I just changed air fliter 26000 miles ProDriver was advering 5.69 mpg, It now is reading 7.04 mpg.I ran 800+ miles and got 7.12mpg. 26000 miles is to many miles. I am going to buy a K&N and clean it every 10000 miles. 1998 Series 60.
Looking at their website they now have a fuel filter minder. Might be worth looking into to know when to change fuel filters.
i would be interested in if the k&n cleanable filter is worth the money or not

Tom, I run K+N's in my diesel pick-ups. My opinion is that they can offer a slight though not measureable increase in performance/economy . The ability to clean rather than replace saves money over time. The downside is that the cleaning/oiling "kit" is not cheap and the cleaning process is quite messy and time consuming. The size of the filters on the larger diesel engines would compound the mess. It is possible that the K+N would offer more worthwhile performance on equipment operated in dusty conditions.
It seems that the K+N has less restriction when new but you can actually see through the filter medium so there are those who feel that the filtering may not be adequate. As the dirt builds up they actually filter better. My trucks do not run in dusty conditions so with periodic cleaning they rarely cause much air restriction.
It will be interesting if Dean Patterson (or anybody else) can install one and track fuel consumption as the dirt builds up.
hi dean, i have a k&n in my powerstroke as well. i have seen the cleanable reusable humongo ones like that in our coaches, but am not sure they are worth the money. anyone have a part number for them and how much they cost?

The filter I use is a WIX 46893 cost $128.00 the K&N 38-2002S/R cost $300.00 NO OIL REQUIRED can be washed 10 times can be washed with a pressure washer they say it's service life is 300,000 miles.
Very interesting Dean. K & N is recommending washing theirs out every 30,000 miles. Over the life of the filter the K & N offers a substantial savings-----$600. Break even is about three paper filters. Is any one using one of these big K & Ns on a DD Series 60?
Don't know if you specifically like the Wix, but the Fram can be bought for about $40 cheaper. The Fram is made by Ecolite which is the same brand that I saw Newell install in Tuga's coach.
the reuseable k&n is $250 bucks shipped on ebay.
i will never drive my coach that much. they claim a performance increase....any comments on that?
