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 bought a 1989 F250 brand new... 35 years ago... WE have had Unleaded 85% since the day i bought it....... Every tractor, mower, chainsaw, car, truck i have has been burning that for over 35 years. ------------- Like them all, but love the "B"s. |

| 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.
