Re: A good reason to run B100 over SVO
[ QUOTE ]
The IDI 6.9 is very tolerant of fuel quality. I joke with people saying that my truck could run on boiled horse pee and not know the difference.
WVO can kill the IP on the 6.9 IDI engine if it's run too cold, I have heard of instances of poorly warmed WVO causing the input shaft on the IP to snap due to excessive shaft stress.

And this is something people need to look at when doing WVO, Not all engines are made the same and tolerate the same fuels. An IDI can be abused fuel wise much more than a high pressure fuel system IMO, and it doesn't even have to be a 6.9l or a 7.3 IDI. Just between my father's IDI jetta and my 6.9l you could see the difference just in start ups, the 6.9 after a few cranks would start on WVO but the Jetta would need several sessions to start (and he has a 12v pump to help prime the system too). But the bottom of the quote shows that you cant push them to the breaking point and expect them to run flawlessly.
Because of this I went to running straight Bio today as a matter of fact. Thinner which makes it easier on the IP, more combustable, and supposedly easier on injectors and valves but I think that all has to do with heat pertaining to WVO.
