Maybe this has been discussed before

Postby BKERR » Mon Aug 12, 2019 1:17 pm

But I could not find where to look. So excuse me ahead for this question. I am old enough to remember when we did not have unleaded gas let alone the junk that is in the fuel today. How does this effect the 154 from about '65 that I am restoring? Should I add a lead additive to the fuel? What about valve seats? Is regular unleaded okay to run?

Thanks in advance

Bob

It is okay with the newer gasoline.
There are two ways to get enough Cubs. One is to continue to accumulate more and more. The other is to desire less.

10% ethanol blend will work fine in your tractor. No lead additives needed.
I have an excuse. CRS.

Really? Try a search for "unleaded gas".

Bob, use the Search window in the upper right corner of your screen. I got search results from entering ethanol, "lead additive", and "unleaded gas". Use quotation marks if more than one word is being searched.

FYI: If you do a Google search for "Farmall Cub unleaded gas" or anything with "Farmall Cub" in the search query, one of the first hits you'll find is at our forum site.

Hope this helps.

I've been wondering about this for a while. I eventually went to pure gas N/A with some additive. I think it has something to do with the engine design. These are flat head-valve in block so the unleaded must be fair fresh or treated to prevent , basically water.
It isn't like the valve seats are going to drop out.
