I have just filled up after my first 50 m.p.g. tank this year. Summer gasoline, with its higher energy density, is back, the air is warming and there is less rain (and no snow) to hold the car back. It's good to put the 44 m.p.g. tanks of winter behind for a while!

This tank was dominated by my commute, which is 13 miles and 25 to 30 minutes each way. It is partly on two-lane roads through residential areas with 30 or 35 m.p.h. limits and partly in "Route 1" conditions, that is four lanes and 45 to 55 m.p.h. limits but with frequent lights, turnoffs and other reasons to slow down. So, it is neither "city" nor "highway". There are plenty of ups and downs, almost nothing flat. In my Mazda 626, I would get 32 m.p.g. in the same circumstances.

By the way, my mileage figures are always corrected for the optimism of the Consumption Display. By tracking the gas I put in I have figured that mine is about 4.5% off. The display reading for this tank was 52.5 m.p.g.

For the next tank, I'm going to try to avoid "Consumption Display Obsession" by switching the screen onto something else. If I keep track in my head of general conditions and any abnormal journeys, I might be able to guess what affect CDO is having on my economy.

Geez Graham. It took you long enough to get to the greater gas mileages. We had our 53 mpg tanks last month and now with winter returning to New York again, I am back down already to about 45 mpg.

Interesting thing on my side is that the displayed mileage seems more accurate in the summer weather.. hmmmm

Have fun!

I'm starting to get up near to 50 mpg now too(except when my wife rides with me it drops because of the air conditioner :). However, isn't it a little less reliable to do manual mpg measurements because of the 'plastic bubble' in our tanks that depending on the temperature it is outside when you fill it up at can hold more or less gas?

Long term manual m.p.g. measurement gets more accurate as you put more gas in. I've put in more than 250 gallons now. Suppose there is a 1 gallon variability in how full I get the tank. Over one tank, that's a 10% error. But, over 250 gallons it's only 0.4%. So, I know to an accuracy of 0.4% how much gas I've used to drive my 11,500 miles. By keeping track of how much gas the consumption display thinks I've used, I know it is about 4.5% off. If I assume it's always off by the same amount, I can just correct its readings on a per-tank basis. I get the accuracy of long-term fill-up monitoring and the responsiveness of an instant display!

Thanks for the tip on how I could manually judge it with better results.

Hard to imagine that in a few years our sweet rides will be getting up to 80 MPG or so. Congrats on your first!

I have an 02 and not until this Christmas did I get my personal best. I needed to drive from Savannah to Myrtle Beach and decided to take Hwy 17 to optimize fuel economy. On the 50mph straights, I did just that and when the road doubled in lanes and went up to 60mph, I did only 52mph. I was not slowing anyone down in the tight lane and enjoyed the relaxing pace. When I got to Myrtle Beach, the MPG registered 61.3, my personal best. I doubt that I will ever get that again unless I take the same route in the summer when the ambient air temp and battery are warmer.
