Just got this in the mail. Luckily, I need an oil change anyway. Here's the juicy part:
Based on your vehicle indentification, your vehicle may either require securing or replacing the crankcase ventilation hose to improve engine performance. Additionally, all vehicles within the same VIN range equipped with manual transmissions will require a new oil trap to be installed. The new type oil trap was introduced during the 2004 model year which, in some vehicles, could cause abnormal oil consumption under certain driving conditions.
