Read the parallel topic where fellow member was too busy to do the service and 8,000 miles past due the sludge clogged turbo oil passages with predictable consequences.
Per my knowledge such overdue should not create sludge, since the same cars in other parts of the World have 40,000 km intervals, but any car dealer selling such a car without changing the oil has to be an idiot. Who knows what else they can come up with.
On the other hand I am strong believer in the vehicle inspection and usually ignore the records, especially buying high mileage cars. Just because somebody charged the owner for replacing oil filter, doesn't mean he actually did it. More than once on newly purchased car the oil element was "extra crispy" what would indicate staying on the engine for a very long time. Yet there was a receipt for recent service.
If you are making an offer on the car -you should be the one taking it for inspection. I would make a solid offer contingent to the car passing the inspection. If the inspection find something wrong, the seller has to reimburse you for the cost, or refund your inspection cost. Taking the valve cover or other cover off -to check for sludge would also be one of my requirements.
