A well-educated man towed his new company car to the shop, said it quit on him and won't crank over. We found the engine seized up, not a drop of oil in it.
It had 18,572 miles on it. The inside of the engine had two inches of sludge and the original oil filter on it. He said he thought all the fluids were good for 100,000. His company fleet maintenance guy didn't think this was as funny as I did.
There is a huge risk with extended oil change intervals. Some car makers suggest intervals of 5,000 miles, some suggest up to 12,000-15,000 mile intervals. Today's oils will still have much of their original configuration well past 7,500 miles. The problem with extended oil changes is not the performance of the oil, it's that no one is checking their oil level.
