The oil is supposed to last 25,000 miles just wondering if it really does? Pros and cons? Anyone have any opinions on this stuff??http://www.amsoil.com/shop/by-product/motor-oil/gasoline/sae-5w-20-signature-series-100-percent-synthetic-motor-oil/?code=ALMQT-EA

I don't know about the brand name, but I recently bought a new Nissan vehicle that uses 0w20 full synthetic oil.  I have never heard of such a thing as a zero viscosity number.
"I often say that when you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind."

I think these newer engines are working with much tighter tolerances so they do require a thinner grade of oil.

No its about fuel efficiency.  MFGs can squeeze a percent or two to MPG with these new oils.  Less friction during cold running.  Problem is these oils are expensive as hell if you can find it and really how much driving is done with a cold engine.  Does the extra MPG negate the extra maintenance cost...only time will tell.

Never used it, seen & heard of it.  Seems to be sold mostly via small time distributors, I have seen several trucks in the area that appear to be personal vehicles but plastered with Amsoil advertising.
The 25,000 mile thing is probably under ideal conditions, few if any people experience ideal conditions.
I can think of 2 instances where synthetic is worthwhile in my opinion.
1.  Car that gets little use, I would be more comfortable with a synthetic for a yearly or maybe longer oil change.
2.  When I was a kid (early 70s) we spent a winter night at Ft. Sheridan IL, the oil in our Mercury wagon got so cold it had the viscosity of grease and had to be taken indoors to thaw back to liquid.
Just my opinion, I tend to be cheap so just use conventional oil that meets the spec my engines call for.

If your vehicle is under warranty and you wish to keep it that way you should follow oem intervals.

I have been a user of Amsoil for everything oil related for over 30 years, could not imagine using anything else.  In their testing they state the ASTM test numbers, results, and competitors by name.  Nobody else does that.  I have used it in old cars, new cars, Corvette's lawn mowers, chain saws and boats.  Nothing beats is. {advertisement over}
