oil filter quality
 
I did not know where to post this question. What oil filter is good and what filter is poor quality? I think many people use the Mann filter but I am curious about the Mobil MI-301,Purolator L30257 and Hastings LF-517. I have read some negative things about the Mobil and Purolator filters. The stamped spring at the bottom that holds the filtering material instead of a coil spring like the Hastings has so all the oil gets filtered and doesn't get bypassed like a relief valve.

I am surprised no one has an opinion on oil filters.

Most of the opinions on oil filters for the earlier cars were expressed a decade ago. My suggestion is to do a search, or review the old threads. The favored filters are the OE and OEM, including MANN, which previously provided filters for VW. The new ones might be an issue, but check country of origin and compare.

Brands you can get easily that I like are Wix and Napa Gold. Purolator is pretty good, too.

I would stick with the OEM Mann.

I read that Wix is a brand of Mann. I wonder if it is the same filter.

It looks like Mann owns Wix and Purolator.

That doesn't mean the filters are equal in quality. I wouldn't be scared to use the Wix/ Napa gold oil filters(I use them on a lot of various equipment), but I'd avoid using a Purolator filter on my tdi unless it was a reboxed Mann or Wix filter.

Just FYI, lots of filter companies just rebox someone else's product to fill in the coverage gaps for engines that they do not make filters for. And many off brand filters or house label filters are made by one of the larger filter companies. That said, sometimes they are not the same filter as they get made to a price point to get the business. And this changes over time, as companies get taken over, bought out, etc.

I've been in the business long enough to see a lot of these changes. Wix, a popular brand over the years with many people, never made anything for a Volkswagen themselves in house. They just reboxed something else. Usually it was an OK filter, but perhaps not as good as some others. But now because Mann owns Wix, any Wix boxed filter (or Purolator filter, another Mann owned brand) for a Volkswagen will just be an actual Mann filter.

Mann makes most filtration bits for VAG products, however Purflux, Mahle, and Hengst have also supplied filters, as has the newest company UFI, which is an Italian company but it seems most of their products are made in China :rolleyes: .

I would stick with Mann. They seem to be consistently good, and have served many of us very well over the years.

If you want a lot of OF discussion, try BITOG (Bob Is The Oil Guy).

For my car I buy VW or OEM supplier to VW.

For my wife's car (2.5L) I usually buy VW or VW OEM. I went to NAPA and bought a NAPA Gold brand, made in China. Never again. Another time I went to Autozone and bought STP brand, made in Korea. I would trust a product made in Korea.

My advice: If you can, remove the filter from the box and see where it's made. If possible look for anything made in Europe and avoid China. With VW and others now having plants and suppliers from China, this is going to get a lot harder.

:rolleyes:

I remember buying a Meyle fuel filter for my car from Austin Veedub. The box had some Germany text written on it, but the filter itself was marked made in China. I was a little disappointed, but the filter service was overdue, so I used it. It also looked to be of good quality.

I like Hengst. Quality German brand. I remember a thread here showing many more pleats of filter media in a Hengst MK4 filter, than a Mann filter.

phaser December 11th, 2017 07:59

I've been using Hengst for years.

I've been looking for that thread showing the number of pleats but haven't found, it yet.
