Is 5W30 Good for Summer? (Yes or No)

Is 5W30 Good for Summer

The 5W30 is an engine oil brand for cars and automobiles and it’s one of the most commonly used engine oil, this is because it is suitable and can be used by a wide variety of vehicles, it doesn’t just work for some selected few.

The 5W30 can be used as a vehicle that uses petrol and diesel. Hence, the saying it’s used by a wide variety of vehicles and it ranges from viscosity as low as 5 and higher than 30. The term 5W30 means the following;

  • 5 – refers to the low viscosity of 5 at low temperature
  • W – Meaning Winter
  • 30 –  refers to high viscosity at high temperature when the engine is in motion

The 5W30 can perform well both in the summer and winter periods notwithstanding the ‘’W’’ meaning Winter as a name written on the brand. It’s a multi-graded oil and would function effectively in low winter temperatures and high summer temperatures.

What are the Components of 5W30 Oil?

The components of the 5W30 that make it a multi-graded oil and function in any weather condition whether winter or summer includes the following:

  • The 5W30 comprises a synthetic base such as the PAO 4-8
  • High-performance additive package for cars
  • 5W30 comprises an anti-foam agent
  • 5W30 also comprises of viscosity improver used for adjusting the viscosity
  • 5W30 also compromises a sufficient quantity of dye to produce more oil

Can I use 5W30 in the Summer?

The 5W30 is a multi-graded oil meaning, it can function both in winter and summer and this is because of the viscosity range of the oil from as low as 5 during winter or low temperature to as high as 30 during Summer or high temperature. It is also more fuel-efficient for cars. Hence, the 5W30 can be used in summer as well as winter.

Is 5W30 Good for Summer?

Yes!! The 5W30 is good for summer because of its viscosity as high as 30, which can be used to sustain the vehicle during summer.

The 5W30 is a good engine oil brand for summer and winter alike and it’s not restricted to cars with petrol but also for cars that are diesel-powered.

For individuals that are skeptical about the use of 5W30 during summer, it’s a good and sustainable brand for winter and summer alike.

Pros of Using 5W30 in the Summer

The 5W30 aside from the fact that it can be used in the summer, also has a number of advantages if used by cars during summer and a few of them would be highlighted below:

  • It is a multi-graded and viscous oil meaning that it acts differently under summer and winter conditions
  • It acts thicker when the engine is hot or in a summer condition
  • Its dual performance for summer and winter condition
  • They are highly versatile and are commonly used in varieties of engine
  • They can be used by vehicles that use petrol as same as diesel-powered vehicles
  • It allows you to use the same oil throughout the year, not letting you have to change the oil when weather condition changes
  • It gives protection to your gear due to its thickness during summer

Is 5W30 or 5W40 Better in Summer?

Both the 5W30 and 5W40 are great oils and can be best used for summer, they both have synthetic bases and have the right combination of viscosity that would enable cars to perform effectively with them during summer.

The 5W40 contains reduced engine wear due to the presence of the synthetic base, it also helps to reduce friction, and it also has improved antioxidant properties. But, the 5W40 is better than the 5W30 during summer due to its high viscosity.

There are few major differences between the 5W30 and the 5W40

  • The 5w40 has a high viscosity during summer than the 5W30, but they can both be used during summer
  • The temperature range varies for each, the temperature of the 5W30 ranges from -25to 25 degrees Celsius, and the 5W40 temperature ranges from -25 to 35 degrees Celsius
  • The 5W40 provides higher pressure than the 5W30
  • The 5W40 is thicker than the 5W30
  • The 5W30 is more versatile unlike the 5W40 which is less common
  • The 5W40 is cheaper compared to the 5W30

Is 5W40 thicker than 5W30?

The 5W30 has a viscosity as low as 5 and higher than 30, while the 5W40 has a viscosity as low as 5 and higher than 35, which indicates that the 5W430 is thicker due to its low viscosity than the 5W40.

The 5W30 is suitable due to its thickness in all temperatures while the 5W40 is not suitable in all temperatures. The fact that some oil is thicker doesn’t mean you should drive your car with water in the gas tank or oil. It is very dangerous.

What Engine Oil is Best for Summer?

The engine oil best for summer is engine oil that is slightly thicker and can withstand the temperature. The 10W30 has thicker viscosity meaning that it’s preferable to use during summer than the 5W30 in summer and if possible there’s an engine oil with greater thickness and viscosity it would be best used for cars during summer.

Hence, the thickness and degree of viscosity are key factors one should consider when using engine oil during summer because it would help the vehicle and reduce lagging in vehicles.

But the leverage the 5W30 has is that it’s a multi-graded oil and is dual-purpose, meaning it can be used during summer and winter alike and that shows that you don’t have to change the oil in the vehicle as a result of a change in weather condition and it’s sustainable for a year stretch.

So notwithstanding how functional the 5W40 and 10W30 can be, the 5W30 is on leverage because it can be used by different vehicles that use petrol or diesel and there’s no need for a change of oil as a result of weather conditions and any other condition alike.


The 5W30 was shown to be at an edge over other brands of engine oil because of its dual function and it was able to function in any weather condition whether it be a petrol or diesel engine vehicle it would function effectively.

It also gives your vehicle gear maximum protection due to its thickness and high viscosity which would protect your vehicle’s gear during summer.
