What's Going On With Diesel?

Just wondering if anyone else has noticed the drastic drop in mpg with diesel fuel lately? Mine has dropped about 3mpg and I have talked to others who are saying the same. My 7.3 international 4700 at work is suffering too. Ay idea what might be going on?

Yes. Refineries are putting in 20% biodiesel instead of 20% kerosene for winter blend. A lot of farmers around my neck of the woods complaining. Injector problems and still having gel up issues. This is the first year of doing so with govt subsidies. A fuel delivery driver told me Sunoco was the one who started doing it first. From what I was told.

Funny you bring it up.. i track mpg's close like, and i'm down two full mpg's without any reason i can figure.. my average has dropped from 17.5 to 16.3 overall, and with the exception of the last tank (16.4) i've been in the high 14's and low 15's for at least three or four weeks..

There are at least seven brews of fuel throughout the country at any given time.. then there are winter blends, summer blends, and even local brews some large cities mandate.. i fuel at the same fuel point, though, damn near every time.. winter blend here varies only slightly from summer blend... I cant wrap my brain around it..

Someone on here said if you had warranty work regarding fuel related issues on the 6.7's that Ford is not honoring the warranty if the was more than 5% biodiesel found in the system. Of course that's if they check. Again, only what I seen in a thread.

6.7 says B20 right on the door badge.

Anything over 5 points in a 6.4 they can give you a hard time about.

And testing it isn't hard. Put a sample in a glass bottle, and freeze it. The bio and dino will separate.

OK. I didn't remember exactly the post I was referring to, but anyway. Sucks for those having dealer warranty issues.

I figured it had something to do with the refineries and the EPA. Hopefully they will get back to normal soon!
