How many quarts of oil does a 2002 Dodge Cummins take?
11 quarts
What oil does a 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 |
Can you put 15W40 in a 5w40 engine?
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.
What happens if you use 15W40 instead of 5w30?
Using 15w40 instead of 5w30 will increase your fuel consumption because of more load on your engine’s crank. No, head gaskets have nothing to do with the oil. Head gaskets blow either due to defective design or overheating.
Is 5W30 better than 15W40?
Probably not. 15w40 is usually used in diesel engines and has a much different additives profile. 5w30 is usually used in gasoline engines. Diesel oil is designed with high antiwear additives such a ZDDP.
Can I mix 5W30 with 15W40?
You aren’t supposed to mix weights. If you don’t have anything else to replace 5W30, use only 5W30, according to the owners manual. If you are unsure about mixing different weights, check out Bob Is the Oil Guy.
Can I use 10W 30 instead of 15w40?
Since 10W-30 is thinner than 15W-40, 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 10W-30 to protect as well and last as long as 15W-40.
Can I use 20w50 instead of 15W40?
20W-50 motor oil is for vehicles with gasoline engines. 15W-40 oil is for diesel applications. The difference between the two grades are just the specifications and for all practical purposes, in older vehicles without variable valve timing, the two grades of oil are interchangeable.
Is 10W-30 Good for diesel engines?
It is recommended for use in a wide range of heavy-duty applications and operating environments found on-and off-highway, including engines operating under heavy loads. Fully backward compatible, Mobil Delvac Extreme 10W-30 engine oil delivers exceptional performance in both newer and older heavy-duty engines.
Is 10W-30 Good for diesel?
In a commercial fleet with good fuel economy, going to a 10W-30 CK oil is a good move for fuel economy. If you’re more concerned about your engine durability, and you run engines to the very end of their useful life, and a couple percentage points of fuel economy is not that attractive, then you may choose 15W-40.
Is 5w30 OK for diesel?
The ’30’ or ’40’ refers to the oil flow at higher engine temperatures. ’30’ is often for newer petrol engines, while ’40’ is often for older or diesel engines. 5W-30 and 5W-40 oils are compatible with some models of common cars, like the Ford Focus, Ford Ka, Honda Civic and VW Golf.
