Is there any longer such a thing as 'running a car in?' I know one should still go carefully with the engine at first,but beyond that does anything happen to the car which will be noticeable as one puts on the miles?

I ask the question because my A Class has now done 8,000 miles. Is it 'run-in'. Or is there more to happen with more miles?

I think that you are past your run in stage by now,,it just means driving lightly for the first few K miles,,it is said that they go on loosening up till 30k miles,,.

Once you get past that it is on the way out :rolleyes::rolleyes: only kidding :D

Its been said that VW/Mercs continue to run/settle in till way past 50K.. Not sure how true this is though

The initial advice with many modern cars is to run them pretty liberally from the word go, but to avoid either revving the engine too hard, or letting it labour.

If you have been going gently so far, I think you could now consider the engine to be "run in", although as others have said, it will continue to loosen up and improve for some time yet - especially if it is a diesel.

You may find that it will take a wee while to get used to being driven harder after it's easy life so far - I sometimes think it takes a car a bit of use in the new regime before it gets accustomed to it, but it will settle down and accept your preferred style of use with no problem

It's a quality peice of engineering, using quality oil ................ just nail the bugger !!!!

On Britains roads, I doubt you'll be able to run at high revs long enough to upset it ............. whatever upsetting is ................ I've had many new cars .... and running in is really not what it used to be ........... maybe take it gentle for a thousand miles if you must .............. but 8K .............. I think it's safe to say you can use second gear now ............. lol

The way things have moved on,, back in the 50's you ran the car in for the first 1 or 2 k miles,, it was worn out at 20k miles, so you started all over again. With no motorways it did take a long time to go anywhere, and cars were not used to traveling more than few few miles without slowing down or having to stop. When the M1 opened it was littered with broken down cars,, Tyre blowouts were every where as people were running on re cut tyres then, and they were lawful. The next was over heating steam everywhere, and people running down the banks to rivers to top up the rads.
Lastly the engines seized up as the oil pressure died, the road was littered with pistons and half a con rods where they had gone through the crank case, happy days :D:D

They say that hire cars are some of the best run in ones, lots of different drivers with different styles and very rarely is the engine laboured, lots of banging off the rev limiter but very little labouring.

I reckon company reps cars get run in the quickest, first few miles going home from the office does it nicely;)

Happy days indeed, such occurrences always happened to me when I had, on the rare occasion that is, a pretty young (ish) lady sitting along side:Oops:

I remember my fathers new cars in the 60's having " Running in Please Pass" stickers in the rear window. Of course those were also the days of a "decoke" at 30K-40K miles as well. My mates E Type V12 had a sticker attached to the Rev Counter that said "3,000RPM Max for the first 1000 miles".

It may make sense to run in new tyres and brakes for a short while as often the final "curing" isn't achieved until they are actually in use. With auto gearboxes it is quite difficult to actually abuse an engine these days..

I forgot all about those stickers "running in" it was almost a status symbol to show that you could afford that

My first car in 1965 was a 1946 Morris 10, Series M. Cost £20, insurance (Road Traffic Act Only - RTA) cost £10.

I put a sticker in the rear window "Running out, please pass".

As bits failed, and I had no money, I worked around them. Eventually I was driving a car which had: no handbrake, no silencer, no indicators, a battery which was OK by day but could not hold charge overnight, no rear bumper, intermittent wipers (years ahead of its time), no air filter, crumpled offside wings. And yet no one seemed to mind. I parked in gear on a hill overnight and bump started it first thing in the morning.

I managed to hole the petrol tank in the Scottish Highlands and a local blacksmith repaired it for me in an hour for £2! (I withdrew to a safe distance!). An oil pipe failed at one point, so I topped up the oil with water to get home!

The final insult was when a brake pipe failed (it had been braised by a previous owner), so I got rid quickly.

Only then did I discover that RTA insurance meant that I would have been liable for damage to other people's property! - it was not even TPFT!!

Motoring used to be an adventure in those days. I never had the problem of "Running in" until 1971.
