Does having no oil/thinner oil make an engine feel more revvy/lively?


Will thinner oil damage engine?

It’s best to use the oil viscosity recommended in the owner’s manual, but using a slightly thinner or thicker oil (lighter or heavier viscosity) generally poses no long-term harm.

Is it better to use thicker oil in older engines?

Older engines use more oil, but it gives them a better fuel economy. Older engines with more than 75,000 miles on them require a thicker oil that will lubricate their critical engine parts and prevent oil leaks, sludge, and deposits from forming.

When should I use thicker oil?

There are some circumstances where drivers have used thicker oil in an engine. If, for instance, clearances between engine components have increased, gotten sloppy, a thicker oil can help to fill the void. Within reason, thicker oil maintains a better lubricant film between moving parts.

What happens if you use a higher viscosity oil?

Using motor oil with higher viscosity (oil that is too thick) also reduces your car’s overall fuel efficiency. This is because the thicker the motor oil, the higher its resistance on vital metal components, such as pistons.

Is 10w40 better for older cars?

The 10w30 and 10w40 oil options are both acceptable for your car, but if you have a high mileage car, you should use the 10w40 oil. Older engines are able to handle higher temperatures and wear and tear more efficiently with thicker oil. Your engine will last longer if you use thicker oil.

Will 10w40 hurt a 5W30 engine?

It is not a problem to maintain your vehicle with 50W-30 oil. If you are using an all-synthetic oil, the recommended viscosity is 10W-40, according to Kia documentation. Using oil that is as cold as 32 degrees, but not more than 10W-40, is perfectly fine. Even during extremely cold temperatures, 5W-30 may be better.

Is synthetic oil good for older engines?

It protects better, performs better, and lasts longer, and it’s no longer made with a chemical compound that could hurt older vehicles. Modern synthetic oil is safe to use in all types of vehicles, ranging from new purchases to classics to aging not-so-classics.

Which oil is thicker 5w30 or 10w40?

The 5w30 oil is much thinner than the 10w40 oil and on the other hand, the 10w40 oil is much thicker than the 5w30 oil. The viscosity of 5w30 at low temperatures is 5 whereas the viscosity of 10w40 at low temperatures is 10.

What happens if you use the wrong oil?

You might notice a few oil spot in your garage or under your car because using the wrong oil can lead to leaks, or you might become aware of a burning smell while driving. If the oil isn’t working as it should engine parts might not be lubricated well enough and cause friction, which can burn the oil.

Does thinner oil run cooler?

The viscosity of thin oils is lower than that of thicker oils, which makes them easier to pour at low temperatures. The thin oils in engines reduce friction and help them start faster when the weather is cold.

What happens if I put 10w30 instead of 5w30?

What Happens If I Put 10w 30 Instead Of 5w 30? Synthetic oils will mix perfectly, as long as they have the same chemical composition. As a result, mixing 10w30 and 5w30 is not a problem since one will be topping up.
