Ya know I have no idea I trust the YODA OF FILTRATION on this site. AH64ID he spit out the numbers of the best filter for our truck and thats what I get. He has never let me down with the info. He has info to back up such claims. I can get the filter # for you if you need!!! I have it wrote down in the shop about 300 yards away. I can almost guarantee that its synthetic.

After posting I remembered that I put all the info like that on file in computer. Its the Donaldson ELF7349 hope that helps if you needed it.

Just today I bought 6 Donaldson P558615 oil filters, just wondering what you were paying for them up there in MT. Just wanted to compare pricing, that's all.

I believe it was around 12 bucks. Got mine from the Freightliner dealer. Mine is the extended life filter I have an FS2500 on it also so I tend to run my oil just a little longer than most. That's the reason for the better filtration. Before I found out about the Donaldson I ran Fleetguard syn and had no problems except the oil filter gasket coming off if that was a problem at all that sounds a little petty to me but each to their own.

The Donaldson ELF-7349 and the AMSOIL EaO-80 are one and the same filter... ... ... Very highly efficient filters 98. 7 percent at 15 micron, 50 percent efficient at 7 microns.

i did the once on my CJ7. Never noticed seal was still on filter housing. Started Jeep and in 20 seconds it spewed out a quart of oil all over.

Needless to say, I check and double check every time now.

Last two times I changed oil using Wix filters the ring stayed on. I always clean surface before putting new filter on and caught it then.

Several years ago there was a lot of discussion here about how the interior filter media of the Wix and Fram oil filters would collapse. I don't know if that has changed, but I've stayed away from both since I bought the truck new.

Also, why would you crawl under truck to change filter. Loosen a couple of hose clamps on turbo intake and intake comes right off. Filter is right there, easy to change

I crawl under the truck to change the oil filter because it provides me with an opportunity to inspect the undercarriage and other parts of the truck and engine that I don't normally see.

Doh! This is what happens when you don't catch it... wow did I feel like an idiot. The oil pan was empty in about 10 seconds, which was about how long the truck was running before I saw the mess while backing it out of the garage. Shut it down on the spot and went back to the store in the car for another $45 worth of Rotella and 8 bags of cat litter.

Sure enough, the seal was stuck to the filter mount, until I started it, then the oil psi just blew it out of place. Stupid. I did notice the filter felt strange as I tightened it on, but didn't investigate further. Lesson learned. Good thing it happened right away instead of 10 miles down the road.

gotta get under there anyway to get the drain plug...

As for the filter, I loosen it first, then slip a parts bag over it, unscrew it, immediately put the new one on, tighten it, then put the drain plug back in. . One time under the truck on a creeper and done. .

I always check, however I never have one stick. I always smear a film of oil on the seal and always install hand tight.

I always open the first bottle of oil and smudge a little on the seal and then hand tighten 3/4 of a turn. My first job was in a Garage changing oil, and it was taught to me by the very experienced mechanic/owner of the shop. I have never had a seal stick to any engine. I have had to fight many oil filters when someone else had used a filter wrench to tighten them. I do use a filter wrench on my boat filter because I can't get my hands in to hand tighten it, but I do make sure it only turns 3/4 of a turn.

I have never had an issue either and I go 25,000 miles between oil and oil filter changes. I change the filter from underneath, use a clean rag or paper towel to wipe off the mounting surface before installing the new filter and always coat the new filter seal with clean oil.

Same here. I don't get the tighten like crazy crowd.

I've had a few of them stick on passenger cars with cheap filters.

IMO, if the filter base is wiped down with a clean towel each and every oil change, double-gasketing would be a non-issue... . I've been changing oil in vehicles for about 35 years and cleaning the filter base was something my Dad was a stickler about.
