Series 60 DDEC 4 oil filter

My take on Wix (automobile centric view):

Their business cinsisted of making high quality "generic" filter lines for lots of premium applications, similar in quality to OEM filters for lower volume production models to a large degree. Sold through NAPA to repair shops under the "exclusive parts provider" arrangement that used to be commonplace. Basic ally if you had a diesel pickup, a bmw, or mercedes (or more exotic) they had your application for oil and air filtration at a significant discount to OEM with similar quality. WIX was good stuff quality wise.

I was a huge fan of Wix until they created an oil filter for Ford diesel pickups that included a cap glued to the oil filter that led to many if not most shops (or at least lube centers) throwing away the clients OEM cannister lid because they thought it came with the oil filter. Next oil change somewhere that didn't sell Wix they had to order a new oil filter cannister cap oem from Ford to change the clients oil filter. I bought a few new oem caps due to this bull****. I liked WIX prior to this, after enough going in circles due to that crap I soured on them. Gotta hate it when C-suite decisions push envelope too far and screw the customer.

Does NAPA no longer sell WIX? Wouldn't surprise me if this is why. It's a known perturbation among Ford Power strokers.

My 2c

 

Napa branded filters are made by Wix. Detroit OEM are Donaldson. Fleetguard is owned by Cummins.

 

Ask Napa when do they have their filter sale? You can get them a whole lot cheaper then. I would have to check, but I'm thinking around 10-12 dollars for that 1971 filter on the sale.

 

The first number tells you what it filters. 2 is coolant. 3 is fuel. 4 is air. 5 is oil. Drop that number and that is the Napa number as they are made by Wix.
There are some letters that can come after those numbers. Those normally specify an extended life filter and cost extra.
When Napa does their 50% off twice a year sale it is what I pay everyday for Wix. Wix distributor takes a bit and Nape gives great service to me.
If you are doing the extended oil changes spend the extra money for those filters regardless of brand.

 

If you put "MP" after Napa #, i.e. 1971MP, even cheaper. Filter will come without packaging. Just clear plastic wrap. Not every filter is available MP (master pack)

 

NAPA gold is a wix.

Napa filter sale is best price.

Or get a commercial account with Oriely, all most equal to napa price.

In a pinch I order from

Discount fleet supply.

I tested a eco pur on a high milage engine about 300k. Oil samples always looked good. Had to replace pan for rust. Had a inch of oil sludge in the bottom. Its no longer on the truck and back to 10k oil changes.

Used Eco Pur forsale cheap.

 

That has changed a lot over the years. When I started with a company they did 8,000 mile oil changes. Then the big Luberfiner LF750B filters came on new trucks. They changed to a dry service at 8.000 and an oil change at 16,000. That was extended.
The first small bypass filters I remember were Cummins with the 777. It is the same size as the full flow 670 and they were side by side under the oil cooler. Companies started going to 20,000 miles. I have seen this same oil filter set up on Cats with the single 4005. Detroits with the duel B95's or 2160's. Then Detroit discontinued that for only 2 - 2160's.
Then the spinners came out in about 88 and at least one company went to 25,000 mile intervals. Those had a replaceable paper in them. The amount of sludge trapped in the the outside would have to be seen to believe.
Cummings replaced the twin spin ons for a single LF3000. One does it all and interval is the same? I own a 89 IHC Cummings with the 777 capped off on the oil cooler and a spinner on the frame rail. Apparently someone believes in them. I have not researched everything about all these filters as in the Cat and Detroit in order to make a recommendation.
Motor oils have changed and improved as well. JD changed their recommendations from 250 hr to 500 with JD filters and their Plus 50 II oil. The single paper looking filler is a cartridge. No little spinner or double filter hid in that. Company went to that program on three large tractors with over 10,000 hours on each. No engine problems but the 10,000 hr grease use had issues. I hear of some trucking companies doing similar things with 30,000 mile changes but they probably plan to sell them before other issues.
So to recap more filtration is better. Cat would not have a 777 base built into their filter base assy on extreme duty engines if they did not agree. A 777 or spinner type frame mounted filter is not a bad idea if you are in this truck for the long run.
There is lot of hype out there these days that oil does not wear out. That is not new. I was told Grayhounds oil slobering Detroits oil never got thrown out. At service time it was pumped through some big heated sock filter deal and pumped back in the engine. Additives were added for that amount of oil and it was topped off with new oil. They were kind of self changing anyway. ( Excuse the side track and it is hear say anyway ).
I could debate my believe but will end with this. Most engines begin to consume more oil after some time after an oil change. I could name several examples but just one was a Cat. It used no oil for about 10,000 miles and then would use a gallon every 1,000 miles. They did not change oil before 20,000 miles. This was the drivers point and I even talked to the company man about this. By the time you run it on 20,000 mile changes you have already bought another 10 gallons of oil on the road. Why don't you just spend a couple extra dollars on a filter and change it at 10 or 12? NO IT DOES NOT NEED A OIL CHANGE! Well if it starts using oil then does that not tell you sometime? Is the oil not breaking down and or contaminated? 20 + changes it was. Looked up Wix for letters on extended life filters. They have XD, XE and ecoLAST. They explain what they are and the financial savings for large fleets. I am sure other companies have similar products. As for me and my family we like to dump that stuff out as we usually keep things a long time.
ROLLIN COAL: I know that was long but understand you take better care of your rig than most folks from your posts. Just sharing to the best of my understanding in my odd way.
