change in mazda oem filter

[shDK]

Hallo all

Just today i bought a new oil filter for my 2008 mazda 6 with a 1.8 mzr engine. i bought at a mazda dealer. the mzr engines is likely not sold in the US. but as 2.0 and 2.5 instead

the last time bought a filter, at the same dealer. They gave me a filter with the
part number. lf10 14 302 9a . that one had no ADBV witch make sense since the filter is mounted horizontal.

today they gave a filter with the part number lf10 14 302 9b. a small change in the number, but now suddenly the new type has a ADBV.

i made the dealer double check the number, and it is what mazda spec. also the change in the last letter from A to B makes is sound to me that it supersedes the old number.

however. does anyone here have an idea if the engine might have a problem with a ADBV in the filter it probably was not designed for. might the old type be better for the engine? what do you BITOG,ers think?

thanks
Søren

It's probably better if it has the ADBV with the filter being horizontal. Probably why they made the change.

 

[shDK]

Sorry. I wrote wrong. It is NOT horizontal is is vertical. My translation from Danish to English was wrong

I'm asuming you mean verticle, thread end up.

Can't think of one issue with having a filter adbv even if not specifically spec'd for that engine.

Been discussed here recently with a Fram that had none, but the equivalent Puro and Wix applications both have one.

No worries with the adbv, won't hurt.

Filter orientation would not make the adbv irrelevant. Having filter below sump level would. ADBV is check valve and is NOT orientation specicfic though at top of engine and base down will empty overnight regardless of having ADBV - e.g.: our 2011 SUBARU fORESTER WITH the FB25 engine

Mazda did a revision on that part, hence the "B" at the end of the part number. If Mazda's parts system says this is not the new part number for your car then I'd believe them and wouldn't worry about using it. The addition of an ADBV will not hurt anything, it can just help out.

You Are right. I am sorry for my bad spelling.

But Will The valve effect the oilpressure in any way when running ?

 

[Quest]

ADBV on a typical automotive engine oil filter will only opens under 2 most common conditions--the filter media experience restrictive flow (meaning that pressure difference is high between the 2 ends).

(a) filter media is severely clogged, which ADBV valve will open (bypass mode) so as to allow lubrication to work.

(b) severely thickened oil. This happened in the past with some high viscosity oil used in severe cold winter weather (oil got too thick on the media side, causing the ADBV valve to go into "bypass" mode.

Unless you are experiencing this said problems, otherwise, ADBV valve or not shouldn't be too much of a concern (IMO).

Q.

 

[Sayjac]

Zee can comment further on oil pressure, but an adbv is just a one way check valve designed to keep oil in the filter and the oil galleries on engine shut down. Having an extra one, (one where not specifically specified) would have no relation to a change in oil pressure.

I'm thinking if like the Fram vs Purolator/Wix example I noted above, like Puro/wix, Mazda may have combined your no adbv application with ones that did specify an adbv (just speculating). You just now have an extra margin of safety against dry start, start up rattle.

You are thinking of the BYPASS valve, not the ADBV.

The ADBV opens any time the engine is running and oil is flowing through the oil filter.

The BYPASS valve only opens when there is a pressure difference (ie, delta-p, or aka PSID) across the media that is higher then the bypass valve is set to.

The ADBV will NOT effect oil pressure. It's a soft rubber "flap" that acts like a check valve. It takes practically no pressure to make it open up. Besides, with a positive displacement oil pump the ADBV has near zero effect on the pump's performance.

Don't worry about it ... just use the oil filter that Mazda themselves have specified for this vehicle.

 

[Quest]

You are right, Zee, my bad on the ADBV valve part (keeps thinking about drainback valve).

Why does original oil filters (130, 160, 15A) for newest FB20/ FB25 have ADBV? I guess, filters without ADBV may be cheaper, but there is still existing of ADBV...

p.s. Oil filter of FB20/FB25 is located vertically on the top of engine...

 

[shDK]

Changed the oilfilter to the new type. And filled up with the same valvoline synpower 5w30 FE I have used for the last 12.000 km. And I have not noticed any difference. yesterday I had a feeling it was a bit more noisy at idlle. But not today. So no difference here I think.

You have not noticed...
You think...
You had a feeling...

But you are not an engine...
And wear of your engine can not be measured by ear.

Your right.. unfortunately I dident have the time to take the engine appart. Measure wear, drive another 100.000 km and then take it apart again. So for now. All I can do is to listen for new sounds.

 

[RF Overlord]

I say the sounds you hear are due to the infamous "power of suggestion". You're concerned about the presence of an ADBV where none existed previously, so you're being more critical in your listening. Stop worrying and enjoy the car.

Actually shDK, you spelled it correctly: "vertical".

You Are Probertly right

 

[Sayjac]

The OP did spell vertical correctly. However the point was, vertical can be either thread/base end up or thread/base end down.

And it doesn't change the appropriate answer that an adbv, even on an engine not originally specified for one in (most likely thread end up) the filter, will make no difference to that application on said engine. Add that to the fact that Mazda OEM added it, confirms that fact.

The ear is a very important engine diagnostic tool and not to be dismissed so casually. Of course you must have somewhat of a trained ear - though the car's regular driver should be wary of any "new" and different nasty racket and is qualified to some extent to make an assesment. I ignored a racket in and old Audi 100ls of mine by turning the radio up and the engine exploded on the highway a few minuted later raising the bonnet and blowing white smoke and oil vapour to the extent I could not see forward!
FMA Inspection showed the poor puppy (mercedes tractor pushrod engine) threw two rods through a gaping hole in the block. Maybe that is what's meant by a pushrod engine
