B20 diesel to use or not

[Frank 4]

Hello, I was traveling the I-5 corridor in California most fuel stations had B20 diesel. Does anyone have experience or Knowledge on using it in a 2015 Jayco Seneca? The motor is an ISB6.7 Cummins.

I have no experience with the ISB Cummins but I do know you will get less fuel economy with B20 than B5. Also, higher levels of biodiesel will clean out the fuel system which isn’t necessary a bad thing but you will have to replace your fuel filters more frequently.

Welcome to the forum.

I'd check with a Cummins dealer.

If Good Sam says no... that must mean something pretty bad!

Problem with "bio" it loosens any dirt and sediment in the tank causing plugged filters. We had tons of trouble with our maintenance fleet when I was in Public Works.

I the Ram applications, the ISB 6.7L is B5 biodiesel compatible from 2007-2013. It is B20 compatible from 2013.5 to present. You would have to check with Freightliner for sure, but I would assume the same compatibility in the Seneca chassis.

Ran it on Florida....fuel was orange verse the normal yellow clear look. Couldn't tell a difference but it didnt have an odor.

Be sure and buy some extra fuel filters.
