This is true but what does wear out is the additive package added to the base oil (ie detergents, anti-foaming agents, etc). At the end of the day, I use Mobil 1 in the E39 and Mobil 1 Delvac in the Duramax. I change at 4500 miles or so in the 528 (halfway through the SI lights) and 5K in the truck because OIL IS CHEAP AND ENGINES ARE EXPENSIVE.

Probably true for the BMW but the diesel runs dirty.

Performance loss also is a consideration when deciding how long to use oil for. Same as considering if spark plugs are still good because emissions haven't increased, or if plugs need to be replaced when the power drops off. Has anyone dyno tested engines with fresh versus 5k, 10, or older oil? Skipping an 'oil service' saves more than the cost of a quick dyno run, so will someone on the other side of the issue offer their car for testing? With what it costs to add a few HP to a BMW does it make sense to deliberately take a few away?

Umm, can anyone cite cases where engines broke/wore out because of extended oil changes and what the intervals were? Like many others I can quote personal experience of engines performing just fine on 12-15k intervals. Just be interested to hear from counsel for the other side. Not looking to rubbish others firmly held opinions but trying to find an objective view. We're not talking B****i here so it should be possible. FWIW my feeling is that cold starts and extended stoppages (allowing lubricants to drain down from the top end) are significant factors in engine wear. A case could be made for frequent changes when an engine only gets short mileage use and never gets hot enough to evaporate off petrol contamination in the oil. Over 50 miles a day and things get better. The trucking industry can achieve intervals of 150-200k km between oil changes and they are every bit as concerned with engine life due to their tight margins.

Most of these over the road trucks that run extended oil changes, also run multiple large oil filters. Many of them are setup with by-pass oil filtration systems. They can grab sub-micron particles. Oh and Amsoil sells them...I do like to stir up a flak battle now and then:-) I like Amsoil, I don't profit from it.

Oh yeah, a good way to make a little money is to start with a "classic" car and a lot of money. If I spent that much on restoring that thing, I would keep it.
