I'm told the valves will burn without an additive. My old Farmall M seems to run just fine on unleaded - for about ten years now. If needed, what do I use?
Thanks.

I've been running my 1966 250 for 11 years on regular unleaded, and have not had any valve problems yet.
Some people use Marvel Mystery Oil in their fuel tank as a upper cylinder lubricant. I'm sure that you will get more replies on this topic. | | | | | Joined: Feb 2005 Posts: 355 Member | | Member Joined: Feb 2005 Posts: 355 | I had the same question Rich. Here is what the guys had to say on this subject . . . http://www.stovebolt.com/bboard/cgi-bin//ultimatebb.cgi?ubb=get_topic;f=22;t=002579#000000 | | | | | Joined: Dec 2003 Posts: 2,953 'Bolter | | 'Bolter Joined: Dec 2003 Posts: 2,953 | Been driving the 49 for about 15 years on unleaded with a 1956 235". Have not touched the valves or seats yet. Only do about 3000 miles a year however.
At one time I was concerned about this and met ths old gentleman who seemed quite knowledgable on the topic and he told me that he put in a cup of ATF in the tank each time he filled it up. I tried it but thinking a cup would be good, a quart would be better. Not! The truck shook, smoked, popped and ran terribly until I ran the gas thru. So I don't know if the ATF would help or not but I have not done that trick for a long time. And as was written above, if you are not driving at sustained high speeds I would not worry about it.
