Car Repair Tips and Tricks: When to Avoid Them
It seems like everyone is eager to share car repair tips and tricks when you’re experiencing trouble with your vehicle. The problem is, no matter how well-intentioned this help might be, occasionally some folksy wisdom passed down about automobiles can actually lead to more harm than good.
Check out this list of three car repair tips and tricks you may actually want to avoid.
1. Cutting Your Springs
Many people want to lower their car for better looks or improved handling, which is why there’s an entire aftermarket of parts suppliers that will outfit your ride with lowering springs that have been specifically designed for your vehicle. One of the more common car repair tips and tricks is recommending you simply cut a few coils off of your stock springs to achieve the same effect. Unfortunately, modern springs use a “progressive” spring rate, which means if you cut off a coil you could negatively impact safety and performance. It’s simply not worth the risk.
It’s tempting to see the two to three octane ratings at your local fuel pump as indicators of how much power they’ll help your engine make, but that’s not how octane works. The octane number you see listed beside regular, midgrade and premium fuel is simply an indication of how well the gasoline resists something called “knock,” which occurs when gas ignites inside a cylinder after being compressed, but before the spark plug fires.
The higher the number, the more resistant to knock it is, allowing it to safely be used in high compression engines or those that use turbochargers and superchargers. Unless your car is tuned specifically to take advantage of this knock resistance, using premium fuel is one of those car repair tips and tricks you can ignore, as it won’t give you better performance.
3. Removing Your Catalytic Converter
Once upon a time the emissions systems outfitted to automobiles were primitive to the point where they did more harm than good, choking away power in the interests of cleaning up the tailpipe. Modern vehicles are an entirely different story, but that hasn’t made this old school entry into the car repair tips and tricks lexicon go away. You’ll hear about the benefits of removing your car’s catalytic converter from any number of amateur performance enthusiasts, but the benefits simply aren’t there — and you could end up failing your next inspection.
There are a lot of car tips out there, but keep in mind not every one is a good for you and your car.
