Question: Which Oil Is Thicker 5w30 Or 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..

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 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.

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.

Is it bad to put thicker oil in your car?

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 you put 10w 30 oil in a 5w30 engine?

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.

Can I mix 5w30 with 10w40?

As posted above, mixing 5w30 with 10w40 will give you an oil that performs somewhat better in the cold than 10w40, but less good cold than 5w30, and that has a viscosity a bit higher than 5w30 but a bit lower than 10w40. … Mixing different oils will not improve the performance or efficiency of the engine in any way.

Should I use thicker oil in an older 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.

Which is better 15w40 or 20w50?

The higher the number, the higher the viscosity. In XX-W-XX multi-weight oils, the low # reflects the cold viscosity, the high # reflects the hot viscosity. 20w50 is thicker at both low and high temps than 15w40.

Can you put 10w40 in a 5w30 engine?

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.

Is 10w40 good for high mileage?

High mileage protection Mobil Super High Mileage 10W-40 uses a combination of synthetic and conventional high quality base oils combined with modern performance additives to help provide long engine life and outstanding protection for vehicles with more than 75,000 miles.

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.

Which is thicker 5w30 or 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.

What oil is thicker than 20w50?

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 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.

What is a thicker oil than 5w30?

5w30 is used for light-duty engines while 10w30 is used for engines which carry heavier loads. 10w30 provides sealing action in the engine due to the fact that it is thicker than 5w30 engine oil.

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.

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.

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.

Can I mix 20w50 with 10w30?

No, you’ll be fine. I swear I didn’t know. If you mix viscosity grades such as a 10W30 low-viscosity oil and a 20W50 higher-viscosity oil, it is reasonable to expect that the resulting product will have viscosity characteristics which are thicker than the 10W30, but thinner than the 20W50.
