5 Biggest Car Maintenance Mistakes That Cost Drivers More
Most car damage does not begin with one huge mistake. It usually starts with small, everyday, poor maintenance choices that drivers think are completely harmless.
In Pakistan, where fuel prices keep climbing and every extra rupee on the road matters, many of us make small car-care choices that feel smart in the moment. “Yeh bhi chal jayega,” we tell ourselves, and opting for the cheaper oil, skipping a service because the car still starts fine, or following the mechanic bhai’s quick advice.
These everyday shortcuts seem harmless, but they quietly steal fuel efficiency, make the car run rougher, wear parts faster, and turn into much bigger bills later.
Let’s bust some of the most common car maintenance myths that are secretly costing you money.
Myth 1: Any engine oil will do as long as it’s cheaper
Oil is oil, right? When it’s time for an oil change, many drivers just ask for the cheapest oil available or trust the mechanic when they say, “yeh bhi chal jaye ga”.
But the reality is different…
Choosing engine oil is not just about picking a brand or a color. Car manufacturers engineer their engines to run on specific oil specifications and viscosities.
Using an incorrect engine oil causes:
- Poor lubrication
- Increased friction
- Long-term malfunctions or damage.
Instead of just blindly buying and settling for any cheap oil, you must:
- Always follow your vehicle owner’s manual
- Use the exact recommended grade and viscosity for your car, such as 5W-30 or 0W-20
It may cost a little more now, but it protects your engine, improves fuel economy, and helps you avoid expensive repairs later.
Myth 2: If the car feels fine, you can delay maintenance
Our awam thinks taking a perfectly fine car to the workshop is unnecessary unless it starts showing signs of trouble. We often think, “The car is running okay, so I’ll delay it,” or “The mechanic said it’s fine for another few months.”
But here’s the catch….
Vehicles degrade gradually. By the time you notice an obvious symptom like a grinding noise, dark smoke, or severe shaking, the problem has likely already become an expensive repair.
According to AAA’s automotive research, skipping regular maintenance significantly increases the likelihood of catastrophic and costly failures.
So what you are supposed to do is:
- Don’t wait for a failure.
- Stick to the scheduled checks and follow your manufacturer’s service intervals.
Regular maintenance is specifically designed to prevent these serious damages from occurring.
Myth 3: You should warm up your car for several minutes before driving
Especially during winter, many drivers let their cars idle in the driveway for five to ten minutes, believing a long, stationary warm-up is better for the engine’s health.
This looks like a sensible practice until you hear it isn’t….
While this was true for older carbureted engines, modern fuel-injected vehicles do not need to be warmed up for long before driving.
According to the U.S. Department of Energy, prolonged idling wastes fuel and can strip oil from the engine’s cylinders and pistons, contributing to long-term engine wear.
Do the following instead:
For most modern cars, a brief startup (just a few seconds for the oil to circulate) followed by gentle driving is the best approach.
Driving the car is the fastest and safest way to bring the engine up to its proper operating temperature. Your engine (and your pocket) will thank you, especially with today’s fuel prices.
Myth 4: Tire pressure only matters when a tire looks flat
It is a common observation that pulling out a pressure gauge feels like a hassle, so the logic becomes: “I only check tires when one looks low.” We only check tires when one visibly looks low or after a puncture. Visual inspection feels enough, and who has time to check PSI every month?
But checking your tires monthly is a must because….
- A tire can lose a significant amount of air pressure before it physically looks flat to the naked eye.
- Underinflated tires increase crash risk, reduce tire durability, and force your engine to work harder, which directly hurts your fuel economy.
The National Highway Traffic Safety Administration (NHTSA) explicitly warns that proper tire pressure is one of the most crucial parts of car maintenance.
So, stop relying on visual guesswork and,
Check your tire pressure regularly with a proper gauge and inflate them to the recommended PSI number on your car’s door sticker or owner’s manual, not by eye.
Myth 5: Premium fuel is always better for your car
Because High-Octane fuel is more expensive, the natural assumption is that “premium fuel must be better because it costs more.” Many drivers believe it automatically cleans the engine and boosts performance even for the cars that don’t need High-Octane.
But….
Extensive research by AAA has shown that if your vehicle was designed to run on regular gasoline, there is absolutely no benefit to using premium fuel.
- It will not improve your fuel economy
- There will be no increase in your horsepower
- It will not extend your engine’s life. You are simply spending extra money at the pump for no added value.
What your suppose to do is,
Read your owner’s manual. If your car specifically requires or recommends premium fuel, use it. If it calls for regular, save your money and stick to regular fuel.
