18 Ridiculous Car Maintenance Myths

last updated March 11, 2019

There’re many myths surrounding car maintenance. They’ve been in existence for as long as car ownership has been mainstreamed. Car owners have heard lots of them and they’ve been a common practice worldwide.

Car Maintenance Myths

Listed are some of the car maintenance myths that have been passed along over the decades.

Ridiculous car myths

1. Premium fuel is better than ordinary fuel

This myth has been passed along for decades. Fortunately, this is just a myth and most cars will work well using ordinary fuel. Premium fuel is better for high compression engines. Other cars run properly on ordinary fuel and their engines last a long time without the need for engine replacements.

In addition, premium is a bit costly compared to ordinary gas. Fuel is a regular expense and for most people, it is important to cost-cut recurrent expenses. This is another advantage of using ordinary fuel for your car.

2. Let your engine warm up before you start driving

The best way to warm your engine is to get the car moving rather than wasting fuel by having it run while stationery. This is bad advice to follow especially for those who live in cold areas.

Letting your engine run while the car is idle only serves to warm up the inside of the car and does not help to improve on the performance of the car. Also, remember not to rev your car in the first minutes of driving.

3. Change your engine oil after every 3,000 miles of travel

This advice is not for all car owners. Ordinary city drivers do not need to change their engine oil after 3,000 miles, they can get double the mileage before they need an oil change.

Car experts are of the opinion that modern synthetic engine oils can afford your car up to 10,000 miles before it ever requires a change of oil. For the driver who’s not using synthetic engine oil, their car can easily cover 7,000 miles before it needs its a fresh change.

This advice was offered by car service experts who figured that at 3,000 miles, their customers would come back to their shops regularly enough to keep them in business.

For the best time to change your engine oil, consult your car owner’s manual and follow the instructions or recommendations offered therein.

4. Replace all your tires at the same time

The main motive behind this myth is to keep the tyre industry in business. It’s often wrong information gained from reading on the losses suffered by others. It’s possible for a single tire in the car to need changing before the rest.  If this is the case, then don’t be afraid to change that one car tire.

To counter this myth, change the positioning of your tires on the car regularly. At least every quarter. This will help ensure that none of the tires is carrying too much weight on its own. If a puncture occurs, you don’t have to discard the tire and buy another. It is much easier and cheaper to have the tire repaired rather than having to buy another tire.

5. Using the air conditioner is harmful to your fuel economy

Really!

The air conditioning and the fuel efficiency of your vehicle have nothing in common when it comes to the car’s functionality and effectiveness. While using the air conditioning could eat up a large portion of your battery power, it is quite difficult for it to interfere with your fuel efficiency.

Rather than using your AC, it’s better and easier to roll down the windows to get air into the car as you drive.

6. Using jet fuel will enhance speed in your car

Do not use jet fuel in an attempt to boost the speed of your car. Jet fuel is not compatible with car engines. Why? because jet fuel is resembles paraffin. Car engines don’t have the ability to burn jet fuel.

Putting jet fuel in your vehicle’s engine causes irreversible damage. Once your engine stalls due to using the wrong fuel, it might be difficult to repair and you will end up having to buy another car.

7. You can wash your car with dishwashing soap

This is another myth that has been in existence for a while now that I believe has been discarded. It is advisable to stick to car wash soaps rather than dirty soaps which are built to remove grease.

Dishwashing shops are designed to wash off grease.

This is likely to eliminate the luster of your car’s shine and leave it to have a bland and boring exterior.

Also, washing your car using detergents. They also have the same effect as the dishwashing soap. Professionals recommend sticking to car wash soaps as they are professionally formulated for that purpose. They will keep your car looking good, new and well maintained.

8. Once you jump start your car, you do not need a new battery

This is a myth that should have come to an end by now. Car maintenance professionals advice that you get your battery checked on the very first instance that you need a jump start. A jump start is an indication that your car battery’s voltage is low and therefore your car needs a new battery.

Also, your battery could have a loose connection and it is important to remember to have it checked. If you need a jumpstart for your car every time you stop, a new battery saves you the embarrassment and is the best option.

