6 Ways Conventional Wisdom Wastes Money
Change Your Oil Every 3,000 Miles
The little sticker placed on the car windshield reminds you to change a car's oil every 3,000 miles -- regardless of make, model or scenario.
But many experts now say the 3,000-mile oil change is dead. Why? New car engines and oil quality have advanced to the point where cars can go 5,000 to 10,000 miles without a change.
"Generally speaking, vehicles don't need to be changed every 3,000 miles anymore," says Tara Baukus Mello, author of Bankrate.com's Driving for Dollars column. "It's somewhere between 5,000 to 10,000, unless they have an engine oil sensor, and then it could be anywhere."
However, don't automatically assume you can push oil changes beyond 3,000 miles.
"It's important to consult your owner's manual for the frequency, the number of miles, the length of time between changes and the type of oil -- and to follow whatever those instructions are," Mello says.
Use Sheets with Sky-High Thread Count New sheets usually have the thread count listed on the packaging. There's a misguided notion that more is better, says Barbara Flanagan, author of "Flanagan's Smart Home: 98 Essentials for Starting Out, Starting Over, Scaling back."Sheets with a lower thread count are better for several reasons, Flanagan says. They can be washed and dried faster, which saves money on laundering, as they take up less space and dry quicker.In addition to the money saved, lighter sheets are better for your skin, she says."You want your body to breathe through the sheets," Flanagan says, "and you want to get your laundry done in as few loads as possible, so the choice of sheets is really important."Flanagan also recommends using waffle-weave towels over the traditional large fluffy towels that Americans tend to buy. Waffle weave towels are also cheaper to wash -- and can even be air-dried, she says."So that really saves a lot of money in the dryer," Flanagan says. "Your dryer is one of the most expensive appliances (to run) in the house."
Keep Ceiling Fans on in an Empty Room
The ceiling fan is a great alternative to -- or accompaniment to -- air conditioning, right?
Not unless you are in the room, says Gregory Karp, personal finance columnist and author of "The 1-2-3 Money Plan."
"(People) leave ceiling fans on in rooms where there are no people -- but ceiling fans don't cool rooms at all, they only cool people," Karp says. "They create a wind chill factor that makes human skin feel cooler. It has nothing to do with cooling your sofa in an empty room."
And in the winter, running a ceiling fan in the opposite direction doesn't offer many benefits, Karp says. In houses with high ceilings, the fans can push the heat down -- but otherwise, they will often create a wind chill and waste electricity.
And the cost can be significant, setting you back $35 per year on your utility bill to leave a large ceiling fan set on high through the night each night.
