Is there any way to get the normal (non-winter) gas? I rarely start driving on a cold engine.
On that note, it takes almost 5 minutes for the engine to warm up in this 25 degree weather. Is it better to drive it cold since i'm not getting any "mpg" while sitting there at 0 mph? Or should I warm it up like I have been doing? I thought that colder engine uses more gas.