9. Powerful engines are more powerful than their brakes.

This is another myth that doesn’t make sense. It’s ridiculous since a car needs to stop when it arrives at its final destination. If there was any truth on this myth, how then would cars stop?

All brakes function to stop the car, even for the car with the most powerful engine, brakes are an indication to slow down on the road and to come to a complete stop.

Whether the car has a powerful engine or an ordinary one, stepping on the brakes will slow it down and eventually stop it.

10.  Manual transmission cars are better than automatic transmission cars

Some time back this statement would have been considered true. Now technology has ensured that whether a car has an automatic or manual transmission, they have the same technology. The cars, therefore, have similar transmissions and everything else on the road will be determined by how experienced the driver is.

11. Tires are better when inflated to the psi indicator on the tires

The PSI on the wheels indicates the maximum pressure that your tires can inflate to. Maximum inflation levels don’t mean the ideal inflation levels. This is often indicated elsewhere and not on the tires.

Properly inflated tires ensure that the car is safe and enhances proper handling for the vehicle. You should ensure that you consult professional on where to look and for a recommendation on the ideal levels of inflation for your car tires.

12.  Electric cars are likely to catch fire

As electric cars increase on our roads and neighborhood, we understand how they work and we can now see that this statement is a myth. Professionals have indicated that cars can catch fire whether they are electric or gasoline driven.

Electricity and gasoline are both fuels and can exacerbate fire. Once a fire starts, in any of these two cars, you should be far away from them or working hard to combat the spread of the fire.

13.  Refueling in the morning gets you more fuel in the car

Why do most people believe this? Because heat causes gasoline molecules to expand while lower temperatures makes it contract. When you fuel on a sunny afternoon, you won’t get as much fuel as you would have had you fueled in the morning or evening.

Unfortunately, that’s a lie. Why? Because gas companies already know how to go around this problem. Fuel is stored in underground tanks. This ensures that it’s not affected by the weather in any way that may lead to its expansion or contraction at different times of the day.

14.  Change your coolant when you get an oil change

This is another myth that’s been passed around on many drivers although it is not really practiced. Car maintenance professionals feel that coolants and car filters can only be changed after  50,000 miles have been logged. It’s important to have regular checks and top-ups of the coolant to ensure that it maintains its optimum levels before the 50,000-mile limit is reached.

15.  You will void your warranty if you don’t service your car at the dealership

Most people prefer to have their car serviced by someone they know. When the time to service the car comes, rather than go back to the dealership, they will take their car to their favorite service shop.

According to the manufacturer, the most important activity here is that the service occurs on time as recommended in the user’s manual. It’s also important that the service completed is documented and receipts collected that can be used as evidence if ever they were a dispute over the warranty of the vehicle.

16.  Your car is okay if there are no noises or visible damage

It is not true that just because you cannot see or hear noises indicating damage to your vehicle that it is okay.

Regular service and maintenance of your vehicle is important and useful. Regular maintenance keeps the car in proper working conditions and ensures that it is useful for longer. Ignoring the need to service your car leads to problems that could have been easily detected during service and may lead to expensive repair costs.

Service your car as often as recommended by the manufacturer and ignore this false myth.

17.  Tune up your car every six months

This is another self-serving myth perpetuated by mechanics. Unless your car really needs it. you do not have to take for a tune-up every six months. It is a waste of money and good car parts.

Find out what the car manufacturer says about tune-ups and go by their recommendations. General recommendations suggest that you can tune up your car after 50,000 miles for a new car or 30,000 miles for an old car. In addition, regularly serviced and maintained cars may not even require tune-ups.

18.  Prepare your car for winter

The suggestion brought forward by this myth is currently outdated. Modern technology allows cars to be fully loaded to handle any vagaries the weather throws at them. Car parts and oils that help run the cars are made with weather conditions in mind. This takes away the stress of needing to prepare for weather changes especially winter from car owners.

If you have the proper tires for winter, that is all the work you need. The manufacturer has taken care of everything else that may be recommended to make your car winter ready.
