Engine Oil Consumption
All engines consume some oil. The consumption rate
depends on loading, design of key parts and engine
condition. Since fuel consumption is an indicator of
operating power levels, fuel used versus oil consumed
is a critical factor in analyzing oil consumption. Oil
consumption should be measured over a 100-hour
period.
Long-term oil consumption (three oil drain intervals
after the engine is broken in) with consumption rates
poorer than 400:1 (100 gallons of fuel and 1 quart of
oil) indicates a need to monitor/investigate. Suggested
steps would be:
•
Check for signs of ingested dust or perform an
OILSCAN
test to check for silicon.
•
Check for proper crankcase oil fill level.
•
Remove head and inspect for glazed or worn liners.
•
Inspect pistons for carbon deposits in the ring land
grooves.
•
Measure valve stem OD and valve guide ID to
determine clearance.
NOTE: Ring gap alignment does not identify the leak
source.
Intake valves do not have valve stem seals,
and some oil deposits on the valve stem tulip
are normal.
When changing to a premium oil such as
TORQ-GARD SUPREME
PLUS-50
, little oil
consumption change is expected, although a small
percentage of engines may experience a noticeable
change in consumption rates. This may be due to the
following:
•
The previous oil may have left deposits on internal
components. Use of PLUS-50
oil will cause
different chemical reactions in those deposits. The
time required for the engine to regain the previous
oil consumption rate will vary from one to three
normal drain intervals.
•
TORQ-GARD SUPREME
PLUS-50
contains a
high-performance anti-oxidant along with other
additives resulting in the oil remaining in the
specified viscosity grade throughout the
recommended drain interval. API oil grades CD, CE,
and CF-4 universal engine oils do not provide this
oxidation resistance which results in more rapid
thickening. Increased oil viscosity can reduce oil
consumption.
