Fuel Filter Life is always lower than Oil Filters Life

[Ngrgs42]

I have a 2022 Ram 3500 6.7L HO love the truck but the fuel filter life keeps decreasing way quicker then the oil filter life, the oil filter is 9-10% higher then my fuel filter in the truck. I had to already change the fuel filter at around 7000 miles and now the truck is slightly more 15,000 miles on it. I get Shell diesel when I am towing or running around with the truck. Has anyone else have had there truck do the same thing and how did they fix this issue from happening to there truck.

The oil life is based on an algorithm that takes into account multiple variables in order to estimate the percentage remaining. The fuel filter life is based primarily on mileage. There is usually a difference of a few % between the two. That being said, I’ve never witnessed a truck that was showing 10% difference between those two monitors. Maybe you’re in need of a software update?

Going to bring this back up. My first oil change was early and I didn’t do fuel filters early so I didn’t see the disparity last year.

This year I changed both the oil and fuel filters at 13,746 miles. I’m currently at 17,953. Both filter life meters were reset.

The fuel filter life is at 68%.

The oil life is at 72%.

I do know what when I reset the fuel filters they dropped to 99% almost instantly, but oil life didn’t.

So, based on mileage the oil life is accurate for a 15K mile interval.

Fuel filter interval is on track for ~13K miles.

I can’t find anything in the owners manual that would cause a shorter fuel filter life.

Anyone else have the same experience?

I would also think that operating conditions such as towing that increases fuel consumption would significantly impact fuel filter life compaired to oil filter life.

Same exact experience with my 2022. I do fuel filters and oil at the same time and reset both. My fuel filter life will drop to 99% rapidly but oil life does not. There is usually a few percentage points between the two, with the fuel filter always being the lower of the two. I did my last service on September 30th of this year. 37,775 miles at the time. I have 38,222 on it now. So just under 2,500 miles so far and oil life is at 84%, fuel filter life is at 83%. I try to keep idle down as much as possible. The truck sees a mix of highway and local driving. Intermittent towing.

Maybe, but no mention of anything less than a 15K mile fuel filter interval. Oil life is mentioned as possibly less than 15K miles.

Since it may be based on a algorithm (saw that mentioned in the past) any chance it’s based on the evic mpg? Like the truck knows the filters are only good for filtering so many gallons of fuel and based on your mpg that’s the life it gives you? Mine does same as you guys too fwiw.

Could be, but if that were the case it should go by hours as the flow rate thru the filters doesn’t vary from 8 mpg to 20 mpg.

I just pulled a heavy fifth wheel 2000 miles. I changed oil/filter and both fuel filters just before leaving. My oil is at 84% left and my fuel filters are at 86%. I burned 210 gallons of diesel. At that rate I should get around 13000 miles before both are at 0%. I would have thought I would have less filter life than oil life left due to the amount of fuel. Who knows?

It really doesn't matter where you buy your fuel as long as it is being turned over fairly quickly . Diesel unlike gas is single source so multiple stations within a give area are selling the same fuel regardless of the brand on the tanker if there's one at all . Fuel filter life is also dependent on the quality of the product sometimes we get fuel that just has more than usual crap in it . As expensive as they are I try to get to 10% or less . Fuel jelling in cold climates is the worst ! When I owned rigs I ran anti gel in my tanks and wrapped my fuel filters in foam . 35years and never had them jell but I passed many trucks sitting on the shoulder waiting for a hook because of it . Cheap insurance .
