Now that summer has more or less gone, I've noticed that the engine temperature on my E320 CDI (W210) has dropped. It was sitting at about 80 (more or less) throughout summer but now sits at about 65 no matter what traffic conditions (although I've not been caught in a proper traffic jam yet). Cruising at 85 mph on the motorway or pottering around town - the temp is 65. Does this seem right? Surely the colder running engine will use more fuel (which has never been that great on ours. I babied it from Sussex to Bournemouth and just about scraped 40 mpg).
Any opinions appreciated.
