NOTE
a. After adding oil, leave the engine standing for
one minute and check the oil level.
b. Avoid mixing different brands of oils. In some
cases, they are not compatible with each other
and deteriorate when mixed. Use the same
brand at successive intervals.
c. If the engine has been left standing for a long
period of time, check the oil for level and
contamination before starting the engine. Start
and run the engine for a few minutes. Then stop
the engine and check the oil level again.
