May be nothing but worried... please help

No big deal at all. Truck can run on Jet Fuel, #1, ULSD#1, and ULSD#2. Jet Fuel and #1 are the same just filtered a little more. DO NOT run #1 or Jet unless an emergency though wont hurt every rare once in a while.

 

I think when using Biodiesel and your filters plug, its not from the fuel being bad. It is from the fuel cleaning the dirt out of your tanks and lines.
I use bio as much as I can. Have no fuel problems.

 

When Rudolf Diesel showed his engine off to the world in Paris back in 1898, it ran on peanut oil. His intention was to have an engine that farmers could run on cheap, locally available fuels. In other words it was originally designed to run on biodiesel...so it isn't going to hurt it.

 

Thats actually only partially correct. New engines are designed to run on ULSD. Our company tried Bio for a short term and switched. Expensive and we were having issues with a new KW and decided it wasnt worth running a 150k dollar truck with something that wasnt designed to be used. I am in the fuel business here in Alaska so do have a bit of knowledge on this. Read my top post.

 

That isn't a problem with the engine, but rather the aftertreatments. Before EGR/DPF/SCR, you could run a truck on pretty much any combustible oily liquid...now it gums up the works if it's got too much soot/ash/particulates exiting the combustion chamber.

 

Good response. Exactly right. My brother in law in Nicaragua uses fry oil for his 1988 blue bird bus and zero problems.

 

Nobody is going to avoid biodiesel because the majority of the diesel comes off the rack (out of the fuel terminals where it is loaded which got at that location by pipeline) at 5% mixed--at least that is what the NOTES say on the Bills of Lading. The problem is when THAT is cut 20% and is advertised at 20%....

 

This is biogunch (~B20+) being unloaded in 80 degree weather. There is a reason diesel engine manufacturers recommend a max of B20 for use in their engines and it is supposed to be tested and rated to meet U.S. standards. It rarely is tested or rated by anybody resembling a reputable lab and when it comes out of the pump, it is NOT what the label claims it is.

 

You mean to tell me I can scoop a 5gallon bucket into that McDonalds kitchen french fryer at the end of day, pour that fluid into the tank and drive a 18 wheeler a while?

 

A very short while.
