So, gas in my area just hit $3.99 a gallon. I think it increased three times this week alone. What to do? I'm pulling out some of my old tricks.
1) Group errands
2) Drive the speed limit
3) Avoid starts and stops that jerk your speed. See a light is going to change red? Take you foot off the gas early, you'll use less gas and you'll use less brake pad too.
4) Using a gas loyalty program. Saving .05 (sometimes .10) each gallon without paying for a shopping club membership.
5) Setting cruise control. My commute is about 1 hour, mostly highway. I set the cruise as soon as I get on the highway and try my best to use it (safely) as far as I can. I saved 12.5% ($4 buck off on my first fill-up after switching to cruise). I'm hopefully of saving at least $40 a month using my cruise and driving the speed limit. Friday traffic makes it challenging (crazy drivers, traffic too heavy, etc.), but overall my use of cruise is here to stay for the foreseeable future.
