Oil Filter Question...

anbran · Post by **anbran** » 30 Jun 2011, 06:50

I keep reading about the S/V 70's requiring the oil filter that has a "check valve" in it such as the Mann brand. I am curious what this valve is supposed to accomplish if the oil filter remains full of oil while its upside down?! I could understand a check valve for a filter that is on its side...but...

Could someone clarify...

Thanks

It holds oil pressure up until the oil pump can suck it up from the pan and builds up pressure at a cold start.

Pressure comes up quickly, but not quickly enough to prevent a little bit of valve chatter on filters without a check valve. Stick a Fram on there sometime, and you'll definitely hear the chatter.

NAPA Gold filters are a good alternative to sourcing the OEM Mann filters (although some of the NAPA stores do actually carry Mann filters).

Man I use the framm filter. I do hear some cam or valve slap when cold. What other filters do you recommend ?

What is the number of the fram filter you are talking about? Maybe a Mahle alternative will help, if you give me the year, engine size and model, along with any engine codes, I can run a check on what is best for your motor. I work in the car filtration business, so I am more that happy to help with this problem, with my knowledge and contacts, I am sure I can resolve your problem.

Kind Regards,

Don't use the Fram orange can filter...it is well known to be a very poorly made filter...especially for the ADV. The frame extra guard is a good filter. Mann, Mobile1, etc.

I just bought a case (qty: ten) of Mann filters from FCP for $39.95. A real good deal, since the cheapest AutoZone filter is an STP for $4.99.

I had a curious find today...

I was at Autozone and was just browsing, and I decided to look at the oil filters that would fit my car (cartridge style, so not necessarily relevant here). Anyway, I opened up one of the Fram filters, and was shocked to see the filter was actually a Mann filter made in Spain. I checked another box to make sure; it appears the Fram cartridge filters for Volvos are simply re-branded Manns. Those are good filters!

Now concerning the cheap Fram can filters, wouldn't touch them. Their higher end filters are great though.

My NAPA store actually have Mann filters in stock. From what I gathered, Mann or Mahle are the way to go if you want to stay with the OE stuff.

FCP case of Mahle filters is a great deal IMHO since I paid 18$ for a single Mann filter from NAPA.

The Napa gold or pro select are wix filters with check valves. They are good. I buy the Manns from FCP usually by the case.

What about the cheap supertech oil filters from Walmart? There is nobody else local to me that supplies oil filters that are no FRAM. I just did an oil change and I still have some chatter.
