[grymanti]

I'm new to this forum and a bit overwhelmed with the escalating fuel prices. I've recently put in a K&N air filter,ngk spark plugs,tire press is 40psi,fully synthetic oil,will be getting a fogwarmer,have reduced my highway speed to 55mph,and have done away with jackrabbit starts.I drive an 05 Kia Amanti, if any one has anymore ideas to squeeze out more miles to a gallon please let me know. thanks
