CHECKING ENGINE OIL (RESERVOIR)
Oil consumption is greatly dependant upon engine speed, with
consumption being highest at wide‑open‑throttle and decreasing
substantially as engine speed is reduced. It is not uncommon 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.
1. With the engine at idle, observe the oil reservoir sight tube.
