In this article, Naijauto.com has compiled a list of 8 common car facts that are actually not true. To be honest, we don’t know why those things have been regarding as “facts” for years in auto world. Some might be true several years ago but for now, they’re already passé. Others, in the meantime, are subreptions. Let’s find out.

Car fact #1. Premium fuel is better for your car.

Premium fuel is not of the essence with regular cars
It is necessary to clarify that premium fuel is not of the essence with regular cars. It’s not cleaner or purer, but rather less combustible. In fact, a less combustible fuel is for high-performance vehicles to prevent the engine from knocking. If you fill your performance car with regular gas, you accidentally do serious harm to the engine and cut power, but if your car is a regular one, premium fuel is no better than the one recommended by the owner's manual.

Car fact #2. Changing oil every 3,000 miles is essential.
This adage is absolutely outdated. Nowadays, most vehicles can go as far as 7,500 – 10,000 miles without an oil change. Mind you, it’s better to follow the carmaker’s recommendation to keep your car in pristine condition.

Car fact #3. You should not use engine oil that’s turned black

Your engine oil turning black is just a sign of the oil’s operation
Presently, detergent-dispersant additives are added to engine oils to remove carbon deposits then keeping engine internal parts clean as well as maintaining them in innocuous suspension in the fluid. Thus, your engine oil turning black is just a sign of the oil’s operation. In truth, having carbon deposits in the oil to be drained off is better than depositing them in the engine.

Car fact #4. Hiding behind a vehicle will save you from gunfire.
Do not be completely convinced of Hollywood films. Despite the fact that some bullets is sometimes not powerful enough to cut through steel in old vehicles, we’re unsure what will happen to newer ones. The engine block area is actually a protective cover, yet it’s still a hit and miss. So, be cautious!

Car fact #5. Bullets can make your fuel tank explode.
Hollywood and Nollywood films once again show us that a bullet hitting the car’s gas tank might set off an almighty explosion.
However, it’s is something of an overstatement. There is no ignition in the tank, so how can it explode?

Car fact #6. Using A/C is better for fuel economy than letting the windows down.
It is horribly wrong. By contrast, a study carried out by GM and SAE figures out that turning the A/C consumes more fuel than leaving the window open. That said, opening the windows may cause the aerodynamic drag and the engine has to work harder. All things considered, it’s advisable to use the A/C while driving in order to keep yourself alert and more comfy.

Opening the windows may cause the aerodynamic drag since the engine has to work harder

Car fact #7. Warming up your car for several minutes before driving is required.

Currently, it just takes around 30 seconds to warm up your car
Warming up the engine is essential to make the heat turn on sooner, reduce emissions and cut down your fuel costs as well. Nevertheless, spending up to several minutes on this job is only needful if you own a car with a carburetor, but it has disappeared since the introduction of electronic fuel injection in 1980s. Currently, it takes just around 30 seconds to warm up your car.

Car fact #8. Old cars are safer than new cars

Key safety features like seat belts and airbags are fully set up in new models
Car fact #4 somewhat tells you that old cars are more protective than new ones. That’s right as their steel frames are more solid to resist impacts than modern vehicles’ economy boxes. However, at the present, cars have been engineered with “crumple zones” that better handle impacts. Beyond that, key safety features like seat belts and airbags, which are absent from classic machines, are fully set up in new models.

Lizilicious:
Let me go and tell that my neighbor to stop warming up his car for 3hrs in the morning and disturbing my early morning sleep

Just tell in a way that will nt make you look like enemy of progress

darlenese:



no. Fact are proven proven truth

Anyway, I edited the post.

These are myths

Nope. Facts are either true or untrue, so the topic sentence is logically correct. But you do have a point - for the purpose of common usage, "myth" works better in contexts like this. And it would be tautological to say: "Top 8 Common Car Myths That Are Actually Not True"

U are wrong, facts are verified assertions, they are always true.

Yohh:

U are wrong, facts are verified assertions, they are always true.

