What kind of oil does a Ram 3500 diesel take?
Valvoline Premium Extreme Full Synthetic Engine Oil 5W-40 Another product recommended by Cummins to use on their engine. This 5W-40 viscosity graded oil is an upgrade from the conventional 15W-40.
What oil does 5.9 Cummins take?
2003 – 2007 5.9L Cummins ISB Oil Viscosity Chart (24 valve, common rail)
| Ambient Temperature Range | Recommended Oil Viscosity |
|---|---|
| Greater than 0° F | SAE 15W-40 |
| All temperatures | SAE 5W-40 full synthetic |
What oil does a 12v Cummins take?
1989 – 1998 Dodge Ram, Cummins 12v Fluid Specs & Capacities

|---|---|
| 5W-30 (ambient temperature < 0° F w/o block heater) | |
| Engine coolant: | 50/50 ethylene glycol coolant, distilled water |
| Automatic transmission fluid: | 47RH/47RE 4 spd |

How often should you change the oil in a Cummins diesel engine?
Straight out of the gate we recommend 6000 km (3700 mile) oil changes if you are running conventional oil 15W/40. This should be a safe interval for city driving, stop and go driving, and idling.
Can I switching from 15W40 to 5W40?
5W-40 will span the range covered by both 5W-30 and 15W-40. 5W40 oil will remain suitably fluid (i.e. suitably low viscosity) at lower temperatures than 15W40 oil. Both will operate reliably up to the same outside high temperature.
What oil is thicker 5W40 or 15W40?
Almost all engine wear occurs when the engine has just started and the oil is still too thick to flow at a rate the engine requires. Viscosity, at low temperatures the difference is the 15w 40 is thicker than 5w 40 at room temperature. Heat them to 140 Fahrenheit and they will have about the same viscosity.
Is 5W40 good for summer?
Be happy; 5W40 is great for summer with the added bennie of great cold start specs. As to interval, you can safely go longer but how much longer will depend on the soot load and fuel dilution. My oil analysis has shown it takes about 5.5K miles for the soot to get up to 0.4-0.6 percent.
Will 5w40 hurt a 5w30 engine?
If you are racking your brain to choose between 5w30 and 5w40, we recommend you go with 5w30. However, if it is too expensive or not available for use, you can always go with the 5w40, which is just as good and will not cause any damage to the engine parts.
Is 5w 30 better than 5w40?
In practice, this means that each oil is just as viscous at lower temperatures and will remain viscous at -30°C, however 5w40 oil outperforms 5w30 oils at higher temperatures, being effective up to ambient temperatures of 50°C, as opposed to 30°C.
Which oil is thicker 5w30 or 5w40?
Viscosity The working viscosity of 5w30 is basically from 9.3 to 12.5mm2/s whereas the operating viscosity of 5w40 is 12.5 to 16.3mm2/s. That means 5w40 has larger viscosity than 5w30. So, 5w30 is better than 5w40.
Can you switch from 5w30 to 5w40?
‘ Yes, you can depend on the temperature range. 5W30 and 5W40 oils are mainly used for winter or cold temperature; still, they have thinner quality for the hot temperatures, like 5W30 can be used from -30° to 30° temperature range and 5W40 can be used from -40° to 40° capacity.
What happens if I put 5w30 instead of 5w40?
What would happen if I use 5w30 oil instead of 5w40 in my car engine? – Quora. , Over 200,000 miles on 2-wheels and 2 crashes. So long as the oil pump can produce enough pressure to get the oil flowing into all the important areas properly, there should be no problem.
Can I use 10w 40 instead of 5w40?
10w40 is thicker than 5w40, ONLY when cold. At operating temperature it is exactly the same. Multi-viscosity oils with a lower W number are specifically designed to flow better, and thus lubricate better, at very low temperatures. There is no need to use a 5w-40 if the vehicle only requires 10w-40.
Which is thicker 5w40 or 10w40?
The 5W40 is thinner than the 10W40 at lower temperatures. But when the temperature is higher, both motor oils similarly perform their intended functions (using the same viscosity). On the other hand, the 10W40 motor oils are thicker than the 5W40 oils for good reasons.
