I used to think the same way about multi-vis (as long as it was a good quality oil) but my experience with my Rodeo has changed it. It's 3.2l SOHC engine is very sensitive to lifter oiling. In the manual and a couple service bulletins Isuzu strongly insists on nothing greater than 10w30... straight 30 preferred.
It is very common for people to report similar problems (noisy lifters) after about 50-60k miles using 10w40 oils even following a good oil change regime. If lucky, a couple of flushes will remove or reduce the build up of varnishes on the lifter oiling holes and galleries and reduce the noise. I used 10w40 and also had noisiness... I flushed with Gunk (twice) and now use 10w30 in winter and straight 30 in summer with no more than occasional noisiness.
To be sure this engine's design is less than optimal but it serves to illustrate the problem with multi-vis oils. Even a properly designed engine will gunk and varnish more with multi-vis oils.

Amsoil 0-30 Series 2000 Racing oil. I was very skeptical of this oil as the old saying goes, "if it's sounds too good to be true it usually is". I tried 3k, then 6k, then 9k and so on. I now usually change the oil at 12500 when the first Amsoil filter change is. Since I don't run hard most of the time the oil comes out fine. I used to run the Amsoil 0-30 for 30k miles in my old civic. 200k miles later and the engine was still new! The person that bought it was a Honda tech. He wanted to know what oil I was using since the engine was in such good shape. He knew of Amsoil but didn't use it because of the multi level thing. It's funny how people think your in a cult because you taught your good experiences with things like oil. I have 2 car guru's at work that think I'm in a cult because I use Amsoil. They use Mobil 1. They think that industry standard tests don't mean anything. I'm only a user not a seller. I think some of their other products are mediocre at best and why the hell they sell house, garden and vitamin crap I don't know. It mars their reputation. Stick to the car crap!

I think of these as testimonials as much to how well made engines (especially Jap engines) as to how good motor oils are today... even cheap dino oils.

Ok, then let's forget the testimonials and go with independant laboratory testing using all of the accepted test standards such as the Noack Volatility tests. Amsoil consistantly comes out on top even with long drain intervals.

How can I benefit by using such an expensive oil, beyond the satisfaction of knowing it has the best performance in these tests?

I've been using Mobil One, haven't noticed a difference with the new formulation. Works great, I buy it @ Costco for between 21-22 bucks a six pack. Change oil and filter every 5,000 or 6 months. You guys think that's a decent interval? It's worked well so far. Also I don't see the issue with putting in synthetic at the start, so it takes longer to break in, big deal. It still protects better. I put Mobil One in for the 1st time when my 2K2 had 94 miles on it.

The benefit comes in when you factor in the 35,000 mile or 1 year drain intervals. The 0-30 weight is the only oil that I've ever noticed a gas mileage difference in gaining a minimum of 1mile more per gallon. The Amsoil 5-30 I noticed no difference over Mobil 1. If you do go the entire 35k miles changing the filter ever 12.5k like Amsoil recommends then you will same a ton of money. Better yet, try their triguard and get their bypass filter and go 100k without an oil changed!

My experiences and thousands (tens of thousands) of others have shown it so.

Since I'm so hard on the car, I like to know that I have some of the best in there. I also like the better fuel mileage, the cooler operating temperatures and the fact that I don't have to dump used motor oil back to the environment. If we can manufacture and use a synthetic oil without any petroleum products why not use that and help prolong our petroleum reserves, why not? We will always be able to manufacture synthetic lubricants, petroleum is a limited supply. Will it dry up in our life time? No, but what about our kids and then their kids? Like Virus mentioned, the NOACK volatility of Amsoil is almost half that of Mobil 1 and even better than that compared to conventional oils, which leads to reduced oil consumption and lower emissions. Considering all the above, I defintely think it's worth it, especially if you don't change it every 3K miles.

Also, since I'm down there changing filters... it's very little hassle to just drain the oil at the same time. I cannot accept that you can run any filter for 12,000 miles... call me old fashioned but standard filters are just too cheap to play such games with. A bypass arrangement would be great, but expensive.
And, finally, I would very much like to keep my warranty in effect. If anything should happen I can give them a record book and receipts that document oil and filter changes every 3-5K miles. I wonder how quick Nissan would deny a warranty claim at 50,000 miles if I can only document one oil change in it's life!

You're right I doubt Nissan would react to well, it would definitely be a fight. On the other hand, if the failure is oil related, Amsoil offers their own warranty. I find it interesting that you would be concerned about a warranty claim on a Japanese motor with 50K on it, considering that three posts ago you mentioned the reliabilty of them. Kind of contradictory.

As I see it, the odds are vastly in my favor gambling on adequate wear with dino, than trying to get Nissan warranty service if something vital breaks on a 20,000 mile oil change.

I agree that Nissan would be a fight if you outright told them you were changing the oil at these long drain intervals. So don't tell them. It's up to them to prove what the cause of the problem is. Amsoil has been in business for over 30 years and has always had extended drain intervals and has never shelled out any money and is good standing with the better business bureau. I don't think they would be this squeaky clean if folks were having problems with the long drain intervals. Like I mentioned before, I did 3k, 6k, 9k and so on until I felt confortable with the long drain intervals. On the other hand, I like you think it's just as easy to change the oil when the filter change occurs. Amsoil's oil filters are very good at trapping dirt, but I think Mobil's are a tad better. Anyone have any comparison's on the filters? I just bought a K&N air filter today. The gaskets didn't seem to hold the filter in very tight. Is this normal? It seemed to go in ok, but I had to try several times to hold the filter into place.

If I chose the extended drain interval approach I would choose the option of presenting the Amsoil literature and my Blackstone results to Nissan reps and probably loose. But that's prefereble to the legal ramifications of a felonious fraud rap. And cheaper than attorney fees.

Amsoil uses a polyalphaolefin base stock which is created by combining ethylene molecules into hydrocarbon chains of uniform size and shape. This is commonly referred to Group IV basestocks.
Redline is a polyolester base synthesized from a chemical reaction between an alcohol and an acid. This is a Group V basestock
Castrol Syntec is made from a hydroisomerized and hydrocracked PETROLEUM DISTALLATE. Basically, they create a synthetic from a non-synthetic. This is a Group III basestock, probably what you were referring to.
Now, for Mobil 1 it's a little more involved. They use three different main compounds, hence the tri-synthetic label. Similar to Amsoil, one component is a polyalphaolefin, the second is a synthetic ester and the third is an alkylated aromatic fluid. It's the third compound that is interesting. An aromatic is a component of petroleum oil, and in fact is one of the compounds in dino oil that promotes seal swelling (the other synthetics use additives for this same issue to remain more pure). Notice I said PETROLEUM oil. This is where the new formulation comes in. Mobil claims this is in there oil in order to make it fully compatible with conventional oils, yet Amsoil and Redline manage to do this in other ways, which actually cost more money, but in my opinion, produce a better oil.

Not at all contradictory... there is a vast difference between a failure, where something breaks, and engine wear. Engines wear extremely well today due to improvements in design, engineering, materials and lubrication but failures still happen, albeit at a lower rate than previously. Nissan could (and probably would) deny my warranty claim on a failure (a broken crank shaft, thrown rod or blown head gasket for instance) on the basis I didn't provide proper preventive maintenance with 20,000 miles on an oil change. Is it safe to assume Amsoil would cover all of these as an oil-related failure?
As I see it, the odds are vastly in my favor gambling on adequate wear with dino, than trying to get Nissan warranty service if something vital breaks on a 20,000 mile oil change.
