Mobil 1 oil filter vs Mopar Viper spec

[Invasivore]

I used a Mobil 1 filter for my first oil change with this car. I was wondering how it compares to the Mopar Viper spec filter in a technical aspect. Bypass pressure, etc....

BTW, my car sees 75psi of oil pressure at operating temp with Mobil 1 10w-30, not sure if that is normal

Plenty of threads on this. I did some research, and quality and construction were not substantiated by request to Mopar. In other words, the data says BS, and when confronted with a request for specs, like a white paper or something, crickets.

I use the M1-204 as do many others. If Mopar wants to offer the data to support their claim, I will listen. But for now, their bluff has been called and they have not responded. I call BS.

 

[Invasivore]

Yeah, i couldnt find any concrete info on what makes Mopar's filter so called "viper spec"

Why take a chance? Are you willing to bet your engine that saving a couple bucks is ok? Why not use the genuine parts?

 

[Red Snake]

I believe I read that there is some kind of check valve in the Mopar filter that is not present in the aftermarket ones. And that is supposed to be why you should use the Mopar one. Not positive though, maybe someone who knows for sure can comment.

Judging by the facts, or lack thereof, on filter construction, the "genuine" part could very well be the chance you take. And saving a few bucks? The M1-204 is actually more expensive than the um... genuine part.

The NAPA Gold filter is from Wix, and Wix makes the Mopar filter.

NAPA usually has them on sale a couple times a year.

I was using the Mobil-1 filter for a while, ......now I'm only using the Mopar filter. It costs a little less, and it says Viper right on it.-way cool

this. why not just run the spec filter for it? is it that hard to swing by the dealer and pick it up?

 

[Brian GTS]

I use OEM filters but have been tempted to use Mobile 1's....only because when the local stores run their 5qt special, they include the filter "free"!

Go ahead, do some of your own research. Cut them both open. Only takes a couple minutes, measure wall thickness of the can, the bypass spring inside, filter media, etc. Post your results here!

I don't need to do any research. I figure the millions of dollars they pay their engineers is good enough for me. I'll just stick with the originals.

This filter topic has been beaten many many times on this forums and others that I frequent. There is actually a lot of good info out there. Specifics on the factory spec filter? Don't know.

+1 i have replaced many motors that got no oil pressure and had a Fram on it.

I've cut them apart. M1 Napa gold and the oem viper. After that I now use the oem viper filter. I can post pictures if you like. May take a day or so to get it done though. The oem has more filter area and has the special valve that is spoke of above.

What is this part number for this filter? I have always just grab the mopar filter on the self at orileys

Yes, please. That would be great to see! Thank you.

With Venom one can order from VPA at less that I can but aftermarket stuff for. And it shows up to my door with the other parts I got so it is basically free shipping.

And I know the Mopar filter will work.


As for difference, has to do with bypass pressure for WOT I was told.

I was doing the same thing for years, after all, for a while the 090 filter was all there was and was put in GEN1's and early Gen2's from the factory. The 090 shelf filter works just fine. But I started using 15W/50 for the track per Dick Winkles and he said I should start using either the updated Viper Mopar or the Mobile 1 filter for track use, but that for everyday use the 090 filter was just fine.

I did notice that with 15w/50 and the Mobile 1 filter my oil pressure went up 10 to 20psi.

WOT on a yellow Viper, that made me laugh. Thanks Robert!

Mine (2001 RT/10, stock) is about 55 psi using Mobil1 0w-40 and either the NAPA Gold filter or the Viper filter.

I always ran K&N oil filters on my Gts and still run them on my SRT10 I have been to the K&N factory and they spend lots of money and time researching and testing the filters. It also has a nice bolt head on the end which makes removal very easy. Never have experienced any problems on my Gts and I used to track it quite often. My SRT 06 continues to have them on there. Just because it's got Mopar or it's OEM does not mean its the best that is for sure. IMO

I'm also in the MOPAR SRT filter camp. As it has already been mentioned, this topic has been covered in prevoius threads.
The new SRT filter is designed to run in the Viper's operational oil pressure range. If you actually own a Viper, in my case a Gen IV, then you know the oil pressure generated by the V10. At cold startup the oil pressure pegs out around 100 psi and at operational temperature it's in the 70-75 psi range. The aftermarket filters apply to a much wider range of engines and do not have the burst strength or the proper bypass valve pressure calibration for the Viper engine. Will they work in a pinch? Yes, but your risk blowing out the filter on a cold start and/or unfiltered oil being fed to your bearings due to the aftermarket filter going into bypass prematurely. It's not worth the small amount of savings on the filter if you ask me.

