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 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 the wrong oil damage my engine?
The brand of motor oil matters little, but its viscosity grade (10W-30, for example) is important. Use only what the owner’s manual specifies. Using the wrong oil can lead to reduced lubrication and shorter engine life. If the manual says to use synthetic oil, do so.
Does 10w30 hurt 5w20 engine?

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.

Can I use 20w50 instead of 10w30?
So if you are in a cooler climate its better to stick with 10w-30, if that’s not available then you can use 20w-40 it will not damage the engine but it is not better.
