I have an 07 5.9...

I have always tried to use B5-B15 bio-diesel, but, my source for bio-diesel has dried up. As far as I can tell around town, only Murphy Oil advises that their pumps "may" contain up to 5% bio-diesel, but they don't say for sure.

I'm sure this has been asked many times before ... What are the most cost effective fuel additives for my 3rd Gen 5.9 Cummins?

Marvel Mystery Oil? Walmart 2-stroke? Diesel Kleen?

 

I use POWER SERVICE

 

Here is the info Power Service Products, diesel fuel additives, prevent gelling, clean injectors, disperse water, boost cetane, reduce emissions, improve fuel economyPower Service Products, diesel fuel additives, prevent gelling, clean injectors, disperse water, boos

 

Cool, and a $4 rebate if you buy the 80oz bottle of Power Service from Uncle Ted! (Expires 8/31/12)

ive had a bunch of people telling me lately not to you use any type of additive in my 06.... they say that its hard on the injection system... is there any truth to this ? it seems very hard to find a diffinitive answer to this question...... i was using diesel aid, and before that in my 2000 howels...

 

Make sure it is ULSD compliant and alcohol free.

Good info here!
