Question: What Is 20w 50 Oil Used For?

When should I use 20w 50 oil?

20-50 oil is an extremely viscous oil.

This oil is suitable for hot climates and will provide more protection in hot weather than 10-30 oil will.

20-50 oil is also a good choice for some older vehicles.

Since 20-50 oil is very thick, it may help prevent engine leaks in old cars..

Can I use 20w50 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.

Which is better 10w40 or 20w50?

Using the 20w50 in the summer is the best in the summer and the 10w40 is best in the winter. But it really doesn’t make much of a difference.

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 15w50 or 20w50?

The “20w50” means it flows like a 20-wt. when cold and protects like a 50-wt. when hot. The 15w50 obviously starts with a thinner base-stock with more VI’s and a has a broader temperature range.

Which is better 20w50 or 10w30?

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 thicker than 30w?

20w50 will be thinner when it is cold but at a 100 degrees it will be thicker than a 30 wieght.

What is 20w50 oil used for?

20W50 motor oil is a high viscosity oil that provides a cushioning and protects against metal-to-metal contact. It is also a more effective sealant than thinner oils. Both of these benefits extend engine life.

Is 20w50 good for high mileage?

Considerations. 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.

Will thicker oil damage 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.

What weight oil is best for high mileage?

Best Motor Oil for High Mileage Engines [4 Recommended Buys]Valvoline (VV150-6PK) MaxLife 10W-40 Higher Mileage Motor Oil. … Pennzoil High Mileage Vehicle Oil. … Mobil 1 45000 5W-30 High Mileage Motor Oil. … Castrol 06470 GTX 20W-50 High Mileage Motor Oil.

Which is better 20w40 or 20w50?

20W50 will hold on to the viscosity marginally better than 20W40 when the engine gets hot. However, 20W50 mineral oil will cause more sludge than a similar 20W40 because 20W50 will have more viscosity improvers. Pulsar 150’s manual recommends 20W40, but you can use either, not much of a difference.
