Last year we discussed a few ways to avoid the mechanic by completing your own simple auto maintenence. Today, MSN in Seattle adds 20 ways to waste money on your car.Can you add to to this list. To me it’s pretty good.Premium gas instead of regular. Buy the cheapest Fuel that doesn’t make your car engine knock. All octane does is prevent knock; a grade higher than the maker of your car recommends is not a “treat.”3,000-mile oil changesTaking false economies. Better to replace a timing belt on the manufacturer’s schedule than to have it break somewhere in western NebraskaUsing the dealer’s maintenance schedule instead of the factory’sUsing a dealer for major services. Independent shops almost always will do the same work much cheaperUsing a dealer for oil changesNot replacing your air filter and wiper blades yourselfGoing to any old repair shopChanging your antifreeze every winterReplacing tires when you should be replacing shocksLetting a brake squeal turn into a brake jobNot complaining when your warranty claim is rejected Not keeping recordsBuying an extended warrantyOverinsuring. Never skimp on liability, but why buy collision and comprehensive insurance on a junker you can probably afford to replace?Assuming the problem is majorNot changing the fuel filterNot knowing how to change a tire. Have you even looked at your spare?Not keeping your tires properly inflatedCar washesI personally agree with all of these. If you don’t let us know. For some reason auto maintenance myths always bring out the aggression in people. News source: dumblittleman
