New Oil Filter For M8 Engine HD Service Bulletin M1510

FYI and reading pleasure.

Wonder why? More capacity would be a good thing for all oil changes ... even non M8's I would think.

So, why haven't they figured this out earlier? This is the third production year for the M8, right?

So when they designed the new M8's, they didn't measure oil flow?

By shear volume, their Nath is off.

Old 24.80 cu in. New 28.34 cu. This is based on a filter 3" (I guessed, but the diameter is the same for both. [Area = (Pi x RxR), Vol = Area x height]

So the new filter is capable of about 15% more volume, unless they are packing the filter media tighter, which would limit flow and the goal is to accommodate more flow, someone is pumping air up our skirts .

HD is not the only company doing this. Honda made the tank on the new wings smaller and since it more efficient, it is supposed to equal out .. can't remember the numbers, but, basically, you can't go as far on a tank now. Why do these companies assume we won't do the math.

I bet they think this may help the sumping issues I have always been a big fan of larger oil filters However why now as Alan said in his post. The MOCO is up to something here, look how many oil pumps they have redesigned already in a quest to fix the oil problems on the M 8 engines.

Jack' The Motor Company works in Mysterious ways....And you'll just get a headache trying to unstand their ways......But if you were to try' Think $$$$.....

Discussion on another forum talked of the filter allowing more flow when the filter starts getting clogged late in the service life. Interesting read.

My guess is that it is a combination of the three things mentioned so far.

Definitely will reduce possibility of sumping.

Definitely gives them a new profit center of another filter element.

Paper filters are fundamentally flawed, in that they clog up and reduce flow. This is never good, regardless, but an especially sensitive issue on engines that have a weakness for sumping.

Another, oh so slight, advantage is that with more flow there is less drag on the oil pump, resulting in a bit better power.

I've been using Performance Reusable Filters for, coming up on 2 decades. They flow 7 times more oil than a paper filter AND filter contaminates out better. So it is a non-issue for me.

Anyone seen this new filter at the dealer?

Nope. None yet at my dealer. I just checked yesterday.

I would like to cross reference it to see if a twin cam can use one

It may hit the crank sensor and or the stator pug

Remote filter may be in my future it's no big thing I only change oil once a year thank you Jack. Stay Safe, Stay Home, Stay Healthy... Fred

I just came from the dealer and they said that they won't be available until after the 15th.

I think if I had an M8 that "needed" more flow, I'd get the DK filter ... 7 times the flow ... I was really impressed with the quality of the build and ease to take it apart to clean.

[PosseRider]

I will be needing one about that time.

I am about 1,500 miles away from my next service. Probably won't need the new filter until middle or end of May. Works out good for me. I'll try it before deciding on relocation filter kit from Kevin.
