Hi all! I had to fill my car for the second time two days ago and was shocked when it took as much gas as the first time but had a dramatic drop in mpg (First tank took 7 gallons for an average of 56.1 mpg. The second took 7 gallons for an average of 39.7 mpg) The dealer sold the car with a "full" tank. I know that most dealers don't really fill the tank all the way so that would mean that my first fill up would require more gas than my second if I drove the same amount of miles. So I should see an improvement in mpg on the second fill up. The first half of my driving with the initial tank of gas was done in mild sunny weather and the second half was done in colder weather. The second tank of gas was used in all rainy cold weather with more short trips than the first tank. I expected a drop in mpg but thought that my improved driving technique would make up for those negative factors. (I had been getting some great results from using the driving tips) I also know that many have warned that the car displayed mpg in usually higher than actual mpg. But the first fill up was spot on and the second was displaying 48 mpg. That's a discrepancy of 8.3 mpg from the car display and a drop of 16.4 mpg from measured results of the first tank. All because of some rain and cold....???? P.S. How do I link my fuelly info?
