Car Maintenance You Don’t Need–Including Most Every Kind of “Flush”

Even the smartest people sometimes feel foolish when speaking with car mechanics. We often say yes to maintenance services because we figure that the auto mechanic knows what is best for our cars. However, car owners sometimes overspend ­because less-than-honest auto repair shops talk them into services that their cars don’t really need. They also may not understand that today’s vehicles have different needs than those of decades past.
Among the most common money-wasting mistakes car owners make…
FLUID FLUSHES
Some quick-lube shops, independent mechanics and car dealerships pressure car owners into replacing automotive fluids that still are perfectly fine. In some cases, this will mean draining the fluids… in others, they might recommend actually flushing the system out completely, cleaning out virtually every drop of the old fluid. In either case, these services can cost $70 to $150 or more apiece.
Brake fluid flushes. Don’t trust a shop that recommends you flush your brake fluid regularly. Brake fluid can last as long as your vehicle. There are exceptions, however. Your brake fluid might legitimately need to be flushed if moisture gets into the system or the brake fluid has overheated.
What to do: Visually inspect your brake fluid once or twice a year, or ask a mechanic you trust to do so when you stop by for some other service. Brake fluid should be clear or translucent. If the fluid is rust-colored, moisture might have gotten in and a flush might be warranted. If your brake fluid is black or has a burnt smell, your braking system likely has a problem that requires a mechanic’s attention, not just a flush. If it is below the recommended level, it might have a leak.
If the brake fluid is clear or translucent, does not smell burnt and is at the correct level, agree to a flush only if your vehicle’s maintenance schedule calls for it, which is rare.
Power steering fluid flushes. Power steering fluid can last the life of a vehicle, too, unless otherwise noted in the vehicle’s maintenance schedule.
What to do: Inspect the fluid once or twice a year, or ask a trusted mechanic to do so for you. It should be flushed and replaced if it smells burnt or you see black grime or metal flakes in the fluid — shining a light into the reservoir can help you spot these flakes. There could be an underlying problem that requires a mechanic’s attention as well. Otherwise there’s no need for the flush.
Transmission fluid flushes. Automatic transmission fluid should be flushed occasionally — but some disreputable quick-lube shops recommend these flushes to seemingly every customer who comes in for an oil change. Most of those flushes are completely unnecessary and in some cases, might even hurt the transmission.
What to do: Have your transmission fluid flushed every 35,000 miles or so. Make sure that the shop replaces the filter when it changes the fluid. Some automakers say a transmission fluid flush isn’t necessary until perhaps 100,000 miles, but transmission fluid is an oil and oil can break down over time, so this is one situation where it makes sense to err on the side of caution.
Engine oil flushes. Ask some quick-lube shops and mechanics for a $25 oil change, and they will try to sell you a $100 to $200 engine oil flush. They’ll claim this is the only way to clear years of sludge out of the engine. Trouble is, any sludge that an oil flush does dislodge could clog the oil pump pickup screen, causing more problems than it solves.
What to do: Have your oil changed, not flushed. Get oil changes according to your vehicle’s maintenance schedule.
BUT DON’T CUT CORNERS
Sometimes not spending enough on vehicle maintenance ends up costing car owners. Examples…
Buying generic brake pads or delaying brake pad replacement. Low-­quality brake pads will wear out faster than higher-quality pads. That means you’ll have to return to the shop sooner to replace them, more than offsetting any money saved by buying the cheaper part.
Delaying brake pad replacement or using low-quality brake pads also can increase the wear on the brake rotors. That could force you to replace both the pads and rotors, which could easily double or triple the cost of the brake job. Using worn-out or low-quality brake pads also could reduce your ability to bring your vehicle to a stop in an emergency.
What to do: Replace your brake pads as soon as they have worn down to less than one-quarter inch in depth. It might be time to replace the pads if your brakes consistently screech, too — perfectly good brake pads might screech on wet days, but if the brake pads are still good, that screeching likely will not persist throughout a long trip or once the weather dries up. Opt for high-quality brake pads, such as those made by Wagner or Bendix. These typically cost $15 to $20 more per pad than the generics, but that’s a small price to pay for longer pad life, longer rotor life and greater safety. The original-equipment brake pads sold by dealerships likely are fine, too, but might be expensive.
Not replacing the air filter regularly. There’s no good excuse for not replacing your vehicle’s air filter ­every 10,000 to 12,000 miles. Air filters are inexpensive — usually $15 to $20 — and putting in a new one is a simple do-it-yourself job in most vehicles. If you don’t want to do this yourself, a mechanic should be able to do this for you for the cost of the filter and a half-hour’s labor or less. Continue to use a dirty air filter, and you cost yourself money by reducing your car’s fuel efficiency.
