Went to Auto-Zone today for a few things and was going to pick up a few filters. Opened the filter book and lo and behold there was a number for the M-1 filter for the DMAX!!! They actually had 1 in stock for $9.99 so I grabbed one to try it out. The number is M1-303. I seem to recall people on here wishing that Mobil would put out there filter for the DMAX so I guess we got our wish.

I have been running one for about a week now. Will let you all know how it stacks up!

Running it with Rotella T 15w-40 dino.

As previously discussed, the Mobil 1 filter really is exceptional. A synthetic filter enabling excellent filtration down to 10 microns plus a much larger dirt capacity than regular cellulose.
Really is a quality filter.. Especially in cold flow situations where the synthetic blend is much less affected by sub-freezeing temps than a pure cellulose. One went on my Duramax the day they came out..
AC's are good but this one is certainly superior in every parameter.

Where can you pick one of these babies up at? www.avlube.com (http://www.avlube.com)?


Ben

Unfortunately, no, the Mobil 1 oil filters not available at www.avlube.com.
The reason is: Autozone, Pep Boys sell filters for less than we as distributors can purchase them from Mobil! Not to go into the gory details but those Autozone/Pep Boys/WalMart shelves are very sacred and some oil companies actually pay retailers for space; falls under the heading of 'advertising'...
We only carry items at www.avlube.com that are reasonably priced or not readily available from Autozone, WalMart, etc.. We certainly wish we could have them available on our web site for a reasonable delivered price but....
Thank you for asking tho...

Good to see that these finally came out for the Dmax. I currently run Baldwin but these may change my mind if any will. http://www.dieselplace.com/forum/smileys/Thumbs Up.gif

I wonder how these Mobil 1 filters compare to the baldwin B1441 in terms of efficency versus particle size--Currently I can purchase the baldwin for $5.00 per filter.

Anyone know where to get these in S.E. Wisconsin? I am needing more filters. This will be the filter I will buy! SPICER

Are M1 filters compatible with regular dino erl or are they only meant for use with synthetic?


Thanks,

I just called the "Mobil-1 Filter hotline" to find out the Beta Specs for the new filter M1-303 filter. The person on the phone didn't have the Beta spec data. I asked how I could get this info and he referred me to the "Regional Rep" whom I called and left a message. I also sent them an email asking for the same info… If I get a response I'll post the data… It will be interesting to see how their specs compare to the Baldwin B1441 (8 micron nominal, 23 micron absolute), which I believe also uses a synthetic blend media.

Thanks Bill, This would be great info.

Just got a call back from a Champion Labs rep..

It turns out the M1-303 is made by Champion Laboratories (http://www.champlabs.com). The person who retuned my call gave me the name and number of their technical guy whom he said could answer my questions. He's out today but will be in tommorow. I'll give him a call then and post what I find...

I believe Champion Labs also makes AC Delco filters including the Ultraguard Gold (http://www.acdelco.com/html/pi_filt_oil_gold_single.htm) which is an excelent filter: 98% efficient at 8-10 microns. (I use the Ultragold UPF-52's in my Impala's 3.4 V6)

http://www.dieselplace.com/forum/smileys/Geek.gif

Great news! We should be getting those here in the Gainesville area by 2007.http://www.dieselplace.com/forum/smileys/Angry.gif

Re: beta specs.. I do not think you will find these numbers; wish they were available, however..
The ASTM procedures are for hydraulics and auto/truck filter manufacturers have not been 'pushed' into that arena of actually publishing performance specifics as per the ASTM filter procedures..
Reason: there would be some pretty horrible looking numbers out there!
Even in the case of the Mobil 1 filter, no Beta X200 numbers posted...
So, until a manufacturer finally breaks the dam for real performance numbers, we will just continue to get meaningful information via TV ads of "you can pays me now or pays me later"....

I just got off the phone with Brent Birch at Champion Labs (http://www.champlabs.com) and he quoted me the following specs for the new Mobil-1 M1-303 oil filter for the Duramax.

Nominal efficiency: 5 microns (Beta=2, 50%)
Absolute efficiency: 18 microns (Beta=75, 98.7%)

Excellent!! http://www.dieselplace.com/forum/smileys/Clap.gif

I believe the M1-303 takes the lead over the Baldwin B1441, which is specified at 8 microns nominal, and 23 microns, absolute. Brent did say that Baldwin's specs were also very good for a full flow filter.

