Unfortunately, ever extended service and oil change intervals are not specified solely by the engineering divisions of car manufacturers, but are more normally the result of what the marketing division says is necessary to sell a car; it is much easier to sell a new car if an unsceptical car buying public can be persauded that it can be run on a shoe string!

So, if you value your engine then get the oil changed at the end of the running in period and ignore the extended oil change intervals and double up the frequency of oil changes. These will have to be paid for on top of the usual TLC cover.

Someone will, no doubt, say that engines are run in on benches at the factory; I've been to engine manufacturing plants and the engines are run for a very short time, just long enough to test it for power, emissions and water/oil tightness. Running in would take very many hours and there just isn't the time, the space or the profit margin to do this in an engine plant.

In addition, although modern synthetic oils do last longer, they work really badly when they are carrying a heavy load of metal particles!

It's your engine, you choose....

Tigger.

conspiracy theorist. I wonder what engineering school you graduated from. Of course you could just be someone who owns lots of stock in a motor oil company. I've yet to hear of any car engine being damaged from metal particles if it was driven properly and had the car serviced when appropriate. Now if you pay any attention to *ahem* professionals like the two brothers known as Click & Clack who have a website, newspaper column and radio show and own a garage and dispense fair advice with mucho years experience you'd know that there's a good reason cars don't need their oil changed as often. Cars don't require undercoating to prevent rust through either, but I'll bet you get that done right? No? Well why not. Certainly you don't trust those sneaky suckers who tell you when to get your oil changed that you can trust them about the rust.

Me thinks you aren't speaking from experience, but are promoting falsehoods to enhance your online persona.

Ahhh I see you are in sales. That explains a lot.

While changing your oil often certainly won't hurt the car if you drive it properly you won't need to change your oil any more often than is required, but you are welcome to join the "car will die a most horrible death" group and do it every 3k. Now I'm not in sales(repair subs actually-no not the sandwich), but don't you think it would have gotten out by now if the mfrs reasoning wasn't based on valid engineering and not *ahem* a ploy by the "sales" department?

Do you sell motor oil by chance, Tigger?
