Re: Renault Laguna II - Phase 1 - Engines - Average MPG from 1.9 DCi Engine
My Megane Classic Expression + 1.9 DCI lies to me.
I continually under-estimates the fuel consumption by at least 10%.
I commute almost 100% on the motorway about 90 miles a day.
In summer the trip computer claims up to 55 mpg if I cruise around 65 mph.
In winter, same driving style provides 43 mpg accoring to the comp.
In reality - at the pump when filling up - I may see 45 mpg in summer and 40 mpg in winter.
When I compare the trip computer's consumtion in gallons to actual litres bought I am 10% to 15% out all the time.
Currently in Fizzynix's garage:
