Cutting out unnecessary car trips will save you money both in gas money and car maintenance. Instead of coming home from work and then going out to the store that was on your way home, just stop at the store on your way home. Instead of making 4 trips to 4 different stores each weekend, consolidate them into one trip. It’s called trip-chaining…stacking several trips together in one big outing. Each time you cut down the amount of miles you put on your car, you save money.
