What has the experience been on running B20 on the older 6.9l and 7.3l diesels with the IDI engines (1994 and older)?

Has anybody had there Stanadyne IP pack it in due to problems with natural rubber o-rings?

Any other things to watch for (other than the fuel filter changes) during intitial conversion?

 

Hmmm...no action in the IDI forum. Lets slide this one down to the BioD forums and see if we can get you an answer.

 

I've been using Biodiesel in 9 different diesels with IDI and without for over 2 years now and not one fuel related problem yet. Just remember to change out any natural rubber fuel lines and change your fuel filter early after changing to B-20 or higher.

FABMANDELUX.

 

I've got a 1992 idi which I have run many tanks of bio diesel in the last 14 months. just change your fuel filter soon after switching. as for the natural rubber lines, they should be ok as long as there is no considerable seepage so that the stuff gets on the out side and eats away at it. I use either B 50 or less made out of waste vegetable oil. If you can get stuff made out of soy oil, that would make it burn better. if your idi is not turbo'd, it will not burn the bio diesel as good cuz it takes more oxygen and boost to burn that stuff.

 

Actually BD is an oxygenated fuel, that is each molecule of fuel carries 2 oxygen atoms. Petro diesel molecules have no oxygen atoms

 

I think you are right the reason BD tends to burn cleaner is because it is oxygenated while petrol diesel is not.

Does this mean we can look forward to diesel regulations that require oxygenation much like we did over the last 15 years with gasoline in California? I sure hope not but I can see it coming.

If corn (ethanol) is the answer to gasoline oxygenation, then maybe soybeans (biodiesel) is the answer to diesel oxygenation.

 

BD is more environmentally friendly than Petro for several reasons. Even B2 shows reduction in CO and CO2. Pure BD is CO2 neutral in that all of the CO2 released was initially removed from the atmosphere by the plants that produced the oil seed crop.

Additionally BD is biodegradeable at about 3X the rate of Petro so spills are less problematic

 

It would not supprise me if oxygenated diesel will be the next thing refineries will have to content with once we they have made it over the ULSD (Ultra Low Sulphur Diesel) hurdle later this year.

 

They can solve both problems and address the lubricity problems associated with ultra low sulpher by going to a mandated B-20.

Just think a 20% increase in Diesel supply without increasing refinery capacity

 

It does make a lot of sense doesn't it.
