The first days of proper cold temperatures and I noticed that my temp is now sitting at one bar above 60, down from 1 above 80 as it has been all through summer. Is this a sign that my thermostat is on it's way (gone!) out?
If so, is it an easy diy repair? If it is, am I looking at MB for the new thermostat and is it a MB sourced part only?
Interestingly, my (computer) mpg has suddenly fallen from approx 44-46 for the home to work journey down to 38-40. Is this likely to be a consequence of the colder running engine or are other factors at play? I am trying to remember if this is the first tank fill without Millers in so it might also be that although other threads appear to poo-poo the idea of additives increasing mpg.
Thanks
Dave
