Well we do not need to discuss anything less than 5 micron because those particles can be in diesel fuel at you local station, and will get by your filter on the truck and right into the injectors any way.
As far as meant to be burned, it is not, but nither was peanut oil back when Rudolf Diesel developed the first diesel engine to run off of it.
New injectors wont be in my future, I might have to replace some wear parts inside the injector but i doubt it will be from the WMO.
Wvo needs to be heated because it is alto thicker than WMO, and the reason "People running WVO and other things have issues with injectors" is because they shut the truck down on a WVO mix and in gums up the inside of the injector as is cools and sits in there. WMO will not do this.
Yes the injection system is more tolerant than others, but there is a 01 vp44 powered dodge right down the block that has been running a mixture of WMO for longer than i have with no ill effects, We both have lift pumps so there is no problem there and i have a fuel pressure gauge.
Running WMO will not work for every one but it will work for some. I will continue to run it and if i have any problems i will report back to this thread.
BTW I was, and still am, running 100% WVO in my 86' 6.9l for 2 years with out issue, I just start it and shut it down on #2 and all has been well.
Thanks, Matt$.02
