What Happens If You Put the Wrong Oil in Your Car?

The lifeblood of any vehicle engine is motor oil. It ensures that your automobile runs smoothly. It must go without saying that when it comes time for such changing the oil, one must use the type of fuel that the automobile manufacturer suggests, given the significance of motor oil. But what happens if you put the wrong oil in your car?

What Happens If You Put the Wrong Oil in Your Car? Utilizing the incorrect oil, a vehicle’s lubricating may be diminished, and its lifespan may be shortened.

It’s typical for individuals to start mixing or utilizing the incorrect fluids in their vehicles, and the consequences can range from uncomfortable to fatal. We’ll look now at the possible harm that using the wrong engine oil could bring to the automobile in today’s article.

Engine oil: What is It?

The vital substance that keeps the engine inside the automobile running is engine oil. Vehicles couldn’t operate without that.

Engine oil, commonly referred to as fuel oil as well as motor lubrication, is a thick liquid that is made by distilling crude oil and is utilized to lubricate mechanical parts. The essential oil and additives are the two main components.

Because there are so many moving components in engines, resistance may be produced. A motor, as well as its interior elements, can operate thanks to the engine oil’s various functions effectively.

But the lubrication of a vehicle’s moving components is its primary purpose. Coating and safeguarding moving parts, regulating temperature, closing, and lowering friction are all additional crucial roles.

What Happens If You Put the Wrong Oil in Your Car?

Do users understand the potential consequences of a transfusion of the incorrect blood group? It may be deadly; your judgment is as accurate as ours. The same can be said of motor oil, which is thought to be the vehicle’s lifeblood and may have disastrous results if the wrong kind is used.

However, the viscosity class of the gasoline is crucial, not the branding. Use just what is recommended in the instruction booklet. Use synthetic oil, as directed, if the handbook so requires. Contrary to popular belief, mixing synthetic oil with ordinary oil won’t affect the engines, although there isn’t any advantage to doing so.

What Happens If You Put the Wrong Oil in Your Car? Symptoms

1. Cold Temperature Makes Starting Difficult

You could not be capable of starting your automobile in extremely low weather, whereas the oil has an excessively high cold viscosity or is overly heavy. This situation results in an excessive reluctance to start the automobile because the oil becomes too heavy to grease all moving components adequately.

2. Oil Spills

In older or heavy-usage vehicles, using synthetic gasoline may cause tiny oil leaks that wouldn’t have occurred with conventional oil. White smoke rising out from the tailpipe and oil spills pooling beneath the car may indicate that you have used the incorrect oil, so be aware of these indicators.

Synthetic oil may fit through smaller spaces than ordinary oil because it has various flow properties that traditional oil lacks.

Although using synthetic oil in such circumstances won’t always result in harm, you could observe oil drips on your basement floor or even a smoky smell when driving. You should be highly aware of the liquid level and fill it off as necessary since this oil is gradually leaking.

3. Notice a Burning Oil Odor

Whereas if motor oil doesn’t have a high sufficient hot viscosity, it might begin to degrade in extremely hot circumstances and improperly lubricate engine parts. The effect would be the burning of the oil.

The excessive friction created by the metal-on-metal contact might eventually cause long-term harm to the engine. Because synthetic oil is used and leaks, as was already explained, you could also scent gasoline vapors.

4. Inefficient Fuel Usage

The fuel economy will decrease if you employ motor oil that is too heavy for the circumstances. This would be due to the heavier oil creating more resistance for moving elements like pistons. However, it will lead to widespread excursions to the filling station at the price of protecting the engine.

A rapid decline in fuel efficiency following an oil change may indicate that the incorrect oil has been used, despite the fact that a reduction in motor output associated with too-thick lubricating oil might be difficult to notice.

5. An Engine that Rattles in the Cold

Your vehicle could make a ticking sound if you utilize motor oil that is too light for the circumstances. Usually, this will sound the highest when the car starts up and will progressively go quieter after some time spent driving.

This occurs because the incorrect quantity of engine oil may not adequately coat and lubricate all engine parts. The sound you hear is the collision of metal parts like valves as well as valve keepers. The issue could be resolved by briefly shifting to different viscosities.

6. Less Effective

The engine’s fuel economy might decrease if you utilize motor oil that is viscous at a greater level than is advised. This is due to the possibility of increased friction amongst moving parts caused by the heavier oil.

Despite having “lubricated” and shielded, this renders it difficult for them to operate. It takes careful balancing to ensure that a moving item is both covered and not hampered while at the exact moment.

7. Lessening in Motor Life

Too much motor oil will prevent it from flowing into places where finer oil would. When it occurs, the resultant metal-on-metal friction will begin destroying engine components. The shear resistance needed by your motor, however, might not be there in oil which is too light.

That could result in lower oil pressure as well as metal-on-metal friction. To sum up, using the incorrect oil might lead to less lubrication as well as a shortened lifespan for the engine.


Before adding additional fluids to any vehicle’s undercarriage, customers should consult their seller’s handbook. If someone is unsure, they must consult a technician or even the staff at their neighborhood automotive parts shop.
