The question is can I use 100 % BioDiesel in a 2002 7.3? What are the problems/ risks if any or mods needed to run this fuel in New England for the summertime? Would running a mixure of 20% bio w/ 80 % diesel be better?
I recently found a supplier near by and was wondering if I could run this fuel.

Any input or information is greatly appreciated.

 

I wouldn't suspect any problem in the summer...I run B5 year round and it gets sub-zero here. Runs like a champ...if I could get B100 here I'd run it in the summer.

Get yourself some extra fuel filters and get ready to change them often at first...if your fuel tank/lines has crud in it, biodiesel will loosen it up for sure.

 

B100 will scour the inside of the tank & lines...
change your filters early, change them often..
kinda like voting in Chicago...

 

no reason you can"t run B100 bio......just keep some spare fuel filters in the toolbox, it will loosen up any extra crap in the tank

 

I run straight VO, but it dont go through that filter. But all above is correct for sure. when you first switch, have the filters on hand, but after you have been running Bio for a few tanks (filter change). you would only have to change the filter like any other fuel, cause your system will be "CLEAN".
Have fun burnin BIO

 

As mentioned above, Bio has solvent characteristics so it will clean out your tank and lines. Having a spare filter handy is a good idea, although I never needed one. I've run B99 in my 02 several times with no issues.

Just remember the B100 will start to gel in the low 40's, so as fall approaches start thinning it out with regular diesel.

 

Hey thanks for all those replies. I am sure to try it out soon. I will also keep a few extra filters handy and probably replace the first one after the first or second tank, then less often.

 

Yes you can and you should. The benefits of running biodiesel, even at low %'s mixed with #2 are well worth it.

I try hard to run some % of bio in my truck at all times just for the lubricity of bio. The only alternative fuel station I know of around sells BioWillie B99.9% and I really like the way my truck runs (and smells) on bio but it's sometimes a chore to drive the 17 miles to the station. At over $5/gallon it's only cost effective because I know I am prolonging the life of my engine.

I run B100 in mine as well and do not have any problems. My previous truck (Duramax) did not like it nearly as much as this Ford does.

I meet the fuel tanker from bentley biofuels, and he fills my 6 55 gallon drums full of B100, then I just store it in my driveway as I use it.

Very soon to get another load. With the prices rising so fast, I am considering getting 600 gallons this time.

I run only a 5% bio blend because its the most i can find. I would love to try 100 bio. The only thing i have to mention is i've heard that bio more than 10% will ruin(cause leaking) the o rings in our trucks, any truth to this assumption? Think i read it in a ford owners manual.

 

You hope. You don't know. Nobody has proved it yet beyond reasonable doubt.

 

CYA. This is so that if you have a fuel problem because of a bad batch of bio they can deny your warranty. I don't think it can cause leaking in the o-rings from dissolving the seals. Now, because of ULSD having less sulfur, it might cause the O-rings to shrink because the fuel is sucking out the sulfur that was sucked into the O-rings from the LSD fuel.

 

True, but old Rudolph originally designed his engine to run on vegetable oil so the concept is as old as the motor.

This is also true for dino diesel. If bad fuel causes a failure it's not covered. For Bio try to find a manufacturer that is meeting the current ASTM standards, and a distributor that is moving enough product to keep it from going bad. For Dino, I'd stay away from the places that look like they don't sell much diesel. The old rule of thumb is diesel should be used within 6 months.

 

I think it has changed so much over the years that Rudolph's using vegetable oil idea is probably not really much more than historical fact at this time. Metal and machining has improved vastly since then.

 

Can't argue with that, or the fact that there are all types of rubber type seals & fittings, computers, etc. that weren't there originally. I was referring more to the use of vegetable oil being used in the compression / ignition process.
