I posted part of this article some time ago but I figure it won't hurt to do
it again:

Synthetics are not new. A researcher named F. W. Sullivan of Standard of
Indiana had an active research program underway in the 1930's. During the
Battle of Stalingrad in 1942, lubricants jelled in the extreme cold,
stopping
the advance of the German tanks. The Germans then developed synthetic
lubricants for cold-weather use. After the war, developers of the then, new
jet engines found that mineral oil lubricants wouldn't stand up to the jets'
searing heat. Esters solved the problem, and today are used in all jet
aircraft. Synthetics began to get attention as crankcase lubricants in the
1960's when the Army was trying to find better crankcase oils for Arctic
use.

Car owners were once directed to change oil every 500 miles. Slowly, as oils
got better the change interval grew to 1000, 2000, 4000, finally 6000 or
7500.
All on mineral oils. Mineral oils could undoubtedly be used under some
conditions far longer than they are now. Auto companies are conservative in
their oil change recommendations so that even those hardest on their cars
will have trouble-free service. Auto engineers work closely with oil company
engineers in developing drain recommendations. Since Mobil is one of the
major oil companies and doesn't want to upset its relationship with the car
makers, it is not claiming extended drain capabilities for Mobil 1 in its
ads.
Yet Mobil researchers clearly believe it can go much longer than the drain
interval specified by Detroit. How much longer? Mobil shows data on taxi
fleets that ran 50,000 miles with oil drain every 12,000. The torn down
engines were super clean and showed normal wear or less.

I change the filter and add a quart every 6K miles using
Mobil-1 Synthetic.
I personally don't believe that any filter is good for 15K
miles.

Why?

Are you relying on some structured documented testing, or are have you just
decided on a arbitrary number?

What criteria do you use to determine at what mileage an oil filter stops
filtering?
What tests/criteria do you use to determine at what mileage your oil stops
doing its job?
Why is it good for 6000 rather than 3000, yet not 15000???

I use Mobil One every 6-7000 miles. Most auto manufacturers recommend 5000
on an oil change unless under extreme driving conditions and then 3000. If
you look at their definition of extreme. The vast majority of people
driving don't need to change until 5000. Oil change companies go "safe' to
get you in their shops almost twice as often. As far as the 6-7000 I do,
I've got a 120k mile LT1 that I want to last a lot longer and figure the oil
change is my least expensive insurance. As far as the 12,000 mile oils. I
spoke to an Amsoil rep at the NCRS Winter Regional a couple of years ago and
they were promoting their 12000 mile oil. At that time, their
recommendation was to change the filter every 6000 miles and then top off to
replace any lost in the filter change.

I am relying on 41 years expierence changing oil.

years back, had an STP filter (used in a pontiac lemans)
decenagrate and stop up completely up after 4K miles.
but,
hold a new oil filter in one hand.
hold a used oil filter in the other hand.
which is heavier ?
why do you think one is heavier ?
the more miles on the filter, the heavier it gets.

> What tests/criteria do you use to determine at what

clear oil or dark oil ?
why is there a difference ?
which would you prefer.

> Why is it good for 6000 rather than 3000, yet not 15000???

reguarding synthetic
3K would be a waste of good $$$'s
6K is not too dark.
15K is damn near black.
