Fuel Preservatives

[Johnny G Bagwell]

So I have a 2020 ram 2500 6.7 Cummins. I am in Army and I'm headed on a deployment. I have a 52 gallon tank now. My wife will probably barely drive my truck while I'm gone. What is a good diesel preservative that will keep the fuel from turning rancid and keep fungus from growing in it? Any thoughts?

Sta-Bil for Diesel fuel will work.

Howe's was recommended to me by two diesel shops, one being the local Cummins shop. So it's what I use in our RV's Cummins, as it tends to sit a while between uses. Never had an issue since I started using it.

Stay safe, and many thanks!

I use Star Tron for diesel. This is one of the best-tested products for fuel stabilization. Many years of use and has never let me down. This product will also work for gasoline.

Thank you for your service and please stay safe.
