oil filters

If an oil filter is the same size and has the same threads is it compatible with another one. I am talking about a John Deere ride-on with 12.5 hp Kohler engine and a polaris 4 wheeler I have. I found some at walmart that will fit. What other variables are there? Do all oil filters flow oil in the same direction, do any have check valve or different flow paths.....Thanks

The diameter of the sealing ring on the face of the filter. Some filters have a pressure relief valve, to allow oil flow if the filter becomes completely clogged, some do not.

Having said all that I did exactly what you did - found an after- market filter that fitted and used it. Three years later, no problems. Cheers,

you also need to make sure it has the same filtering capacity and flow. if there is a check valve/anti back flow valve you could have issues if it is a lower pressure.

and if it is a "Fram" filter, tape a quarter to it and toss it in the trash so when some one finds it at least they get a quarter. fram filters are specifically listed in cumins warranty as a sure fire way to void it because the have fallen into the low quality rut and are horrid now from everything ive seen (no first hand with them, but i wouldnt use them)

Filter comparison:

thread size gasket ID and OD OD and lenght of filter does it have pessure releif? does it have anti-flow back valve? (look in the outer ring of holes, if the holes are blocked this is the anti-flow back.)

I was a die hard Fram guy years ago, now I avoid them like the plauge. Read a bunch of stuff on the net about them, all bad. I have a parts washer that I added a filter adaptor to, uses a Ford filter (Fram PH-8A or equal), a Fram filter would clog in minutes, I HAD thought this was because they were really good filters, after reading what I found. I now know it's because they have much less filter paper in them than the other brands.

Thank You, Randy

That Fram filter issue was one specific filter for a Dodge truck, and after the issue was identified that filter was substantially redesigned to eliminate the problem and now has a "A" designation at the end of the part number. This doesn't mean that all Fram filters are great, just that the particular problem was resolved.

If you are using Wix, call their tech hotline. Nice guys, and they are OK with this sort of thing last time I called. I'm using Porsche filters on my RX7

And I'll echo the other sentiments on Fram. Their HD applications are probably OK, but their most popular filters were cheapened back around

1980.

Get out the books and cross the part numbers yourself. Do Not Guess, Do Not Assume. You HAVE to make sure first - there are a few filters that have a Metric thread where a NPT threaded stud on the mounting base will catch and appear to hold okay - but won't keep holding under pressure... Strip, gush, seize... Oops.

There's a Ford Filter on Chevy Engine swap that will do this - or is it the other way round? Either way, make sure you use the right one.

Consider that most equipment and car manufacturers don't want to spend a small fortune developing a custom filter element for their equipment - that's a good quarter million in R&D and Tooling expenses to build and run an assembly line that they could easily spend elsewhere.

This is where the "Common Parts Bin" comes in. They pick a stock filter design off the filter maker's shelf that meets their needs for size, size and quantity of dirt capture, and flow to work with their engine.

The only thing they might spend for is custom labelling of a run of the same standard size filters with their OEM part number stencilled on. Printing is cheap.

They may even buy the filter mounting studs or the entire filter mounting base casting premade by the filter maker. You can buy a whole lot of pre-made pieces for the cost of the machinery required to make them yourself.

if any of you can use them, I have a case of Sears branded filters that are equivalent to PH8, and no car that uses them (came from a friend) - I hate to throw them out, but I need the space..... contact me off the list via the email you find at

I'd really like to be rid of these things

Ph8 and PH8a? That goes back decades to when fram still made a half decent filter. What's sold today is just the cheapest they can get away with - CRAP.

-- A striking fact of the last two years of financial trouble is how accountability has differed in the public and private spheres. On Wall Street and across the country, decades-old firms have failed, fortunes have vanished, and some former captains of finance face jail or fines. In Washington, meanwhile, most regulators and Members of Congress remain on the job, often with enhanced power. -WSJ "Bernanke's Second Chance" 26aug09

No, it was some 4 digit part number for a Dodge / Cummins diesel cartridge filter application.

Wow! Small world... wish I needed the filters. I live just West of Westside Pavilion.

As a matter of fact, I'm off to Engler Brothers soon as I'm through catching up here..

...take my filters .........please..... (or contact me off the list via the email on my web site and say hello when you drive by)

and keep partronizing Engler's - we need to keep these family businesses around- the chains have their place, but a local family business is important - Engler's and the many others like them will know you, they will pick up and drop off at my house, so if I'm under a car and a mess I don't have to go to them, they will come to me - the chains won't do any of that.

Agreed!

And as a side note, Engler Brothers has to be the premier independent family run auto part & machine shop around. Clean, friendly know their stuff, and generally a pleasure to do business with.
