Question Summer Fuel?

Anyone when the official change from winter to summer fuel is? I just filled up and was up to 14 mpg which is better but not the 15-16 I used to get.

Another thread had F250-Newbie mention the summer fuel...

Just Wondering

To be honest, I'm assuming that the summer fuel is here because of what I noticed in the slight mpg increase. At the same time, though, I also switched back from the DK White to the DK Gray and add in a fuel system mod to balance fuel pressure in the rails.

I'm not sure of the date either but am pretty sure your mpgs will improve even with winter blend in warmer temps.

Yeah, I would hope that the 14.2 would be beacuse it has been warmer and the summer blend will put me back over 15.5.

Did you just change your screen name from F250_Newbie to F250_? If not I was not trying to be a jerk.

Scott, Don't worry... no problem, and yes, the ID has changed.
