The Impreza 2.0i takes all kinds of measures to try and improve gas mileage and cost costs. One way to improve mileage is to program the car to tread the fine line between running ultra-lean and detonation. That's pretty "severe." Another way is to run the thinnest oil possible to reduce friction to the bare minimum. Likewise severe. Neither of these techniques is particularly kind or gentle to the engine.
It will be interesting to observe these engines after 30,000 miles, 60,000 miles and 100,000 miles, eh?
