It's your car and your money. Do as you like.
We have just ordered a new car, and with a cost of nearly $40,000,
you can bet it will be pampered.
Frequent oil and filter changes are not expensive, and -whether
they are needed are not - help my peace of mind.

A filter works best after it's been in service a while and the larger
pores are clogged. I remember some people used to change their filter
every other oil change. The filters are much smaller now days but I
still wonder if changing the filter every oil change is necessary or the
right thing to do. My Toyota warms up quickly, very quickly so I
change the oil every 5K miles, my old pickup gets driven not much and
doesn't warm up very fast. I'll change it every 3K. The old oil I
pour around the house foundation, and on the wood fence. The termites
have eaten the hell out of the untreated parts of the fence. They have
not touched the treated wood.

There have been a lot of claims that the small particles which may increase
in motor oil with time do a lot of damage, but I have never seen factual
on this. And I have searched for it.
While filtering of smaller particles often does improve as the filter ages
the larger openings become blocked, I am not sure whether the loss of flow
is justified by the removal of smaller particles.
I have often wondered if there might be a case for installation of double
filter units (as some remote filter adaptors provide) might be a good thing.
What I THINK I KNOW, is that if you change the oil and filter regularly,
it is not unrealistic to get 150,000-200,000 miles on a engine with little
wear and damage. And this is what I am shooting for.
Nothing can preclude catastrophic failure in an engine due to bad design,
casting flaws, or weakened parts.

Quality does not prevent it from getting dirty and it is the dirty and
acid that build up in oil and that cannot be filtered out that
requires the change. Also most conventaion oil start to break down
with a viscosity shift by 3K miles or so and if you did a flow test on
you modern conventional oil after 5 K vs new you would likely be
surprized and rethink this whole thing. New engine are harder on oil
than ever these days.

You need to read what is truly severe service. Jiffy Lube et al would
like to convince you that starting the car up and moving it out of the
driveway is severe service. Ford (and other manufacturers) have tried
to be more exact in order to dispell this misinformation spewed out by
the oil change industry. For a 2007 Ford Fusion, Ford has the
following say about "Special Operating Conditions;"
"Items Needing Special Attention
"If you operate your Ford/Lincoln/Mercury primarily in one of the more
demanding "Special Operating Conditions" listed below, you will need
to have some items maintained more frequently. If you only
occasionally operate your vehicle under these conditions, it is not
necessary to perform the additional maintenance. For specific
recommendations, see your dealership service advisor or qualified
3000 mile oil changes are recommeneded for the following "Special
Operating Conditions" (refer to the above statement - occasional
operation in one of these condition does not make it necessary to
decrease the oil change interval):
* Towing a trailer or using a camper or car-top carrier
* Extensive idling and/or low-speed driving for long distances as in
heavy commercial use such as delivery, taxi, patrol car, or livery
* Operating in dusty conditions such as unpaved or dusty roads
* Off-road operation
* Use of E85 50% of the time or greater (flex fuel vehicles only)
Again, these conditions only apply if you operate your car "primarily"
in one of these conditions. Most people aren't towing something "most
of the time," most people aren't using their cars for Pizza delivery
most of the time, most people don't operate their cars on dusty roads
most of the time, or off road most of the time.
Clearly Ford is trying to walk a fine line. They are trying to
counteract the Jiffy Lube 3000 mile oil change propoganda for average
drivers without giving free rein to people who actually do need to
more frequently change their oil.
