I'm curious where you obtained your relief valve (RV) setting value (23psi) and to which specific OE filter(s) you are referring? (AM Models, engines etc)

This info seems to be closely guarded and the only reference I have found to AM oil filter RV values is from an old AMOC thread where a few owners were trying to find a non OE replacement for the AM oil filter for the v12 and sent one to Wix for testing - A member (DWR46) reported that the filter examined had a bypass RV setting at 23psi. However, that's a different oil filter and engine to the AMv8, and likely flow rate. Later in the thread he reported that he believed Wix hadn't really examined the Aston Martin filter he had sent them, bringing question to the actual bypass relief specification of 23psi he reported in the thread's first post. The net result of that thorough investigation by several AMOC members however was that the Ford Racing CM-6731-FL820 Oil Filter was possibly a superior option over OE for their Aston v12. The correct RV for that AMv12 was never substantiated.

Donaldson makes the oil filters for AMv8 (and more) at their plant in Mexico. It appears though that the only auto market full flow spin on oil filter made at that facility with a 23psi bypass relief setting and similar other physical specification is manufactured for Peugeot. If you have more oil filter specifications for the AMv8 please share.

The AMOC thread I referred to determined that AM contracted Donaldson to make their filters in Mexico (2013) - they have similar pics with the AM logo and the filters are stamped Made in Mexico - perhaps only the v12 is made in Mexico. Pics are here:

My main question is where did the 23 psi value come from for the Amv8 ?

Edit: Donaldson have plants all over the world BTW.

I cant open any of the two pic links you guys have added (my PC has a small virus at the moment because I have been on some interesting web sites) Please can you post the model and make number for the V8 Vantage filter? so i dont have to pay R2000 for a 200 Rand part here in Cape Town

 

Look up oil filter for 2006 Jaguar XK8; 4.2L engine
Many to choose from that should fit.
MOTORCRAFT FL2021 is OEM Ford and should work according to listings at rockauto dot com.
I'm using the Fram PH9010 but they are becoming increasingly difficult to find.

Hi Don,

I'm not trying to disagree with you but moreso trying to figure out where this thread came up with an RV value at 23psi.

In regard to the use of Ford or Jaguar filters you specified, a quick check and the Ford filters wouldn't meet the specification that was posted earlier in this thread about Bypass Relief Value. - which is why I want to know where it came from for the AMv8?

Source: Summit Racing

Product | RV Pressure Valve | Anti-Drain Back Valve
MOTORCRAFT FL2021 None No
MOTORCRAFT FL500S 8psi Yes
MOTORCRAFT FL820S 16psi Yes

Not saying you haven't had success with these or Jaguar filters - you may have and one or more of them may actually be closer to the real specification of the AMv8 oil filter but not according to the info previously stated in this thread. (Except perhaps the FL2021 - as it has neither a Relief Pressure valve nor an anti drain back valve - both are known AMv8 oil fllter characteristics)

What this thread needs is the actual tech specs of the OE AMv8 filter - (I.e. number of pleats, composition material, RV High and Low values, etc etc. then a cross reference can compare the same values and not simply dimensions. I thought I had it nailed (the OE filter from source at non AM price) till I saw 23 psi in this thread. I still may have - I think the 23 psi as stated is wrong, if it's not there nary a Jag, Ford or other filter outside the racing realm that will meet spec.

 

All this talk about bypass valve pressure and filter specs materials blah blah blah is all good however ...Dollars to donuts anyone on here who changes their own oil does it far more often than actually needed so the chances of filters being blocked or restricted is minimal so the bypass valve pressure and filter material etc is really a non issue .
I use the Castrol liquid gold 10W60 in my Vantage and the Fram PH9010 . I have put less than a 1000 miles on my car this summer but it will still get an oil change over the winter regardless . Its cheap insurance . Same story with her Z4 .... minimal mileage but will still get a lube job as well .

 

Just to play devil's advocate, wouldn't spending the extra few dollars on an OEM filter that you know suits the engine and its oil system be "cheap insurance" as well?

