All types of vehicles, from motorbikes and generators to automobiles and other machinery, utilize motor oil. In addition to preventing wear in the engine’s moving parts, these lubricants will also help keep your engine running smoothly. The quality of your engine’s oil can tell you a lot about how long it will run. They’ll also keep your engine from overheating by circulating coolant through it. They accomplish this by directing the heat generated by your vehicle’s moving parts. As a result, it is imperative that you get your oil changed on a regular basis.
Since you’re operating a motor vehicle, you should be aware of the critical role that motor oils play. Knowing about the various motor oils and how they differ is also vital. We’ll be focusing on 15w50 and 15w40 motor oils in this article. We’ll compare and contrast these two to gain a better understanding of them. Let’s get this party started!

What’s the Difference Between 15w50 and 15w40 Oils???
Internal combustion engines require lubricant, which is why motor oil is utilized. When your car is running, moving parts in your engine might wear and tear, therefore it’s important to keep your engine’s moving parts lubricated using motor oils. Your piston sealing will also benefit from using motor oil. When it comes to fuel economy, hot weather, and viscosity, let’s take a closer look at 15w50 motor oil vs 15w40 motor oil.
Viscosity
The viscosity of 15w50 motor oil is slightly higher than that of 15w40 oil, making it a lubricant. You may rest easy knowing that this motor oil is capable of lubrication and protection. Known for its long drain intervals, this motor oil is also well regarded. After traveling for about 600 kilometers, it’s time for an oil change. The 15w40 motor oil is therefore appropriate for diesel engines in hotter climates.
Motor oil with a viscosity rating of 15w50 has a higher viscosity rating than that of 15w40. Low-temperature and high-temperature oil viscosity may be the same for both types of oil.
Fuel Economy
For brand-new vehicles in cold climates, 15w40 motor oil is recommended. To get the highest gas mileage, though, stick to the manufacturer’s suggested engine oil. Engines that require a high level of performance should use 15w50 motor oils. You can even use it for racing if your engine is overworked in high-revving and hot conditions. Turbocharged engines can also benefit from this.
There is no significant difference in terms of fuel economy between the two. To reap the benefits of increased fuel efficiency, you must use the proper motor oil.
Hot Weather
You can use 15w40 motor oil in both hot and cold conditions with no problems. When you see “Fifteen” in the motor oil label, it does not suggest that the temperature will be limited to fifteen degrees Fahrenheit at all times. There is a direct correlation between a lower first number and a lower second number. The oil will also be lubricated by more fluid. It’s best to use a heavier oil in the winter. The optimum motor oil to use is 15w40. The 15w50 motor oil, on the other hand, is suitable for usage in both hot and cold conditions.