I asked Bret if they would be publishing these specs and he wasn't sure since Mobil handles the marketing. He did that they do publish SAE 806 specs for the PH8 version of the filter but this test doesn't specify efficiency in terms of microns.

Well, if I didn't have nearly full case of B1441's on the shelf and an OilGuard Bypass filter on my truck, I would be immediately switching to the M1-303.

http://www.dieselplace.com/forum/smileys/Geek.gif Edited by: jbplock

Bill,


Why the flip in efficency? Mobil 1 efficency is exactly flipped from the Baldwin.


If my brain is screwed on right, the largest particle to get caught is the absolute, where the nominal is the "normal" or 95% of the time partical size that filters through.


Just seems odd...http://www.dieselplace.com/forum/smileys/Geek.gif

You are correct; methinks there was a mis-type with the Mobil 1 filter specs.
Numbers are reversed...
And I will be darned!! Congrats on getting numbers.. However, would have been better to have real beta ratios quoted.
There is really no such term as "nominal" and "absolute".. These are ad jargons, however, the percentages and size do give us some guidelines.
Thanks again for pursing..
George Morrison, STLE CLS

OOPs! http://www.dieselplace.com/forum/smileys/Embarrased.gif Good catch ... Yes I reversed the nominal and absolute numbers... It's fixed

M1-303 is 5 micron nominal and 18 micron absolute...

http://www.dieselplace.com/forum/smileys/Geek.gif

Can you explain Beta Numbers then Professor Goerge? Inquiring minds want to learn.


TIA.

George,

Thanks for clarifying this! http://www.dieselplace.com/forum/smileys/Approve.gif I'm also curious about the beta ratios (??) Brent quoted me Beta ratios of 2 (50%) and 75 (98.7%) for the 5 and 18-micron efficiency numbers respectively. Are there other ratios? My limited understanding of this is based on reading the Baldwin Paper Filter Perfomance and Micron Ratings. (http://www.baldwinfilters.com/engineer/95_11.html)

These are the equations from the paper...

BigdaddyG - Thanks for posting the info about the Mobil 1 availability. Nice to have a premium filter available at the local parts store.


jbplock - Appreciate you taking the time to run down the numbers. Had been using the Baldwin B1441 up too this point (as a result of the numbers you posted previously on TDP for the Baldwin). Got one more to use up then I'll switch to the Mobil 1 filters which are available locally.

Good info thanks.


Guess I'm going to call my Mobil dist. and see if he will stock.





Mac http://www.dieselplace.com/forum/smileys/Approve.gif

I ordered two M1-303 filters from autozone.com after reading this post Sunday night. Free shipping even! Then today I get an email from Autozone saying that they are sold out & back-ordered, so they cancelled my order.http://www.dieselplace.com/forum/smileys/Angry.gif Must be a pretty popular item.

I apologize, I missed the beta references for the Mobil 1 filters..
However, even tho the term 'absolute' is not used in filter ratings, generally a beta 200 ratio is considered 'absolute'..
So, the use of a beta ratio of 75 is still a little low relative to the norm.
As there are no such terms used as ASTM definitions I am splitting non existent hairs...
George Morrison

I have always been a big fan of the Mobil 1 filters and the K&N Performance Gold filters. K&N also makes an oil filter for our Duramax's. Part # HP-3003. Anyone have any numbers for this? How about personal preferrences and/or .02 cents worth? http://www.dieselplace.com/forum/smileys/Big Smile.gif


Thanks, Jeff

What are you guys paying?


Mac

good point ace high i also would like to see a comparison on the k&n and the mobil 1 i run ams oil 15-40 synthetic and stock gm filter.

I just purchased my K&N filter last night for $10.99. I didn't know Mobile 1 filters were available when I picked it up. I still have another 2,000 miles to go before my oil change, I just happened to see it on the shelf and I grabbed it. If Mobile 1 has better numbers then K&N I will return it and get the Mobile 1. But for now, I will just hold on to it because it was the only one on the shelf.


Jeff

I ordered 4 from Murray's yesterday, I had them first thing this am and I'm already running one ! http://www.dieselplace.com/forum/smileys/Clap.gifhttp://www.dieselplace.com/forum/smileys/Cool.gif $10.99 ea.

