A Comparison between Royal Purple 75W90 VS 76W140
Viscosity
The debate of whether to use 75W90 or 75W140 oil for your car is one that has been around for a while. Many people swear by the 75W90 oil, while others find that the 75W140 oil is the way to go. So, which one should you use?
One of the main differences between the two oils is the viscosity. The viscosity of an oil is how thick or thin it is. The 75W90 oil is thinner than the 75W140 oil. This means that it will flow more easily and be less likely to cause problems.
The 75W140 oil is thicker, which means that it will take longer to flow. This can be an issue in cold weather, as the oil will take longer to reach all of the parts of the engine. However, the thicker oil will also provide better protection for the engine.
So, which one should you use? It really depends on your personal preferences and your driving habits. If you live in a cold climate and do a lot of stop-and-go driving, then the 75W140 oil may be a better choice. However, if you live in a warmer climate and do mostly highway driving, then the 75W90 oil may be the better choice.
Oil pressure
Royal Purple 75W90 is a synthetic motor oil that is designed to provide superior protection and performance in all types of vehicles. It is made with a high-quality base oil and a special additive package that helps to reduce wear, prevent corrosion, and protect against extreme temperatures. This oil is also designed to improve fuel economy and provide smoother shifting.
On the other hand, the Royal Purple 75W140 is a synthetic motor oil that is designed for use in heavy-duty applications. It is made with a high-quality base oil and a special additive package that helps to reduce wear, prevent corrosion, and protect against extreme temperatures. This oil is also designed to provide smoother shifting and improved fuel economy.
So, which oil is right for you? If you are looking for an oil that will provide superior protection and performance in all types of vehicles, Royal Purple 75W90 is a great option. If you are looking for an oil that is designed for use in heavy-duty applications, Royal Purple 75W140 is a good choice.
Composition
It is another important factor to consider while choosing between Royal Purple 75W90 VS 75W140. The 75W90 is a synthetic blend motor oil, while the 75W140 is a fully synthetic motor oil. The main difference between the two is the percentage of synthetic base oils used. The 75W90 is made up of 75% synthetic base oils and 25% petroleum base oils, while the 75W140 is made up of 100% synthetic base oils.
So, which one should you choose? It all depends on your driving habits and the conditions you typically drive in. If you do a lot of stop-and-go driving in hot weather, the 75W90 is a good option. It can withstand higher temperatures without breaking down.
If you do a lot of towing or driving in cold weather, the 75W140 is a better choice. It won’t thicken up as much in cold temperatures, so it will flow better and provide better protection for your engine.
Operating Temperature
The operating temperature of synthetic motor oil is important because it affects the oil’s viscosity. The lower the temperature, the thicker the oil becomes, and the higher the temperature, the thinner the oil becomes. The correct oil viscosity is important for proper engine operation.
Royal Purple’s synthetic motor oils are designed to operate over a wide temperature range. The 75W90 oil is designed for use in temperatures as low as -30°F (-34°C) and as high as 250°F (121°C). On the other hand, the 75W140 oil is designed for use in temperatures as low as -30°F (-34°C) and as high as 300°F (149°C).
The 75W90 oil is recommended for use in most passenger cars and light trucks. The 75W140 oil is recommended for use in heavy-duty trucks, buses, and off-road vehicles.
Price Per Quart
Oil prices are constantly changing, and as a result, there is no price you can always rely on to buy oil.
Different suppliers will have different prices, so it’s a good idea to shop around. That being said, you should be able to get a quart of this 75W90 oil for under $25 at most stores.
On the other hand, 75W140 oil costs more than the previous lubricant. A quart usually goes for around $65, although that number can vary significantly depending on where you buy it.

Frequently Asked Questions
Can you mix 75W-90 and 75W-140?
75W-90 and 75W-140 are both multi-viscosity gear oils, which means they are designed to perform well at a range of temperatures. It is generally safe to mix these two oils, but you may not achieve the desired performance results. For example, if you are trying to achieve the high-temperature protection of 75W-140 and mix it with 75W-90, the lower viscosity of the 75W-90 may negate the high-temperature properties of the 75W-140.
Can I use 75W-140 instead of 75W-90?
If your car’s manufacturer recommends 75W-90 gear oil, you can use 75W-140 gear oil instead. The higher viscosity of the 75W-140 gear oil will provide better protection for your car’s gears, but it may also slightly reduce fuel economy.