The following is what the engineers had to say about it in one of our VCA/SRT Chat sessions: (Sept 9th 2009 )

FastZilla asked: "What are the differences between the "specially developed" "SRT" oil filter and the high quality after market offerings of Mobile 1, K&N, etc.

I have read posts that mention:
- filter housing thickness
- stronger bypass springs
- neoprene anti-back flow valve
- 3 ounces heavier than previous Mopar filter
- coarser filter media vs super-fine K&N (and the like)

There are tons of us here that really want and need to know the secret behind the "SRT" filter. I literally am losing sleep over it - I can't accept the SRT filter's superiority on a leap of faith.

We all want the very best for our Vipers - please help us understand the SRT filter.

Thanks in advance!"

The SRT oil filter for all the past engines and the new 22mm inlet SRT filter for the Gen 4 and beyond engines share the same characteristics.
We worked with many of the filter suppliers to get the best features. Some fell out for various performance reasons but we ended up developing the current SRT filters with one of the mainstream manufacturers (it is different than their commercial offerings - or at least was when we developed it). The high flow oil pumps in our large engines (Viper is the biggest) can overpower the internal relief valve. When this valve opens it allows some of the high pressure dirty oil to bypass the filter element in order to keep the filter from being damaged. The SRT filters do indeed have a higher differential bypass valve to make sure all the oil delivered to your powerplant is clean. The housing is slightly thicker than many of the brands out there to handle the pressure but is not the thickest. The real thick ones failed our development testing (fractured at the crimped flange). The media used was one of the latest synthetics that allowed very fine filtration, more debris capacity, and much lower restriction than our standard Mopar filter (and just about every other filter out there). The final result was clean oil to your Snake, all the time, with more pressure to the internals where it is needed. I would fully recommend using this filter in your beast, I do in mine. Hope this info helps. KCC

I used a Purolater Pure One two oil changes ago, excellent filter. Oil pressure was the same as the Viper spec filter (40-60 PSI on my car). I went back to the Viper spec filter on the last oil change, its only $6 more plus shipping. The case is definatley stronger (couldn't even slightly push in the metal case with both hands). Looking inside the filter, you can see there is a unique bypass valve design. Would love to see one cut open.

 

[dave6666]

From an engineering perspective...

Going to a thicker oil and seeing more oil pressure can be an illusion of improvement. Pressure is caused by resistance to flow, but before I go too much further, I'd like to point out that since the oil pump is a positive displacement pump, that the relationship between the flow of oil A to oil B, is somewhat equalized by that fact. Back to pressure and flow, as the pressure is higher, the thicker oil could be actually flowing less due to more resistance of trying to get through the journals. An adequate flow of oil is important, whatever that volume may be.

On to the positive displacement nature of the oil pump. it will move the same amount of oil with each revolution. Minus internal losses from clearances. Thicker oil could bypass more inside the pump due to the increase pressure at the pump outlet. Therefore, thicker oil could be of a lesser flow volume. Depends on the physics of the oil to the pump etc. I've never tested it so don't ask. Anyway, the thicker oil definitely takes more horsepower to pump. So less power at the flywheel.

Some of this flow to pressure relationship depends too on the layout of the journals in regards to pressure relief valves and where the sensor is. If the sensor is right at the pump versus at the last journal, two very different meanings of the increased pressure. Also, some engines have one or more relief valves in the oiling system. This can effect what the pressure really means when you go to a thicker oil and see more pressure. If it has relief valves at both ends of the oiling system, you may dump excess pressure (and flow volume) at the first journal, but the pressure down the crank reads good because of a relief valve at the end to keep the flow passages pressured up. All depends on the layout and design.

On to filters, flow and pressure, if there is an internal relief valve that has a higher pressure setting between filter A and filter B, you are subjecting the filter media to this increased pressure by this change. Most filter media. especially a simple paper or fiber type, will have a point where it will either fail mechanically, or allow more particles through as the pressure against it goes up. So has the tradeoff been quantified and studied? The possibility of unfiltered oil during a warm up period, versus the possibility that the particle entrapment has been overcome?

I have no problem with SRT saying they have a better filter. But I asked a few questions, raised some concerns, that no one has ever addressed or answered. Go technical on me SRT. I can handle it.

 

[Got_Vnum]

Dave brings up an excellent point. Increased pressure is increased restriction to flow, not an increase in volume of flow.

Dave - Can you share with us what specific concerns you brought up that were not addressed?

Ok, here are some pictures of the Viper filter cut apart. The steel housing is 0.022 thick.
