Oil change cost has went to 1/2 price by getting Rotella T6. No, I hadn't got oil analysis done. I'm sure I could more than double from an oil additives still present basis. At my driving distance, it's still only 2 changes per year. Car isn't my daily driver.

I gotcha. Yea, at 2 changes a year, who cares.

I've been trying to figure it out, too. My guess is that the filter was blinded by sludge causing the pressure on the outside to skyrocket. I would have guessed that this car has a bypass valve to allow oil flow in case the filter gets clogged, but I don't know. Assuming not, the oil pump could create some very high pressures, which could collapse a clogged paper filter. Without a bypass, bearings, lifters, and turbos could starve for oil until the filter actually ruptured.

The shop said the sensor had cracked and was filled with oil. Did high pressure cause this too?

At any rate, car seems ok now, but I got raped by the shop. They charged me $150 for diagnosis, $20 for the new sensor, $190 to install it, and then performed two full synthetic oil changes with filters. The total was $727!

There is an oil filter bypass valve. Your crushed filter is purely a stupidity of the installer or a wrong part which will fall under the first category:

Thanks, Yozh. This is what I would have expected, but did not take the time to research. Now I can't think of any scenario that crushed my new filter and broke the pressure sensor. Can you?
