Re: Laguna II 2.0dCi poor mpg?!?


After getting the EGR cleaned and everything else given a clean bill of health I decided to run a longer test on the MPG figures by setting up a spreadsheet (a bit sad I know). Over 3 months I recorded the mileage and entered the diesel I was putting in the tank. This showed a MPG figure of over 40 while the computer in the car was still showing me 34. I realised the car computer was displaying USA gallons rather than UK. If you multiply the figure by 1.2 this gives a rough guide to the actual MPG you are achieving. Don't know if this is common on Laguna's but the maths worked out on mine. Hope this is the case for yours too.
