In Europe they regularly go to 15,000 to 25,000 mile oil change
intervals. They also have a different spec for their oil. There is a
new spec hitting the streets that will make most US oils, at least
those adhering to the latest and greatest specs, the same or nearly so
as the European specs and easily capable of going way beyond the
ridiculous 3000 mile to 7500 mile interval now called for. If you use
Mobile One even now you can easily go 12,000/1 year unless you are
operating under very severe conditions. I'm sure others will
disagree.

Is the age of the car a factor? If it was built for the oil of 15 years ago
then it should last longer with today's oil right?

It is amazing the volume of bollocks written by American idiots on the
subject of oil changes.
Using just ordinary dino oil meeting APISL it is now commonplace to have a
minimum 7500 mile service period. Better oils used in better engines allow
15000 mile severe and up to 30,000 miles in ideal conditions in a variety of
European engines.
Ford engines in Europe have 12000 mile/one year service schedule while GM
Europe have either fixed 20,000 or variable 20,000 to 30,000 mile intervals.
Not Kilometres, MILES.

And here in the states, it is common for heavy diesel trucks
to have 100K mile change intervals. 20K is now considered
short. I know of one large fleet that is doing 200K service
intervals with 1M overhaul interval. Another fleet only
changes the oil or filter based on analysis at 20K
intervals. They do, of course, have a greater crankcase
and filter capacity as well as bypass filtration which
helps. They also run for extended periods at normal
operating temps which allows the oil to do it's job. One of
the biggest problems with lube oil is not operating long
enough with the oil at normal operating temps - i.s. cold
engine start - short trips. The problem with extended idle
even at normal operating temp in spark ignition engines is
the inefficiency of the combustion process at closed
throttle producing more contamination. When I worked with
the RR loco engines, the oil was never changed unless it was
catastrophically contaminated or at the time of overhaul.
Even at the time of overhaul, we would run an analysis and
likely, run the cetrifugal purifiers on the sump and put the
same oil back in. The same was true in shipboard
applications. I consider a vehicle that has the oil changed
ever 3 mo/3K miles to be pampered. My personal vehicles
routinely turn over 200K miles on 5K changes using good
filters and name brand (most any other than PA crude grades)
dino oil.

I change the oil on mine every 3k because the engine design
had poor oiling to the bottom end due to design shortcuts.

Exactly as in Europe. Generally we use the same engines and same oils on
both Continents.

Consider the 2.5 V6 Ford engine. In the UK this has 12000 mile service
intervals. No doubt the interval is much shorter in the USA?
However, I do know that both Mercedes and BMW engines have similar intervals
on both sides of the Pond. In my experience both marques average 12000 to
16000 miles between oil changes.
VW however seem to have given up pushing their extended intervals in the
USA, not due to any technical issues, but due purely to consumer incredulity
born of ignorance. It is just less hard work and more profitable for them to
get mugs to visit them every three to five thousand miles because they wish
fervently to do so. It takes all sorts.

No, one of the banes of owning poorly-engineered machines. There are too
many current and recent engines with designed-in lubrication problems
(Chrysler 2.7, Toyota 3.0, etc.), and plenty of engines designed 25 (35,
45, etc.) years ago without *any* endemic lubrication problems.

'Bollocks'???
I think idiots from all countries write garbage about oil changes.

The problem, as I see it and as we have mentioned many times before, is that
there are a lot of opinions, manufacturers specs, and oil formulators BS,
but little trustworthy data.

One of my old bosses used to say 'one scientific test is worth a thousand
expert opinions'. Very true.

Up until the last few months "we" did not use the same oil on both
continents. The "best" *normally* speced US oil was not nearly as
good an oil as the spec required by the Europeans. The latest API
spec that's now hitting the US shelves is the first time mainstream US
oils will be more or less the same as the typical oils used in Europe.
I think (purely a guess) that's one of the reasons why BMWs were sold
here with the first 3 years servicing by the dealer included as a
standard practice. It was pretty much the only way to ensure the
right oil got used during the warranty period.

Science seems to be taking a second position to a ridiculous concept called
'the precautionary principle' in so many walks of life.

You're still wrong. There are significant differences. It's true
that you can use "American motor oil" in European cars, but you'll
need to change it more often and will probably have increased wear.
That's no different then the fact that while new cars now specify SJ
oils you can still use the older oil grades if you are really cheap.
As with the prior example, at best you'll need to change the oil more
often and will probably have increased wear.

My dear chap, I live here and consume and retail large quantities of oil, so
I do know what is used here. The standard oil for engines with service
intervals up to 12000 miles is usually just plain dino API SL. This is an
Internatioanlly used STANDARD. As such it is the same on both sides of the
big Pond.

See above.

That's no different then the fact that while new cars now specify SJ> oils you can still use the older oil grades if you are really cheap.

SJ standard is indeed of slightly inferior quality and needs changing
somewhat sooner than SL. However, you should note that even in the early
Eighties there were cars here with 12000 mile official service intervals on
nothing special. I owned several.

As with the prior example, at best you'll need to change the oil more> often and will probably have increased wear.

It is a wonder then that those cars of the Eighties lasted so well. My MG
Montego engine was stripped down due to a misdiagnosis at around 100,000
miles and was found to have no measurable wear. This was using the available
standard oil of the time, I think Shell was used in it mostly, changed at
10,000 to 12000 mile intervals which was about every eight months or so.

If that's the case, you should get a better old car! :-p­ I don't change
the oil that often on my 40 year old vehicle (66 Dodge big-block), not
with modern oil and filters anyway!

Seriously- what kind of car? I know certain AMC v8s had a main-bearing
oil starvation problem at high RPM, but I can't think of a single
domestic v8 that had a chronic bottom-end oiling problem that would
necessitate (or even be helped by) short oil change intervals.
Especially not in the era you mention (circa 1980).

Now, some *modern* engines (eg. Toyota, Chrysler 2.7) seem to have
problems with too little crankcase ventilation and long oil change
intervals, but that's another story.
