Some "Premium Oil Filters" sacrifice some degree of "filtration" for "flow"...a dual filtration set-up is worth a look for some who want the best of both worlds...Fred can hook you up with a good one I am sure...

Racing Filters:

-Fram Racing flows the most and has the highest burst capacity as well. They filter only average...but then again you change every 10hrs or after every race..so who cares..right? Flow is critical!!

-K&N filters more but flows a bit less...it is a good overall offshore engine filter unless you RACE at WOT all day long!

-Wix Racing has a bit more filtration than a K&N but very close.

-Mercury Racing filters are quite similar to a Wix racing they tell me.

-Mobil-1 and Amsoil SD filter extremely well and flow pretty darn good. They are a first choice for most who do NOT race and do not have hopped up mills.

-A/C Duraguard are well constructed...filter and flow well...and cost $3.99. Go figure...but NOT for racing!

Hope that sufficiently confuses you!

It'll be interesting to see some test results with the new Amsoil filters.

That's great information, Hydro. What would you recommend that I use with 540s na using Mobil v-twin? I will be turning the mills at 5,800. Thanks.

Has anyone tested the ones from Billet Marine?

I gotta tell ya..the $3.99 A/C Duraguard does a real nice job...and Mobil says their new M-1 filters are improved...so I would go with either depending on what you want to spend.

if you order Amsoil products might as well go with their filter.

Run hard..then go with K&N..Baldwin or Wix Racing or the Mercury Racing...

WOT all day long with a hopped up rig...then only the Fram Racing...

I know a guy who ran these on his Sterling...worked very good!

As an AMSOIL Dealer I continuously review the specs the competing products and manufacturers. I have some info that may help when considering an oil filter for your pride and joy.

FRAM:
Single pass particle retention efficiency of the models is (per customer service):

HP1 98% at 40 - 50 microns max flow 10 gpm
XG8A 96% at 10 - 20 microns max flow 3-4 gpm
TG8A 98% at 10 - 20 microns max flow 3-4 gpm
PH8A 96% at 10 - 20 microns max flow 3-4 gpm

WIX: (per WIX website and filter rep at a filtration meeting)
51060: Standard Filter
Beta Ratio-2/20=13/23 50% @ 17 microns & 95% @ 41 microns
Max Flow 9-11 gpm
Burst Pressure PSI = 270

51060R: Racing Only Filter
Max Flow 28 gpm

AMSOIL EaO Filter: (per conversation with filtration engineer at corporate headquarters)
EaO filter line flows 9-11 gpm while maintaining high filtration efficiency (98.7% @ 15 microns). BTW: The AMSOIL SDF line of filters has been out of production since last fall.

Mobil 1: (per rep at Champ labs)
M1-303
98.7% @ 18 microns
50% @ 5 microns

Summary: Most people look for a balance of flow and filtration to some point. Some want more flow others more filtration. You will find that the standard WIX and the Fram Racing HP1 both filter and flow very similar. The WIX Racing flows the highest out of all the filters I could find. For filtration the Mobil 1 is very close to the AMSOIL EaO filters with the AMSOIL coming out on top. While it has the best filtration the AMSOIL EaO filters flow just as well as the Fram Racing HP1 filters.

I am not a fan of the reusable metal mesh filters at this time.

On a side note FWIW: I have provided both WIX Racing Filters and AMSOIL EaO filters to race teams that I sponsor and no team has had an oil or oil filter related failure that was brought to my attention.

Hope this helps or causes more great conversation.

Wix..Amsoil and Mobil-1 all filter about the same from the data on the past post...good to know.

Hydro - I have paid for an Amsoil membership because I am using the gear lube in my Bravo. What am I giving up if I use the Amsoil engine oil and filter? I was planning on using Mobil 1 and a Wix filter, but wondered if Amsoil's products are as good? I have new 540s and want to treat them right. Thanks.

.................the micron rating on all the posted filters, are the ratings absolute or nominal? ken
