What Type Of Oil Does 6.7 Cummins Take?

6.7 Cummins Oil Type


Every vehicle manufacturer has standard recommendations for their vehicles. Cummins strongly recommends using 15W40 grade lubricants. Moreover, many Cummins 6.7 enthusiasts support the 15W40 grade because it operates effectively in hot to medium to mildly low (usually above 50℉). 

On the other hand, if you are driving in regions where temperatures are below 50℉, the 5W40 will be your best pick. This oil type can keep the vehicle healthy in cold weather. 

Oil Specs

According to Cummins Manufacturers, the best engine oils used for Cummins 6.7 should meet these requirements: FCA US Material Standard and MS-11106. Besides, oils with ACEA C3 approval also work well with their engines. 

Alternatively, you can consider oil products that meet API CJ-4/SL or CES-20081 specs. They are acceptable for vehicles with Cummins engines. 

Synthetic or Conventional Oil

From a superior protection standpoint, if you are towing a lot of weight or running in very high/ cold ambient temps 90, 100 F, you should go for synthetic oils.

Also, it’s recommended that you should run synthetic oil for Cummins engines.

Another angle to look at is the oil change interval. Everyone knows synthetic oils do a better job than conventional oil in extending lifespan. The synthetic oils require change every 10,000 to 15,000 miles, while the conventional range is between 10,000 to 15,000 miles.

The last thing to consider is that synthetic oil has less impurities and carbon build-up than conventional oil.
