At one time if you bought a brand new car you might be told to 'run it in' first. At one time the tolerances of vehicle engines were not as precise as the modern vehicles we drive today, and would definitely require you to not drive the vehicle too hard or fast for the first few hundred miles.
This used to be the responsibility of the new owner, but most modern car engines either don't require running in, or this has already been done by the manufacturer before the vehicle leaves the factory.
How do I know if my new car needs running-in?
Generally your car dealer should be able to tell whether a running-in period is required. Thanks to advances in lubricating oils and engine technology this is often not the case however. Check your new vehicles operating manual too for any information on this though, the dealer may not necessarily be familiar with all the requirements for that particular model.
If the engine does need to be run-in
If your car does need running, or you feel that you want to 'break in' the cars components gently, these are the kind of things to consider for about the first 1000 miles.
Start with gentle town driving. This will allow all the major engine and transmission components to 'bed-in'.
Brand new tyres may initially have a thin oily coating on their surface as a result of the manufacturing proces. This may affect the vehicles handling in the wet until it has worn off.
Try not to accelerate or brake rapidly. Take all manoeuvres smoothly, which is actually good driving practice anyway
If you have a diesel engine, try to avoid exceeding 3000rpm but don't be afraid to approach it
If you have petrol engine follow the above advice for the first 600-700 miles and then increase the limit to about 4000 rpm
Try not to put excessive strain on the engine by misusing the gears
Check the oil and coolant levels every week. Oil consumption may be high for the first 5000 miles or so but should decrease after this period