 

Nothing to do with the frequency of changes at all - quite the contrary.

The RV value is not a non issue if indeed it is what was stated (23 psi) which is why I want to know where this came from. It would mean that if you put your Fram filter in at 7psi RV and are using a 10w60 weight oil, every time you start a cold engine for a considerable period of time till your oil heats and thins most of it may be by-passing your filter.

If that's not an issue worth finding out about then I'm not sure what would be? Using an oil filter without the anti-drain back valve is also risky.

I change oil/filter every 5k (kms) - I sourced what I believed to be the exact AMv8 filter less the price - it is not 23psi - You might not care about non filtered oil and engine wear but I do - that's why I want to know where this spec came from.

 

But then why have a forum - Why even do DIY - just drop it off at the dealer. The point is actually finding out the spec. so we can properly maintain our cars. There is no doubt in my mind that the oil filter is a common oil filter used on a multitude of Ford, Jaguar and other vehicles. - Like a wide variety of replacement parts on this car (well my AMv8) anyway - most of it is borrowed from other cars or trucks.

Even if the AM dealer here didn't act like a jackass, thinking his products were made from Unicorn Tears, I still wouldn't buy the same filter for $50 that comes with a different label from the same source for $8 at my part supplier.

I see you sell the oil filters. As a supplier I have a customer question - what is the RV setting of the filters you sell for the AMv8?

 

I don't know what it's actually rated at. I approached several filter manufacturers asking them to basically reverse engineer the OEM filters. I planned to offer my own with the same specs at a lower price, or even with improvements if feasible (better filtration, etc). Only a few were interested, but those each came back requiring a $50-100k investment. It was entirely cost prohibitive, so I got a supplier for OEM filters. I was going to develop private label parts for other stuff, too, but sticking with OEM ensures factory quality and I can still offer those parts at a much lower price than dealerships. I do replace parts as I see fit, though.

My first oil change when I bought my car done by a dealership. They charged me $650. I now offer everything needed for less than $200, and have step by step guides (and videos) showing how to do the job yourself. Yes, it's still an expensive oil filter compared to an $8 Pep Boys unit. But total cost for an oil change is less than a third the price a dealership would charge.

I've spent countless hours helping out the Aston owners community on this forum and I started Redpants because people kept coming to me for more. But I pick and choose my battles. I spent a lot of time on oil filters and decided the OEM filters at a more reasonable price point was the best option.

 

Not being a dick Rich but you do have a vested interest in selling AM parts however having checked the link to your oil filters the price is way more realistic than checking other suppliers and fleabay etc so maybe I will become a customer .

 

I wasn't trying to be a dick, either I asked purely for the sake of the conversation. I have a bit of a vested interest, yes, but your answer to that question is just as important. It would help me better understand why other owners are using non-OEM filters. What makes a risk worth taking? Or is there no perceived risk? What determines whether an owner will use an OEM filter or an aftermarket one?

 

OEM versus non-OEM . Simple cost ...its a filter not rocket science and as I said if you change your oil more than regularly as I do then I really dont care if the filter is white ,black ,orange ,purple ,pink with polka dots or has a fancy wings logo on it that no one sees . Its a filter and those fancy black or white ones with the wings logo on are probably just repainted Fram or Bosch or whoevers filters with a jacked up price .

 

Source quoted below indicates the FL2012 has both a relief valve and a anti-drain back valve.
I guess the only way to tell is to purchase one and "dissect it" and inspect.

At the time the Jaguar engines in question were being made, Ford owned both Jaguar and Aston Martin.
I'm curious which filter you have chosen?

Here are the specs for the WIX 57302 ($7) which has both a relief valve (@16 PSI) and the anti-drain back valve.

As to the question as why does one choose an aftermarket filter...Convenience and price.
If I can source a filter at my local auto parts store, at a lower price, it's a win/win situation.
And I have the luxury of now having an AM dealer 7 miles from home (thanks to Tim also!).
And I don't perceive a risk using a reputable manufacturer...
