Oiled air filter vs standard

Currently I am running an AFE oiled air filter, and it does the job. We live on a gravel on, so plenty of dust daily. Debating on going back to a standard dry air filter and replacing it every 6-8 weeks. My wife drives it most of the time and knows how to check and replace the current filter, but way over oils it.

What air filters are you currently using in your CRD

Oiled filters have superior flow but at the cost of filtering ability. I stick with standard dry filters for this reason. The CRD intake is particularly good at picking up crap partially, I believe, due to it's positioning.

WIX dry or NAPA gold equivalent.

I think a dry paper filter is best too.
But replacing it every 6-8 weeks? Are you driving through thick dust clouds everywhere you go? How do you see while you are driving? :shock:

You could get more than 6-8 weeks of use by periodically removing and shaking out your filter and blowing it out with compressed air.

FYI: Another issue worth mentioning which I do not think has been brought up is the oil contamination of the MAF sensor when using an oiled type air filter. I ran into this with my K&N causing some erroneous trips of a DTC when the MAF got oil fouled from the filter oil treatment. I have since returned to a good quality dry type air filter after cleaning the MAF thoroughly with some spray cleaner designed just for MAF cleaning and have not gotten any more DTC's due to this problem... :roll:

While the washable high flow air filters do offer some advantages over dry type filters to some diesel engines like my Dodge Cummins with all its high performance parts, I do believe that our smaller Jeep CRD engines are better off with a dry filter system as you will never be restricted on air flow due to the lower air flow demands of the engine... Unless of course, you allow your paper filter to get super dirty... :2cents:

Thanks everyone. We drive 5 miles each way on gravel in and out of town probably 2 to 3 times a day. Usually it's pretty dry, so the gravel dust never seems to end. Appreciate all the input.

I think the paper filters usually have the best filtration anyways(but "more" restriction,) so I would just stick to cheap paper and replace as needed since you are in such a dirty environment. Plus these engines only make 160-200 hp depending on your tune situation which just means that there is not a whole lot of air being pulled through them anyways. The stock filter has a decent surface area so you dont need a super free flowing filter.

That said I run an AFE oiled filter and have not found any oil in my intake tract. I figured it would pay for itself over time vs swapping filters.
