Models: 1994 - 1995 (BR) Ram Truck
NOTE: THIS BULLETIN APPLIES TO VEHICLES WITH CUMMINS DIESEL ENGINES.
On the Ram Truck equipped with the Cummins Diesel Engine, variations in oil level may be observed if the oil check is performed on a warm engine. This condition is due to the slow oil drain back into the oil pan from the in-line injection fuel pump.
Before beginning documentation of a possible oil consumption concern on a 1994 Ram Truck, verify that the dipstick has been updated with P/N 4796874. The correct dipstick, which increases the "SAFE" zone on the oil dipstick to 2 Quarts vs. 1 Quart, will have the Cummins P/N 3928740 stamped on it. After installing the new dipstick, add oil only when the oil level is at or below the "ADD" mark. If the oil level is in the "SAFE" zone, no additional oil is required (Figure 1).
NOTE: OIL LEVEL READINGS ARE MOST ACCURATE WHEN THE OIL LEVEL CHECK IS PERFORMED WHEN THE ENGINE IS COLD AND BEFORE IT IS STARTED, WITH THE VEHICLE ON LEVEL GROUND.
OIL CONSUMPTION SPECIFICATIONS FOR CUMMINS DIESEL ENGINE:
1 Quart per 1000 Miles up to 50,000 Miles
1 Quart per 750 Miles between 50,000 to 70,000 Miles
1 Quart per 500 Miles from 70,000 Miles and Up
Because of the heavy duty construction of the Cummins Diesel Engine, engine run-in is enhanced by loaded operating conditions which allow the engine parts to achieve final finish and fit during the first 6000 miles. Oil consumption may exceed the 1 Quart/1000 Miles specification prior to the first 6000 miles.
1. Change oil and filter (total capacity with the filter is 11 quarts with the new dipstick).
2. Record date, vehicle miles, oil brand and viscosity used. Maintain in vehicle service file for reference.
3. Instruct operator on correct oil check procedure. Instruct the operator to add oil only when the oil level is below the "ADD" mark.
Policy: Reimbursable within the provisions of the warranty.
Time Allowance: Labor Operation No: 09-60-40-92 . . . . . . . . . . . . . . . . . 0.2 Hrs.
Failure Code: P8 - New Part
