Found RP 30W on Amazon in a 20 qt jug for $127 so $6.35 a qt with free ship

Here is the list of AMSOIL/Donaldson filters in order for the Mercury blocks.
EAO-59 shortest
EAO-25
EAO-24
EAO-76 (2qt filter)

Understanding the difference between the stock and racing oil filter versions, I would like to explore switching to a "finer" filtration oil filter. I do have a question.

Currently have a remote filter unit that requires a 3/4" NPT filter like the HP6A Fram. The link below shows the cross reference filter list. Does Amsoil have a replacement for the HP6A?

Keep in mind that most use a 1/2" NPT, correct?

The mobil 1 number M1-302 crosses to a EAO-24.

Looked on the Amsoil site and could not find a tech sheet on the EAO24 oil filter. Help. Does this filter truly have a 3/4 NPT fitting?

http://www.aa1car.com/library/API_ratings.pdf looks like a SN oil would give you the protection of a engine rated for SL OIL???

I think this whole oil thing is beaten to death. And that filter has worked fine for years...

X2...I'm thinking now there's 3 things that shouldn't be discussed; Politics...Religion...and Oil Filters!:lolhit::lolhit::lolhit::lolhit::lolhit:

13/16-16. I use the Wix crossover which gives you the full details of the filter.

Amsoil EA filters are made by Donaldson, you can get the specs there.

I would compare the filter media of the K&N to the Amsoil EAO series. I did a lot of research when I bought my boat a couple of years ago. I looked at K&N, Mobil 1 Synthetic, WIX, Fram, Donaldson (Amsoil) etc. The filter media in the Donaldson filters is the best I could find. The fibers are very fine and uniform so you have more open area per square inch verses a cellulose fiber as in the K&N, WIX etc. The high uniformity also allows for better filtration of small particles. I personally use the EAO76 filter on my 522, almost 2qt capacity, no flow restriction whatsoever. Can't tell if the oil comes out cleaner then it went in.

My question is: At WOT for a typical 500+ C.I. motor, what flow rate is required (minimum) for the oil filter?

It appears as the micron filtering number decreases, so does the flow rate (GPM). Finding an oil filter with a micron number of 20 and a flow rate (GPM) of 25+ would be great. Any thoughts-----suggestions?

Amsoil EAO76 is about 1.4qts and has a 20 micron rating. With that amount of surface area of high flowing synthetic media, I doubt it will have any difficulty flowing what you require. I run my 522 to 6k and I have no problems.