No. In some contexts, facts can mean things accepted to have happened. Facts are assertions that things happened. They are then either proved or disproved. That is why during a court trial they are separated into "accepted facts" and "disputed facts".

Car facts that are not true? .how can a fact not be true... Someone school me

With all these facts olden days car are still the best

I still don't believe that bullet to the tank won't make the car explode, isn't that like striking a match stick to petrol

Facts: Statements proven to be TRUE

Silensa:

So leaving the windows closed actually doesn't save fuel?
Thanks op

Keeping the window closed save fuel due to aerodynamics drag prevention, especially when driving with high speed on the highway,

Actually, when you are running at 60mph or above, it's more economical to roll up your windows and turn on the AC. It doesn't directly save fuel but just replaces the drag you get when the windows are open plus gives you comfort. As in a direct alternative. But when your speed is lower than 60mph and you are interested in saving your fuel, simply roll down the windows and turn off the AC.

Facts: Statements proven to be TRUE

That is ONE definition of facts. You need to stop drawing your conclusions based on one dictionary definition. Words in English are dynamic.

What about having sex in the car knucks the car engine ?

That number 5 though, are you sure?

UgoFly:
car fact 5: Since Buhari came cars have been more expensive.

This is a wide spread fact but however, one Galadima said people from Daura that beg for 2000 to go to Kaduna now own lots of cars. So there is a contradiction. it's just that most people don't know the right place to buy these cars

Where is the right place abeg?

Ok o. So Op if bullets are fired at a car's petrol tank you think it wouldn't explode?
Hmm. So why do petroleum tankers explode then? Do they have ignition too? Petrol no need any kind play o. Abeg!!!

Who else thinks a V10 or V12 sound better than a V8 engine?

Sound qualities are usually dependent on the frequency of the sound where high-frequency sounds are thinner in quality, and low-frequency sounds are thicker and fuller in quality. This explains to some extent why a V8 engine sounds better. However, let’ take a look at this with a deeper focus and see why this is so. Naijauto gives you this qualitative comparison of the sound of V8 vs v10 and v12 engines.

Bore size for the V8 cylinder - the bigger the better!
For an engine to sound very wholesome it has to be able to displace more fuel volume, the more the fuel displaced, the fuller and well rounded the sound is. It is a well-known fact that the cylinders of a V10 and V12 engines are more in number – just stating the obvious, but also of a fact is the bigger cylinders that are present in a V8 engine.

The cylinders in a V8 engine have more diameter individual than in the V10 and V12 engines. It therefore means that more fuel is available for displacement in a V8 engine, giving it a richer and better sound than that of V10 and V12. This explains why the V8 engine with its two banks of 4 cylinders as compared the two banks of 5 and 6 cylinders in the V10 and V12 respectively, sounds better.

The pistons' influence - sound effects ranges!
The pistons in a V8 engine are also designed to be bigger with a larger intake and exhaust valve commensurate with the size of bore in its cylinders. The pistons in the V10 and V12 engine on the other hand are designed to be smaller.

This is in order to ensure that the pistons are lighter and to produce higher revolutions per minute (RPM), which in turn translates to more power, giving the engine a boost to run faster. A higher RPM though does not translate to more displacement per revolution which means the sound of a V12 or a V10 engine will stand a chance of winning the sounding battle with a V8 engine.

Length of stroke – longer is better!
For a V10 or a V12 engine, they are designed to operate on shorter stroke movements with their small piston, while with a v8 engine, the pistons moved on a longer stroke movement with its larger pistons.

The shorter stroke movements in the V10 and V12 engines allow for a higher frequency in the engines and as a result produce a higher frequency sound which is not as good as that of a V8 that is deeper and wholesome.

Wrapping up V8 vs V10 and V12 engines
The factors mentioned above by Naijauto are the reasons why a V8 engine sounds better than a V10 or V12 despite its fewer numbers of cylinders. Though the V8 is seen more on the streets and even on Nigerian roads than the V10 and the V12 engine cars, is good to let V8 users know that they have a better deal in terms of engine sound. So if you are a V8 engine owner, know that you are not missing anything engine sound-wise.
