If you are often involved in the activity of changing your vehicle’s motor oil, then there might have been many occasions where you have wondered if you could use 10w30 oil instead of the usual 5w30 oil you use to power the engine.

Well, as it turns out, you are not alone. And there are many who often find themselves tangled in the same dilemma as you. Well, don’t worry as we have got you covered and this is just the article to help you make your decision.

Benefits of Using 5w30

The oil is designed in a way that the fuel consumption is also minimized, increasing the fuel economy, which is due to the lubrication provided by the oil to the engine.

Last but not least, there are many benefits offered to the gasoline-powered engines by the 5w30 motor oil, amongst which the most important ones are their effectiveness during the cold starts and operation of the engine in cold weather conditions.

These light-duty gasoline-based engines do not have very high power, especially during cold start-ups, which is where the 5w30 kicks in.

Hence, 5w30 is pretty much the best option for the engine, which are low duty and have to be operated under cold climate conditions.

10w30 VS 5w30

As we have already seen the meaning of the numbers, you probably have a rough sketch in your mind by now about the major differences in both these oils by now.

Both the above types basically have the same viscosity, which is the thickness level once they reach normal operating conditions.

However, before reaching that point, a 10w30 will move slower as compared to the 5w30 and reach the components slower, which can be problematic, especially in cold start-ups.

As anticipated, it is quite recommendable to choose 5w30 if you live in a cold region or it gets really cold around your area in winter.

Using 10w30 in such situations could result in really hard conditions when starting up the engine and could even cause unwanted damage to the vehicle’s engine.

But, 5w30 would work fine even in quite cold conditions as it would be easier to flow at a lower temperature.

However, it’s not just about getting the oil that has the most viscosity, or as people say, thickness. The requirements are different for each kind of vehicle, and not every vehicle needs the same weight of oil to operate normally when compared to the other.

So, always refer to the manual of the vehicle and choose the oil viscosity accordingly without jumping straight to the thickest oil out there.

Using some oil that is too much thick for the engine can result in increased drag as a result of increased temperature. Moreover, fuel economy also experiences a setback.

The same is the case with using oil with too low viscosity that it flies off within the internal components causing damage to the engine and decreased fuel economy as well.

So, always consult a mechanic while choosing the best oil for your vehicle as they give an estimate of the range of oils you can use for your engine, or you can refer to the manual.

How Is Upgrading Oil Beneficial In High Mileage Vehicles?

If someone is very much comfortable with using oils with more viscosity than what’s recommended, then they definitely are the owners of high mileage vehicles.

What happens is when a vehicle grows oil, the oil passages through which the oil travels to the engine wear down, causing a reduced pressure applied from the oil to the engine.

Now, this gap somehow needs to be filled to get your vehicle back to the usual performance, or it would obviously start getting behind.

What these owners do is that they compensate this reduced pressure due to the pipes by using a thicker oil than what they used to be.

But mind you, the number of the name they increased here is the number at the end, indicating the thickness once the engine reaches the high working temperatures.

So, for instance, they could start using 10w40 instead of the usual 10w30 they used to use. This way, they get what they want, enough pressure from the oil even by having worn out passage pipes.

So, you could also consider using this trick to get an increased oil pressure if your vehicle has done a lot of mileage, and now the pressure being applied by the oil is not enough anymore.

Final Thoughts

As we saw during the course of the article, it is not such a big issue to use 10w30 instead of 5w30, depending upon your need. There are many overlapping factors between the two oils and many similarities, with many of the features being common to both kinds of oils.

So, depending on your need, feel free to use the right kind of oil for your vehicle without worrying about the side effects as long as the viscosity of the oil is within the range prescribed by the manual of your vehicle.
