Checking Fluid Levels
CHECKING CRANKCASE OIL
IMPORTANT: Check the engine crankcase oil at the intervals
specified in the Maintenance Chart.
NOTE: Oil consumption is greatly dependant on engine speed.
Consumption is highest at wide‑open‑throttle and decreases
substantially as engine speed is reduced. It is common for big
block, high‑performance engines to use up to one quart of oil in
one to five hours, if the engine is operated continuously at the
upper end of the RPM range.
