change your own oil, part II

[theoldwizard1]

For several years, Walmart carried Motorcraft brand oil filters, which was great for me (all Ford products here). For the past 6 months or so their shelf stock has been very low.

Lately, I have seen some of the Walmart brand SuperTech and some Purolator oil filters showing up. The Purolator filters are the "standard" ones, not PurOne, but I think those are still "above average" quality.

The Pro Line filters? They are made by Purolator...

What should you see, if the filter did a good job?

What would you see if it performed poorly?

2-3 years ago. There for a while Champ and Wix were both making Acdelcos. I worked for Autozone at the time and all of our Acdelcos were Wix, while all of walmarts were champ.

Can't believe nobody's said this yet...

Heard too many horror stories with Fram... would never take that gamble with any of my engines. My allegiance lies with Wix.

Something else to consider...

If you've got the room for a larger filter, do some research and find a larger one with the same threading and gasket size.

For instance, on my Isuzu Rodeo (3.1L,) the recommended filter seems rather small for the size of the engine. Luckily, the filters for the industrial engines they make will fit perfectly. Have to special order them, but I get a larger Wix for mine.

If the filter has done it's job it should be dirty. seeing as it will be filtering out all the crap in the oil.
If it performed poorly it is be cleaner or some what dirty.

I believe your thinking is slightly off. If I'm not mistaken, oil flows from the inside of the filter to the outside. Therefore, if the outside of the filter is clean, that would mean that more of the contaminants were trapped on the inside and never made it to the outside.

good Point, I run the filter off a turbo diesel volvo on my audi to up my capacity, the thing is also as long as the fleetguards I run on my Cummins.


I use fleetguard on the truck cause they are cheap~7.50 a filter
Run Purolater on the audi as they are repackage Mann filters
Run wix on every thing else.

Thanks for reminding me - I forgot to point out that you'll need to use a little bit more oil for each change. Not much, but I should've mentioned it earlier.

You mean I have been doing it wrong by just rinsing out in water the same filter that came with my car???

[cdent]

Thanks Rayjay, my thought exactly. Used to automatically buy fram, but started having serious doubts based how the card board looked and a couple of seam failures. 'bobistheoilguy' cut through enough of the rumor merry go round for me. I'm plenty satisfied with Wix for now.

[KPSquared]

bobistheoilguy is the place to go for oil nerds with hard data. It was lots of reading lab reports on there and on powerstrokenation.com (before it's sad, corporate fueled death) that I decided there was no way in hell a FRAM product was ever coming near one of my engines again. The research on there sold me on WIX products. The NAPA here has a once a year filter sale. . .everything is 50% off. So I buy a case of oil, air, and fuel filters for everything I drive. It's a good deal and worth the wait.

I had to convince myself of this; seems illogical.

It makes more sense that the oil would filter into the filter from the outside, as that is where the most area is, so the correct answer is that the oil flows outside to inside, and the pump picks up the oil from the center hole. In almost 50 years of driving, I've never had any oil filter fail on me, or any engine that I drove/rebuilt fail as a result of any oil filter. BTW, I've used Fram for years, but have used others also.

Im going to take a guess that brand A is Fram, B is Purolator, and C is Champion labs e-core.

I believe the center hole leads to the oil galleries. The pump is pumping "dirty" oil technical.
