If you change your oil every 3k miles, your getting the same protection as
using a synthetic..

(one note about extended oil drains: although some synthetics supported
drains, it is still recommended that you change the filter every 3k miles or
use an aftermarket filter that can support longer intervals).

I've run Mobil 1 5W30 since first oil change in my '96 5.8L Club Wagon, 104,000
miles. No leaks, no smoke, no oil use. Seeps a little where the dipstick tube
enters the engine. :-) but doesn't drip or anything, just a little wetness.
Runs like it was new.
Don't use AMSOIL products or Fram filters.

If you do any heavy pulling with your vehicle, another advantage of
synthetic is its ability to lose heat better than any regular oil. In other
words the oil temperature will run cooler with a synthetic than with
conventional oils.
I believe Todd is technically correct but from a practical
POV Roger has it right. The anecdotal evendence from race
car drivers and other high performance scenarios not
withstanding I provide the following from
http://www.repairfaq.org/filipg/AUTO/F_Slick_502.html#SLICK_001
even though it is written for motorcycle engines where it
would apply even more because they are for the most part
more high performance than any auto/truck motor on the
market.
""Synthetics and synthetic blends offer a wider range of
protection than standard petroleum products. However, it
should be noted that this extended range of protection
reaches into an area of temperatures and pressures virtually
impossible to attain inside most motorcycle engines and
transmissions. In other words, if you use them, you are
buying a sort of "overkill protection." It's certainly not
going to hurt anything - it's just unnecessary. That is,
unless it makes you feel better knowing the
extra protection is on board, in which case the added
expense may be well justified.
As a basic rule of thumb, using the standard engine oil
recommended by your bike's manufacturer and changing it
about every 3000 miles will afford you all the protection
you'll ever need. But if you feel better knowing you have
more protection than you need or, if you like the extended
service-life feature, there's certainly nothing wrong with
using a premium grade synthetic blend lubricant.""

Actually, it IS. It is possible to create a pressure drop across the
filter media if the level of filtration is to great.
This will either cause low oil volume to all parts downstream from the
filter or cause the by-pass valve (if equiped) in the filter to open
creating a situation where your engine is being lubricated by un-filtered
oil.
Think about why a filter needs to be changed more often if the engine is
operated in dusty conditions.

Oh, so oil travels from the filter to the pan does it?
Or is it oil travels from the filter to the pan when the by-pass valve opens?
Then again, what good is oil that has by-passed the filter?

As far as filters in general, some do have a by-pass valve, some don't.
Pretty easy to determine by reading the technical sections of any major
brand filter catalog.

Sounds like you've jumped from describing the function of a standard
replacement filters by-pass valve to describing a "by-pass" style filter,
not that it matters, please describe for us the advantage of having oil
routed back to the oilpan from the by-pass valve on this filter that has a
plugged media. If the oil is routed from the by-pass valve directly back
to the oilpan because of a plugged filter, the engine is being starved for
oil supply. If the by-pass valve is opening to allow un-filtered oil to
supply the engine, the damage is merely postponed, not eliminated.

Again, you are incorrect. This has been proven by independant oil analysis
done on motor oils..
A decent quality dino oil is good for 3 to 5k miles. (Havoline, Valvoline
etc)

Again, you are going against Amsoils own recommendations. Here is the quote
from the Amsoil site about their filters:
-------------
"AMSOIL INC. recommends changing the AMSOIL SDF according to the following
guidelines.
In gasoline-fueled engines using any AMSOIL motor oil except AMSOIL XL-7500
Synthetic Motor Oil, change the filter at 12,500-mile or six-month
intervals, whichever comes first. In gasoline-fueled engines using AMSOIL
XL-7500 Synthetic Motor Oil, change the filter at 7,500-mile or six-month
intervals, whichever comes first.
In diesel-fueled large truck engines, change the filter(s) at the engine
manufacturer's recommended oil change interval. In diesel-fueled light
trucks, including pickups and vans, change the filter at 7,000-mile or
six-month intervals, whichever comes first."
----------
Going 25k miles on their filters is not advisable..
Going 25k miles on Amsoil's oil in a Diesel is also not recommended. Here is
the quote from Amsoil's site
--------
"SERVICE LIFE
Diesel engines, fleet vehicle engines and industrial engines: drain oil at
intervals up to two times longer than recommended by the engine manufacturer
or at six month intervals. Extended drain intervals may be used if they are
supported by the findings of used oil analysis.
Change AMSOIL Full Flow Oil Filters at 12,500-mile or six-month intervals,
whichever comes first, in gasoline engines. In diesel engines change AMSOIL
Full-Flow Oil Filter at 7,000 miles or six months, whichever comes first.
Change other manufacturers' oil filters at the engine manufacturer's
recommended filter change intervals."
----------
There is also a quote from Amsoil's site disputing your previous claim that
Amsoil doesn't use an additives, so there is nothing to wear out..
---------
(for the diesel oils)
"Extended Drain Intervals
AMSOIL Synthetic Heavy-Duty Diesel and Marine Motor Oil is formulated for
extended drain intervals. Its unique synthetic formulation, improved
detergent/dispersant capabilities, and long drain additive package ensure
maximum engine protection, cleanliness and performance over extended drain
periods. Its advanced 12 TBN formulation keeps engines in superb condition
even when the oil is used for extended drain intervals."
-----------
It's a free country and you can do/say what you want, however you are making
claims about an oil brand that even the manufacture of the oil does not
agree with..
btw, I currently use Amsoil in my truck as well.. But I follow their
recommendations..

Debbie, it has been a while since I looked, but about 2% of the crude
oil in the word goes towards lubricant manufacture.
Most synthetic oils are made from crude oil using a REFINING process,
leaving behind the crap they do not want. This makes a good lube,
better then the original mineral oil, but it is not a synthisis.
The API decided to change the industry definition of synthetic from
"Bonded molicules", to "more highly refined", at the time Shell, Mobil
and Castrol were before the courts for their advertising claims.
It is possible most SYNTHETIC OILS are just very highly refined
mineral oil like Mobil 1 or Shell or Castrol ( who use Mobil or Shell
products as their base oil).
Who knows??? They need to get their base from somewhere.
Regards
STU BOND
PS BTW I use Red Line Oil because of the number of world champions and
record holders that use it and because I have seen inside engines that
have been on it. It is a Poly Ol Ester and is made by combining small
molicules to make larger molicules. Hmmm a real synthetic.
Why the thick 15w40 oil?

Yes. For all practical purposes, most of the time I am running no filter
