Depends on the blend.

Sorry, but wrong. If it is retail biodiesel it has to meet ASTM standards. If someone uses any other type then shame on them for not knowing any better.

And BTW the U.S. Military contracts biodiesel blends as their diesel supply on bases all across the country.

Uneducated people is the problem, not the fuel if it is retail biodiesel.
NewsW wrote: In any case, I see no rational arguments for biodiesel --- when the old fashioned diesel does the same job better and with fewer unknowns.
Keep convincing yourself of that.

As of 2011 Dodge, GM and Fword are all B20 compatible. Cummins has approved/certified the HPCR ISB engine series for B20 since it hit the market in 03. Dodge didn't because of their lackluster filtering system. With the amounts of people that have run a biodiesel blend in the HPCR Cummins powered trucks where are all of the horror stories of those Bosch HPFP's failing in the Dodge trucks? Guess what? There are very few.

What Peril? I bought my truck used in 05 with 28,000 miles on it and I now have 182,600 miles. I started running biodiesel blends in 06 and haven't looked back. I have easily burned over 6000 gallons of biodiesel anywhere from B1-B100 and have never once had to change a fuel filter out of my regular schedule. My fuel filter change only happens when I see a consistent drop in pressure to around 15 psi from my normal 21 psi.

We have to agree to disagree.
ASTM standards is the joke on user out there.
There is no enforcement of the standards across the board at the retail level.
No consistent, nationwide, independent testing and sampling.
Nor is the standard itself sufficiently robust even if all fuel met standards --- it keeps evolving to add new issues as it is discovered.
At the retail level, ASTM is an aspirational standard that is akin to an API oil grade --- compliance and enforcement is entirely voluntary.

thanks barry!
And the govt is supposed to tell them not to go offline? If you took the time to get educated about the subject, you'd find the Govt, Dem or Republican has very little (virtually zero) control over the price of gas.
Not saying that fuel is not filtered at stations but I question how often they are changed to prevent one from receiving contaminated fuel.
Compare the number of times you fuel up versus the number of times the pump is turned up and then think about the number of times you have seen a cover off the pump and someone changing a filter that is not much larger than the one on your pump. Seems to me that filters would need replacing at least once a week and I don't see that happening. Only time I see a cover off a pump is when someone is doing a repair and the nozzle has a plastic bag over it because it was taken out of service

I also have never seen a filter on a gas pump but I have also never seen anyone replacing filters regardless of type of fuel.
I stopped at a station where new pumps were being installed and asked about filters. Guy doing the installing said they have filters in the top section before the nozzle.
