What is 10W 30 oil?
The 10W30 designation on engine oil means that the viscosity of the oil is rated at 10W when an engine is cold, and 30 when the engine is hot. This is different than an oil labelled 5W30, which has a thinner viscosity when the engine is cold at 5W.

Can I use 15w40 instead of 5w40?
15w40 can be used in the temperature range of -20 °C or -4 °F and +40 °C or 104 °F, on the other hand, 5w40 is used between -30 °C or -22 °F and +40 °C or 104 °F. So, we can say that 15w40 is better in a warmer environment and 5w40 does a better job in a colder climate.
Can I use 15w40 instead of 10w30?
Will 15w40 Work For 10w30? The traditional 15W-40 oil is being replaced by the 10W-30 oil for heavy-duty applications. Fuel economy and power over can be improved by using a 15W-40 engine if it is designed and manufactured to use a 10W-30 engine.

5-40 is thinner in the cold. there is no need to run 5-40, however those who live in cold climates that frequently get below 0 may experience easier starting, less wear and tear on the engine, and quicker warm up times with 5-40.
Why does Cummins recommend Valvoline?
Torkelson explained that Valvoline “had to balance the capability to perform in a higher-temperature engine like a natural gas engine while having the capability to function in a lower temperature engine as a diesel engine – although as diesel engines have evolved, they're getting hotter and hotter.”
What oil do you use in a diesel engine?
Since these engines combust at much higher compression ratio than gasoline engines, the oil used in the motor has to be able to withstand tremendous forces, usually of 40,000 to 50,000 psi. Most newer diesel engines will recommend 15W-40 because it is heavier and thicker.
What is Cummins X15?

Which is better 10w30 or 15W40?
Because 10W-30 is thinner than 15W-40 oil, its film strength can be weaker and it can be more prone to oxidation. Therefore, high quality additives are needed to compensate for those weaknesses in order for a 10W-30 engine oil to protect as well and last as long as a 15W-40.
Should I use 10w30 or 10W40?
There's not much difference between 10W-30 and 10W-40 motor oil. What sets them apart has more to do with temperature fluctuations and engine load. For moderate weather, either engine oil grades should work fine. Your choices will become more critical when you start getting into high-heat situations.
Which is better 10W40 or 15W40?
Motor oil grade represents the weight of the oil when cold, as well as at operating temperatures. Viscosity or thickness of the oil increases with rise in temperature. A 10W40 oil will be thicker in the cold than 15W40 oil, but they will have the same viscosities at higher temperatures.
When did Cummins ISX start using def?
