Amoco, now part of BP, has always sold unleaded gasoline. Their premium gasoline has NEVER had lead. Read the story at the link. Forget about additives.

It's not a problem... some of us just get a little wound up answering duplicate questions... LOL

Too many snake oils out there that do nothing more than empty your wallet!

The regular gas at the pump will serve nice we have been using the 10% blend for 25yrs now and no problems ETHANOL just works

Don: Lead was only ever a benefit to HIGH PERFORMANCE, HIGH RPM engines, your Farmalls are neither. When non leaded gas became the only choice I was running Farmalls 300, 130 and Super A. The 300 was running 800 to 1,000 hours per year, most of it overloaded. The SA and 130 were each burning 500 imp gallons of gasoline per year. Let me assure you, the bottom end of those engines will require rebuilding long before factory original valves, even on no lead gas. In fact I have put new piston and sleeve kits in without doing the head.

Society today are addicted to additives, especially when it comes to a vehicle with an engine. You walk in most auto parts stores and it's truly unbelievable the amount of shelf space devoted to additives. It must be a good money maker for the stores, because most of it is not worth a tinkers damn.

Lead in fuel did not and will not help sticking valves.

Lead deposits used to collect on the seats and sealing surfaces of the valves, providing a "cushion" so they didn't hammer themselves apart.

Hardened valves and seats have eliminated that problem.

I had a problem with my SA a few years ago after it got warmed up & was working hard mowing, wide open in 3rd with a Woods L59 belly mower. After about 5 minutes it would start crapping out & loosing power. When it cooled off, it ran fine, but again once it got to operating temps, it started missing & running rough. I figured out it was sticking valves when hot, so took the head off, removed all the valves, cleaned up the stems best I could and started using a lead "substitute". That actually seemed to eliminate the sticking valves problem, but I eventually overhauled the head and engine anyway, so don't use it anymore.

The only thing that lead stuff is good for it to waste your $$. It doesn't really do any thing for the gas/engine and only makes the company that sells it stay in business. Its as worhtless as putting a bandede on a bullet hole

No The amount of lead that is in these snake oil products one could not even wright his name with . Use a good quality gas use the correct oil and run it.

Not over on this side of the board too often but here I am-

Don't waste your money. Also, by now most engines have been rebuilt since they got rid of lead in the gas so they should've had hardened valve seats installed, possibly with the option of LP engine valves because they hold up better to the gas w/out lead in it.

Several discussions a year on this subject... always comes out with "save your money, doesn't help."

Been running a lot of old tractors hard for many years and never had any trouble related to valves or fuel. We use regular unleaded... my father in law uses ethanol and has no trouble either.

Don: Your really not the problem, my apologies if I offended you. There are a few subjects discussed here that don't lend themselves very well to the archive system. Everyone have their own unique way of putting a title on a subject. I guess we'll never find a computer that out thinks man.

I've been using regular unleaded now for three years in my H with no problems. By buying a lead additive would only raise your price per gallon. We all no we dont need that. My advice is dont waist your money. Good Luck.
