Fuel additive recommendation by Cummins
A recent post on The Turbo Diesel Register mentioned that Cummins officially endorses Power Service Diesel Kleen and Diesel Fuel Supplement. I own a 2016 Ram 3500 Cummins Diesel with less than 20k on ...

WOW... Please share why it is bad to change any fluid little bit early, like 10 percent?
Since you asked my opinion m....... It is a waste of money. I get an oil analysis done every oil change since I can have them done for free. We provide UOA's for our medium and heavy duty fleet customers. I have done a 10k oil change and a 15k oil change and the UOA showed no significant difference between the wear metals, mineral additives, or fuel dilution.
So my conclusion based on actual testing(instead of he said she said) is that it is a waste of money to change your oil too soon. Everyone should get a few UOA's done so they can know exactly how long they can go between oil changes. The more oil wasted multiplied by everyone in the world means that more oil is used for their "cheap insurance" which means my fuel and oil cost more.
So what is your experience besides this "Cummins engineer"?
You did notice... I'm using the word percentage and not miles, right?
I'll stick with doing all my maintenance 10 percent early. Oil sent in to be checked about once a year for me.
My experience with Cummins? By the way I'm speaking about the whole vehicle just not the power plant when I'm talking about backing up maintenance 10 percent. Used to watch 53 blocks work even with cracks in them. Notice how Fleet guard oil filters now have plastic wrapping on them for about the last 5 years. Gee wonder why...(and leap forward by the way). Stored in warehouses and dealers not storing right, etc
I can tell you with my 2001 5.9 the maintenance schedule doesn't even mention power steering fluid. Well put some spinner oil seperators on those class 8's, as they have enough oil pressure to spin out the soot. And lots of fleets are getting lots of miles between changes.
For me changing fluids 10 percent early works about the same anyway. I joined my dealers "presidents club" (I think its called) many years ago that gets 10 percent off. I don't think they offer it any more, and I have remember to ask or I don't get it.
(side note) being you see oil testing results...seeing any results in the new oil spec yet? Spec "K" or whatever they are naming it.
