I'll give it a go. I installed a dual-remote bypass system on my '98 12V. See http://home.adelphia.net/~npmrphy/amsoil/amsoil.html for pictures. I currently have about 30K miles on the oil (Amsoil Heavy Duty 15W40). I've sent in three samples, changed the full-flow filter three times and changed the bypass filter twice. Oil Analyzers have said each time the oil is good for continued use.



The full-flow filter takes out particles down to around 25 microns. The bypass filter takes out particles down to around 3 microns at around 95% efficiency. Removing these smaller particles does help to reduce metal wear in the engine. The oil does tend to stay cleaner (not so black) much longer.



There are two bypass systems you can install. A single remote bypass that runs a small amount of oil through the bypass filter (your oil pressure does not drop more than one or two PSI, I believe). All the oil runs through the bypass filter every five or ten minutes I think. The single remote is usually plumbed into either the valve cover or into the oil filler cap. With this, you continue to use the stock full-flow filter. With the bypass return line plumber through the filler cap, taking an oil sample is trivial (run the engine, take the cap off and let oil fill th sample bottle).



The other is the dual-remote filter. This unit replaces the standard filter with a fitting that pipes the oil to the dual-remote unit, which contains both a full-flow and a bypass filter. While this system *may* reduce the overall pressure a bit, all the filtered oil runs through the engine. This unit also comes plumbed for a valve that enables easy sampling. OTR trucks that use bypass systems usually do not change the oil until the engine is rebuilt.



I believe Amsoil recommends changing the full-flow filter every 7K miles or so, and the bypass filter with every other full-flow change. You would probably want to send in an oil sample before each filter change, at least until you get a feel for how the oil is 'wearing'.



The main advantages to using a bypass system *with* full synthetic oil (e. g. Amsoil):

• less waste oil
  
• less time spent changing oil
  
• slightly better fuel economy, from using slicker oil
  
• less wear on the engine
  
• over time, less maintenance expense
  

Disadvantages:

• you must remember to sample the oil for analysis
  
• you must remember to not allow anyone to change the oil
  
• you're less likely to find Amsoil on the road, should you need some (I haven't yet needed any whilst traveling, though)
  
• mounting the unit and running the plumbing can be a pain; there isn't much room under the hood! TDR member CPFF (sp?) sells a nice adapter, hoses and a mounting bracket for the Amsoil unit.
  
• sometimes you can have leaks in the plumbing; these are usually cured by tightening the joints even more.
  

Generally, I've found the advantages far outweigh the disavantages.



If you wish to buy a system, let me know. I'll sell it at cost. Per my sig below, I *am* an Amsoil dealer.



Other members may be more organized and have the related TDR posts handy.



If I've made any errors, please let me know. I will correct this post as needed.



Now, I's'll don my fireproof environmental suit, as the flames will surely fly now: oil can be something of a religious topic here!

I have te Amsoil Dual bypass and the complete CPFF install kit, battery mount, braided stainless lines and the billet block adaptor. Never had any leaks at all, simple to install, no drilling or cutting anything, just simple hand tools and about an hour or less to do it. The lines are pre assembled and are sized perfectly to go from the block the dual bypass. CPFF also sells the dual bypass kit.

Excellent discreption of the Amsoil system. I have one. I use the dual system and have it mounted directly below the radiator. The unit sets dead square in the middle of the frame and behind a WARN front receiver which has a 1/4 inch armor plate bolted to the back of it and up to the cross member the the filters are mounted to. That provides me with plenty of crash and bash should I need it. I have the quick change oil fitting from Geno's in the pan. Total oil change out time including the filters is 6 minutes tops. I can change the filters in about 30 seconds. I will see about borrowing a friends digital camera to post some pics. This system works very well for me. If you do heavy off roading then it would be on the low side. I too have the sample port. The line for this out fit just drop straight down from the original oil filter mount point and do not touch a thing. 15W/40 is the weight of Amsoil I use and it works very well.

