Beast
This thing is HUGE! installed it and drove around a couple days and my oil got cleaner that it was before. Yes I installed this mid oil life(didnt change the oil) because i wanted to test the rumors about it. They are all true. This thing cleans the oil like magic.

Solid Donaldson Product
Impressed with this filter. We use Donaldson filters at work on our CAT equipment so I know their reputation and this filter that threads onto the 7.3L is a great upgrade. It is absolutely a tight fit. I found that the tight fit on my stock height 4wd OBS was both length (to get the first thread started) and diameter (clearance to the oil pan). It is larger both in diameter and length than the stock filter, so if you don’t have a big filter wrench, make sure you get a big one that will handle a 4 5/8” +/- filter (I failed to measure ahead of time and still need to order one because my 4.125”-4.5” capacity won’t fit). Holds about another quart of oil over stock so don’t forget to add that in on your total change amount for refill.

Good for a lifted truck
Have clearance issue on a stock 4wd f250. I had it on for 3 weeks and found a crease on the bottom of the filter from the sway bar. Happy I caught this prior to damaging the filter mount or worse. I drove mostly on the road.
Totally bummed as this is a great filter and changed back to a stock filter. -
Donaldson Blue Extreme
After reading how much bigger and better this filter is, I decided to order one and try it on my ‘97 F-350. As others have stated, it is an extremely tight fit, but it did thread on. The filter is 11.75” long and not only barely fits length wise, but also barely clears the oil pan diameter wise. My oil pan had some road grime and oil buildup on it and some of this ended up on the filter from threading the filter on just because of how close it was…it was barely rubbing the road grime (but not the pan). Time will tell how much better filtration this filter has, but it’s a Donaldson so I’m sure it will be great. Riffraff has by far the best price on these.

Donaldson extreme oil filter
After ordering this filter I had my reservations but I was optimistic about it because of all the great reviews. When it arrived finally as I live on the other side of the country in georgia it was about a weeks wait (not a big deal) I opened the box and just laughed. This thing makes oem motorcraft filters look tiny even though they really aren't. This thing puts that motorcraft filter to shame. It hasn't been under the truck but a couple days so I look forward to seeing how it does. So far so good. I like the extra oil capacity, more filtration and longer oil life which is exactly why I bought the filter to begin with. My next purchase will be insane diesel bypass oil filtration system to really help keep the oil cleaner. I use my 7.3 for my business and the more protection I can give it the better as its too expensive to buy a new truck as of right now. So if I can keep this ole girl going that's exactly what I'm going to do.

Donaldson Extreme Oil Filter (High filtration media)
Fitment on the 2000 super duty 7.3 diesel was great, The filter is almost a foot long and when installed it's about an inch below your oil pan and holds about 2 quarts of oil.
