4 Common Car Maintenance Mistakes
Proper Tire Inflation and Rotation :
Tires leak naturally and need the occasional check. Figuratively speaking, under-inflated tires suck up gasoline. Under- or overinflated tires wear out sooner, and deliver the same emergency maneuver handling as marshmallows. You probably aren't going to check tire pressures monthly, but how about twice a year?
Furthermore, front and rear tires wear differently and should be rotated to even that wear. Your owner's manual will have a recommendation on both pressure and rotation periods.
What other car maintenance mistakes should be added to this list?
Wiper Tales:
Here's a news flash: It's much easier to avoid hitting things you can see. Simple as it is, that's the concept behind replacing your windshield wipers before they fossilize into noisy uselessness.
Fall is the ideal wiper replacement time: after the blade-baking summer and before the fall and winter nastiness. Depending on location, wiper replacement may be an annual affair in the Southwest to a biannual chore in northern climes.
Tune-Up Anachronism:
There are no more "tune-ups." Valves no longer need adjusting, ignition timing is computer controlled and there are no carburetors to fiddle with. About all that's left of the old tune-up drill are the spark plugs. These are often good for 100,000 miles, so don't change parts just to change parts. Instead, save up for those big 60,000- and 120,000-mile services when the timing belt, spark plug wires and coolant are due for replacement.
Octane Overdose:
"If some is good, more is better" thinking does not apply to octane. Here the rule is to supply whatever octane the engine is rated for and call it done. Higher-than-required octane does not yield more power or mileage, only oil company profits.
Some engines are rated for premium 91 octane fuel but can burn 87 octane regular, thanks to the magic of knock sensors. In that case, run regular gas if puttering around surface streets, and premium fuel if full-throttle driving is part of your daily repertoire.
