6.0 Powerstroke 5w40 Vs 15w40: Which One to Go With!
What is the difference between the oil from Powerstroke 5w40 and 15w40? The common difference is that 5w40 performs better in comparatively cooler conditions. On the other hand, the 15w40 will be suitable for warmer conditions.
There are also too many circumstances that you need to consider while choosing oil for 6.0 Powerstroke 5w40 vs 15w40. So here, we will try to go through some essential factors like; oil type, temperature tolerance, viscosity, and yes the performance output.
So, without further ado. Let’s jump in!
Debate For 6.0 Powerstroke 5w40 Vs 15w40
| Factors | 5w40 | 15w40 |
| Viscosity | Less viscosity, thinner oil | Comparatively higher viscosity in lower temperature |
| Temperature Tolerance | Suitable for the colder region | Suitable for a relatively warmer environment |
| Best Use | Good heat resistance with an aggressive driving style | Best cranking and cold start |
| Wear & Tear | More wear but economic fuel consumption | Less wear with not good at fuel economy |
| Price | Can be a bit expensive varying brands | Reasonable compared with the 5w-40 |
We hope you start getting comparison facts more clearly here once you have noticed the column. Therefore, we will move to further discussion so that you can get the comparison points even more clearly as we have been discussing finding the best oil for 6.0 Powerstroke.
Note: Here, the number before and after “w” indicates the oil viscosity at a lower and higher temperature.
Viscosity Difference to 5w Vs 15w oil
You should look for the viscosity first when buying oil for your vehicle. There are slight differences between these two oils. For example, with 5w-40, the Kinematic average viscosity is nearly 9.3-12.5mm2/S. On the other hand, you will get 12.5-16.3mm2/S with the 15w-40 oil.
So, when you intend to buy oil for your vehicle, make sure there’s enough thickness in the oil. A more viscous oil increases the performance of the oil. In addition, your vehicle’s engine will run smoothly with a longer velocity weight.
Choosing Oil type From 5w40 & 15w40
The foremost difference here is that the 5w40 fully synthetic oil would be ideal for 6.0 Powerstroke. At the same time, you will find the semi-synthetic type of oil with the 15w40. Therefore, the fully synthetic oil provides your truck’s engine with better performance.
However, for 6.0 Powerstroke engines, fully synthetic can run the engine well. Besides, if you are going for the conventional type, choosing 15 W40 will be ideal.
Temperature Tolerance Of 5w40 and 15w40 Oils
If you ask us the most crucial segment of this discussion, we will talk about this. Therefore, you should keep the temperature circumstances in your mind while buying the oil for your engine or vehicle.
If you have to drive your vehicle in comparatively cooler weather, the 5w-40 will be more suitable for you. Besides, the 15w-40 will be ideal for the warmer winter. Therefore, if you choose the 15w40, you need to change the oil twice. Hence, 15w40 may not be suitable for all temperatures.
Best Use Of Two Oils
If we talk about the usability of these oils, you will be pretty much satisfied. But, you have to choose one at the end of the day. So, let’s make things a bit clear to you.

Price Difference Between 5w40 and 15w40
As shown in the column, you have to pay a bit more if you tend to buy the 5w40 oil for the Powerstroke engine. Therefore, you need to spend less money with the 15w4o oil. So. If you are thinking about the budget more than anything else, the 15w40 will be a better choice for you.
