diesel additives

I need a little help. I have a 03 monaco with a cummins diesel. I put 65000 miles on it using it a least 2 times a month. I never used any additives. My wife pasted a few months ago so it just sits. I most likely will just take it a few miles up to a river once a month by my house until who knows when. The question is should I start using some kind of additive to keep the fuel fresh?

Cummins manual states no additives. I have never put anything in. I am not saying you won't run into a problem but for the most part with todays fuels you shouldn't need to add anything. My Father has had diesel equipment dating back into the mid 60's and has never used additives in the fuel. I just changed my two fuel filters on my Coach this weekend and I cut them apart to see what the filter looked like and after two years app. 12,000 miles on them the were a little dirty towards the bottom of the filter but looked good still. Again, as you will find on here others use additives on a regular basis as a preventive measure , others do not.

A biocide to prevent algae is all that's needed.

So sorry to hear of your wife's passing....
unfortunately we all are experiencing that more and more as each day passes....

Good on you to keep rv'ing !

Your enemy is water in fuel....
condensation from temp changes that MAY form moisture in your tank...
i.e. not using it enough to turn over the fuel sitting in your tank...

This is a personal decision and some decide to add some, some don't - up to you...

I personally add just enough Power service to my tank to help with the potential of moisture... it's not expensive and imho just a bit of insurance....
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

Biobor is needed to prevent algae,if any moisture is in tank algae WILL grow and block your filters.
