Hooray for Big Filters!!

[Rolling]

Gm finally has a big filter for the gmt-900 trucks!!! The catalog lists the replacement filter under the Traverse for now, the new PF-48 is a PF-63

It's about the same size as the PF-59 was to the PF-46.

I like it because it's a more appropriate sized filter for the area the filter goes on the truck.

So Go! Be merry and filter more oil!!!!

Because the regular one isn't good enough? Have you ever cut a filter open after an oil change?

 

 

To each their own...

I think he may be referring to an easier filter removal? Thats just my guess tho

[jro909]

bigger isen't always better....

And no, unfortunetly the PF-63 is not an "interchange" for the PF-48 yet. Yes the filters are very similar but If you look up what oil filter the GMT-900's are specd for, it is still the PF-48 not the PF-48 or PF-63. Yes the PF-63 size filter will screw on and probably work fine but untill GM actually lists the PF-63 as an interchange for the PF-48, I am sticking with PF-48 for now. If you truck is under warranty, I would strongly advise you to do the same.

YEA, I'am still using the PF-48 but shake my head every time I change it,, what a crappy little filter for a large displacement H.D.

truck! These trucks are used in very harsh,dusty,dirty enviroments come on G.M. give us a heavy-duty filter for our Heavy-Duty

trucks! And as stated above don't do anything to give them a reason to void your warrenty Dave

The environment a truck is used in has zero bearing on what size the filter would be. There is no reason to put a bigger one on, ESPECIALLY if it's used in a harsh environment- the taller one is more likely to be damaged.

[amc31b]

I agree with both sides of this discussion but will explain why. As long as the filter doesnt extend below the oil pan (which even the pf-63's don't) there is no extra risk of the filter getting damaged.

I do agree these filters are too short for a large engine, where long oil change intervals are the norm though. A taller filter gives you more room for a taller (thus larger area) filter element which means increased filter capacity. Increased filter capacity is important when you do extended oil change intervals, Because the filter (and the oil) doesnt get changed as often, the filter has a higher chance of becoming clogged with particles before it could be changed out (which obviously happens during an oil change). The chances of your oil filter becoming totally clogged are very slim but a taller filter would lower the chances of that happening even more.

The second and most obvious advantage to a taller filter would be easier installation and removal. Because the filter is taller and extends down further, you dont have to reach your hand so far up into the engine to grab it.

As for the "harsh environment" part of it, I think the guys above me were talking about harsh driving conditions such as off road. The only real extra requirement of the oil filter would be that the filter have a thick, strong can to avoid damage from sticks and debris possibly hitting the outside of the filter. We already know that even the taller filter doesnt extend below the bottom of the engine so that part of it is OK. Harsh, dirty, dusty enviorments are actually a bigger test to the air filter, as the air filter's job is to not let dust or anything but clean air enter the engine.

This is really where the cotton oiled filters such as k&n dont do so well. The thin cotton material and its oil simply cannot and does not filter out particles in the air as well as a thick, well designed paper or phenolic/synthetic (most wix air filters) elements do. K&n filters will work just as well and be just as servicible for any normal driving conditions but in harsh, dusty, (desert / off road) enviroments they will need alot more care in the form of cleaning and oiling to keep dirty air out of the engine. Even k&n themselves admits this in their filter care instructions, I know because I have a k&n intake on the car in my sig.

I hope this helps somebody, I like having these informative discussions.

There is no way I would put a filter on that is not listed as a replacement filter for GM if it listed as a replacement then yes. You better hope something does not happen and you take it in as what ever happened to the motor they WILL blame it on the wrong filter. As said bigger does not mean better.

 

I have never seen a clogged oil filter if one is clogged then you have bigger problems.

Why so excited? What do you think this longer filter is going to do when you put it on your truck besides hang down a little more than the correct filter? How much more oil do you think it is going to filter? There is going to be 6qt. of oil to filter even if you go ahead and use the incorrect filter. If the one you listed is "more appropriate", why didn't the engineers at GM design it for the trucks?

 

Horray? Be Merry?........

[RockySierra]

larger filter = more filter media = longer oil change intervals.

[MikeNH]

People need to stop complaining about the filter location. This is my second GM truck with the filter in that spot and I've never given it a second's thought. Buy a damn cup wrench to fit the filter and move on.

Not a good idea to go by that but it's your truck.

 

 

For the guys that complain about the filter location, get a Tundra and do an oil change on one of those....... there is nothing wrong with the location on our trucks and it is very easy to change.

Totally agree with both you guys. With a cup wrench there is no easier oil change than on a Silverado. How much easier could it be? I gave up on Tundra oil changes when I was driving the Yota. The cartridge, the skid plate....life's too short.

 

Compare the access of our filter to where they hid the filter on the Ford F-150 Ecoboost.

By the way, the FL500S Motorcraft filter on the Ecoboost will screw onto our trucks as well. Anyone game? I'll pass. Nothing wrong with a Motorcraft filter (it's bigger than the PF48), but it wasn't designed for our engines.

Its the same thing that the monte carlo/grand prix crowd were doing 10 years ago with putting a larger oil filter on. Nothing wrong with it, as long as the filter gasket and the threads are all the same you wont have a problem. Oil filters are made by the companies and the car manufactures pick one to put on that fits, I wouldnt worry about it.
