Fuel water separator filter

What brand truck.
What type filter?

 

Cummins X15 performance fuel problems, filters plug up very fastt

Are you using factory filters? Original part number?

The Davco is easy to sway micron rating? Maybe someone put it one too small. Engine side should be 5. Consider going up on the Davco to make the filter service last longer. Maybe dirty fuel this trip? Make sure the bowl is getting cleaned out at PM, not just filter slap.

 

Why are you doing oil changes so often?

 

5 Micron

Good info in the post link I shared

 

Depends. If you want to keep the truck forever, then keep doing what you're doing. If your plan is to trade it in at 500k with trashed internals, then go with the manufacturer's specs.

 

Sir, first find out if you have a Davco filter or the standard paccar. Most dealerships are ordering the Davco because it’s a better piece of gear than the paccar. I go 32,000 miles or a bit sooner if convenient oil change using 15 W 40 Delo XLE. I haul reefer coast to coast. 565 2050. If you’re using the Davco mind you if the level is up halfway it’s still doing its job. It needs to be replaced when it reaches the top. Be mindful also that a bad batch of fuel can make that filter expire very quickly. So you’re not wasting your money, if you still end up changing your oil at 14,000 miles I would switched to the non-extended life fuel filters and oil filters. It will save you a lot of money. The new fuel filters and oil filter for that engine are extended life and pricey.
