I too am & have been wrestling with the decison to try to keep the
93 going vs buying new while we still can.....Obviously, it's a
decision that we can all only make for ourselves. As pieces seem to
be falling off my car at an ever accelerating rate, my car is making
the decision for me ;-(
We're discussing tying the new EV purchase into a vacation and
buying it there and driving it home (if we do our usual "visit the
family" trip out west) or driving around Europe and shipping it home
(esp attractive if we get some of the Europe only stuff). Given the
modern engines & oils, how important is the 1,000km breakin period?
There are some who say the period is a holdover from the old days,
and some who even say driving hard when new is a better way to break
in an engine, (though these seem to be mostly motorcycle folk
(Az?)). Two local dealers say it doesn't matter at all, but they
also are trying to sell (slightly) used cars they bought to ferry
their kids cross country to college.
Any opinions?

Break-in needs are mostly a function of manufacturing precision....the more
precision the less need for break-in. Modern engines are more precise (and
oils are better), so the break-in need is less, but this is not an on/off
thing. I would still observe safe practices, which is keep the rpms well
below redline, don't chug the engine and don't cruise at the same speed for
hours at a time. IOW, don't let the rpms get too low, too high or steady
state; mix it up under modest conditions as best you can, at least for that
first few tanks of gas.

(BTW, that's the same technique you should use when warming up a cold
engine. Don't just start it and jump on the freeway....give it a mile or
two of varying rpm on surface streets to warm up.)

Thanks Mike.
That's what I hoped. As I prefer back roads when touring, varying my
speed happens without effort, and the desired intent of a family
touring vacation would be to take it easy--I just didn't want to have
to keep it to a snail's pace! Whichever side of the pond I do this
trip, if I do it this way, I'll factor in a dealer visit at
approximately 1000kms to change the oil.

Most modern engines require very little in the way of a break in.
Like everything else though, this may be a compromise primarily to
make things more convenient on the masses. I personally think that
taking it easy on a new vehicle simply makes sense. There are a lot
of parts that fot together very precisely, and have to run that way
a long time. Giving them a little time to get to know each other
before hammering on them will make them last longer. It also makes
sense to pay a little more attention to things like fluid levels and
temps during the first few thousand miles.

That being said, break in is actually pretty easy. Just drive
normally, (assuming you don't drive like I do normally) don't tow
anything, don't try to set a new world record making it to Idaho for
your mother in law's tupperware party, don't sit in stop and go
traffic, and don't lug it.

Those folks that believe being hard on a motor during break in are
part right... it will break in faster. It will also not last as
long.
