Removed Amsoil duel bypass system.

[jjohnson1177]

After talking with several professonals ( I'm not saying who because I don't want to start a flame war here) who most of us would consider experts on our trucks I removed my Amsoil duel by pass system when I changed oil this afternoon. I went back to a single Fleetgaurd filter and Mystic 15-40. After carefull consideration I didn't feel that the extended oil changes and the extreme possiblity of fuel contamination in my oil was worth the risk. Also the cost of the filters and and oil and having to order them was prohibitive in my opinion. I think for a stock unaltered engine the system would be well worth having and I think that the quality of the product was super, it just wasn't right for my application. I average close to 600 miles a week right now and in Sept when school starts again I will be doing about 1000 miles a week. I think that this will also provide a good opportunity to crawl under the beast on a more regular basis to make sure things are as the should be.

I removed mine too. Leaked a bunch and once I figured out the thing would only accept the Amsoil filters and I was cornered into buying only Amsoil filters from them on..... off it came and into a box it went. I just change a little more often now.



Its too bad you cant have an opinion like the guy who told you to remove it and not worry about being slammed on the TDR for it.

Actually Don, on my last oil change I used the stock fleetguard filter in place of the bypass filter and a new amsoil filter as the full flow. If I can find another fleetguard filter to take the place of the amsoil full flow I might put the system back on and use the oil I'm running now. I do think the duel filter idea is a good one. I really didn't have any leaking problems just a film on the filter top every so often. I just don't like the idea of fuel in my oil so regardless I won't go back to extended drain intervals. Also the reason I didn't name who I talked to is because he is a very well known vender and believes in Amsoil oil, just not in the application that some of use are using the by pass system. I don't want to cause him any heartburn.

Why are you getting fuel in your oil?? I've run my by-pass system for 170K mi. now, and have never had fuel in my oil.

I think he meant soot. I too like the idea of having the by-pass system on my truck. Clean oil is good, but I could no longer deal with leaks and being stuck with the amsoil filters only.

I'm sorry to hear that. It is never a bad thing to increase the filtering capability of an engine *provided* the add filtering does not decrease oil pressure more than is acceptable by the engine manufacturer. Even if you switched back to dino oil and 5K changes, you can still only help the engine with bypass filtration.



If you've had other problems, then I could understand removing the bypass system.



Since sigs are not appearing, I'll also state that I am an Amsoil dealer (for personal use and I supply a fried or two), and please to note that this is the *only* sentence in which I've mentioned or implied that name.

Don,



can you explain why you are stuck with only being able to use Amsoil filters?? Are you talking about the bypass filter, full flow, or both? I'm just curious.

Somebody on TDR is running a Fleetguard instead of the Amsoil on the full flow side. I believe it is the Factory filter for our trucks. Apparently Amsoil make an adapter that screws onto the full flow side that changes the thread size to the same size as the factory mount. Been meaning to do this to my truck but figured I would wait untill my next oil change. Oo.

 

[jjohnson1177]

When I said I was getting fuel in my oil I meant soot, and as I stated earlier for a stock truck I think the system would be great or if there were other filter choices, which I'm sure there might be, I just don't know what they are. By all means if anyone has any information on this please post it.

Once again, the idea of the By-Pass system is to use the Amsoil By-Pass filter- that is the heart and soul of the whole deal.



It makes no sense to put two full-flow filters on a By-Pass system.



Extended drains are not for everyone.



Sounds like the system was working fine, it just was not what you wanted to do.

The by-pass system I have uses a full flow filter and a by-pass filter. I tried to use the Fleetguard filter as the full flow on the system. It does not fit. The only thing that appeared to fit was the Amsoil full flow filtter. The threads were different.

Of course the by-pass filter from Amsoil only fits the system as well. I did not really mind using the by-pass filter at all cuz I was only going to change it every 20K. But the full flows are supposed to be changed every 7K according to Amsoil.

The non-availability of the full flows at the local store was the gripe I had.

I kinda felt roped into buying something from Amsoil without a choice in filters.



Maybe there was a filter adapter or a Fletguard that would have fit, but I was not aware of one.



All this was happening at the same time I was having other troubles with Amsoil and I just decided to yank the whole mess and go back to what DC and Cummins designed in the first place.



Don~

 

[yogibear]

Well, DC and/or Cummins designed our lift pumps. How are they working?? There are some aftermarket pumps doing better, so I've heard.

Actually that would be me. I didn't like the idea of being forced to use Amsoil only filters. I happen to like the Stratapore immensely (as filters go) and wanted to stick to that. I only bought bits and pieces from Amsoil and made my own Stainless/Teflon lined lines with full radius ends. Also happened to use CPFF's adapter and battery mount. Nice items. Anyway, I was fooling around with filters and the dual mount block and found that the Stratapore screwed right onto the Bypass filter stud! Well, as simple as getting on the phone and ordering that piece to replace the fullflow stud and Wa-La! A bit of Loctite and done deal. The hoses and adapter what make it worth it though. The right angle fittings just don't cut it my book.

[jjohnson1177]

That is a good idea Todd, I also figured out the fleetguard filter would fit where the by pass filter went. I didn't think about ordering the stud from amsoil to replace the one for their full flow. I also think fleetguard filters are great and two should do a great job. I think I may also check with Cummins, the stud that is on the engine might work also. You can buy 3 Fleetguard filters from Genos for the price of one Amsoil filter. One other thing, I noticed my oil pressure went up about 10 pounds going back to the stock set up and I know that's a good deal .

 

[Sled Puller]

Do you guys understand what a By-Pass is?

If you want TWO full flow filters, call Summit and get a kit from them.

You are wasteing a lot of money buying a By-Pass system and

not using a By-pass filter! Your are killing the whole purpose!!



No full flow will filter down to a tenth of a micron, take out water or soot.







And who is saying it is ok to MAIL order from Genos, but it is inconvenient to MAIL order from Amsoil!!?!?!!?



LOL!

 

[gitchesum]

So does this mean someone had a dual by-pass oil filter system for sale?

 

[jjohnson1177]

From everything thing that I've heard no filter will filter soot or water, and as far as the mail order goes I can buy 3 fleetguard filters for the price of 1 full flow amsoil filter. I'm not even bring into the fact the cost on the by pass filter. What I'm fishing for here is a lower cost alternative for the full flow part. I still believe if you are getting soot into the oil the oil needs to be changed, I'm not arguing about the quality of the amsoil products, just if it's containinated it needs to go. I can't justify the higher cost of the synthetic oil when it should be dumped as often as the dino stuff "if" it has trash in it. 3000 mile oil changes have always been a good rule of thumb and will always be.

 

[drawson]

I am running the single AmsOil bypass and I run the full flow filter in the stock location. You would still have to run the AmsOil bypass filter with this set up but you could run any brand of full flow filter. The bypass filter has a very small hole that only allows a very small amount of oil. The bypass filter down to a 1/2 a micron where the best full flow is in the 7-10 micron areas.



IMO running a bypass filter in a great impovement over the stock filtering system even when running dino oils and draining them often. This is even needed more on bombed trucks!!!!!!

 

[Don M]

I agree with Dee on this one. You can always run a single by-pass and you only have to change the big by-pass filters once every 20k or so. They are kinda spendy though to purchase.

Since Im bombed to the teeth with mods, I change my oil all the time to get the abrasive soot out.

Im still a fan of the Fleetguards and they are on the approved list from Cummins and DC. The Amsoil full flows are not.

Don, thats a new "bombed to the teeth" that means that there's only the nose, eyes and forehead left, RIGHT. Hopefully thwey keep raising the line so that we don't run out of bombs
