Hello chaps - while debating the eternal question of 997 Porsche ownership, we have procured a new mazda 2 tamuda for the missus. Delivered next week, brand new 12 plate.

Led to an interesting question having never owned a new car... what's the best advice for running it in? She does a lot of school runs and I do a bit of motorway, so just looking for the right way to do it. Being a 1.3 with 86 raging japanese horses I am guessing that thrashing it isn't smart! Any advice appreciated, want to bed the engine in over the first thousand or so miles and not damage it.

Cheers!

few doughnuts and power slides around your local car park should be enough I reckon

If the handbook doesn't tell you to do anything special, I'd just drive it normally, personally.

Don't labour the engine too much either - I seem to recall this being as bad, if not worse, than giving it a bootful when it's being run in.

No need to observe a breaking in process really these days, mixed driving including labouring and revving in the early life of the engine is beneficial in the long term in minimising oil consumption and increasing cylinder compression.

Quote from Renault engineer - 'warm it up properly, then show it who's boss'. Not sure if the same thing applies to Pork though. wink

You dont really need to run new cars in these days but if you want to be kind to the engine run it gently for the first 1000 or so miles. The garage will probably want you to book an oil service once it has run 1000 miles and they will change the oil and the oil filter. After that feel free to drive it like a hire car.

Dont think there is any right or wrong answer, so many variables and outcomes, one that is better performing may use more oil and one that is run in too gently could I suppose be even worse as it never really beds in.

Superb advice, thanks chaps. Little 1.3 so don't want to explode the poor thing :-)

Have to say, fantastic little car, 0% vat on Mazda right now for a really nice shopping cart!

Don't some engines get run in at the plant before being fitted to the car?

If you mean shoving 2 litres of regular in whilst smoking a fag then spanking it 1/2 a mile onto a transporter then I suppose so.

Wife is using a Toyota Auris 1.3.

I used it on the motorways for the first few 000s of it's life and gave it a bit of stick if I'm honest..

At 20k it feels much more urgent than the 5k loaner she got during the service.

My advice: just give it some and take it back under warranty if anything fails.

Typo, now edited. I did of course mean increasing engine compression by bedding the piston rings into the bores as early as early and quickly as possible. The theory goes that the bores don't get 'polished' like they can using a soft break-in process.

By short shifting but with a lot of peddle and hills.

I'd check the owners manual, see if it says anything particular, but the days of the "Please pass, running in" sign in the rear window are gone i reckon.
Only New car in the family here was the e92 m3 which came with strict instructions, as did my mates rs4. They're performance engines so may be different but no harm taking it easy for 1000-1200 miles.

hehe Anyone worried about running in their new car - Take a trip up to Grimsby docks and watch through the fence as an endless stream of Yaris's and Nissans do burnouts across the big carpark onto the big transporter ship!

The more i've nursed a car, the worse it's been. My advice is to forget the whole running in process. Just don't be too gentle with it.

Hit 1k miles in our VW last week - mpg dramatically improving and it feeling looser - thank feck for that! I've kept it under 3.5k rpm (it's a diesel...) just to be safe.

Yep, drive it like you stole it.

You would be surprised how much 'headroom' cars have.

The A500 has been driven sternly and it is certainly improving as the miles creep up.

Also, its amazing how a brand new car can amass more than 10 miles on the clock when you take delivery!
