The Stovebolt Site Forums The Parking Lot Big Bolts what fuel to run in my loadmaster?

im waiting on delivery of my orig 20,000.00 mile loadmaster, can i run reg unleaded gas in it without harm??? or do i need to run an additive?? want her to run good for along time...

Depends on how much and how hard you'll be using her.If your intention is to occasionally idle around empty, to the tune of, say, 2,000 miles a year in flat country, the regular will be fine forever. If, however, you'll be pulling steep grades with a full load of topsoil, the engine's internal temps will be substantially higher. That being the case, I'd run, like, 90 octane and a lead substitute to help keep the valves lubed and cooler at the seats.

prob be around 100 miles per week empty, poss once and awhile trip 20 miles to town then poss afew small loads, where can i get lead additives?

There is no substitute for tetra-ethyl lead. The "instead of lead" additives are a waste of money. They do not have the same valve lubricating properties as lead...because they do not contain tetra-ethyl lead.

Personally I would not worry about it in a truck that you will just be tooling around in.

The only real solution to the unleaded gas question is to have hardened valve seats installed in your head.
