I have a 99 M-Roadster with about 1100 miles. I checked the oil today (following the manual instructions) and noticed that the oil level seems to be right in between the 2 indentations. The manual says that the capacity in between indentations is 1 liter. Should I top it off or should I wait until the leve dips closer or is on the lower indentation? Does this affect the ability of the engine to provide oil during high-speed cornering?
