Well, 2 major events this week..
1- another tank done 402.8 miles for 55.80l giving 32.82mpg.
This was an odd tank- lots of traffic early in the week, then extended idling for thermostat change and bleeding of coolant system- followed by a "spirited" blast home
2. Service carried out- air filter/oil filter/oil (Swapped to 5W40!
) and new thermostat/coolant
car running better than ever, better cold start, better heat gain when cold, and now gets out the "blue zone" on the temp gauge-so no over fuelling!
Old thermostat at top, new at bottom
