Where do you live? In the MidAtlantic US we have had 10% Ethanol year round for years. The winter fuel blend here has the same ethanol content as the rest of the year. It does however result in a bit worse MPG which combined with the direct effects of the cold (cold engines use more fuel till warmed up etc etc) really makes for a noticeable drop.Every year, going into winter, the Addition of ethanol results in a drop of 10%. Now, we will have ethanol year round, so 10% loss permanently.
I wouldn’t assume the drop is only because of ethanol. The cold weather itself increases gas consumption every year.Every year, going into winter, the Addition of ethanol results in a drop of 10%. Now, we will have ethanol year round, so 10% loss permanently.
Some fuels contain less energy than others.
Using oxygenated fuels or reformulated gasoline (RFG), for example, can cause a small decrease (1%–3%) in fuel economy.
Most of the gasoline now sold has a small amount of ethanol in it—up to 10% by volume depending upon the region. Using gasoline with 10% ethanol decreases fuel economy by 3%–4%.
The energy content of gasoline varies seasonally. Typical summer conventional gasoline contains about 1.7% more energy than typical winter conventional gasoline.
Yes. My MPG dropped by about 10% about 2 weeks ago. Probably winter fuel blends hitting local station tanks. My dad in PA has also reported this to me with his hybrid. We're both getting 36 or so, down from around 39-40.Now that the outside temperatures are dropping (at least here in Canada), do you notice a difference in gas consumption for the Hybrid?
