BIODIESEL

Here is my question: Do I proceed w/biodiesel that I purchase at local gas stations or start buying bulk petro based diesel. I ask this after having a Ford CAV injection rebuilt to the tune of $500 and another Ford CAV cleaned to the tune $300.

I have a ford 4610 (mid 80's w/2000 hrs- 3 cyl diesel) and a 2910 ford (late 80's w/750 hrs- 3 cyl diesel ). A Case 580 E backhoe (Cummins diesel) and a Case 450 dozer (Case motor- diesel). I only run about 100-150 gals of diesel fuel a year through everything combined.

After paying to have both Ford CAV pumps worked on (both were gunked up w/brown sludge), my diesel injection shop said to stay clear of the biodiesel. They said that if you do not run the machines every 2 weeks you are asking for trouble. They showed me the brown gunk that came out of both pumps. After doing some research it is my understanding that the biodiesel is solvent cleaning the petro-diesel buildup out of the system. To date I have have not had any problems w/the Cummins or Case. Both Ford tanks are now cleaned out and I do not know whether or not to feel safe w/biodiesel now that I have everything cleaned or whether I should go back to petro-diesel and forget about bio.

I'd be far more scared of the lack of sulfur these days, a couple % of bio adds the lubricity back in. Gonna be real hard on an engine to be running no sulfer and no bio.

My understanding is the bio will clean out your fuel tank & the like, and the 'problem' is not the bio, but a dirty tank, which should be cleaned up now.

My view of it.

What kind of Biodiesel. B100 or B20. I never had a problem with b20.

10-30% bio.

Can I get high sulfer off road diseel?

I call bull on the "cleaning" bio-fuel does. I have a 930 Case that the tank was cleaned, all new fuel filters, injection pump and injectors done..

I have roughly 50 hours run time on the tractor since the work. I bought a quantity of bio, and fueled the tractor and never ran it a lot after that.. Guess what? about 5 months later the tractor won't start.. can't get fuel through the lines.. get the tank and lines cleaned (again), filters changed (again).. Now, the rack and plungers are stuck in my inline Bosch pump..

Buy bio fuel if you like.. thats up to you.. What I suggest is to put some in a clear container, put the lid on it, let it sit, and watch what happens! Don't see nothing? Well, uncap the jar and take a whiff.. It'll smell awfully rotten after a few months.. something settles out of the fuel.. and if it does it in a clean jar, like it did to me, then tell me about the "cleaning" bio does..

Oh, and it's funny the colors it changes a plastic fuel can too..

I will say, however, I am guilty of running bio in my pickup on a semi-frequent basis (1986 Ford) and never really had a problem. Did have a filter plug up once, but can't prove that was due to the bio.. could have been, but didn't have to be..

I was told bio just don't have a "shelf life".. and I'd say I found out the expensive way.

why not buy diesel and add a fuel conditioner for lubricity and be done with it.the guys from the shop said to not use the stuff gee wiz guys come on.

New John Deere leave the factory with it in the tank.

Speaking of "bio", perhaps you should run some "biocide" from time to time, as the "brown gunk" may be some little critters living in your diesel tanks.
Kill them suckers

OMG. Gots some freaky info here! If youre going to store it for say a month or so, Id recommend regualr diesel, but if you going to run this tractor everyday, run the bio. But where you live will be a factor on the bio, so if its really cold, stick with regular diesel.

It isn't the biodiesel causing your problem. When you don't use the fuel up very fast there is an organism that will grow in diesel and it WILL plug the filter and dirty the tank. Fought that for a few years till I found a product called "KILLEM" that is a pesticide for that organism. Put or something like it in the fuel and change the filter on the pump till the tank is clear and the fuel will be too.

After spending 800 bucks, do you really need to ask?

But with only 5% right

Bio will clean everything it will plug filters for awhile. They started out using it as paint and decal remover but it also ate up the plastic bottles. Now it does have a shelf life of about 6 months unless you have bioextend in it then you got a year. What your describing sounds like bacteria growing in which case you need a biocide and it grows in petroleum diesel too. DJ biodiesel plant operator.

Bio, the soydiesel is not your problem. The gunk that is plugging everything in your fuel system was already there. Biodiesel has solvent properties (just like ethanol in gasoline) that will loosen this gunk which will, inevitably, clog your filters and loosen it from everywhere, including the inside of your injection pumps if it is there. Once you actually get your fuel system clean it will keep it that way and you will have a LOT less problems. Take off your lines, give them a good cleaning, buy a few extra sets of fuel filters initially and you should be good to go. Don't blame the biodiesel. Mike

And sometimes the bio creates trouble when the new machine is delivered. Mark
