Morn'n Folks, I just bought a WD45 and want to know what kind of gas/additives should I use given that regular leaded gas is not available? Thanx, Dan

I use no ethanol premium unledead in all of my gas tractors and small engines along with stabil if they will sit for awhile. Haven't had any issues.

I've burned unleaded 87 in my WD and 45 for as long as it's been around. 40 yrs? Have had no problems. Worst case scenario is pull head and put hardened seats in. I say don't worry about it.

I've been told that a WD45 already had hardened valve seats and to run unleaded gas.
unleaded goes in all our old tractors with no lead additives used.

X2 If I were planning to run my old tractors enough to keep the fuel rotated frequently then I would use the cheaper unleaded with ethanol in it but I would be careful to make certain to get all of the ethanol out of the entire system before parking it for the winter.

Non-ethanol for me! It's fine as long as it keeps moving through the system. If it sits for awhile it's going to draw moister and that causes problems.

everything around here (with no license plate) runs strictly on non ethanol these days. Really helped reduce issues. I have not had any luck with additives.

Now that I am retired I don't drive my pickup enough to keep the ethanol fuel rotated through it so even though it is licensed it only gets non-ethanol. My Wife's car has become our primary transportation and gets driven at least once a week so I use the cheaper ethanol fuel in it.

i sure dont understand the problwm with ethanol fuel... I fill the truck every 6 weeks as we dont use it much.. Wifes car is every couple weeks... 4-5 small tractors that only cut grass in the summer and leave a gallon or so in each for 4 months at a time, and never had a problem..

Last Spring I was at a friend's house; he was trying to get his Ford Bronco running after it sat all winter. The carburetor was full of what I call "Donkey Snot" from the ethanol. He took the carb to a mechanic to get it fixed. A couple of weeks later we chanced to meet up at the local gas station where I was pumping premium non-ethanol gas into my 1985 F-150 and he made a snide comment about how he couldn't afford to buy that expensive gas...

I have logged just about 1 million miles on 7 Ford pickups since 1982. Zero problems. Same goes for about 10 other cars and minivans. Zero trouble. I have 12 years of tractor rides and some plowing demonstrations on my WD-45 with nothing but ethanol fuel. When it gets put away for the winter, I shut off the sediment bowl and let it run dry. The tractor sits for 6 months with a 1/2 tank or more of ethanol and never once in 12 years have I had any issues. Engine probably gets 50 to 60 hrs per year on it. My One-Seventy high deck tractor uses ethanol for the last 5 years. No problems. Same fuel used in my D-10 and no problems. The only thing I won't use ethanol in is my lawn mower.

. If you use a motor every day or week you can pour whatever witchcraft ethanol you want into it. But if the engine sits, like that prized restoration tractor or car or pickup or snowblower or lawnmower sitting for months off season, avoid all ethanol. Splurge on recfuel recreation fuel and you won't need to fiddle trying to fix the carb every time. https://youtu.be/iWL7p0Pnb8Yhttps://youtube.com/shorts/EywwG906JMIhttps://youtu.be/TQZK-hcl5M4 My father's favorite utility tractor, a Ferguson 35, sat for twelve years after he passed. I was able to get it started with the fuel in the tank since he put non ethanol in it. I left ethanol in a push mower five years and it rotted out the carb bowl and leaked all the fuel (probably saved it). Fuel conditioners just take your money. Don't believe them. Be really careful out there, we put a huge amount of work into restoring these machines so choose fuel so they can farm and feed the next generation. .

Around these parts, the non-ethanol 87 octane is priced 50-55 cents per gallon higher than the 87 octane ‘regular unleaded’, what have you guys noticed for a price difference?

I tried to follow the science, but it was not there. I then followed the money, and that’s where I found the science.

Lars, the non-ethanol penalty around here varies from 10-40 cents a gallon at the station I use. I watch prices, when they are down I stock up.

there is no gas station within 50 miles of me that sell non-ethanol... thats all we got for EVERYTHING..
Seems like some people or areas of the country have problems with the ethanol if it sets for a few weeks... Others have no problem with it setting 4-5 months at a time.. Maybe its the humidity or temp changes. I have not had a "carburetor crud" problem with it setting for 4 months.
