Three products your car doesn’t need
Just as there are cosmetics that are useless, there are car products that are useless, too. While none of these are big-ticket items, those nickels and dimes add up.
- Oil additives. Your engine needs the correct oil, changed regularly. Oil additives not only don’t work, but can be harmful.
- Gas-savers. The EPA has tested them all, and they don’t work. Some can even lower engine performance.
- Nitrogen fill of tires. Don’t do it, unless you just enjoy burning cash.
Four services your car doesn’t need
- Engine flush. What your engine does need are regular oil changes.
- Fuel-injection cleaning. This unnecessary service could set you back as much as $200.
- Transmission flush. Flushing the transmission can stir up sediment that can then travel into small passages, such as precision valves, and affect the shifting quality of the transmission. If anything, R&R would recommend an alternate procedure, a drain and refill, which minimizes the chances of agitating sediment. You don’t really need a drain and refill, either, but if you decide you like the idea, do it regularly or not at all to minimize the chances of transmission damage. We recently encountered a customer whose transmission was destroyed in the aftermath of a dealer-advised transmission flush.
- Power steering flush. In our experience, this is unnecessary unless a failed steering component is being replaced.
