Hello, since yesterday I have been driving regularly with my convertible 2.6 out of 96. I noticed that the engine temperature remains normal in the stand or when driving slowly, i.e. 90°. From road speed it sinks to below 60° just above the stop of the display. It also lasts forever until it is warm again. The oil temperature is usually around 70° (schanted, the display is so inaccurate). Is the normal by the wind or is something broken (and what)
