This depends on the make and model of your car, but it's a good rule of thumb to change your car's oil at least every 5,000 miles. Some cars will need a change after just 2,500 miles, and some vehicles can run longer. If you really, really wanted to, you could run your car without oil at all, but it's not a good idea.

Months with 31 days are January, March, May, July, August, October and December. February only has 28 days and 29 days in a leap year, and all other months have 30 days.

All living things need to eat, so cooking is one of life's most essential skills for us humans. To cook pasta, just let it sit in boiling water for about 10 minutes. Exact cooking times vary from about 8-12 minutes, but if you drain pasta after boiling it for 10 minutes, you will have cooked edible food.

The first step in the Heimlich maneuver is actually a series of steps assessing the situation. Who is in trouble? Is 911 en route? If someone is coughing, they may eventually dislodge whatever they're choking on, and the maneuver won't be needed. If it's determined you need to do the Heimlich, the first step is to get the person standing upright.

Election Day in America takes place on the first Tuesday after the first Monday of each November. The presidential election only takes place every four years, but there is an election for something every year.

You can destroy a hard drive however you want, and the key is to be safe. A drill or hammer will work fine. Government agencies like the CIA and NSA use specialized machines that cost thousands of dollars to wipe hard drives, and you can find software programs that will "shred" files for you if you plan on re-selling your computer, but data on an intact hard drive can almost always be recovered.

Bed sheets should be changed once every two weeks at the very least. If you sweat at night, you should change them more often. Washing a comforter is a hassle, so you should also use a top sheet so that if you do sweat at night, your top sheet gets dirty, not your comforter.

At 180 degrees, your ladder is lying flat on the ground. At 90 degrees it is lying flat against the wall. At about 70-80 degrees, it is leaning into the wall at the perfect angle. If it was at a 45-degree angle, for example, it would be at risk of sliding down the wall.

All you need to start a charcoal grill is fire and charcoal. Lighter fluid will make it easier, but you should never use a candle to start your grill. You can add wood chips for flavoring, but all charcoal grills are powered by charcoal.

If you pour used cooking oil down any drain, it can clog it because it solidifies. The best way to discard it is to wait until it cools, and then pour it into a resealable bottle or jar and throw it in the trash.

It is recommended that you floss before you brush your teeth. This allows for a deeper brush. It's also recommended that you brush and floss after every time you eat, but if you only choose to do one, you should choose to floss.

Bending a wire clothes hanger is probably the most effective way to unclog a drain. You can also buy a drain snake, and the key to whatever you use is its flexibility. Sink drains clog because stuff gets stuck in the pipe's twists and turns.

A social security number is just a number used to track social security benefits, but it is used as a form of identification in almost every situation. It is nine digits long and is one of the numbers every person in America memorizes.

The inventor of Levi's jeans has gone on record saying you never need to wash your jeans, and studies have shown that whether you wear them for two weeks or two years without washing them, they'll have the same amount of bacteria. Therefore, you should wash them when they get dirty. Over-washing jeans will ruin their look and feel.

Tylenol, Advil and Aspirin all offer pain relief, but it's a good idea to know they all contain different active ingredients. If you have a toothache and Aspirin isn't doing anything, it's because you need ibuprofen, which is the active ingredient in Advil. Mixing them is never a good idea.

It's going to take about an hour to bake a potato at 350 degrees in the oven, depending on its size. A sweet potato will need to be cooked for even longer or at a higher heat. You can poke the potato with a fork, and if it easily slides in, it's done.

If your car's tire wheels are sliding on snow, they've lost all traction, and if you jam the brakes, you will never regain traction. You will just continue sliding. To regain traction, turn your wheel and gently tap the gas. Once you feel your tires get a grip, you can steer to safety.

You should always tip at least 15% at American restaurants, and to find 15% of any number, find 10% and then 5% and add them together. So for this situation: 10% of 80 = 8 and 5% = 4. Eight plus four equals 12.

If you hang sweaters and t-shirts or any other light or stretchy fabric, it is at risk of stretching out of shape. Clothes hangers can indent shapes into some clothing, but not blazers. Blazers and suit jackets should never be folded, and if you must do so for travel reasons, you should learn how to do so properly.

All milk will spoil five to 10 days after the printed date once it's opened. Lactose-free milk will last longer than whole milk, and if the milk isn't refrigerated, it will spoil even faster. If your milk doesn't spoil after two weeks, it's not milk.

All U.S. salaried employees must file a W-2 so the IRS can track how much money they've been paid and how much taxes they've paid. The IRS tracks all sources of income, and whether you're an independent contractor or retired and living off dividends, you'll need to report income via the proper form.

You are not allowed to speed at all when driving. If you're doing 66 mph in a 65, you can get a speeding ticket, although it's unlikely. Most officers will let you get away with speeding as long as you only exceed by 10% of the speed limit. So you should be safe up to 72 mph in a 65 mph speed zone.

Although it is technically "safe" to put hot peppers in the microwave (i.e. the microwave shouldn't explode), you will get hit with a cloud of what is essentially pepper spray when you open the microwave door. Aluminum will cause sparks, and Styrofoam will melt.

You can jump-start a dead car by using another car or a portable jump starter. Either way, you'll have to use jumper cables. The red cable connects the positive terminals between the dead and live battery. Nothing gets attached to the negative terminal on the dead battery.

There's nothing like a steak sizzling on a skillet or fondue bubbling in a pot, but if you're going to set these items onto a dinner table, you need to use a trivet. Placing a skillet or boiling pot directly onto a dining table will likely damage it.

Science says 20 minutes is the perfect amount of time to recharge your body, but it takes a lot of practice to master the skill. The best way to power nap is to drink some caffeine and sleep for 20 minutes. The goal is to wake up when the caffeine is kicking in.
