Question

Can I use 5w30 oil instead of 5w20?

It is always advisable to use the engine oil recommended for your car to ensure a longer life for the engine parts. The oil change can destroy the powertrain warranty on your automobile, lower engine performance, and ultimately may harm your engine.

Motor oils are graded based on their viscosity. 5w20 and 5w30 engine oils are commonly used in colder temperatures. It is usually recommended for older engines and light-duty use. This is because an oil with a higher rating implies that it is thicker and suits engines that run hot easily.

What is 5w30 oil?

5w30 oil is a multi-grade oil commonly used in light-duty petrol and diesel engines. With a viscosity level ranging from 5 to 30, the oil flows well in cold and hot conditions, thus protecting the engine from wear and tear.  

What is 5w20 oil?

5w20 oil is also a multi-grade oil specifically designed for vehicles running in low-temperature conditions. Like 5w30 oil, it is used widely in light-duty petrol and diesel engines. 

Can you use 5w30 oil instead of 5w20 oil?

It is always advisable to use the engine oil recommended for your car to ensure a longer life for the engine parts. The oil change can destroy the powertrain warranty on your automobile, lower engine performance, and ultimately harm your engine.

Mixing different oils will never lead to faster performance. Instead, it may speed up the engine’s wear and tear. So, even if your engine allows the mixing of oils, there won’t be much performance improvement. To prevent problems, always use one viscosity rating at a time.

However, the selection of oils also depends on the driving conditions your car is exposed to. 5w30 oil is ideal for driving in warmer areas too. It has a higher viscosity index and warmer temperature range than 5w20 oil. 5w20 is suitable for chilly areas. It’s for light-duty engines that don’t get hot. Also, 5w20 oil has good cold-start performance.
