What motor oil is the thickest?

SAE50 is higher viscosity (thicker) than SAE40, and so on. Straight-weight oils come in a wide range of viscosities. But your car operates (ostensibly) in a wide range of temperatures. When your engine is running at operating temperature, it does not matter too much if it is summer or winter.

Is 20w50 thicker than 5w30?

An oil rated 5W-30 is a multi-viscosity oil that can be used over a range of temperatures. ... The number 30 means the oil will have a viscosity rating of 30 at 100 degrees Celsius. A 20W-50 oil is a heavier multi-viscosity oil appropriate for higher temperatures and higher loads, which require a more viscous oil.

What is the thickest motor oil you can get?

60 is the thickest oil in general use, but there are racing grades that go to 70. Most lubricating oils are now multigrade. There are now some additions to the table for very low viscosity, and these go in increments of 4 (4, 8, 12, 16) to distinguish from the 5 increment Winter grades.

Which oil is thicker 20w50 or 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.

Which oil is thicker 5w30 or 10w30?

10w30 is thicker than 5w30 because it has a higher viscosity in low temperatures. The engine oil will flow slower than 5w30 during the cold season. Thicker or higher viscosity metal oil has a better seal compared to low viscosity oil. Thicker oil offers better lubrication of motor and engine parts.

Is 20W-50 too thick?

20W-50 Motor Oil

It is highly recommended for older vehicles. The oil's density helps protect aging engine parts and helps prevent leaks that are common with older cars. It is important to note that 20W-50 oil may be too thick for many newer passenger cars and can cause serious engine damage.

What happens if 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.

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.

Will thicker oil damage my engine?

Using oil that is thicker than recommended may lead to a decrease in fuel economy, a higher load on your engine, and even a shorter life for your engine. Conversely, using thinner, lighter-weight oil than recommended can cause excessive wear and shorter life.

Is 10w 40 too thick?

10W40 oil has a higher viscosity, retaining more thickness than 10W30 as the temperature rises. In that case, 10W-40 motor oil would technically provide better protection against engine wear contact in higher temperatures.

What car uses 20w50 oil?

Suitable Vehicles

Depending on the recommendations for the particular vehicle, 20W50 oil is suitable for large or small diesel engines, gasoline engines, motorcycles and aviation vehicles. It is also suitable for both air- and liquid-cooled engines.

What happens if I use 20w50 instead of 10W30?

The main reason for using 20w50 is to slow down oil burning. If this is the case, using 10w30 would speed up the burning. I have had oil burners before, and used 20w50 in the summer, with no problem. But, your car will be hard to start in very cold weather with 20w50.

What happens if you 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.

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.

Is Thicker oil better for older engines?

You should switch to thicker oil if your older car is consuming oil. The general rule is to always use the viscosity your car manufacturer recommended. ... As your engine gets older, the clearances within the engine change due to wear and tear, and your car could start to consume oil.
