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.
Which oil is better 10W30 or 20w50?
Designations on the label — such as 10W30 or 20W50 — tell the oil's viscosity. In the owner's manual, car manufacturers recommend oils for the brand new vehicle, and 10W30 is commonly used in new engines instead of heavier oils. ... So, 10W30 oil has less viscosity (flows easier) when cold and hot than does 20W50.30 sept 2011
What happens if you use 20w50 instead of 10w40?
Using an oil of a higher viscosity as you mention, 20W-50 instead of 10W-40 can actually cause a higher rate of fuel consumption due to the fact that there is a greater resistance to flow. This greater resistance to flow can also increase engine operating temperature.
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.
What engines use 20W50?
20W-50 is a common motor oil used in moderate-to-large diesel and gasoline engines, high-performance motorcycle bikes, and aviation vehicles. Its resistance to thinning at high heat also makes it popular as a racing oil and high temperature driving.19 nov 2021
Which oil is best for petrol?
5W30 or 10W30: Ideal for modern petrol engines. It is cost-effective and has a low viscosity which fits well with modern age petrol engines and gives good fuel efficiency. 10W40: Available in mineral and semi-synthetic variants and is suitable for the Indian climate.8 sept 2019
Is 20W50 good for old cars?
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 is better 10w-40 or 20W 40?
10w-40 it's mean viscosity 10 when weather cold and viscosity 40 when hot. Similarly, viscosity 20 when cold and viscosity 40 when hot. 10w-40 can give better performance in replace of 20w -40 oil.
What is the difference between 10w-40 and 20W 50 motorcycle oil?
Now to answer your question a bit more simply, 10W40 is thinner than 20W50, both hot and cold. If both were 10W, then they would be the same cold, with the 40 being thinner than 50 when hot.
Will 20W50 hurt my engine?
A 20W/50 oil is much thinner at high temperature than a 5W/30 at a low temperature, so the viscosity will not hurt your engine.
