Any Input on what a good fuel treatment/cold weather fuel additive would be. I have always used power service in my 6.5, but since i have the newer LMM engine, I wasn't sure what the best additive would be. With all the new low sulfur diesel talk, don't want to use anything that will cause headaches with the new emissions equipment.
Also, how often do you change the fuel filter. I have approx 40% left according do instrument panel info...thanks.
