Question: Can I Use 10w30 Instead Of 20w50?

Which is better 15w50 or 20w50?

20W50 will maintain its viscosity for longer running than a 15W50.

Ofcourse, everybody knows that 15W50 viscosity is better suited than 20W50, but practically, because of more shearing in case of 15W50, 20W50 is better and that is why most companies make 20W50 and not 15W50 when it comes to mineral oils..

Will heavier oil hurt my engine?

Not only that, but the engine will waste energy pumping the thicker motor oil, reducing fuel economy. Since thicker oils don’t transfer heat as well as thinner oils, operating temperatures will increase, too, possibly leading to accelerated chemical break down and harmful sludge and deposits.

Can I use 20w50 instead of 10w40?

As per Z32 fsm,10W40-20W50 is recommended if the car is driven fast,raced,or in driven in hot climates,and 10W30 is recommended for fuel economy only.

What is 20w 50 oil used for?

SAE 20w-50 Oil – Conventional & High Mileage A SAE 20W-50 motor oil is typically used in older vehicles or in particularly warm climates. Castrol GTX 20W-50 has been specially formulated to help extend the life of your engine by keeping it free from sludge, even when operating in extremely high temperatures.

Which oil is thicker 5w30 or 10w40?

A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.

Is mixing 5w30 with 10w30 bad?

Yes, if topping up. If your oil must be topped up, then you are burning oil already, so the difference won’t cause more damage than is already there. 5W30 and 10W30 are essentially the same at operating temperature.

Does it matter if you put 10w30 instead of 5w30?

Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine. 5w30 and 10w30 engine oils have close viscosity, and thus there is no harm in mixing them.

What does 20w50 oil mean?

20W means that this oil behaves exactly like a 20 weight oil at 0F, … and behaves like a thicker 50 weight oil at 210F. This type of oil is called a multi-viscosity oil because it is capable. of lubricating your engine under a wide range of temperature conditions.

What oil is best for older engines?

When you’re choosing the best oil for older cars or high mileage engines, there are several criteria you can look at.Pennzoil High Mileage Conventional Motor Oil. … Castrol GTX Part-Synthetic High Mileage. … Valvoline MaxLife High Mileage Synthetic Blend. … Mobil1 High Mileage Engine Oil. … Amsoil Premium Protection Motor Oil.More items…•

Which oil is best for high mileage engines?

5 Best Motor Oils for High Mileage Engines#1 – Mobile 1 High Mileage Synthetic Oil.#2 – Royal Purple HMX Synthetic Oil.#3 – Mobile Super High Mileage Synthetic Oil.#4 – Castrol GTX High Mileage Synthetic Blend Oil.#5 – Pennzoil High Mileage Synthetic Blend Motor Oil.

Should I use thicker oil in a high mileage engine?

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.

Will thicker oil stop oil burning?

A lot of oil-burning takes place because an engine’s piston rings are worn out, and thicker oil won’t fix that. Using thicker oil is also a particularly bad solution for modern cars. … They use low-viscosity oils that splash easily all over the moving parts of the engine to make sure they’re all lubricated.

What happens if I put 10w40 instead of 5w30?

If you use 10-w-40 instead of 5-w-30 specified by the manufacturer then the viscosity of 10-w-40 used by you will be higher and oil thicker than what is specified during winters. Similarly the oil viscosity will be higher and oil thicker than specified during summers.

Will 20w50 increase oil pressure?

With 10w30 the engine will produce a maximum of 55 psi of oil pressure at operating temperature. With 20w50 racing oil and the same operating conditions, it will produce 70 psi of oil pressure.

Is 20w50 good for high mileage?

The viscosity level of engine oil 20W50 is geared toward racing engines, as opposed to high-mileage engines, that run extremely hot and need heavy load operation. … Since its viscosity is so great, it can drag down the functioning of the crankshaft, resulting in less horsepower.

Should I use 20w50 oil?

20W50 motor oil is suitable for warmer climates, where the higher temperature causes the oil to thin. It is also useful for vehicles subject to hot temperatures and for those used for high-stress activities such as hauling or pulling trailers.

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.

What oil is more viscous 5w30 or 20w50?

A 5W-30 oil is commonly used in passenger cars for normal use throughout the year. A 20W-50 oil will not protect a car as well in a cold winter and its greater viscosity will increase drag and friction in a passenger vehicle.

What happens if I 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.

Is 20w 50 thick oil?

The “20W” indicates how quickly the engine will start when cold or in cold weather. The “50” refers to the thickness of the oil when the motor has been running for a while. 20W50 motor oil is relatively viscous and thick.

Can I use 5w30 instead of 20w50?

20w50 is actually thicker than 5w30. This will result in less fuel efficiency, less horsepower, and more engine damage because it will have to work harder to rotate. Trust the engineers that made your vehicle.
