Oil freaks who track their cars are well advised not to overfill the engine oil unless you want to over-pressure the crankcase causing a possible AOS (air-oil separator) failure, which is characterized by smoke ~ mosquito spraying style ~ coming from the exhaust via oil entering the fuel/air intake tubes or a possible RMS (rear main seal) failure, characterized by oil dripping from the bottom of the engine where the transmission/engine join. Porsche, and all other automobile manufacturers, state in their operator's manuals "DO NOT OVERFILL" the engine oil and transmission fluid/gear lube. There is a reason not to overfill the engine, flat six or not, and transmission. Ignoring this simple advisory is simply not good advice, especially in a high performance cars that tend to be driven somewhere near their maximum capability. However, for those oil freaks who simply cruise down the boulevard ~ pimp style ~ no worries ~ keep on cruisin. Smoke from the tailpipe of a cruiser is cool, except when you have to replace the catalytic convertors. People are going to do what they want to do regardless, but there is no good reason not to follow the manufacturer's recommendations when it comes to engine and transmission oil levels.

Agree that a quick flush with a power bleeder uses about 2/3 of a liter, but if you don't bleed the clutch line (which shares the fluid reservoir with the brake system), you'll have some residual blue in the system that will eventually tint the (new) gold slightly with (old) blue. Furthermore, a proper dealer flush on cars equipped with ABS/TC 5.3 and PSM utilizes the Porsche System Tester 2 (PST2) to activate certain valves in the hydraulic system for proper bleeding. So if the dealer does a flush correctly, especially using 2 liters of gold to replace blue, you shouldn't see any blue in the reservoir. In my opinion, the service manager didn't watch the tech and the tech didn't do a proper flush. If the fluid in the reservoir is still dark blue, sounds like they didn't do anything but charge for parts (fluids) and labor. This could be construed as fraud. Take the car back and demand a complete brake system system flush, including the clutch line, using the PST2 if required, per the Porsche service manual. Of course, this work should be done at no charge. If you do the work at home and don't bleed the clutch line (or ABS/PSM with PST2) you may have a slight bluish tint in your gold after switching from blue as reported by Loren. Mike, please post back on your remedy.
