Check all the fluids and tyres thoroughly.
Get a good night's sleep beforehand (although better IMHO to split the trip
over two days).
The UK TV program managed to drive and Audi A8 diesel from London to
Edinburgh and back (~800miles) on a tankful, but this probably means
cruising at 56mph (90kmph), which makes for even more time behind the wheel.
The most economic speed is normally 56mph. On big BMW's the auto boxes
change up into top at this speed in part because this is the speed that EU
consumption figures are given for.
If you go slower a lower gear will be selected, giving more revs and higher
If you go faster then you just use more fuel.
Interestingly on the 735i that I had cruise control on, it used to do better
with cruise set than with me holding a steady speed with the accelerator.
thanks everyone, for posting ;-)
turns out- i'm *terrible* at articulating a question.
gas/petrol prices, gas mileage, stops for gas, stops for breaks, etc
weren't even my concern(s).
every car has got a capacity, right? a capacity that says 'ok, it can
go only so far/long (distance-wise and time-wise) before it needs a
solid break'. that's the capacity i was talking about when i was
talking about my 99 323i ;-) it's an old car, has 78K on it, and is
generally well maintained, but y'know, i've never taken on such a long
trip before, so i thought i'd ask. i guess a 900-mile trip is nothing.
thanks again for sharing your experiences and adding your thoughts to
my concern. i definitely feel much better now ;-)
btw, go through this link when you get a chance (i'm sure it's been
posted elsewhere too, but it still gave me a kick; there was another
link on bbc that i can't find now- that's even funnier, htis one is
No, not really. It's acutally the driver who needs a "solid break," not the
car. Casual hwy driving is very easy on a car and it can pretty much go on
forever if not for the fact that you need to add gas, use a restroom, or
feed yourself. The startup of a cold engine is what generates the biggest
wear and tear.
Ehh.. it's not really that old and 78K miles is nothing if it was well
maintained like you said it was. Enjoy the drive.
I wonder what this line in the article is supposed to mean?
"AT THE END of the road, when the engine was taken apart, Mobil's
engineers discovered that the wear measurements were the same as the
Do you think it meant the measurements were within build specs? or that
they had reached the manufacturers upper wear limits, or just that it
was within the mfr. wear limits?
that was the funniest $hit i ever read.... lolllll
this thread is still alive? what the heck are some of you guys talking
up there? i have no clue.
nothing can go for a million miles. i mean, nothing that's
mass-produced and commercialized like the bmw. a really high-tech
scientific, made-for-space bmw? maybe? come on guys ;-)
