Diesel Fuel Grade
I am a new owner of a 2001 diesel pusher and have read articles about low sulphur diesel grades. As long as I am using highway fuel, do I have to worry about fuel grades?

I would not worry about US diesel on the road. ULSD has not harmed my Cummins ISC one bit, and I remember there being a memo from Cummins about ULSD not having harm to older ISB and ISC motors. I do find that my injection system (2001 ISC is a CAPS based motor) does benfit from a full tank of treated fuel once a year. But that is as far as I go other then using additives to stabilize the fuel during storage.
