Not ready to buy a new car? Here are 10 tips from the Kiplinger quiz that can help you keep the car you have now running smoothly and save you some money:
1. A dashboard light just went on. Something about oil. What should you do?
ANSWER: Pull over and turn off your engine as soon as safely possible. Let’s play this one safe. Sure, it’s possible that the light has something to do with oil level or an oil-change interval, but in case it’s the oil-pressure light, you need to act in minutes, if not seconds, to keep your engine from destruction. Now that you’re safely stopped, open up your owner’s manual and look up “oil” to see what you’re dealing with. If it is the oil pressure, you’ll likely need a tow.
2. Skip the automatic car wash if you give a darn about your paint?
FALSE: The automatic wash is a safe option — and it’s always a better choice than the teenagers raising money with a hose and dishwashing soap (just smile, give them $5 for the cause, and keep going). That said, there are differences among the automatics. Look for a “brushless” option — or better yet, a “touchless” option. If you want to be part of the action, bring your own clean, soft cloths to dry your car. They’re probably in better shape than the rags wielded by the attendants, which if contaminated by dirt or sand will have the effect of sandpaper. (That’s one of the main hazards of the teenagers, too.)
3. You can deny your car premium fuel.
TRUE: Few are the cars that really need premium gas, and their owner’s manuals will tell you if you do. What’s more, most of the cars that specify higher-octane fuel will run just fine on regular — though you might give up a smidge of power and economy. If your car is turbo- or supercharged and specifies super, follow the manual.
4. What’s the best coin to use to gauge whether there’s enough tread left on your tires?
ANSWER: Quarter- You may be familiar with the penny test: Stick a penny in a groove head-down, and part of Abe’s head should always be covered. The penny test proves that the tire has 2/32″ of tread, the legal minimum in most states. But at that level, your tire’s ability to cope with rain — not to mention snow — is dramatically reduced. If you’re going to be dealing with wet stuff, you need more tread. Use a quarter instead. If George’s pate has some coverage, that’s 4/32″, a safer margin. Here’s a picture of how to do the test.
5. You don’t drive a lot and your tires seem to wear like iron — over six years and there’s still plenty of tread. Lucky you — keep on truckin’.
FALSE: Sorry, those steel-belted ultramilers could be falling victim to aging, sometimes called dry rot. Tire rubber contains anti-aging chemicals that keep it flexible. Over time, these dry out from exposure to the elements — sun in particular. There’s no hard-and-fast rule on when a tire expires, but as a tire gets older, examine it carefully for small hairline cracks. In extreme cases, old tires can fail catastrophically with no warning. We wouldn’t ride on anything more than ten years old.
6. You love your car and want it to last forever. And it looks like it might rain tonight. It’s parked in front of the garage. Should you pull it in?
ANSWER: No, the water that’s a real danger to your car (unless you left the sunroof open) isn’t what falls from the sky; it’s the water that’s a byproduct of combustion. On a longer trip, your car’s engine gets hot and the water is boiled out of the oil and your motor — no worries there. But a 30-second trip from driveway to garage won’t do that, leaving you with water diluting your oil and rotting your car from the inside out. Avoid short trips when you can.
7. Your next oil change is due when?
ANSWER: Whenever your owner’s manual says.
Sure, Uncle Marvin changed his oil every 3,000 miles and his Studebaker ran forever. But oils have evolved, and so have engines. Stick to the manual’s recommendations and refuse all entreaties from service managers and ad campaigns. Note that your manual may tell you to follow your car’s electronic oil-use sensors rather than go by a specific mileage.
8. With the massive battery pack in that new hybrid, you can kiss your jumper cables goodbye?
FALSE: Hybrids have a conventional 12-volt lead-acid battery in addition to whatever exotic chemical composite battery takes care of the hybrid drive. If the kids leave the dome light on, you’ll need a boost to get your system going like everyone else. Prius owners, there is a 12-volt battery in there. You just can’t see it. Check your owner’s manual for jumping procedures.
9. You can take a car that’s under a new-car warranty to your trusty corner mechanic for regular maintenance.
TRUE: Independent shops are fighting back against dealer marketing efforts that play on consumer fears of voiding a warranty. If you have your services done regularly with quality parts — and keep your paperwork — federal law is on your side. Check out the Magnuson-Moss Warranty Act. If your dealer makes you happy, fine. Enjoy the loaner car. But it’s frequently the more expensive choice.
10. What is the best interval for rotating your tires?
ANSWER: When the wheels are off the car for other services. Tire rotation is one of the least critical of maintenance issues. If you don’t do it, your tires will wear our somewhat more quickly, true. But here’s a case where you can skimp. Don’t pay extra to have it done. If the car’s already in the air for an inspection or other service, ask your friendly mechanic to put the wheels back on in different spots. Note also that more and more tires are directional — which makes rotation less feasible. What’s a directional tire?
