Difference Between 5W20 and 10W40

It’s important to change your oil regularly, but it can be hard to know which oil is best for your vehicle. There are many different grades of oil and each one has its own characteristics. This article will explain what makes two popular types of motor oils different from each other: 5W20 and 10W40.

The 5W20 is a lighter weight oil

The 5W20 is a lighter weight oil. The 10W40 is a heavier weight oil. The 5W20 is better for those who want to save money and the 10W40 is better for those who want the best protection possible.

You can save money on the 5W20

5W20 is lighter and less viscous than 10W40. Therefore, it’s a good choice for engines that are not driven often.

It can also be used in extreme temperatures which tend to cause motor oil to break down faster than normal.

The 10W40 is a heavier weight oil

The 10W40 is a heavier weight oil, which means that it has more base stock in it. This base stock helps the oil flow better at low temperatures and protects against wear on your engine by keeping metal parts from touching each other.

This makes the 10W40 ideal for use in cold weather where there are frequent starts and stops or idling periods where the engine doesn’t get up to full operating temperature. In this case, you want an oil with some thickness so that it doesn’t run out of lubrication while you’re driving around town (or sitting at the stoplight).

On the flip side, if you live somewhere warm year round (like Arizona), then using a thinner 5W20 would be better because it will allow air pockets between moving parts so they don’t stick together as often–and when they do stick together due to friction from heat generation during driving conditions (high RPMs), less pressure will be required from them due to reduced viscosity levels provided by lighter weight oils such as those found within 5W20 products available today!

You will use less of the 10w40 when changing your oil

The 5W20 is a lighter weight oil than the 10W40, which means it flows through engine components more easily and quickly. This can be helpful if you have an older car that has been sitting for a while or if you don’t drive very often and want to make sure all of the fluids are circulating properly.

On the other hand, if you’re driving around town every day and driving long distances regularly (more than 50 miles per week), using a heavier weight oil like 10W40 may be better because it can withstand higher temperatures better than lighter weights do.

There are not many differences between the two. The only major difference is that you will get better protection using the 10w40 oil, but this will cost you more money. The 5w20 is a good choice if you are looking to save money.

The 5w20 is thinner and lighter than 10w40, which makes it easier for your car to absorb into its engine. It also allows for quicker heat transfer within your engine because of its low viscosity (thickness). This makes it ideal for engines that are prone to overheating such as those found in sports cars or trucks with large V8 engines because they need less protection from heat compared with sedans/hatchbacks which use smaller motors but tend to run hotter due to their design layout inside the cabin itself where heat builds up quicker due to poor ventilation systems compared with larger vehicles like SUVs & Trucks that do have better ventilation systems built-in from factory level so don’t get as hot after long periods of driving around town all day long!

Takeaway:

The difference between these two oil types is mostly in their viscosity and thickness. 5W20 has a lower viscosity than 10W40, which means it flows more easily when you apply pressure to it. This makes it ideal for use in colder climates where temperatures drop below 50 F (10 C).

The takeaway here is that if your car’s manufacturer recommends using 5W20 instead of 10W40 oil, you should stick with what they say!

The 5W20 and 10W40 are both great oils, but if you are looking to save money then I would recommend using the 5W20. The 10W40 will give your vehicle better protection but it will cost more money. This is because it is heavier than the 5W20 oil which means that less of it will be needed when changing your oil filter every 3000 miles (5000km).
