Farmall H gasoline additive

It became a second tractor with the purchase of a 560D then 3rd with a 656D, 4th with a new 1066. There is a guy down the road from me restoring his dad's 300 bought new in 1955 to cash crop 500 acres along with 1 smaller tractor. Some of these tractors did get used a lot more than others. There was a good reason for some of the 1950s and 60s gassers not to have seen a lot of use. The diesels that followed were much more fuel efficient. It quite frankly surprises me to see 56 and 66 series diesels around with as little as 5,000 to 10,000 hours on them. Someone obviously had little to do with them. Probably part of the reason North American farmer were always crying hard up. You will always make more profit when underpowered than overpowered.

A side-effect of the lead, used to raise octane, WAS reduced valve seat wear.

Dad & I farmed with 4-5 gas tractors, never did any additives since '74, and still have most of them. They were the main tractors, lots of work on them.

Perhaps the valve seats will wear a tiny bit faster, but the additives over time cost way more than a valve job, and since they aren't lead, are closer to snake oil.....
