Great if you are the owner of a new BMW and don't want to void your warranty. Try pricing
oil for an Enzo Ferrari (don't even ask the price of a filter)...
Mobile 1, Redline, Royal Purple... Mobile 1 is easy to get. Yes it may break down faster (at 500 degrees f.) than Royal Purple (but at 500 degrees that small you are smelling is molten bearing material).
(For those of you that don't get Car and Driver or otherwise have access to information on the new $659,000 Ferrari Enzo, you might be amused to know that in order to maintain the factory warranty, owners are required to use the factory specified
oil:
Shell Helix 10W-60
Synthetic - $60 per US quart - engine holds 12.2 quarts - total cost for
oil change: $732 US. Other consumables:
One set of front carbon-ceramic brake pads - $6000
One set of front carbon-ceramic brake rotors - $24,000
Sometimes you begin to think that they charge this much for stuff not because it actually costs that much, but because they can and the owners will pay it.