Anyone know where to get these in S.E. Wisconsin? I am needing more filters. This will be the filter I will buy! SPICER


Spicer, My daughter works in Waukesha, and she was headed to the AutoZone on Sunset, so I had her check out that Mobil1-303 oil filter. They only had one in stock, so she picked it up for me @ $9.99. I'll check the other stores as I go by them to see if they carry them as well. How about a heads up if you see them elsewhere. As info, this is from the side of the box:


"This Mobil 1 filter element features a synthetic fiber content that gives it one of the highest single-pass efficiency ratings available, with 98% particle removal at 10 to 20 microns. Multiple pass tests using SAE procedure J806 show Mobil 1 oil filters are 95% efficient in removing harmful contaminants from engine oil (conventional filters average 80% efficient)."

Thank You. I will call Auto-Zone today to check on availability. SPICER

Spicer,


There is a Mobil Lubricants distributor in Kenosha just past the exit for Union Grove Dragaway(HWY KR) on the east side of the expressway. I recently bought 6gal of Mobil1 synthetic ATF for $100 even. 6qt. cases of Mobil1 5W30 are $17 as upposed to $24+ everywhere else(I use it in my gasser). Don't know about the cost of the Delvac or Delvac1. But I am sure they will have the filter cheaper than anywhere else. They only take cash/check, NO CREDIT CARDS.


number is........................(???)859-2831 or (???)552-9070

As I had indicated in a previous post, most Mobil distributors do not carry Mobil 1 oil filters, as retail outlets such as Autozone, Pep Boys, etc. sell the filters at prices below what a distributor can BUY them for, much less sell and make profit..
Part of mass merchandising 101, unfortunately.. Some oil companies actually *pay* retailers for significant shelf space locations..
George Morrison

Wow... interesting George. Never knew that aspect of marketing. Give away merchandise to take space away from your (not you) competitor.Edited by: hoot

Arlen,


The autozone on main street in the Falls (across from Piggly Wiggly)has one of the shelf. I left it there for you since I just changed oil, I still have a Baldwin left. So go get it.


Oh, btw I don't know how backed up you are with your tree service, but I've a got a large dead one that needs to come down either this fall or maybe the spring if you're booked up. If you get a chance I'd sure appreciate a quote.

Rick,


We will talk. I need my tranny flushed and need a hand with that. September is looking good. SPICER

Talked to a clerk at the local Auto Zone in Mt. CLemens, MI as they only had one M1-303 on the shelf. She looked on her computer and said that all the local Auto Zone stores only have one (1) in stock as they just came avail in July. She said she could special order at the same price of $9.99 and get as many as I wanted within a week.

Problem is - She doesn't have a listing for 2005 MY (LLY).

Can anyone tell me if the oil filter for the LLY is the same as the LB7?? Not just for the Mobil but also AC Delco & Baldwin filters?? Truck is new and I want a little less expensive filter for the first few frequent mile oil changes until going to synthetic.

Thanks!

...Truck is new and I want a little less expensive filter for the first few frequent mile oil changes until going to synthetic...


Pretty sure the LLY filters are the same as LB7..


Also, depending on how frequently you plan to change your oil the first few times you could skip some filter changes. I did my first change at 1k miles and put on a Balwin B1441. I skipped the filter at the 2k change and at 3k I put in synthetic oil with a new B1441....I've been changing approx every 5k since. (Also installed an OilGuard Bypass at 5k)


http://www.dieselplace.com/forum/smileys/Geek.gifEdited by: jbplock

jbplock,

good idea - thanks for the info!

I went to Auto Zone today and got M1-303 and one for my wifes Blazer. Mine were more expensive though....$11.95 ea. Only one on the shelf.


I have an Oilguard bypass so it probably won't make a difference with my truck. The Oilguard bypass filters to 1 micron nominal/ 3 micron absolute. The Mobil1 filter will make a difference for those without a bypass system. SPICER

http://www.dieselplace.com/forum/smileys/Geek.gifEdited by: jbplock Thanks for the research everyone! As soon as my '05 Silverado 2500HD arrives I will be set.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>

<o:p></o:p>

As for oil filter changes - I have owned numerous high performance cars as well as the average grocery wagon and would not recommend changing the filter every other oil change. This is especially important during the initial break in of the engine. These filters are designed to remove more sediment from the oil and will become dirty just as quickly as any other filter. The cost of a 10.00 dollar filter is less than the cost of bearing damage.
