Will thicker oil damage my engine? – AnswersToAll

Will thicker oil damage my engine?

Higher parts temperatures, more wear. Too thick or too thin oils can both be bad for engines, but damage is neither immediate nor catastrophic; it just reduces overall engine life. … Always use the oil recommended by the engine manufacturer.

Will the wrong oil damage my engine?

Incorrect viscosity can also cause metal-on-metal friction, leading to the breakdown of engine components. … Using the wrong motor oil can lead to serious damage that will require costly repairs.

Can you put 5w20 oil in a 5w30 engine?

Synthetic engine oils are flexible, which means both 5w20 and 5w30 work equally well to protect your vehicle’s engine despite the climate. But if you still find yourself wondering which motor oil to choose between 5w20 vs 5w30, we recommend you go with 5w30.

Does oil get thicker or thinner when hot?

If it flows slowly, it gets a high rating. Your engine needs oil that is thin enough for cold starts, and thick enough when the engine is hot. Since oil gets thinner when heated, and thicker when cooled, most of us use what are called multi-grade, or multi-viscosity oils.

Can you mix 5w20 and 5w30?

Can I mix 5W20 oil with 5W30 oil? Yes, you can. It is best if they are from the same brand and level of API service to be the same formulas, but they are certainly compatible, even if different formulas and brands.

What happens if I use 5w 20 instead of 5w 30?

In your case, where you need 5W-20 instead of the recommend 5W-30, yes it does make a difference. Engine oil is effectively a giant system of fluid bearings. This means that the surfaces within your engine don’t actually touch, there is a thin wedge of oil between them. … Your engine will wear out faster.

What happens if you put 5w 20 instead of 5w 30?

Due to the increased resistance of the thicker 5W-30 oil, your engine will produce slightly lower fuel economy and horsepower output. You also risk engine damage when using 5W-30 instead of 5W-20, as the internal engine components are specifically designed to be used with 5W-20 motor oil.

Is Thicker oil better for older engines?

A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil — 10W — can help protect worn engine bearings as well.

Is it OK to use 10w40 instead of 5w30?

Your vehicle does not use 5W-30 oil. The recommended oil viscosity for your vehicle, according to Kia documentation, is 10W-40. If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.

Can the wrong oil cause overheating?

Hot temperatures alone might not be causing your vehicle to overheat. … A vehicle’s thermostat is responsible for regulating the amount of coolant flowing through the engine. A broken or malfunctioning one can easily cause your car to overheat. Low Oil: A car’s oil does more than just lubricate moving parts.

Does it matter what type of oil I put in my car?

You should use synthetic oil if you car manual instructs you to do so but otherwise, it won’t matter too much. Any oil used should be multi-grade, however.

What happens if you dont use synthetic oil?

Synthetic oils don’t break down as easily as conventional oils, so they protect your engine components from friction, wear and tear, and ultimately break down for longer.

Can you go from synthetic oil to regular?

Answer. Synthetic oils typically provide better protection than conventional oils, but switching back and forth between full synthetic and conventional oil will not damage the engine. Of course, this depends on the current engine condition and the quality of the conventional oil being used.

Is SAE 5w 30 a synthetic oil?

The petroleum base oil alone may have the properties of an SAE 5 grade oil. This means at extremely low temperatures, it may be thick, and at high temperatures, it’s fairly thin. … When it’s brand new, a 5W-30 conventional motor oil acts exactly like a 5W-30 synthetic motor oil.

Can you mix engine oils?

According to Mobil Oil, it should be fine to mix oils. … Many oils are a blend of natural and synthetic oils. So, if you are low on oil, don’t be afraid to add a quart or two of synthetic oil if you are using regular oil or even regular oil if you are using a synthetic.

Does thicker oil protect?

Within reason, thicker oil generally seals better and maintains a better film of lubrication between moving parts. At the low-temperature end, oil has to be resistant to thickening so that it flows more easily to all the moving parts in your engine. … A 5W oil is typically what’s recommended for winter use.

Is it OK to mix 5w30 with 10w30?

If your car contains a typical multi-grade oil, such as 5W-30 or 10W-30, you can use most any multi-grade oil to “top off” your oil and bring it up to a proper level. Mixing the viscosity of oil has no effect on the engine. 5W30 and 10W30 are very close in viscosity.

Can I mix oil viscosities?

It is always advisable to not mix motor oil brands, however, different viscosity grades of the same brand motor oil are compatible. … But there’s absolutely no danger about incompatibility resulting from mixing engine oils,” Miller says. “We’ve tested all of our grades and brands, and we haven’t observed any problems.”

Is higher viscosity oil better?

Thin oils have lower viscosity and pour more easily at low temperatures than thicker oils that have a higher viscosity. … Thick oils are better at maintaining film strength and oil pressure at high temperatures and loads.

When should you get your oil changed?

“Change your car’s engine oil every three months, or 3,000 miles.”

What does SAE stand for?

SAE stands for the Society of Automotive Engineers. The SAE was founded in 1905 by Andrew Ricker and Henry Ford. At the outset, its sole aim was to provide an umbrella organization for the scattered automotive engineers who usually worked alone in various parts of the country.
