Been using B5 diesel the life of this truck and last time I went to fuel it up in town my favorite station changed to B20 fuel. I drove all over but everyone is now B20 except an arco and a shell with no labeling on their pumps.
Apparently later model trucks are equipped with another filter (water separator?), but I was hoping to hear from others with a similar year dpf equipped truck, and if could provide any tips for when you made the transition from B5 to B20.
Flush the tank first? Add the $600 separator kit? Dont worry and continue hauling around the spare filter under my seat?

Thanks

Yup, not an issue.
And not a fan of Arco.

From RAM TSB 14-007-06 dated August 25, 2006 :

"Models: 2006 - 2007 (DH/Dl/DC) Ram Truck (Heavy Duty)

NOTE: This bulletin applies to vehicles equipped with a 5.9L High Output or a 6.7L Cummins Turbo-Diesel Engine (sales codes ETH or ETJ respectively) that were built on or after March 07, 2006 (MDH 0307XX)."

"- A maximum blend of 5% biodiesel (B5) is acceptable as long as the biodiesel mixture meets ASTM specification D-975, D-975 - grade S-15, and ASTM D6751. A biodiesel fuel blend that is higher than 5% is not acceptable without additional fuel processing because these higher percentage biodiesel blends contain excess amounts of moisture which exceed the water stripping capability of the on-engine final fuel filter. Should a higher percentage biodiesel fuels be used an auxiliary water stripping filter will be required.

- A maximum blend of 20% biodiesel (B20) can be used by government, military, and commercial fleets who equip their vehicle(s) with an optional water separator, and adhere to the guidelines in the Department of Defense specification A-A-59693 (in addition to: ASTM specification D-975, D-975 - grade S-15 and ASTM D6751)

So in short, they feel you need a better water separator.

OP, there is literally nothing wrong with B20 in your truck. Scott’s recommendation on the TSB is, or maybe was correct. But back then there was no standards on b20.
Worst case and I mean worst case, it might clean up your tank or fuel lines and plug a fuel filter or 2.
And if you’re not running secondary filtration with that OE filter setup, you should be. Your wallet and injectors will be happier in the long run.

Even though he’s not deleted, if he was, what would he have to be doubtful about to make his truck smell like French fries ?
