You should change the oil as soon as you can.
See Engine Oil (Gasoline Engine) on page 5-15.
In addition to the engine oil life system monitoring
the oil life, additional maintenance is recommended
in the Maintenance Schedule in this manual.
See Scheduled Maintenance (Gasoline Engine) on
page 6-4 for more information.
Remember, you must reset the OIL LIFE display
yourself after each oil change. It will not reset itself.
Also, be careful not to reset the OIL LIFE display
accidentally at any time other than when the oil has just
been changed. It cannot be reset accurately until the
next oil change. To reset the engine oil life system,
see Engine Oil Life System on page 5-18.
