8. Don’t Overinflate Your Tires
If someone tells you that you can get better gas mileage by overinflating your tires, don’t believe it. What will happen is that you’ll wear out your tires prematurely, increase your stopping distances, and wear out your suspension components. Not only that, but you’ll also have a rougher ride in your car. Instead of listening to your bonehead friends, check the placard inside the driver door’s frame for the recommended tire pressure for your vehicle. With that said, always make sure you check your tires’ air levels.
7. Don’t Rev the Engine
You should never rev your car’s engine in the winter to warm it up. It doesn’t work. Plus, it can damage your car because the oil hasn’t had a chance to work its way through the engine.
Revving your engine while sitting at a traffic light is a bad idea, too–well, revving it in neutral then shifting it into drive so you can do a “jack rabbit” start is. It can harm your engine–especially if it’s a brand new car–and wear down your transmission bands and piston rings, plus it could lead to additional problems down the road.
6. Don’t Drive When the Oil Light is On
An “on” oil light can mean a number of things. For example, it could be that your oil is really low or totally depleted. Or, it could also be that there’s a clog in the oil passage or that your oil pump is failing or has already failed. Instead of ignoring the light, pull over onto the shoulder and turn off your car. Then, get out and check the dipstick to see how much oil you’ve got. If it’s low on oil, you’ll need to refill right away–or at least before restarting your car. If not, you’ll end up destroying your engine. Even if there’s plenty of oil in it, you still shouldn’t drive it. Call a tow truck instead and then let a mechanic look at it to find out what’s causing the light to come on.
-Never use the wrong oil. It can result in a trouble code and cause the “check engine” light to come on.
-Never change the oil too frequently. Go 5,000 miles between oil changes under normal conditions. Go 3,000 miles between oil changes when you’re driving under severe conditions.
