Is 0W16 good oil and how is it different than 0W20?

Pennzoil Platinum 0W-16 Fully Synthetic Engine Oil is designed to maximize performance and improve fuel economy in modern engines. Pennzoil Platinum 0W-16 with PurePlus technology reduces wear when starting idling to save fuel and provide maximum engine performance.

What is 0W16 oil?

You could have noticed that some Honda and Toyota four-cylinder cars require SAE viscosity 0W16 Oil. These oils stand out on a shelf as the last number is strange because it does not end in a five or zero. The 0W16 oil has been around for around two decades in Japan. It is an oil designed to increase engine efficiency and decrease engine warm-up time.

SAE 0W-16 is a low-viscosity oil that has recently entered The United States for the first time with the introduction of the 2018 Honda Fit and the 2018 Toyota Camry 2.5L Four-Cylinder model. SAE 0W-16 oils can offer additional fuel economy benefits compared to higher-viscosity oils; Japanese car owners have used them for a long time.

Are SAE 0W-16 motor oils fully synthetic?

Yes, 0W-16 motor oil is fully synthetic with Pure PlusTechnology. To achieve this lower viscosity, we need a fully synthetic formulation, the most outstanding Pennzoil Platinum SAE 0W-16 Full Synthetic Motor Oil.

What is the difference between 0W16 and 0W20?

0w-20 and 0w-16 Oils are both low viscosity oil, which is highly fuel-efficient. These lighter viscosity oils are very suitable for modern engines designed for low viscosity oil to use. 

Both the oils perform exceptionally well in extremely cold temperatures and provide immediate circulation through the engine. Based on a few things, we will try to help you understand the difference between 0w-20 and 0w-16.

Suitable Weather to Use 0w20 & 0w16

0W-20 and 0W-16 are multigrade SAE oil especially suitable for colder climates. These oils easily lubricate crucial engine parts immediately and provide good cold-start performance.

However, 0w-16 is a little thinner than 0w-20, thus having better cold start performance than 0w-20. Although both oils are great to use in winter, 0w-16 has a slight edge in freezing temperatures. 

On the other hand, 0w-20 provides better lubrication than 0w-16 in hot weather as it is slightly more dense than 0w-16. Sometimes the oil can be too thin, causing premature wear in different engine parts. Thicker oil creates a better lubricating film between high-speed metal parts of the engine than a thinner one. That’s why 0w-20 works better at protecting engines in high temperatures than 0w-16. 

Fuel Economy 

Since 0w-16 and 0w-20 are lower viscosity oils, both are impressively fuel-efficient. In the modern era of engine lubricants, the requirements and demands for engine fuel efficiency increase to lessen the environmental pollution. Engines running on thicker oil burn more fuel than thinner oil does.

So, the significant difference between 0w-16 and 0w-20 is that 0w-16 is a little thinner oil than 0w-20 at high outside temperatures and the engine’s operating temperature. Although 0w-20 is excellent for fuel economy, 0w-16 is even more fuel-efficient.

Outside Temperature

Because both 0w-20 and 0w-16 are lower viscosity oil, they specially perform effectively in colder climates. However, as thinner oil is less protective to the engine, these oils are optimized for certain modern vehicles designed to get maximum fuel economy and protection.  

0W-16 oil can easily flow at ambient temperatures as low as -40°C, while 0W-20 can also flow typically down to -30°C. Since both are multigrade oils, they can operate and protect the engine at relatively high temperatures.

However, when it is hot, 0w-20 viscosity oil is more capable of lubricating the engine than 0w-16 is. 0w-20 can operate well up to 25°C, while 0W-16 can operate and lubricate engine parts reliably up to 20°C. 

Difference In Price

If you compare 0w-16 and 0w-20 viscosity oil in terms of price, 0w-16 is expensive. Oil being too thin makes it excellent for fuel efficiency. However, thinner oil is not good at lubricating and protecting the engine’s moving parts.

So, thinner oils are manufactured to provide maximum fuel efficiency and protection. Until now, 0w-16 is probably thin and requires chemicals designed to protect the engine properly. That’s the reason it costs more than 0w-20.

Nevertheless, there are many other factors in deciding how an oil price should be apart from viscosity. For example, synthetic oil costs more than traditional oil due to its uniform molecular structure. 


0w-16 and 0w-20 viscosity oils are generally used for modern gasoline and petroleum engines, especially in cold regions.

These thinner oils are primarily optimized to provide higher fuel economy. Car manufacturers in Japan have been experiencing and recommending these thinner oils for use in their automobiles.

Even today, some Japanese cars, such as Toyota and Honda’s four-cylinder vehicles, require 0w-16 oil for their cars. Nonetheless, as the global demand for engine fuel economy is rising, more European cars will too start recommending thinner oil such as 0w-20 and 0w-16 shortly.

Can we use an SAE 0W-16 motor oil in an engine for which a heavier-viscosity oil?

No. You should always observe the vehicle owner’s manual to determine your engine’s correct motor oil specification, oil drain interval, and viscosity grade.

Are SAE 0W-16 motor oils suitable to use in turbocharged engines?

Yes, if you have a vehicle with a turbocharged engine and your owner’s manual tells you to use SAE 0W-16 viscosity grade. Pennzoil Platinum 0W-16 Full Synthetic Motor Oil product is designed to protect the turbocharged engines against LSPI.


0w-16 and 0w-20 are low viscosity, thinner oils that will become the future of engine lubricants. Although 0w-16 and 0w-20 maximize engine fuel efficiency and have other benefits, using them in your car without prior knowledge of whether. Or not they are appropriate for your vehicle might cause severe damage to your engine. Thinner oil is so poor at lubricating the engine parts properly in high temperatures.
