Diesel injector cleaning?

I have 60,000 on my Cat 3126E....do any of you add some kind of injector cleaner as a preventative maintenance?...if so, what brand.....Engine runs well but mpg seems to be lessening a little over time...thanks RKL

Whether it really works or not, I add a bottle of Power Service (silver) about every other tank. You can get it at Wally World. They have both a warm and cold weather formulation.

If your losing fuel mileage, maybe a tuneup is needed??

Although our present MH is gas, I've owned diesel pu's for a number of years. I would use a Powerservice/Marvel Mystery Oil mix, 8oz&4oz for each 25-35 gal in the white bottle during the cold months and the same mix in the grey/silver bottle during the other months. Another produt that I became aware of several years ago is called SeaFoam and comes in a 16oz can. I would put in 1 can per 25 gals in my diesel and gas vehicles (3) times a year and other lawn tools boat motors when storing for the winter. Sea Foam | Home Both of these items can usually be had at Wally World.

I haven't used fuel treatments in my newer motorhome but have used it in previous diesel motorhomes and in one old diesel tractor I used to have. I added Power Service sold at Walmart in a mid 1960's Ford Diesel tractor and the effect was immediately noticeable. Exhaust smoke was reduced and inector pump noise was very much reduced. This sold me on the product at that point in time but we do need to keep in mind this was an old well used tractor without the electronic controls on newer diesels.
