Regular maintenance is an essential part of vehicle ownership, especially if one wants to preserve the vehicle’s longevity, mileage, and performance. However, various common myths and outdated car maintenance practices continue to linger, often resulting in vehicle damage and unnecessary expenses. Understanding the truth behind these myths can help one make informed decisions about their car’s maintenance and ensure they have a smooth, safe driving experience for years to come.
1. Warming up the engine is crucial before driving in cold climates
People often think that their vehicle needs a lengthy warm-up before they start driving. While this may have been true for older cars, it is no longer the case today. Idling with the engine on for too long wastes fuel and increases emissions. It also exposes the car to more cold-start wear and tear than it would while driving. Instead of trying to get the engine going for a while, one should only give their car 30 seconds to a minute before driving, and then take it easy on the gas pedal for the first 15 minutes at least. One can always check the vehicle manual for the manufacturer’s recommendations on cold-start driving.
2. Premium fuel enhances performance in every vehicle
High-octane fuel may seem like the key to boosting performance, after all, that is exactly what the big racing leagues believe. However, regular car owners must avoid falling for this notion, as premium fuel does not always improve the vehicle’s performance. High-end sports and racing cars use premium fuel because they have been configured in a way that can get the most out of this type of fuel. For regular cars, though, it is generally better (and more cost-effective) to opt for mid-regular 87-octane (or unleaded) gas. That said, always check the owner’s manual for fuel recommendations before filling up the tank.
3. Oil should be changed every 3,000 miles
This is another old practice that has maintained its stronghold on vehicle owners. Most modern cars do not need to have their oil changed every 3,000 miles, as there have been significant advancements in engine technology and oil quality, resulting in less degradation. As a result, vehicles can comfortably go up to 10,000 miles without needing an oil change. That said, to ensure one adopts safe practices, one can always rely on the owner’s manual for specifications regarding oil type, viscosity, and the recommended oil change intervals.
4. All the tires must be replaced at the same time
This myth can cost car owners a pretty penny! Replacing all the tires at the same time arises out of the misconception that all tires likely have the same wear and tear. In reality, this decision is quite complicated. To determine if complete replacement is necessary, it is advisable to have the tires inspected by a trusted professional, as the answer will vary for every car. This difference is especially stark between 4WD and 2WD. For an all-wheel drive, replacing only one tire can damage the drivetrain, especially if the tires have more tread wear than the manufacturer’s recommendations.
With front- or rear-wheel drive, one can replace individual tires if they match the other tires in size and type.
This decision is also contingent on the type of wear the tires have undergone. For instance, adding a new tire to a set of three unevenly worn tires may cause faster wear-and-tear in all four tires, giving rise to transmission and stability problems. That is why seeking professional advice is the safest way to proceed in these circumstances.
5. Car battery lasts for five years
Generally, the car battery lasts for about three to five years. That said, one’s driving style and the local climate are the key factors that influence its longevity. To avoid running into any issues while driving, one should get the system tested when it approaches the three-year mark.
6. All services for a car under warranty must be performed at the dealer
There’s no need to go to the dealership each time one needs to get their vehicle serviced. Regular maintenance and repairs can be done at any facility of the owner’s choice as long as it is properly documented. These documents must be maintained properly for the car’s warranty to remain valid.
7. There’s no need to fix what isn’t broken
A common misconception is that if the car seems to be fine, there is no need to carry out regular maintenance. This can be rather dangerous. Ignoring maintenance, such as oil changes, tire rotations, etc., can lead to unexpected leaks, breakdowns, and engine damage. This would mean high repair costs. To avoid these issues, one must take the car to a licensed professional for a routine inspection.
8. Tire pressure must reach the number on the car sidewall
Inflating tires to the maximum pressure stated on the sidewall is a common car maintenance myth to ignore, as it will result in an uncomfortable ride, increased tire wear, and reduced traction. Instead of relying on the number on the sidewall, one must look for the recommended tire pressure, which can be typically found on the fuel-filler door, glove box, or driver-side doorjamb. Sticking to the recommended pressure can help one ensure they have a smooth, safe, and fuel-efficient ride.
