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

American Petroleum

gasoline engines.
