Amsoil By-Pass Oil Filter

[DBrena]

Anyone using the Amsoil By-Pass oil filter? Is it worth the $$$ and where is the best place to buy?

 

[rbattelle]

Amsoilman's got one on his. Nice setup. I'll get one eventually. I do think they're worth the money.

Another way of looking at it:

1. you are taking away pressurized oil that could be feeding the bearings

2. the engine will only last a million miles with stock oiling and one stock cellulose filter (not microglass or stratopore), with regular oil and filter changes. How much longer do you want it to last?

 

[Peter Campbell]

Uh-Oh. I'll brew another pot of coffe and get the popcorn going- this may be fun. ANOTHER AXXXXX THREAD!! Whoo Whoo!

That's funny! But 2 million with an Amsoil bypass would be nice. Heck, the engines would last a lifetime! We'd never have to buy another ... oops, I forgot we're driving Dodges.

I believe the filter increases oil system capacity 2 quarts, so you're not taking away any oil from anything.

To keep from having another AXXXXX thread, you might consider doing a search on past threads. You will probably get more info than you want - and these threads have been long at times. Many threads that start out for other info, end up as sythetic vs non-synthetic oil or aux filter vs standard filter debates -so you might do many different searches.



BTW, I am an Amsoil supporter.

I think you are missing my point. The sump is not pressurized. The bearings, piston cooling nozzles, etc. are fed by the oil pump and if some of that pressurized oil is diverted, there is that much less available for the engine. This is the reason why a very small orifice should be used to feed the bypass filter, as I believe Amsoil recommends. If the orifice is small, I doubt you are hurting anything. However, I wonder how much it helps. I had very good success with my 97 just changing regular Delo 400 every 3000 miles and using a new Fleetguard LF3349 each time. I think that engine produced as much soot and hp as you could ask for. I still like changing oil often, just as I prefer to flush my toilet frequently, rather than just adding Lysol to it.

What's a Toilet? I firmly believe we should all go back to the "Total Loss" system of oil lubrication, or better yet, Grease nipples, although, the non use of oil filters would throw millions out of work and perhaps cause a World Wide Economic Drepression, one has to think deeply, before making changes to what has been intelligently researched by certified engineers.

I use the Gulf Coast filter. Adds 6 quarts. Oil stays clean. About $400.

 

[draymorris]

Where is the amsoilman?

Chime in please.

Do they recommend an orifice?

I don't recall any mention of an orifice!

I don't know, I've got over 500,000 miles on my last two trucks with no lub problems. My present truck will roll over 107k tomorrow after just over a yr. That kind of mileage is why I use the bypass filter plus the Amsoil. If I changed oil every 3000 miles, I'd be changing every couple of weeks. Being on 24 hr call, I just don't have time for it.

Yes, Joe is right, there is a very small orifice in the mounting head of the Amsoil single bypass setup. I don't know what the pressure loss would be, but it wouldn't be very much.

I, too, think you're missing my point. With 2 additional quarts capacity, every ounce of oil diverted to the bypass filter is replaced instantly by at least 1 ounce of ouflow from the bypass filter, so components see no loss of oil whatsoever. This is not just Amsoil, I mean Gulf Coast, Oilguard, etc. Anyways, I'm probably splitting hairs here... . I mean no disrespect, Joe, just arguing points a bit.

 

[Joseph Donnelly]

Me too The systems I have seen sent the oil from the filtration ssystem back to the pan or inside a valve cover, so it is not adding to the pressurized supply, just going back into the sump. Indeed, it would be virtually impossible to return it to the pressurized oil galley and get flow through the filters. The pressurized galley is what needs the volume and pressure to feed bearings, etc.

I have nothing against more oil filtration, but I think all aspects should be examined.

 

[RHinds]

Amsoil's dual remote location system returns all oil taken from the engine back to the engine because it's only connection point is to where the oil filter mounts. They use a billet adapter for connection here. I feel it's a very nice setup and ideal for mounting anywhere you would like.

 

[ddutil]

Without secondary filter, my oiled stayed clean for 300 mi, with the filter it stayed clean for 6000 mi. The difference was obvious.

I think this add-on should be put in during the ''early days'' of the truck when there's more metal wear due to the break-in of the engine. After 100k mi, I dunno.



Even with a brand new filter the flow is very small (5+ minutes to process the crankcase content according to Amsoil, un-verified), the passages are needle-pin size, and the flow gets smaller as the filter slowly plugs with the sub-micron dirt (took me 2 minutes at idle to fill a 120cc bottle for the oil analysis).



Frankly, I don't see how this could translate into a dangerous low-lube condition, as the lube pressure was found by fellow TDR members to greatly vary (between 25 and 125 psi if I correctly recall).



My only advice: get Amsoilman's tricks-du-jour , this will ease the install. Dan

Have you mounted one on a 3G? They are tough to get wrenches on the adapter fittings. I am a supporter of Amsoil, but I wish I had installed a side stream filter unit with the single filter.



Questions related to the loss of pressure -



What is the oil path through the engine?

What is the minimum pressure for the oil to "do its job"?

 

[smartineau]

Alright I am getting lost here, yes that is easy for me to do. But I would like some clarification/opinions.



With the by-pass filter how much loss of pressure could there be? My idiot gauge (hopefully the actual sensor) will alarm if I get low oil pressure. Assuming that I have say 40 psi of oil pressure would a 2-5psi difference matter?



If it is winter and I am running 5w-40 won't my oil pressure also decrease?



I can see if the difference was in the 10-20 psi drop in pressure to the main stock oil filter but I just can't see a small change making a difference.



TIA, steve

Guys, member CPFF - John Strenkowski - sells mount kits and billet adapter kits for 3rd gen trucks. The adapter that comes with the Amsoil kit is NOT billet, and is prone to leaks etc. Johns kit comes with pictures of every step of the install, and the billet adapter is sweet. I have both the amsoil bmk-15 and john's kit sitting here in front of me. I'm just waiting for the ticker to hit 15k miles before I go synthetic!



The mount kit is completely bolt on, no drilling. The bmk plus johns kit came out around $300.

JOE-what you say would be true IF the oil bypass system took a significant amount of pressurized oil from the system but they do not. Fact-Amsoil and the bypass filter I use, puradyn, limit the oil flow with a small venturi in the pressure supply oil line to the filter system. These filters limit flow to about 6 gallons an hour. Now I believe the cummins oil pump at 50 psi is pumping 6 gallons of oil every 38 seconds so I believe you are displacing less than 2% of the oil flow over an hour of driving. The key behind these bypass filter is very low pressure slow filtering to remove particles down to 1 micron or less in size. I like the bypass system because I don't have to worry about changing my oil on long camping trips or any other long trip with my vehicles. Sure you could probably get the same longevity out of your Cummins if you changed your Dino oil every 3,000 miles as I will out of never changing my oil (either Dino or Synthetic). I been using these filter systems for over 10 years and have racked up over 580,000 miles on one 8. 3 Cummins and after a bottom end tear down we had NO wear and all bearings and wear parts were within factory new specs. My 99 has had one installed for over 100,000 miles and when we took out to put in cam we had no wear and not a spot of sludge. Have you ever seen bearings that were so polished you could see yourself in them? I did and they had 4 years and 100's of 1/4 mile passes on them. Yes I could change my oil evey 3,000 miles but why would I want to?
