When you take your vehicle in, keep these things in mind. I would not necissarily refer to this bulletin when you take it in, simply state that you have been keeping track of oil consumption and give them your findings. Dealerships seem to dislike web forums as they are commonly misinformed. Often times people think they will get xxxx if they simply go in and talk about a bulletin and how it applies to their vehicle.
Personally I don't think there should be any measurable oil consumption if a vehicle is running and maintained properly, but that is just my own thought, so take it with a grain of salt.
..."Important: This rate only applies to personal use vehicles, under warranty, that are driven in a non-aggressive manner and maintained in accordance with the appropriate maintenance schedule,
with less than 58,000 km (36,000 mi), or driven at legal speeds in an unloaded (for trucks) condition..."
..."Aggressive driving and/or continuous driving at high speeds/high RPMs will increase oil consumption. Because this may not always be an everyday occurrence, it is hard to determine exactly how much the oil economy will be affected.
A higher rate of oil consumption is normal for vehicles equipped with manual transmissions that are driven aggressively. By "aggressive," we mean operation at high RPM (3,000 RPM to redline), with frequent use of engine braking (using the engine to slow the vehicle).
Vehicles that are driven aggressively may consume engine oil at a rate of up to 0.946 L (1 quart) every 805 km (500 mi). This is normal for a vehicle that is driven aggressively. No repair is necessary. This characteristic does, however, require the owner to check the engine oil level at sufficiently frequent intervals, especially when driving aggressively, to assure the oil level remains within the recommended operating range. As the Owner’s Manual recommends, you should check the oil level every time you get fuel..."
