Top 10 Mechanic Scams! Don’t get GOT!!!

We have a lot of respect for competent, honest, highly skilled auto technicians. Working on modern vehicles demands unprecedented talent and training. But then there are the shysters that perpetuate stereotypes. They know all the old mechanic scams and routinely sell premature or unnecessary parts and services. It’s bad enough they bleed you for extra money wherever they can, but they’re also screwing with your ride. Whether that’s by design or incompetence, you could face more repairs, a breakdown or even a wreck.

Be a Better Man, even if they aren’t, and be aware of these mechanic scams some may try to run past you.

No.10 Replacing spark plugs prematurely

In your father’s day, spark plugs had the lifespan of a housefly compared to their modern counterparts. Open your owner’s manual to see for yourself and you might discover that you drive a car with 100,000-mile spark plug replacement intervals. Even if that’s really only feasible under the most gentle of operating conditions, you see our point: Don’t get talked into premature replacement unless there’s a legitimate need to address a drivability issue. Then, ask to see the culprits. Plugs often have telltale visual signs when something’s amuck.

No.9 Engine treatment

This mechanic scam often comes up at oil-change joints, but it’s also at some repair shops and they’re on store shelves too. The pitch is that by adding just a little of the product to the oil, the engine will run like new. Between our own testing and the expertise of some techs, results are mixed. They may not necessarily harm your engine, but the benefits, if any, seem minimal and temporary at best. If the idea is to quiet noisy lifters, for example, you may have bigger issues not to be ignored.

No.8 Unnecessary upgrade to synthetic oil

Whatever your opinion on the last mechanic scam, you can’t discount the benefits of the original engine treatment: regular oil and filter changes. When done as recommended by your car’s manufacturer, you’ll probably avoid needing miracle cures altogether. Just don’t get scammed with an unneeded upgrade to synthetic oil. Although synthetic definitely won’t harm your engine, there’s no point in using it in the 200,000-mile car you’re going to replace soon either. Finally, while most of us will benefit from using the more expensive stuff, don’t let them gouge you on the cost.

No.7 Replacing air and/or cabin filter prematurely

Here’s another scam seen frequently at the McOil Change places. The mechanic has grim news to report: It’s your air filter, and it doesn’t look good. Maybe the cabin filter too, and that’s important to maintain healthy air inside the car. Right. A guy looking like Kid Rock with missing teeth and cigarette breath is lecturing about health. Anyway, the good news is he can replace both right away. Ask to see them first. If you can’t see daylight through them or they’re obviously dirty, only then do you consider proceeding.

No.6 Transmission treatment

Tranny servicing isn’t just a section on Craigslist, it’s something you’ll need to explore on your car. It’s also a source of mechanic scams. For too many people, too little attention is paid to the transmission. Beyond when to put it in park, reverse or drive, no conscious thought is given until there’s a malfunction. So, avoid pour-in services claiming to calm fears and extend service life, as they’re not a lot different from the engine treatments we addressed earlier. For most drivers, sticking to fluid and filter changes at recommended intervals is the best practice.

No.5 Premature cooling-system flush

The idea of a cooling-system flush itself isn’t truly a mechanic scam, but selling it prematurely is in many cases. Let’s say your coolant tests in the acceptable performance range, but you’re at the manufacturer’s recommended change interval. While you could just have the drain and refill done, a little extra time and money can buy a full cooling-system flush. Why not splurge on this car colonic? Unless the manufacturer recommends it or the existing coolant is seriously ineffective or contaminated, it’s just flushing money away.

No.4 Unneeded air conditioning recharge

You might think you know whether or not your air conditioning is fully functional, but the mechanic disagrees. “You’re only blowing X degrees,” he says, which stirs potentially unsettling mental images. Then he offers to recharge the system’s refrigerant, which is something most of us won’t touch on our own. So where’s the scam? If you’re not noticing any defects or diminished cooling ability, you’re probably just being asked to address an inconvenience before it ever happens. Again, not a car-killer, but it’s an issue of spending too much too soon.

No.3 Premature shock/strut replacement

Sooner or later, you’ll need to replace your car’s shocks or struts. The mechanic scam here is when “sooner” is pushed too hard. Do a little pushing of your own. The old bounce test on your bumper in many cases is still a reliable way to tell if your shocks or struts are really bad, but also pay close attention while driving. If the car is like a bobblehead doll after hitting bumps, pitches and rolls in slow corners or is noticeably unable to quietly absorb all but the slightest imperfections, then it’s time.

No.2 Fuel injection service

Here’s a mechanic scam with ties to the engine and transmission treatments mentioned elsewhere. Again, it’s all about removing contaminants and restoring efficiency and performance, like finding “hidden” horsepower. And like the others, it’s to be taken with a massive grain of salt — probably best avoided altogether. Name-brand gasoline usually contains enough additives to keep typical engines free of serious buildup under normal conditions. If you do want periodic help, skip the expensive service and add a bottle of name-brand treatment to your tank, such as Techron.

No.1 Premature brake pads/rotors

The mechanic’s not lying: You do need fully functional brakes, and the pads and rotors aren’t at their peak thickness levels. But think about it. Technically, “peak thickness” only exists upon installation; everything after that is compromised. So, don’t ignore your brake system by any means, but also be aware of what does and doesn’t happen when you use them. If there’s truly a legitimate issue, address it. If not, don’t get taken by this mechanic scam and spend money prematurely.
