A mechanic may not even be aware that several types of engine oil exist if you change your own oil because most people follow the manufacturer’s recommendations when it comes to engine oil. I’ve put up a comprehensive explanation for individuals who are unsure about the differences between 5w30 and 10w30 motor oils, in particular.
5W30 oil is better suited for places with long and hard winters because it has a higher tolerance for cold. 10W30 is thicker in the cold, whereas both oils are about the same in thickness when it’s warm outside (see chart).
How is Motor Oil Made?
Crude oil is first extracted from the ground and then transported to a refinery, where finished motor oil is made. Sedimentation is used to remove water and big contaminants from the oil. In order to remove even the tiniest particles from crude oil, it is heated repeatedly as it passes through a series of chambers. It is now possible to make conventional motor oil or modern synthetic oil from the oil produced as a result of the process described above.
It’s a common practice to add anti-friction additives to the basic oil in order to reduce friction, keep the mixture linked, and provide superior rust-resistant characteristics. In order to ensure that the oil retains its properties, the oil is tested to the limit. The final step is to package and transport the product to the buyer..
Chemically modified petroleum can be used to make synthetic oil, but it is still more common to start with distilled crude oil. Sophisticated additives and synthesis procedures are involved in the production of synthetic oil, which is a well guarded secret. Regular oil produces the same final result, and there are no discernible distinctions in appearance.
What Does The Engine Oil Do?
Engine oil is similar to blood in the human body in that it is a necessary fluid that serves a variety of important functions within the machine.
Thousands of heat-generating explosions occur per minute in the metal engine block. The engine, like a dry saucepan on the stove, can quickly overheat and lose its hardness if no oil is added. As a result, the cylinder heads and crankshafts deform first before the head gasket ruptures and the engine is effectively out of commission.
Oil is able to withstand extreme temperatures and circulates through the engine’s moving parts. Despite the fact that it cools, its principal function is to lubricate and minimize friction-induced heat. As a result of the decreased friction, the components’ lifespan is prolonged. In the event that contaminants are found in the system, the oil will circulate to the filter and trap them.
Anti-rust additives in engine oil are designed to keep metal components from deteriorating due to corrosion. In a nutshell, each car with an internal combustion engine needs motor oil.
Engine Oil Grades
Engine oil bottles have been marked in a variety of ways.
“number” with “number” The grade of engine oil is denoted by the following markings:
The scale was made by SAE (Society of Automotive Engineers) to help owners find the right oil type for their conditions.
The significance of oil grades
Temperatures as low as 40°C can be maintained with a 0W winter motor oil. At 30°c, the 10W grade can function well, but the 20W grade cannot.
Temperatures as high as 50°c can be handled by motor oil with a 50 warm rating. The 40 grade can operate at temperatures as high as 40°c, however the 30 grade should not exceed 35°c.
Difference between 5W30 vs 10W30
You can determine the difference between 5W30 and 10W30 now that we’ve covered engine oil grades. It’s okay to run at 35°c in the winter with 5W30 oil and not at 30°c with 10W30. Having the same summer rating of 30, both types of oil are suitable for use in vehicles operating in temperatures of up to 35°c.
5W30, on the other hand, covers a larger range of temperatures, therefore it’s excellent on paper. If we were to choose oil based on this criterion, the best choice would be 0W40, which has better temperature tolerances on both ends of the spectrum. That different types of oils exist and that you should not alter your oil type without first conducting some research is evident.

There isn’t much of a difference between 5W30 and 10W30 because both oils can withstand extremely low temperatures. There are two types of oil to choose from: 5W30 for colder climates, and 10W30 for hotter climates or for older cars.

How to Choose Engine Oil
The first thing to keep in mind is the type of oil advised by the vehicle’s manufacturer. Even though modern cars can go almost anywhere, the environment and temperature in Alaska and Texas are vastly different. As a result, the makers always provide a list of oil types that can be used in a wide range of temperatures.
The engine’s construction is also a factor. It doesn’t matter if the summer temperature doesn’t get above 30°C, diesel engines require heavier oil and 5W40. Some of the latest gasoline engines require 0W-20, which is the thinnest oil on the market.
You still have plenty of possibilities, even if the manufacturer restricts your choices. Looking at the forecast for the warmest and coldest months of the year and seeing how far temperatures go will help you decide what oil grade you need. If the temperature is consistently above the rating of your oil, you should replace the oil type by 5%. Exceptional hot or cold days do not need changing the oil type.
I’ll compile a list of the best oil makers so that you may shop with confidence.

FAQs
Can you put 10w30 in a 5w30 engine?
Change to 10w30 if the manufacturer allows it. If it says 5w30 can be used, then go ahead and do it. As a rule of thumb, if your car is a few decades old, you should use heavier oil.
Which oil is thicker 5w30 or 10w30?
Temperature ratings of 30 indicate that both oils are thick in the summer. It’s also thicker in the winter, so it’s not ideal for colder areas.
Summary
Switching from 10w30 to 5w30 shouldn’t be a problem because the variations between the two are so little. Still, it’s a good idea to check with your engine’s manufacturer to make sure you’re using the correct oil for your vehicle. Insufficient lubrication of the engine is never a good thing, and using the wrong oil might contribute to it.
