What;s your other car?

[Spikehaus]

The pistons themselves rotate, and the oily bits cannot be effectively separated from the bits that go bang.

Its what's known as a "total loss" oil system, it continually drips oil into the engine, and the oil gets used up at the rate of about a pint every 1000 miles.

Think maybe all the guys at work must been filling up with my oil!

You have to watch the oil level closely as it can run at 9000 rpm
