Large capacity oil filters

[TomEichenberger]

One of the problems with the 6.2l is it's reduced oil capacity. Other then price (and potential clearence problems for the off roader) does it make sense to upgrade to a 2-quart filter. Is there a down side? Would it allow me to safely get 3000 miles vs.the recommended 2500 miles between oil changes?

A few of the filter that are GM applicable are;

Fram PH373
NAPA 1794

Any other recommedations/thoughts? It looks like the Purolator L40084 will also work, but I haven't been able to cross reference it yet.

Thanks

I use a Delco PF932 when I can find one. More oil is always a nice thing. :D

The NAPA filter might be OK but unfortunately Fram has many quality control problems - such as visible rust in an otherwise new filter canister and poorly glued end caps which allow dirty oil through the filter - I used to use Fram exclusively and they used to be good - but not now. The research I saw on non-premium filters said to try to stay with Purolator or Delco - there were others mentioned but I try to stick with Purolator. The study also mentioned NAPA Gold filters as being reliable.

NAPA Gold filters are made by WIX.

Wix 51794 and Baldwin B7 are equivalents too. I picked up 3 B7s on eBay a while back for $10 including shipping, so I'm set for about 3 months of driving LOL.

BTW, I have always changed at 5000 miles (Shell Rotella T 15W40) - every oil analysis I have ever done came back fine and said I could run the oil longer.

I have been running the 2 quart filters for many years on my C-10 (vertical filter). I am currently using Donaldson's cross reference to the Delco PF932. The extra quart of oil is good for cooling, extra dirt capacity, etc. etc. With that and my bypass filter, I take 9 quarts to change oil, and still change my dinosaur juice every 2000 to 2500 miles.

Just found this on eBay.

You can also use Fleetguard LF692.

if yours is 2WD and the filter points straight down. The longer filters only fit a 2WD? I've looked and there is a brace/strut/rod that's close but looks like it would clear. The exhaust pipe also looks close but are these features unique to the 4WD? The prop shaft is on the other side and the axle is nowhere close to the oil filter. Anybody running a longer filter on a 4WD?

[Billman]

I used an oil filter relocation kit. It uses a spin-on adaptor in place of the original filter, then a -10 line feeding a dual filter mount. There, I use 2 51794 Wix filters. A -10 line is then used to return the oil to the spin-on adapter.

Total capacity is approx. 10qts.

[Bobbie Martin]

The longer filters only fit a 2WD? [/QB]Its not for the clearance, but because the bigger filters do not have an anti-drainback valve. They are not made to be installed sideways.

[BC Clark]

The filter hangs straight down, it's just that it's a 4WD and I weas curious as to why that would make a difference. Unless people are just concerned about the filter hanging down lower when they are boonie-whomping.

[NH2112]

I think filter orientation only matters on the 88-up trucks (92-up Blazers/Jimmys/Suburbans.) On these the filter mounts sideways, and clearance issues on the 4x4 would prevent it from being mounted vertically. on 73-87 trucks, and 73-91 Blazers/Jimmys/Subs, there are no clearance issues, and anything that would smack the taller filter while out 4-wheelin' would also put a pretty healthy dent in the oil pan.

As I recall, the Chevy performance LT-1 nuts I know say they've never gotten a bad AC Delco filter. I usually use the PF1218 std capacity with check valve.

[jcomp]

I have been using the purolator 2-quart filter (L40084 sounds familiar) on my 4WD K5 for a couple of years with no clearance problems.

[BC Clark]

News I can use, thanks.

In summary for cut & paste:

Baldwin B7
Delco PF932
Fleetguard LF692
Fram PH373
NAPA 1794
Purolator L40084
Wix 51794

Friends don't let friends use Fram.

On the trucks that have the sideways mounted filter, how about tapping into one of the cooler lines and installing a second filter?

82 K2500 (4x4) GMC 6.2 Been using the Fram PH373 for several years now and have had zero problems using this filter. Change oil and filter every 2000 whether it needs it or not...What's up with the Fram filter?

[Animal]

Fram is known for coming apart in the Cummins 5.9L engines and voiding the warranty. I have also read other threads with engine problems using the Frams. To be safe I'd do as the Doctor said; refrain from using the Fram's, but it

[arveetek]

The problem with Fram filters is cheap construction. They use cardboard dividers instead of metal like most other filters. They have a likely possibility of failing internally and not actually filtering the oil. You would never be able to tell, either, just by looking at it if it did fail.

Dr. Lee did a test a few years back, and cut open all the major filter brands. Out of all of them, Fram was the worst, as far as construction goes.

I just bought and installed the 2 qt purolator. I had to push on the exhaust pipe to get enough clearance to get it to go on. Now My exhaust pipe just barely touches the bottom edge of the filter. I've got a small piece of cardboard wrapped in foil in between the two to keep too much heat from going to filter as well as a buffer for when the two move independently of each other. Do you think this is a bad idea?

[CleviteKid]

Sorry Patrick,

I have to vote "No" for your adaptation. At anything above 800F Exhaust Gas Temperature, the cardboard is going to burn up and disappear. It could also just fall out or wear out. I would hate to think of the consequences if your exhaust pipe wore a hole in the filter.

You also don't need that hot spot pumping heat directly into your lube oil.

Have you thought about a quick trip to a custom exhaust shop - they might be able to heat your pipe red-hot with a torch, and bend it so it is at least 1/2 inch away from the long filter.

Dr. Lee :cool:

[Dieselboy]

Great thread - I picked up my NAPA 1794 Gold filter, and topped off the crankcase with a full 8 qts of Delo 15w-40. PF932s have been tough to come by in the past few years, so this is a good find.

[catmandoo]

my dad had a shop for about 30 years and the only filter we used was ac delco,the frams we encountered were either a.leaking b.on so damn tight to keep them from leaking that you had to use a hammer and chisel to remove or c.blown off (this happened lots of times in the winter and particularly on fords).

[farmerpatrick]

Well, I went to few exhaust shops, and none of them would take my money.. They all said to just go back to my original filter.. Is it worth pursuing this further?

[CleviteKid]

Patrick:

You are not out of options. One would be to put a remote filter kit on your truck, and you can even get these for dual full-flow filters, or for a full flow and a bypass filter on one mount.

Hey guys ,thanks for all info. on filters.(DP rocks!)I just got through installing a 2-quart Purolator and 9 quarts of oil ( What do you mean it only takes 8 quarts?!!...doooh!)Any who, the filter fits my 4WD 'burb with no clearence problems from trannie lines, exhaust, or struts. Even better, for you rock crawlers,the filter bottoms out above the bottom of the oil pan.

Thanks!
