Getting to know my 456GT. My car is garaged at a 15 degree incline, where I typically park it nose first. (The rear-end is backward sloping.) I have noticed two things: a) there is a dark liquid residue of what appears to be oil at the edge of the mufflers tips. b) once I start the car, the fuel gauge reads empty (and even the reserve light goes off) for several minutes, with the tank relatively full. This situation returns to normal after approximately five minutes of warming up. Are these conditions normal? Advice and reassurance greatly appreciated.
