not so much either of those. It's more of a situation with location of the exhaust pipe being close to the oil pan and the turbo cooking the oil on top of it causing sludge build up in the pan and head. It ends up restricting oil flow causing catostrophic engine failure. SAAB NA has been covering replacement engines on ones with a complete service history upwards of 100k for sludge failures.
I'll take some pics of the fuel door sticker later today after the wife and daughter get back from the childrens museum with the camera.
