WSG-1068 GENERAL INFORMATION 

 

Excessive Engine Oil Consumption 

The amount of oil an engine uses will vary with the way 
the equipment is driven in addition to normal engine-to 
engine variation. This is especially true during the first 
340 hours or 16,100 km (10,000 miles) when a new 
engine is being broken in or until certain internal engine 
components become conditioned. Engines used in 
heavy-duty operation may use more oil. The following 
are examples of heavy-duty operation: 

 

severe loading applications 

 

sustained high speed operation 

 
Engines need oil to lubricate the following internal 
components: 

 

cylinder block, cylinder walls 

 

pistons, piston pins and rings 

 

intake and exhaust valve stems 

 

intake and exhaust valve guides 

 

all internal engine components 

 
When the pistons move downward, a thin film of oil is 
left on the cylinder walls. As the engine is operated, 
some oil is also drawn into the combustion chambers 
past the intake and exhaust valve stem seals and 
burned. 
 
The following is a partial list of conditions that can affect 
oil consumption rates: 

 engine 

size 

 

operator driving habits 

 ambient 

temperature 

 

quality and viscosity of the oil 

 
Operating under varying conditions can frequently be 
misleading. An engine that has been run for short hours 
or in below-freezing ambient temperatures may have 
consumed a “normal” amount of oil. However, when 
checking engine oil level, it may measure up to the full 
mark on the oil level dipstick due to dilution 
(condensation and fuel) in the engine crankcase. The 
engine might then be run at high speeds where the 
condensation and fuel boil off. The next time the engine 
oil is checked, it may appear that a liter (quart) of oil was 
used in about 3 to 3-1/2 hours. This perceived 3 to 3-1/ 
2 hours per liter (quart) oil consumption rate causes 
customer concern even though the actual overall oil 
consumption rate is about 50 hours per liter (quart). 
 
Make sure the selected engine oil meets Ford 
specification WSS-M2C153-F and the recommended 
API performance category “SJ” or higher and SAE 
viscosity grade as shown in the equipment Owner’s or 
Operators Engine handbook. It is also important that the 
engine oil is changed at the intervals specified. Refer to 

 
the Engine Operator’s handbook. 
 

Oil Consumption Test 

The following diagnostic procedure is used to determine 
the source of excessive internal oil consumption. 

 
NOTE: 

Oil use is normally greater during the first 300 

hours of service. As hours increase, oil use generally 
decreases. Engines in normal service should get at 
least 31.7 hours per quart (900 miles per quart) after 
300 hours of service. High speeds, heavy loads, high 
ambient temperature and other factors may result in 
greater oil use. 

1.  Determine customer’s engine load habits, such 

as sustained high speed operation, extended 
idle, heavy work loads and other considerations. 

2.  Verify that the engine has no external oil leak as 

 

described under Engine Oil Leaks in the 

 

Diagnosis and Testing portion of this section. 

3.  Verify that the engine has the correct oil level 

 dipstick. 

4.  Verify that the engine is not being run in an 

overfilled condition. Check the oil level at least 
five minutes after a hot shutdown with the 
engine/vehicle parked on a level surface. In no 
case should the level be above the top of the 
cross-hatched area and the letter F in FULL. If 
significantly overfilled, perform steps 5 through 
9. If not proceed to step 10. 

5.  Drain the engine oil, remove and replace the oil 

 

bypass filter and refill with one quart less than 

 

the recommended amount. 

6.  Run the engine for three minutes (10 minutes if 

 

cold), and allow the oil to drain back for at least 

 

five minutes with the engine/vehicle on a level 

 surface. 

7.  Remove oil level dipstick and wipe clean. 

CAUTION: Do not wipe with anything contaminated 
with silicone compounds. 

8.  Reinstall the oil level dipstick, being sure to seat 

it firmly in the oil level indicator tube. Remove 
the oil level dipstick and draw a mark on the 
back (unmarked) surface at the indicated oil 
level. This level should be about the same as 
the ADD mark on the face of the oil level 
dipstick. 

9.  Add one quart of oil. Restart the engine and 

allow to idle for at least two minutes. Shut off 
the engine and allow the oil to drain back for at 
least five minutes. Mark the oil level dipstick, 
using the procedure above. This level may 
range from slightly below the top of the cross-
hatched area to slightly below the letter F in 
FULL. 

10. Record the vehicle mileage or hours.
