There are many suggestions on the internet advising you and me on how to save money on gasoline but many of them are moronic. One that I found had as its first suggestion... "don't drive" and another one was to relocate your dwelling closer to where you work. It would save you some fuel but do you need me to tell you that? Another bit of advice that I saw from one of my fellow internet bloggers was
"use lower octane, it's cheaper!" DUH! I am going to attempt to give you some tips here that you can actually use and that are not things that any driver with enough observation skill to have passed their driver's tests knows for instance "don't use sand paper for an air filter" and such.
SPEED: There is a lot of math involved in this. But fuel dissipates exponentially the faster that we drive and even more so when we get rockin' above 65 mph. The maximum speed for gas mileage is the lowest speed in your highest gear which is most commonly in the zone of 40-50.
STOP AND GO: Take off slowly from a full stop. I know it isn't fun especially when you want to race that "Beemer" in the lane next to you. But actually this will provide the
biggest gain in gas mileage.
SHADY DEALINGS: Park your car in the shade. Gas actually will evaporate right out of your tank in hot temperatures!
CARPE DIEM: Seize the best times to buy gas. Gas is statistically less expensive on Wednesdays. Buy fuel three days before a Holiday and avoid the greedy "bump" that oil companies always beat us with on days that they know will have heavy traffic.
IN A HURRY? If you are not in a hurry to get home after work then avoid rush hour. It will save you money on gas and give you a happier attitude towards life. But you already knew that.
