The lie-o-meter is always optimistic. If you want more accurate real-time numbers, get a Scangauge II and calibrate it to your car.Wow, I am glad most others are getting this mileage. However I have not been so lucky.
My GSW 6m had 193 miles on it and presumably a full tank of diesel when I picked it up in El Paso.
For a week or so I drove it my usual commute which is about 60% city and 40 highway. I go early enough that I rarely hit more than two or three lights.
In my 2010 Jetta I averaged 42 mpg in this scenario.
I drove the Golf on a road trip, 1020 miles each way.
All interstate, varying speed between 75 and 82.
It was windy but I don't believe that would kill my mileage down to 39. I had two adults, two children and my wagon was stuffed full of cargo. AC on.
Last year we did this same trip, same weather and load factor, and our average in the Jetta was 41.
Now the car has 3072 miles and today I calculated 39 mpg when the car said 46 since last fueling.
I expected this kind of mileage until it's broken in more, but I am disappointed in my numbers compared to others.
I am happy however that it's better than most petrol burners. I'll see what happens with this tank, under my normal driving conditions.
Why is my car's mpg calculator so far off?
My lie-o-meter, through six fill-ups, has been 3.5 mpg (6.5%) optimistic.
