ive seen this before here where people talk bout covering the grill of the i2 in winter time, and they actually get more mpg
i live in socal and its been pretty cold here lately, also my mpg is dropping, i was wondering if this really works, how cold would it have to be for the car to be safe and not have problems if i block the grill
mornings get as cold as 50 and during the day it stays 60 but never hotter than 70
is that not cold enough?
should i just forget it?
