What Kind of Engine Oil to Use
Oils recommended for your vehicle can be identified
by looking for the "Starburst" symbol. This symbol
indicates that the oil has been certified by the American
Petroleum Institute (API). Do not use any oil which
does not carry this Starburst symbol.
If you change your own
oil, be sure you use oil that
has the Starburst symbol
on the front of the oil
container. If you have your
oil changed for you, be sure
the oil put into your engine
is American Petroleum
Institute certified for
gasoline engines.
