Getting less Miles per Gallon lately? If you are getting less miles per gallon than you were 3 or more months ago, and still have the same vehicle and your driving habits are the same, then you may want to consider the following. Our government is not analyzing the fuel tanks that are located at our gas stations, and the level of Ethenol has been raised, in other words, the real gasoline has been %26quot;thinned%26quot; out and thus we get less miles per gallon. Do you really believe that little label on the fuel pumps that says, %26quot;contains less than 10% ethenol%26quot; ?????

So you say that gasoline is regulated more stringently than blood? I worked at a blood and tissue center for over 5 years and your statement is so far off that I must laugh. When did you last see a government test vehicle at a service station, checking the contents of their fuel tanks that are buried underground?

My new 2008 vehicle, with less than 5k miles, and I drive the same roundtrip to work for the past 6 months, and I am getting 6 MPG less per tank now. It has to be the added Ethenol folks.

I do not believe it is water being %26quot;added%26quot; to our fuel for our vehicles are not stalling or pinging like they would with water, but they are averaging 4 to 6 MPG less than the vehicles got 2 or 3 months ago.

In response to the temperature variance...The weather where I am has not changed much in the past 3 months, and my driving habits are identical- to and from work each day. And, my car is a 2008 with less than 5k miles on it. Just about all the possible variables have been considered, and bottom line is: The variables are pretty consistent over the past 3 months, and I, and my friends have watched this very closely, even bought fuel from different stations. We all believe the fuel content has had to change, for no other variable has changed that dramatically, especially to get 4 to 6 MPG less.

People responding really need to read the entire post before making recommendations. My car is a 2008, with less than 5k miles, serviced at 3k miles with oil and filter changes, tires rotated and air pressure regulated. All the variables people have mentioned, such as temperature, driving habits, and vehicle condition have all been a constant, in other words, there are no other reasons for the drop in MPG other than the fuel itself, and it must have more additives than it had 3 months ago. 25% 5 Votes

It%26#039;s basic physics. Gasoline expands at higher temperatures, meaning that in warmer weather you will get a lower mass of gasoline for a given volume. Because it%26#039;s the mass, not the volume, that dictates the amount of energy your mpg will be lower in warmer weather. Compounding the problem is the fact that warmer air is less dense, meaning that most cars run rich during the summer which can be less efficient.

FYI in Canada all gas pumps are corrected to the standard temperature of 15C, meaning that in warm weather you actually get more fuel than the pump indicates. That%26#039;s why a fillup in the summer will show a lower volume than the same fillup in winter. 5% 1 Vote
