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.
Hello, Its been a week i am driving this 2011 Honda insight and feeling little let down. Its MPG is 35-36. Which is bit of a joy killer after spending more then what i was suppose to just because it was a hybrid.
Done full service, Tyre pressure is ok and driving in city and motorway without...
Tue 28th Jan. 2009 SE. 4 degrees C (39.2 F) South East London to West London (1hr), then M4 to Cheltenham (2hrs), total 119.2 miles. Average speed 39.73 mph. Less than £10 for a journey that previously cost £28. Pleased.
Loving my 2009 SE G2 more and more after nearly three weeks. And... it's become clear I've been driving badly since 1976, which is a bit of a shocker. How remarkable is a car that not only gets great FE, but also teaches you how to drive properly??
Every day's a school day and I'm really...
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???
