Does the winter mixture of gas lose efficiency?

Heck, I'm punch for high 200's, low 300's, put almost 19gal in and haven't seen the light yet. (Thought here: Maybe I need to check the the light tomorrow morning at lamp test when I start to work.....hmmmm) Got 20mpg once, stays around 17 to 19, just like to book said. (Though I am keeping an I on my oil now.)

Doesnt the book say 15-18ish?

My light is random sometimes it comes on when I fill up with a little more than 19 gallons and sometimes it does not. I normally do not trust the light or follow it and just fill up when I meet the last bar by the E.

I think the tank is 22.. I have seen the light at 20.5

22 gallon tank - I also air my tires up to 46 pounds as a normal pressure. Tend to get about one additional mile per gallon out of it at that pressure, but it does make the ride much rougher and noisier. I've got V-rated radials - I'm not sure if I'd recommend too much air on tires with thinner sidewalls.

Yeah, I think the book has it as 22.5, though, I tend to fill the neck up to the top, but not pouring out on the cladding.
Since out temps have been kind of nuts here, teen's at night, 50's during the day, I do try to switch to non-ac-assisted modes of environmental control asap, but sometimes it stays on all the way to work. Thought about trying another route to work, hiway but longer, but too much on my plate to play with the numbers right now.
