When these tractors were new they were running on leaded gas, I'd assume. So what do you pour in the tank now? A lead addative?

Mike: These old Farmalls never did need lead or high octain gas. Those features were designed for high performance, high rpm engines and your Farmall is neither.

I've been running unleaded gas in Farmalls, now close to 40 years. I've probably had rebuilds done on 10 of these engines and all of them needed piston and sleeve kit long before head and valves gave trouble. My dad bought a Farmall 300 new, I do not have it currently but do know it's on the 6th set of pistons and sleeves. It was rebuilt roughly every 4,000 to 5,000 hours. I do remember on a couple of those rebuilds the head required little or no work. I can say much the same for my Farmalls Super A and 130.

Lead additives are a waste.

Run regular 87 or even 85 octane fuel in your H. The compression is so low that high octane fuel will be nothing but a waste of money.

I run Mobil Delvac1 5w-40 in my H. 75 psi oil pressure all day long at anything above idle speed. Hot low idle it drops to 50 psi.

Pull the oil pan off any tractor you buy - if there is sludge, clean it out as best you can. Then run modern oil in it.

As for the oil filter doing nothing - I believe it started on the H's and M's that full pressure lubrication went mostly through the filter. I know this much for sure: if you leave the filter loose it will pump the oil out in a matter of a few seconds (don't ask).

Well, no. They were made to run on kerosene or distilate.They just used gas to warm them up enough to but the kerosene. Over the years. gas became the standard,but these could be orderd to run on straight gas.

I use gasohol in my cars and truck but not in my tractors. I use gas without alcohol in my tractors because the alcohol can evaporate if you don't use the tractor for while like over winter and all you have left is some low octane gasoline.

When I go to the parts house to buy a new oil filter, they make a big deal pulling out non-detergent oil. I've seen it on forums and in mags but I could not think through the reason.

Parts house guys are in the business of selling parts. Parhaps they want to sell you more?

HI MIKE, ITS THE VALVES that you have to worry about. If your head has been done in the last say 25 years it will have the new hardened seats and new guides and you should not have to worry about the gas. At lease thats what I was told + these tractors do not use valve seals like a car unless you put them on your self and that will help also. As far as oil the filtering system on an H is terible. Someone with more knowledge than me can say for sure but I believe only about a few cups of oil a day actually go through the filter. so its like a bandade its there but does not do much,LOL I use straight 30 HD in most all my tractors and I am using 15/40 in my new super duper H motor. If you use it make sure its for gas motors and not specifically diesles. There is a difference I do not know what but my neighbor swears that you should use it in anything that takes oil. I dont know about a new vehicle that says 5w but he does not own anything newer than a 1980 anyhooo. JON

you can use diesel oil in a gas engine, but not gas engine oil in a diesel.

Once in awhile I"ll put an ounce or two of Marvel Mystery oil in with the gas for a little extra lubrication. Seems to help for warm starts but that could be all in my head.

Naah, just regular unleaded gas. Those "lead aditives" don't contain lead anyway and are pretty much a waste of money.

I'll second that motion. Regular un-leaded or E-10, whichever is less expensive. Those 60+ year old Farmalls don't much care.

My 1968 IH seems to like the higher octane gas a bit better though.

According to the Tractor Vet, premium gasoline is what was recommended for that era of tractor, especially if you work them hard.

Well, considering the amount of money I plan on throwing at this tractor to restore it, I don't mind putting the good stuff in the tank. He will deserve it, I'm sure.

Mike, use the high priced stuff if you want, it won't hurt anything, but ANY engine that was designed to run on low octane fuel will not benefit one little bit from use of high octane. You will just be throwing your money away. The exception would be if you made some serious compression and timing modifications to the engine, at which point that engine would no longer be what it was designed to be, and then the high octane fuel definately would be beneficial.

With the low compression of these older tractors, the finest gallon of 87 octane will do just fine...they have been running that way for years.

OK, then let me ask this. If you rebuild an engine to specs, why can't you use modern high detergent oil in it? My buddy, who's an over the top mechanic, says one of the reasons modern cars can rack up so many miles is the new oil we use. Why wouldn't we get more hours out of our tractors with new oil?

No reason whatsoever.

As I understand it, the problem with using detergent oils in engines that have NOT been rebuilt is the sludge buildup that"s there. The detergents loosen up all that sludge and it starts circulating around in there.

Been there, done that with the detergent oil in engine with time on it. What happened was I changed the oil and put detergent oil it it. Then I was driving it around the field with a mower behind...I was not paying attention to the oil pressure...it locked up!!!!! When I took the pan off, the screen on the oil pump was full of sludge and blocked it!!!! It cleaned the engine up good...but the sludge had to go somewhere...

Nebraska Cowman has it right, you can even use the modern synthetic oils if you want to pay the price. If there is such a thing as not believing everything in the original owners manuals, the recommended lubricants would be one of those things. You need to understand that when IH built those tractors 60+ years ago, they DID RECOMMEND using the best oil possible. If that same tractor were still being built today, the recommended oil would most likely be a multi-weight and possibly even a synthetic.

You CAN use modern high detergent oil in your old tractor. Most of us do and have for years. There are many reasons modern engines last longer including tighter tolerences, better filtration and dirt exclusion, more eficient and complete combustion. etc.

I think the #1 reason new engines last so long is OVERDRIVE. They don"t have to turn the RPM"s they used to.

The newer oils do work well in older tractors. why would you think they didn't ?
