...I have 44 yeere's worth of experience operating, servicing and repairing forklifts...5 propane units inside the packing hosue/cold storage...3 Diesel JD Industrial units out in the field...
...inside use or periodic use...PROpane hands down :thumb:
...outside work in gravel or dirt, then JD Diesel Industrial models win there :thumb:
...we filled all of our own propane cylinders and one standard size tank can be filled easily in less than 2 minutes :thumb:
...as a side note relative to a previous post...Ethanol is not a problem whatsoever in gasoline blends and does no damage at all...
...however, if you have, or have previously had water, rust, varnish or poor quality fuel in your system...you may experience some unwanted effects due to the condition of the system PRIOR to using gasoline with Ethanol...
...contrary to conventional wisdom...this is NOT, nor ever has been the "fault" of modern day gasoline/Ethanol blends...FACT: it is 100% a system contamination/integrity issue, not an Ethanol issue
Ethanol is like most alcohols. It absorbs atmospheric water because it has a hydroxide ion.
Water will dissolve certain things (like metal) that gasoline or pure alcohol won't. Hence why alcohol in your fuel is a risk.
Ethanol is a crappy motor fuel. Use MTBE if you want to boost octane without lead. MTBE can't absorb water even if it wanted to. Not miscible.
I've run both ethanol mixes, toluene, and MTBE to achieve 100+ octane, and I can tell you that all things being the same, the MTBE is going to run faster at high compression.
Now for running ag or industrial equip, the HP isn't critical. But the water certainly is.
Biodiesel is good solution to renewable fuel. Ethanol is a step backwards.
