Biodiesel fuel vs Diesel # 2

My RAM owner's manual states no more than 5% biodiesel (B5).

Yes but those with newer trucks should be concerned! Especilly the new Fords and Chevys with CP4.2 Bosch pumps. Read your owners manual!

I don't understand all the concern on the bio stuff. I grabbed a tank full quite often in my ole 7.3 power stroke.

Bio is pretty much all we get in Texas... some stations claim B5 others up to B20... it actually is better than the new ultra low sulfur #2 for your engine... the bio acts as a lubricant, it does need a cetane booster to get the same fuel mileage though... I run the Ford PM22 in my F250 and it seems to help.

while we were in Texas in January we took on fuel at the Flying J north of Houston .... while I was standing there I noticed that it was 20% bio diesel and that there was no other choice .... while I couldn't tell any difference in the sound or feel of the truck going down the road, a drop of almost 2 mpg (when you are only getting about 10 to start with) which clearly told me that our truck doesn't like the stuff .... hopefully I'll not make that mistake again

In Iowa its been Biodiesel for some time. I add "Power Service" to the fuel, its seems to help.

B5 is pretty common in both states.

No more than B20 and only if you have no other choice. I got regular diesel all the time we were in OR and WA last summer.

Thanks for the response so quickly. Did you use Truck Stops or what stations had Diesel #2 i.e. shell, chevorn etc.

Yes....
