels ok to use? Thanks

The only way that the unleaded gas "might" give any problems was if you were take this tractor out and work it day in and day out, pulling it hard for 8-12 hours straight, then you "might" notice a differance, is it probable, not likely. I would try to stay away from gasahol fuel, it is kinda hard on the little rubber peices and parts. most of the 87 octane fuel you buy around here will be pure fuel with no alchohal in it.

Quite the opposite, ethanol fuel is not hard on rubber parts, it will not do any damage at all. I use it in everything I own, and have been for at least 20 years now. I have never had even one little problem. Where do some of you people get your information?

As everyone else had already said, unleaded fuel is alright to run. There are lead substitutes out there at auto and tractor supply stores that you can get and use, but that is up to you. Good Luck.

I use lead substitute in my Farmall A and it runs much better with it than with unleaded gas.

If you do elect for a lead substitute, the old saying 'a little is good, a lot is better' does not apply.

Strictly follow the instructions on the bottle or you will be fouling plugs.

As others have said, it's not necessary.

skippy: I have a couple of tractors, been going close to 30 years on regular unleaded gas. The lead was only ever an issue with high performance, high rpm engines. These old Farmalls turning under 2,000 rpm will require engine rebuild, not related to gas or lead, long before valves give trouble.

Unleaded regular is ok.With the low compression of these "non-high-performance" engines,Mexican fuel could probably be used.As for no lead,the low RPM of a tractor engine isnt going to harm the valves (at least anymore than the previous 50 years of use has already done).The high lead content of old fuel has caked large amounts of lead deposits on the valves where they sit to this day...that still helps the valves years after leaded fuel was discontinued.When a rebuild is needed,insist on hardened seats/valves.

No one has leaded fuel anymore, other than at the airports. Or thats the way it is here.

100 low lead is not what blows the hipo engine, the builder and the driver is the cause. 100 low lead just helps to get it to that point a little quicker.

THE DAMAGE WAS DONE TO VALVES AND PISTONS.NOT FROM DRIVER.I PRELOADED A LOAD OF 100LL FOR DAY SHIFT TO TAKE AND MIX TOLUENE INTO TO DELIVER TO A COMPANY THAT SELLS IT AS RACING FUEL. NOT SURE WHAT THE MIX RATIO IS BUT THEY VERIFIED STRAIGHT 100LL CAN DAMAGE VALVES&PISTON TOPS.THE OLD 100/130 WOULDN"T

Unleaded 87 regular. I run that in my Cub and C. I think they can even run on lower octane than that.

There is a problem with methanol (an alcohol) when used in gasoline. Methanol will eat plastics and rubber/synthetics in gaskets and paint!!! Because this type of alcohol is rough on systems, it is not used anymore to my knoledge. Ethanol is the type used in gasoline today (plain old grain alcohol that one can drink in its beverage form). this is no problem, and has the side bennefit of assisting in the removal of water from fuel systems, and the near total elimination of deposits on plugs and combustion chambers. There is also some MTBE doped fuel (stands for Methyl tertiary Butyl Ether) the Methyl group in this relitively nasty stuff causes similar problems to methyl alcohol. Last item, dry gas, or other fuel line antifreezes are often Methyl Alcohol. Do not use them as they are hard on the plastics (as noted above) and redundant for H2O in the gas.
Hope this helps.
