I shot them off an email yesterday, and they replied that they have three varieties of crank scraper for the Opel. I'm going with the all-metal 'dual' scraper as opposed to the teflon version (it's a street car after all).
Hey, if it reduces just 1 hp worth of parasitic drag at 65 mph, it will have a measurable effect on the mileage!
