This is all well and good if service intervals were just about oil and
filter changes. Would you really want to drive a car who's brakes and
other associated stuff had not being checked for 100 k miles. Remember
a lot of people don't have any sort of idea about this sort of stuff
and rely completely on the Dealer service to tell them when work needs
doing.

In the UK most people rely on getting the annual MOT certificate to
allow them to use the car on the road. In reality so few people with
cars that are not brand new ever see a dealer or even their local back
street garage unless something breaks - or unless they are forced to by
the car failing the MOT test..
For overseas readers MOT= Ministry of Transport. On a car's third
anniversary and every year after that it has to be tested. The tests
included rolling road brake tests, emissions, condition of wheel
bearings, shocks, steering, gaiters, CV joints - correct headlight
light alignment and general road safety issues. While this in no way
substitutes for regular services I guess it was introduced because a
large number of the population were not servicing their cars for 100k
miles :(

You raise an interesting point - except that I said that the 100,000
includes filter changes/top ups which means the vehicle is brought in for
some sort of periodic servicing. I think manufacturer's could think up a
better or easier way to have owners bring vehicles in then rather than
snow-jobbing them with the idea that they NEED oil changes every 4000
miles.
I think it was a Toyota mini-van that once touted extremely long intervals
for the oil - and to ensure that they made getting to the oil filter and
spark plugs so incredibly difficult that you had to PULL THE ENGINE to do
this simple maintenance. I don't know if they still have this beast on the
road anymore. (or perhaps Toyota was doing it's bit to kill of the 10-min
lube shops!)

Indeed the vehicle could still be brought in at a more regular
interval but if you look at the cost of a service by far the greatest
part of the cost is the hourly rate of the mechanics time to do the
job (unless of course there are major parts needing replacement) The
cost of the oil is not really that big a deal.

This argument has been on here before and I firmly fall into the 4000
miles is not long enough camp but you will also find people who will
defend it. I think the middle ground of it depends on the type of
driving dictates things like oil change frequency.

BMW and Mercedes have service computers in most of their cars. These
give service alerts to the driver based on various inputs inc records
of cold and hot starts, time elapsed since last service, oil pressure
etc etc. These are fairly sophisticated systems but obviously add to
the cost of the vehicle and I don't see Ford or similar adding it to
their lower cost machines.

It will depend on the user's driving pattern too. A lot of cold
starts and short journeys (where the fuel mixture is rich and the
temperatures low) will degrade the oil more rapidly. Reps running
200 miles a day on motorways won't degrade the oil so much.

I'd have to reject the idea this this guy knows every vehicle
application out there and can say in one blanket statement that for all
cases, all engines, all environments, a 100,000 mile oil service life,
even if it is synth oil, is appropriate.

No, they say this not to conspire with anyone, but more to cover their
a.ses. I think of it this way: if the oil manufacturers didn't want
people to know (shhh!!) that oils really last 100k miles, then why did
they go through the trouble to research and design an oil that COULD
allegedly last 100k miles? We would have been just as happy - and they
would have made more money- by not doing the research and manufacturing
the same old oil they've been making since the early 1900s, which really
would break down at 3,000 miles.
It is true that in *some* and perhaps many cases, oil will last longer
than 3,000 miles before it's time to change it (certainly not 100,000
miles though... maybe 5,000 or 7,500, but not 100,000). But the 3,000
miles schedule is still being pushed because in the worst case
scenarios, under the most boneheaded and wasteful and abusive of driving
conditions, the oil could be pretty foul after 3,000 miles, and require
a change. Since most drivers out there don't want to analyze their
drivings habits and make judgments, they're simply told to change it at
3k, no matter how you drive.
The only way to truly know how long you should wait between oil changes
is to have your oil regularly analyzed for contaminants and wear. Once
those contaminants reach a certain threshold and the oil has begun to
break down to the point where it no longer offers enough protection,
it's time to change it. However, there are a lot of cases where the
cost of sending your oil to a lab for repeated analysis is more
expensive than just changing the oil out at 3k and being done with it.

Hi
in Germany we have one company that is producing a special oil filter
that needs to be mounted in addition to the original oil filter.
With this filter you don´t need to change your oil.
You only need to change the filter cartridge every 30 000 Km and fill up
about 0,7 liters of additive when doing so.
There are many taxi drivers that use this filter for over 150 000 Km and
in Hamburg there are about five busses that have this filters fo about
500 000 Km with no problems.
The TV-magazin telemotor bought one VW Golf GTI in 1990 and provided it
with this special filter. After two years and 125 000 Km they gave it to
an special institute called DEKRA to make a studie about wearing of the
engine and they could not find any bad aspekt of faster wearing on any
part of the engine. It was just as fine as it should be after that
ammount of Km.
But the oil industrie wants to sell oil and the manufacturers of cars
want you to come by to the service station every year, so they are not
interested in such filter technics.
And so there is only one little manufacturer for that filters that is
struggling for a living.
