Cars do need a running in period
Discussion
There was a topic on here not so long ago about do cars need running in and oil and filter needing to be changed after a 1000 miles or so, well yes and proof of a car that we have had in the garage this week. Chervolet kalos 08 suspected timing belt snapped took the covers off timing belt in one peice with no damage to the belt tryed to turn the top camshaft over sezied solid, cause never had a oil or filter change since new took the head off and found bits of metal around the camshaft and valves, also looked like there was a blockage of some sort aswel most propably metal in the oil ways.
So result in a £1200 bill for a second had engine and to be fitted only done 21000 miles.

21k sounds like a long interval between changes. I guess I'm old fashioned with my 6-monthy changes, but then again that's what you get with cheap-o mineral oil!
I know fully synthetic oils last a lot longer but you would think 2 years / 24k of hard driving would allow them to build up a good content of fuel, moisture, carbon and acids. Makes you wonder if the new craze for 24k oil changes is more of a sales ploy than anything - after all, once the car reaches the end of the warranty will the manufacturer really care if the engine has suffered increased wear?

Don't those have the GM Family 1 engines, same as the Vectra/Astra etc?
If it is, then 2 years and 21k is fine for an oil change. I suspect if the engine is as bad as you say, there's something else wrong, and not just lack of oil change.
No i beleive its the same as the old kalos not 100% sure though, when we took the head off the camshaft had burn marks on it so either something blocked the oil ways or ran low on oil at some stange, but when we had it we checked the oil and it was between min and max, but what had blocked the oil ways only thing we could come up with was that there were bits of metal in the oil when the car was in its running in period and the engine was wearing in.If it is, then 2 years and 21k is fine for an oil change.

Do you sell Porsche parts as well Josh?
Not as yet! 
Most recent engine I priced superceeded from being a complete engine to a short motor at £3200 and a head at £1400.
Porsche bits certainly aren't that cheap
.
But if you buy a new car you can change the oil whenever you like and remove the possibility of it not having been serviced properly.Nothing to do with running in and a lot to do with shoddy quality control at the factory.
No oil and filter change will catch metalic particles that were in the engine oil galleries AFTER the oil filter.
Running in is largely redundant these days due to modern honing processes and being able to control the surface finish of the bore.
