amsoil, and their products
#31
Amsoil uses nominal ratings. Absolute is what is important. How many .1 micron particals does a amsoil filter stop on the first pass, probably less than 10 percent.
I have tried to get the absolute ratings from many different amsoil dealers AND the company. They will NOT release the absolute numbers only nominal. That tells me they are scared to release the data for a reason.

Now, THAT is very interesting! I appreciate your reply. I suppose the 10 % rate would be compensated by the fact that it does its filtering continuously. At any rate, my oil analysis tests always come back very good!

Thanks for the reply. I wonder how nominal is really defined though because there still comes a point where a 10micron filter MIGHT be able to get a .5 micron particle, the probability is horrible but it may just happen given enough passes. Another misleading advertisement just like how many amps a vacuum uses or how many watts a light bulb uses. It is like they encourage ineffeciency by not using actual power or lumens....

Does anyone remember the old (Frantz?) toilet paper roll filters? They had their own canister and were a horrible mess to change, but 40 years ago they enabled folks to get high mileage out of their engines before we had the oils that we have today. I figure that using a modern version of that, the Amsoil bypass, plus a fully synthetic diesel engine oil ought to give me pretty good odds at high engine life.

Frantz still makes those filters, somebody on TDR made a nice thread on his.

He says just wait overnight to change the filter then there is no mess, just makes sense since all the oil would drain out. The only difference between this and the amsoil bypass is that the amsoil is spin on cartridge which costs ~$12ea versus the Frantz which is self packed/ drop-in filter which costs $.80ea but probably requires a shorter interval.

I would like to thank all the highly technical opinionated who berate individual products based on personal dislikes. I have stated it before the MLM system Amsoil uses to market their products is bogus and not appreciated by many. This does not mean the highly technical advancements engineered at their cost is not some of the best available just like Royal Purple or Redline. It has also been stated that the "dealers-Amsoil" are less than honest or knowledgable while selling these products and others unlike every large chain or independently owned auto parts place in North America. If the best you can do is offer untechnical opinions based on heresay, table top discussion, wifes tales and that's what Dad did- why should any of us even consider this to be of any more value than bad sales people. Back to the subject at hand A@#$% is so far for me the easiest true PAO engineered lubricant available for most applications in my CTD. Redline is in my NV5600 for the same reason, based on the information people like Eaton Fuller who foolishly increase their warranty from 100,000 miles to 500,000 miles when using the proper synthetic engineered lubricants in their products versus regular old reliable petroleum oils. Perhaps using a local contractors documented use of PAO's on 86 pieces of equipment with increased life and reliability had something to do with my decision. Has there been mechaical failures "YES" all due to substandard mechanical components and operator abuse, of course this never happens with the Dad's recipe for equipment maintenance does it? A@#$% offers me 25000km oil changes because my time is important, it offers me better cold weather starts and hot weather protection, it DOES Not allow me to be abusive to my truck which gets me home every time. I would like to say thanks in advance for all the "Coffee Cup" commandoes who will slander my "opinion" based on technology to compliment my high tech fly by wire CTD. PS I work at one of those overbearing crude oil high profit tar sand refineries- we know what their objectives are!!!!PK

I hate being ignorant; worse yet is everyone else knowing I'm ignorant! Oh well! What is "PAO engineered"? I was hoping that at 25K I wasn't going to far on my Amsoil oil change intervals...glad I'm not the only one!

PAO = Polyalphaolefins = Synthetic base stock, ie the synthetic oil without the additives.
I dislike the way Amsoil has things setup through dealers and how their prices vary so much but I can overlook that for the quality of the oil. I think some of their data is a little crooked towards themselves and I surely don't expect it to go 25k miles between changes but I'd expect it to out live a normal dino oil and flow much better at cold temperatures. Anyone going much over the manufacturer interval should be doing testing, if you plan on going much past it you should also have a better filter system. All of the lubrication companies seem to be quite shy with allowing us to have information, I always love it when they don't keep the same testing standards even within their own company so you can't even compare their own oils.

Thanks for the definition! What you say is basically what I've done: I use their oil and their bypass filter, and test the oil twice yearly: just prior to dumping it (in the Fall) and halfway through. That way everything is fresh for our winter-time trips south to warmer weather, when I'm pulling the fifth-wheel. The tests always come back, "OK for continued use", but I change it anyway. And certainly cost is a factor; even doing it myself in a friend's garage, it's pushing $250CDN to do it all.
