Is 5W or 0W better?
The first number of a multi-grade oil designates the ability for the oil to be pumped and flow at colder temperatures; the “W” stands for winter. Thus, a 0W oil will be able to flow faster and get to critical engine components better than a 5W or a 10W oil; especially in extreme cold conditions and at engine start-up.
Is 5W-30 and 40 the same?
Although both have the same viscosity grade in cold weather, 5W-40 is thicker than 5W-30 at warmer temperatures. Here’s what the viscosity grade means: The first number is the oil’s cold weather viscosity grade.
Can 5W-30 be used instead of 0W 30?
A 0W-30 grade can operate at much lower temperatures than a 5W-30 as the oil will flow faster thereby protecting the engine at an earlier stage. Some engines are not suited for a 0W-30, always check your owner’s manual before adding oil to your engine.
What is 0W 40 oil used for?
0W-40 motor oil. 0W-40 oils are recommended by automakers for many types of European vehicles, including Mercedes-Benz, Porsche and Volkswagen. The viscosity is gaining popularity with American automakers for high performance engines in both cars and pickup trucks.
Can I put 5W-30 instead of 0W-40?
Can I Mix 0W-40 With 5W-30 Engine Oil? Yes, if your car manufacturer approves it. If not, you should only use the approved oil. 0W-40 and 5W-30 oils can be combined because 5W-30 is thicker oil than 0W-40, and the extra, lower viscosity will make the start-up oil flow easy and efficient.
Can I use 5W 40 instead of 5W-30?
In practice, this means that each oil is just as viscous at lower temperatures and will remain viscous at -30°C, however 5w40 oil outperforms 5w30 oils at higher temperatures, being effective up to ambient temperatures of 50°C, as opposed to 30°C.
When should you use 5W-30?
5w30 oil is particularly well suited for cars driven in cold climates. Unlike oils with a higher hot temperature rating such as 10 or 15, 5w30 oil can flow freely enough when the engine is started at low temperatures to coat and protect the engine’s internal components.
