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.
.
Also, can you use 20w50 instead of 5w30?
Choice between 20w50 and 5w30 oil. Limited to those two options and having the history of using the 20w50 I would have done as you did. Now you could also ask them to put 2 parts 5w30 with 1 part 20w50 to roughly approximate a thick 10w30 or thinner 10w40. However, that is not ideal.
Furthermore, is 20w50 thicker than 10w40? 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.
Thereof, what oil is more viscous 5w30 or 20w50?
The second number indicates the viscosity rating of the oil when the engine reaches operating temperature. This means that the 20W-50 is more viscous than the 5W-30 motor oil once the engine reaches the proper temperature for driving. Thicker oil generally lubricates engine parts better than thinner oil.
Is it OK to 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.
Related Question AnswersWill thicker oil damage my engine?
Higher parts temperatures, more wear. Too thick or too thin oils can both be bad for engines, but damage is neither immediate nor catastrophic; it just reduces overall engine life. Always use the oil recommended by the engine manufacturer.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.What is the thickest grade of motor oil?
The SAE grades go from Winter 0W to 60, (for flow at 100°C for the non-W range). 60 is the thickest oil, but most lubricating oils are now multigrade. A misguided anachronism some people use is oil “weight”, when “weight” has nothing to do with viscosity, especially with synthetic oils.What is the best 20w50 motor oil?

Will 20w50 increase 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.Why is 5w30 oil so popular?
The reason 5W-30 and 5W-20 motor oils are so common is because they work very well with a wide range of engines. Most often, these types of oils best cover the range of possible temperatures, with a 5W-20 oil more geared toward colder climates and a 5W-30 oil more appropriate for warmer temperature extremes.Does engine oil get thicker or thinner with age?
If the car saw repeated high-temperatures it will thicken as well. A good oil will thin slightly then thicken slightly. poorer quality oils will usually thin out of grade then thicken to 2-3x the viscosity of the virgin oil. Like the guys said, it may shear thin a bit, then after long use thicken.What are the pros and cons of synthetic oil?
Pros and Cons of Synthetic Oil- Molecular consistency. It is one of the major benefits of this type of oil.

In a 5W-30 for example, the number before the W describes the viscosity of the oil at low temperatures. The lower the number, the thinner the oil and the better the oil's cold temperature/ cold start performance. The number after the W describes how thick the oil is at the engine's normal operating temperature.Can you mix 5w20 and 5w30?
Yes, you can. It is best if they are from the same brand and level of API service to be the same formulas, but they are certainly compatible, even if different formulas and brands. I once needed oil on a trip, and my car had 5W-20n ILSAC approved oil in it as recommended by the factory.What oil is closest to 5w30?
