I've noticed a pretty decent drop in MPG recently. I was wondering if maybe winter fuel was being rolled out, or if my driving habits have changed that much since I put my Bernie 2016 sticker on my car
Don't know about US. In the UK it's Winter blend from October 15th to April 15th. They have an intermediate blend for most of the rest of the year and a kind of peak summer blend for sometime around mid June to Mid August - art least according to a document I saw from Shell.
Thanks for posting this. I was unaware that much % butane goes into winter gasoline and this explains a few things to me.
The vapor pressure with warming butane may explain a transitory EVAP error code that crops up on my gen-1 car: sometimes occurring only in early springtime when temperatures get warmer.
This also may explain why the OBDIIC&C Gauge A/F parameter reads a value for stoichiometric ratio of only 14.3:1 vs. 14.7:1. [the MTBE, EtOh; C4H10, etc.]
fwiw: info indicates that the amount of oxygen contribution to winter fuel blend ranges up to 28% in some blends.
I recently got my first "trophy" and have heard that I can "reset" the econ meter to start over. Can't figure out how to do that? Anyone have any insight (no pun intended) on how to do that if it can be done???
See attached, which is from my wife's Gen2 Insight. It shows 1070 miles at an average of 64.4 mpg UK, which is 53.7 mpg US. The driving was mainly quite short journeys (mostly under 20 miles) on a mix of dual carriageway (freeway) and urban/city traffic. The car - which we have owned from new -...
I purchased a 2013 Insight back in March that had about 44K miles on it and the car is in really good shape however, I'm not getting the mileage I anticipated. I do practically ALL highway driving and when I filled my tank yesterday, I had traveled 310 miles and the car took 8.1 gallons of fuel...
We drove down from Santa Clarita, CA to San Diego today all the way on Interstate 5. Some of thanksgiving traffic was horendous. For several hours we averaged around 12 mph. The overall average was just over 30. As I reported a few days ago the car is exhibiting a boost in mpg after the...
