Every one of the five ridiculous maintenance sales rules I wrote about above is programmable. That means you can either adjust the rule or get rid of it.
The first rule that must be programmed Maintenance is automatic keypads. Again, that rule has to be changed every few years because software updates prevent its activation. As software keeps changing, the keys on your keyboard must change as well.
Rule number two is oil filters for cars and truck exhaust systems. They’re programmed into your car’s diagnostic system and are determined by the year, make, and model of your car. In other words, all of the filters are programmed the same way. But that doesn’t mean you have to buy a new set of filters every year.
Rule number three of the five ridiculous maintenance sales rules are the adjustable windshield wiper blades. You can buy an air compressor to increase the effectiveness of the wiper motors on the dash of your car.
Rule number four of the five maintenance sales rules are always unplugging your vehicle when changing a tire. How do you know when it’s safe to unplug? Most tire-changing accidents are caused by a car that didn’t take the time to disengage the starter.
Rule number five of the five maintenance sales rules are always changing the oil and filter on your car. Your oil-change tool kit is programmed with this rule in mind, so you can easily change the oil on a consistent basis.
Rule number six of the five ridiculous maintenance sales rules are changing your tire pressure on a regular basis. The flow-meter that comes with your car may be programmed with a different rule. It’s not a rule; it’s an instruction. Rule number seven of the five maintenance sales rules are changing your oil when the oil gauge reads less than eight pounds. You’ll notice that this rule is in effect in your car even if you start to feel the oil becoming dirty, even if you have problems with your car’s engine.
Rule number eight of the five maintenance sales rules are changing your oil more often than once every six months. This rule applies to all vehicles that have computerized oil-change programs and it also applies to cars that use sensors to check their oil levels.
Rule number nine of the five maintenance sales rules are changing your oil from one brand to another brand. You’ll notice that the rule doesn’t apply to your automobile, however, so don’t expect your dealer to tell you this rule.
Rule number ten is changing your oil on a cold day when the outside temperature is well below zero degrees. The rule works only in your automobile if you buy it with a software program. If you install a homemade program on your own, you’ll be disappointed.
Rule number eleven of the five maintenance sales rules are changing your oil when your car breaks down because you don’t know how to use a screwdriver to change a drain plug. This rule is programmed into your automobile if you buy a car with a computerized oil-change program. If you want to know how to change a drain plug, contact your auto-parts retailer for help.
