All Questions About 0W-16 Motor Oil (Detailed Guide)

Some automobiles require 0w-16 motor oil because of the improved fuel economy it delivers. Legislative mandates for improved fuel efficiency and fewer CO2 emissions have fueled the need for lower viscosity motor oils in consumer automobiles. However, this is not the sole reason; common viscosity oils, such as 0w-16, have been used in Japan since the 1990s.

The designing experts have authorized 0w-16 engine oil for engines that require it, based on the stricter tolerances employed in the engine design, and assessed that it is safe for the vehicle. Synthetic 0w-16 motor oil is available in a variety of viscosities. An engine must be developed specifically for this Oil to be used. In this article, we’ll go over All inquiries regarding the Best 0W-16 Motor Oil, what 0w-16 motor oil is, why it’s suggested, and which 0w-16 motor oil is the finest!

What Is The Source Of 0W-16 Oil?

Low viscosity oils, including 0w-16, have been used in Japan since the 1990s. Today it is only likely to become more common in North America and elsewhere, as its use of 0w-16 oil is already in many Toyota and Honda vehicles in North America.

Because of its unique properties, 0W16 has many advantages. This Oil, for example, can drastically enhance engine and fuel efficiency due to its low viscosity formulation. The formulation’s well-balanced ingredients help improve lubrication and prevent wear and strain. This light Oil is also suitable for freezing temperatures, as it allows for faster cold starts and lubrication in freezing temperatures. Finally, because this is a sophisticated detergent motor oil, it helps to remove harmful deposits and keeps the engine cleaner for longer.

Due to the increasing fuel-efficiency rules that will take effect in 2025, both import and domestic auto manufacturers will migrate to 0W16 in the next few years. According to various experts and lubricant oil manufacturers, lowering the viscosity by four points might improve fuel efficiency by up to 2%.

As new efficiency regulations are implemented, 0W-16 motor oil is becoming increasingly popular, but it is not yet available in all areas. As a result, I advise ordering from a reputable retailer.

Engine oil viscosity grades

Society of Automotive Engineers has invented a system for classifying engine oil viscosity. Two numbers describe the viscosity characteristics of oil in “cold” and “hot” operating modes. The introduction of oil additive technology has enabled this ability to have two values ​​of viscosity performance.

Cold temperature performance is expressed in “w” (for “winter”) and includes the first number on the rating scale. Five values are ​​related to ‘winter’ performance (0W, 5W, 10W, 15W, and 20W). The second number refers to high-temperature performance (100C) and has seven associated values (8, 12, 16, 20, 30, 40, 50).

Kinematic viscosity measures the time it takes for the oil to pass through a hole of a certain size at a given temperature; the thicker the oil and the higher the delivery number. Note that the grading scale is different for transmission or shaft oils, so direct comparisons are not recommended.

The high-temperature performance viscosity continued to decrease; the SAE decided to decrease in intervals of 4 instead of 5 to reduce confusion as the high-temperature numbers are now in the same range as the cold temperature (‘W’) performance number. The result is a lower-end high-temperature efficiency going from 20 to 16, then 8, and finally 4.

Is It Possible To Use 0W-20 Oil Instead Of 0W-16?

SAE 0W16 engine oil has outperformed SAE 0W20 engine oil in fuel economy. It allows you to start your engine quickly in cold weather. Some consumers may be concerned that its low viscosity will result in difficulties such as increased oil consumption and wear. Those issues, however, have been resolved. The 2018 Honda and Camry user manuals suggest that 0W16 is the best choice for optimal fuel economy and rapid cold-weather starting.

While there are no applications for SAE 0W16 in the United States Markets yet, they are on the way. Honda and Toyota will soon introduce more fuel-efficient engines in the United States, with other automakers following suit. Even though there are few existing uses for 0W16 engine oil, numerous lubricating oil manufacturers now provide it in the retail market. 

This is unlikely to harm engine performance, especially if it is not done often. However, it is a good idea to double-check this with your owner’s manual. Most automobiles that require 0w-16 Oil will also say in the owner’s manual that if 0w-16 is unavailable, 0w-20 Oil can be used instead (but replace it with 0w-16 at the following oil change).

Is 0w16 better than 0w20?

Generally, low viscosity oils are recommended to achieve better engine performance and fuel economy because thin oil flows easier and faster than solid oil.

Between 0w-16 and 0w-20, both are thinner grade oils. But oil with viscosity 0W-16 is thinner than 0W-20. Therefore, 0W-16 is more fuel efficient and ensures better engine performance. So this being the case, 0w-16 serves a better purpose.

However, some motors are optimized for 0w-20 to use, and in those cases, 0w-20 is better.

It all depends on the condition and what the manufacturer recommends.

Is 0w16 oil safe to install in Toyota Tacoma?

The recommended oil for Toyota Tacoma is 0W-20. Both 0W-20 and 0w-16 viscosities are thinner grade oils and are excellent for better fuel economy and cold engine starting.

Both are almost the same oils, except 0w-16 is a bit thinner. If it is an emergency, you can put 0w-16 in the engine but have to change it with 0w-20 at the next oil change. In addition to emergencies, you should always stick to the recommended viscosity.

Be sure to use “Toyota Genuine Engine Oil” or equivalent that Toyota has approved.

Is heavier Oil better?

Adults no longer worry that lighter oils offer less protection because the engine has changed. Most new engines have an oil pump that can handle lighter-weight oils.

Interchangeable oil pumps can deliver precise volume and pressure by using lighter-weight oils that create less drag on the engine. These pumps are much more complex and are usually electronically controlled. Consider actuators that control variable valve timing. If the oil does not have the right viscosity, it can cause sluggish actuators operation. It can then cause code errors and actuation problems.


Whenever oil is marketed and available to consumers, the vehicle’s fuel economy for window stickers is confirmed by the EPA. This prevents OEMs from using foreign lubricants for the engine oil, which can affect fuel economy.

With increasing fuel economy standards coming into effect in 2024, and according to some engineers and oil companies, a small four-point reduction in viscosity can improve fuel economy by up to 2%. So domestic and imported car manufacturers will switch to 0W16 in the future and then to 0W8.


As we strive for more fuel-efficient engines with longer lifespans, the market for automotive lubricants continues to grow. This can be seen in various ways, including developing synthetic and wholly synthetic motor oils. The Society of Automotive Engineers, or SAE, has established a range of new viscosity classes for 0w16 engine oil, one of the most intriguing regions. SAE 0W-16 is one of the more intriguing lubricants to hit the market in recent years. As this low-viscosity grade engine oil stands out on the shelves of oil providers, it is required for various automobiles.

A premium complete synthetic formulation is needed to achieve this low-viscosity grade. This innovative full synthetic motor oil has been used for over two decades because it enhances engine performance, reduces warm-up time, and offers superior engine protection.
