Should I Use 20w50 Oil?

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 is better 10w40 or 20w50?

the huge problem is the other number though. The smaller number, (the 20 part of 20w-50) describes how the oil behaves at 40 deg C and a 20w at 40 deg C is about 10 times thicker than your engine wants. A 10w-40 is better at around 6 times thicker and a 0w-40 is much better at about 4 times thicker.

When should I use 20w50?

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.

Does thicker oil help with burning oil?

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.

Which is the best engine oil?

Mobil 1Our pick for the best motor oil is Mobil 1 High Mileage 10W-30 Motor Oil. It’s one of the best synthetic oils for high-mileage vehicles, reduces leaks, and minimizes sludge buildup. For a less expensive option, consider the Valvoline High Mileage Synthetic Blend Motor Oil.

What is the thickest car oil?

The thickest viscosity grade for automotive applications is a SAE 60 which has a viscosity between 21.9 and 26 cst at 100c. Pretty thick stuff. Used in older engines, large Diesel engines.

When should I use 10w40 oil?

Overall the 10W30 will be the more appropriate oil for cold weather and non-performing engines while 10W40 is perfect for warmer temperatures and older vehicles.

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 oil instead of 5w30?

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.

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 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 happens if engine oil is too thick?

If you use too thick of a motor oil for the conditions, your fuel mileage will likely suffer. This is because the thicker oil increases resistance on moving parts such as pistons. While your engine will be protected, it will be at the expense of more frequent trips to the gas station.

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.

Which is better 10w30 or 20w50?

But what’s really important is that you use the oil viscosity the owner’s manual recommends. … So, 10W30 oil has less viscosity (flows easier) when cold and hot than does 20W50. Once the engine is running, the oil heats up.

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. The thickness is not meant for daily, older vehicle use.

Is 20w 50 oil thick?

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. Most modern oils are 10W40 or even 5W40.

Does thicker oil cause higher oil pressure?

Yes thicker oils will increase oil pressure, but will reduce engine horsepower. Excessive oil pressure may explode the oil filter, damage seals, blow out oil passage plugs or even damage bearings.

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.

Does thicker oil protect?

Engine oil viscosity Thin oils reduce friction in engines and help engines start quickly during cold weather. Thick oils are better at maintaining film strength and oil pressure at high temperatures and loads.

What oil is best for older engines?

Full synthetic oils are always a good choice for older vehicles that have been used a lot. They are perfect for lubricating motor parts as they do it much better than any other oil.

Can I mix 20w50 with 10w40?

Re: 20w50 and 10w40 mix The filter holds a good amount of oil, so yes, you will be mixing two different grades of oil which can lead to it congealing and cacking up all your oil ways.
