Game the Gas System
If you are going to fill up at a station and you see fuel tankers there refueling the pumps, try a different station. In fact, you will want to avoid that gas station for a day or two. Why? As those underground reserves are being filled, there is a slew of sediment and debris being stirred up by the new turbulence. Since that grime can clog up your fuel filters and injectors, you are better off avoiding it all together. Clogs can translate to nasty repairs down the line and severely impact performance.
Keep the Keychain Light
No matter how cute you find keychain collections or how convenient it is to store all your keys on your car keyring – don’t do it. All that weight is bad news for your ignition. As that heavy load bounces around while driving, it can wear out the tumblers inside the ignition, which inevitably leads to ignition switch failure. You should invest in a light keychain that you can easily detach your car key from and drive with only that key in the slot. If you find your key sticking when trying to turn on the ignition, that is a warning sign that the switch is about to fail.