Hello Everyone...

I've stayed away from Amsoil in my truck. I had 2 diesel mechanics tell me not to run it. They said it was good for gas motors - but not diesels???



I'm new here and done a search and hit this thread.



Any opinions welcomed.

Neal, I would be interested in seeing the results of your oil analysis - how many miles on the oil? I'm particularly interested in seeing the wear metals and silicon numbers. The bit about sending the output from the bypass into the engine along with the full-flow oil would seem to be an excellent idea, why NOT send the CLEANEST oil directly to the engine!

I've got about 28K miles on the oil. I've put in perhaps 6 qts. of oil. (The fittings leaked a bit, and one or two of the valve covers leaked. That's all fixed now, so I shouldn't be using any oil anymore. I *could* check my log book to see exactly how much I've added, but I don't feel like it. )



The analysis results:

Miles on oil 19500 28524

Physical Properties:

  Glycol:  neg. neg. 

  %water:  <. 05  <. 05

  %fuel:   <1. 0  <1. 0

  viscosity@100 degrees:  13. 2  13. 4



Oil Degradation:

  soot: <1. 0  <1. 0

  %oxd: 8. 9   11. 1

  %nox: 8. 6   10. 0

  tbn:  12. 3  11. 9



Spectrography (PPM):

  Fe:   52 53

  Cr:   2  2

  Pb:   6  4

  Cu:   2  3

  Sn:   1  1

  Al:   8  9

  Mn:   1  1

  Si:   6  15

  B: 32 20

  Na:   1  3

  Mg:   130   99

  Ca:   4342  4378

  P: 1232  1254

  Zn:   1330  1399

The first sample, at 19500 miles (on the oil, 84798 on the truck), had maybe 4 qts of oil added over time. The second sample had 2 qts added a couple weeks and a couple thousand miles before the sample was taken.



Es bien?

BShelton,

Don't sweat it, Amsoil has heard the old guard say it won't work in this or that for close to 30 years now. They just keep proving them wrong!



There are just too many millions of miles on Amsoil in Big Diesels over the last 25+years to say it does not work.

Hmmmmmmmmm! Let see, I've been running Amsoil for about 20 years in all of my vechicles and we got a couple of yahoo's (oh yea they call themselvs mechanics) that say it is a bad thing for diesels. I suppose that they have the ultimate answer, but that it requires that you buy from them or some such thing. Or could it be that they would rather you use something different so that they will be able to get their little mits on your engine and be able to charge big bucks. Come to think of it, I've owned 9 vechicles over 30 years and 3 of them have been diesels. Each one has had well in excess of 180,000 on it and I have never had a mechanical breakdown of any type with the engine. Guess I'll just keep running this crappy old Amsoil. It seems to work ok for me. Sorry about being a bit on the touchy side. I haven't had my anti-grump shot today.

Thanks for the replys Guys.....

I run a small lawn care out fit, and I'm switching over to Amsoil in all my mowers now. The 100 to 1 premix is great.

I believe next oil change ( 50,000 mile mark), I will introduce the cummins to Amsoil, and a by pass filter.

AMSOIL

I used to commute from Suffolk County, Long Island to Brooklyn N. Y. which is a 100 mile trip to work every day. Back in 1983 I bought a new Mazda B 2000 gas pick up truck 2 wheel drive and 5 spd. Had the truck on Amsoil turbo 10W30 oil and their cartridge by pass filter system after the first 10,000 miles... . put over 230,000 miles on that truck and never touched that engine except to change oil once a year, adjust the valves, flush coolant, replace spark plugs, wires and distributor cap and rotor. Engine ran great when I sold it and never, ever burned any oil. When you pulled the valve covers there was absolutely no sludge what so ever to speak of, simply spotless inside. I have been using Amsoil since 1983 and have never lost an engine. Everything I own is running on Amsoil, the oil works great and that is a proven fact!!!!



Good luck with it, most people I know that try it never go back to petroleum oil again. Hope it works for you.
