I've seen several stations offering B-5 to B-20 diesel fuel... Can I get feedback on these new fuels, Positives and Negatives. I don't want to screw up something in my 2001 dodge.Thanks for feedback

 

B-5 means its 5% bio fuel......this would be excellent to buy year round if available as the 5% bio adds more lubricating properties back into the fuel that we lost when the gooberment mandated the removal of sulpher


I myself would run B-20 year round if I could get it

 

Be aware that bio can be hard on the rubber parts of your fuel system.

 

Exactly, Dr Evil mentioned it. We have in Germany already B 5 and the government wants to raise it up to B10. But nobody wants it.
B5 is no problem for sealants.
But B10 or higher is a problem! You have to change the fuel lines to resist against the bio fuel! Pump seals will leak. A change is expensive!
I don't want that ecocrap.
Everbody else can get B100, pure biodiesel it's cheaper than diesel, but with a higher fuel consumption! Most modern diesel over here can handle it.
It's strictly forbidden for my Jeep engine.Maybe you should check with your dealer.

 

Your 01 should have no problems with B20 or even B100 if you can get it, your lines are not the old rubber lines that get soft with the use of Biodiesel. be advised that even B5 will clean your fuel system, after a few tanks be sure to have the fuel filter changed as all the crap will (should) stop there. Its the solvent properties of biodiesel that clean but also soften old rubber lines.

 

Remember! The solvent of biodiesel is aggressive to the pump seals!
That's not funny, when you recognize a fine fuelstream out of your pump...

 

I run somewhere between B10-B20 most of the time on my 07 CTD. No problem whatsoever, in fact it actually replaces the lubricity that was removed when the ULSD was introduced.

I do get a little bit less miles per gallon though. But, I am sending 15-20% less of my money to the terrorists in the Middle East with the purchase of Bio-diesel.

 

If the factory has allowed the use of B10 or B20 it shouldn't be a big deal.
I'm not talking of fuel leaks within the next 10k, it will take its time. Expect it within 40k.
My blown pump seal happend during a vacation with a trailer, really not funny. driving with pure B100. fuel filter clogged every 5-7k . pump seal damaged at 23k.

Whats the cetane number in the US? Ours is 49 on regular diesel. Ultimate Diesel has 55.
Biodiesel also has 49.
In Germany they put synthetic additives into the regular diesel to compensate the worse lubricity of ULSD.There is no lack of lubricity. I have heard that Biodiesel is different.

 

I've been using homebrewed B100 for three years in my CTD.
Only thing i've done is use biodiesel rated fuel hose when I installed my FASS.
If you do use biodiesel, carry a spare filter, especially for the first few tanks.
It's worked great for me, no issues whatsoever.

 

From what I hear and understand the older generation CTD's, once the rubber issues are addressed, are more accepting of higher doses of bio-diesel. I think it has to do with the injectors and fuel delivery system.

One of the local bio-diesel plants runs B100 on their 2nd gen CTD's. And another bio-diesel plant runs B100 in their older Powerstroke.
