0w30 Vs 5w30 Motor Oil

Motor oil is an important part of a car’s engine. It makes sure that the engine operates smoothly and efficiently, but it also extends the engine’s life. These numbers refer to viscosity or how thick the oil is at any given temperature.

Why Compare?

The higher number represents a thicker type of oil that can be used in colder weather when there is less demand on your vehicle’s engine because it takes longer for components to wear down with use during these conditions. The lower number refers to thinner, more easily flowing oil that can be used in warmer temperatures with greater demand on your vehicle’s engine due to its high-speed operation under these conditions.

Most car manufacturers recommend a type of oil that has a viscosity rating somewhere between these two numbers since it can be used in either warmer or cooler temperatures without sacrificing the quality and efficiency of your vehicle’s engine. This is known as “multi-grade” motor oil.

Which oil you use will depend on your climate, the type of driving you do, etc., but there are many factors to consider when choosing which viscosity is best for your car’s model year. Just make sure you change your oil on a regular basis so that it can do its job effectively.

Main Difference

The major difference between the two motor oils is the viscosity of each oil. Viscosity refers to how thin or thick oil is at temperature, which will affect its ability to lubricate your engine and keep it cool under high heat conditions.

A lower number for this rating means that the oil will be thinner, which is perfect for cooler temperatures like 0W30 Motor Oil. At the same time, a higher number will mean that it is thicker, which means it’s best for warmer temperatures like 5W30 Motor Oil.

Can I Use 0w30 Instead Of 5w30?

Depends on your application. If you are looking to use the 0w30 as a daily driver and you don’t care too much about turbocharger or supercharger longevity, then yes. However, if your car is boosted and you’re worried more about engine power and durability, no. The viscosity (0W vs 5W) is a huge factor when deciding to use 0w30 in place of 5w30 for your daily driver.

The ‘0’ denoting the absence of VIOC (Viscosity Index-Optimized Conventional Oil) means that the oil will thin out on its own on multiple occasions, causing poor lubrication, leading to bearing and engine failure. Even though 0w30 oil has the same viscosity as 5w30 at operating temperature, it lacks VIOC meaning it is naturally thinner and will thin out much easier.

This will lead to poor lubrication and bearing wear at startup from increased slipping between parts and a much higher risk of engine failure because of a lack of lubrication during operation. On an engine under boosted conditions, the issue isn’t so many high temps but low temps. The lower the temp, the more VIOC is needed to reduce bearing wear and help keep viscosity up in cold weather. In short, 0W30 Motor Oil is perfect for cooler temperatures and 5W30 Motor Oil is best for warmer temperatures.

0w-30 Synthetic oi Short Review

0w-30 synthetic oil is the aforementioned synthetic blend that replaces conventional oil at startup until the engine reaches operating temperature. 0W30 motor oil, 5W30 motor oil will provide excellent protection at high temperatures because VIOC (Viscosity Index Optimized Conventional Oil) provides shear stability and deposit control.

Why Use 0w30?

0w30 motor oil is perfect for warmer weather because of its naturally lower viscosity, but it’s also an excellent choice for cooler temperatures. Although the 5W has a higher viscosity rating than 0W at startup (cold temps), it lacks VIOC to protect your engine under colder operating conditions (cooler temps).

When Should You Use 0w30 Over 5w30?

If the engine is started at cooler temperatures or starts cold under conditions, that can result in premature wear. 0w30 oil should be used whenever possible because it’s thinner, better for startup protection, and contains VIOC to protect engines under colder operating conditions.

The only time you should NOT use 0w30 is when the oil viscosity is excessively low (i.e less than -45c). You run the risk of lubrication breakdown and bearing wear at startup and engine damage due to lack of protection under colder operating conditions.

Note: When using Viscosity Index Optimized Conventional Oil (VIOC) in cold weather, the oil’s viscosity will be lower than what is stated on the bottle.
