& Recommended grade and
viscosity
CAUTION
Use only engine oil with the recom-
mended grade and viscosity.
Refer to "Engine oil" F12-6.
NOTE
Engine oil viscosity (thickness) affects
fuel economy. Oils of lower viscosity
provide better fuel economy. However,
in hot weather, oil of higher viscosity is
required to properly lubricate the en-
gine.
& Synthetic oil
You can use synthetic engine oil that
meets the same requirements given for
conventional engine oil. When using
synthetic oil, you must use oil of the same
classification, viscosity and grade shown
in this Owner's Manual. Refer to "Lubri-
cants" F12-6. Also, you must follow the oil
and filter changing intervals shown in the
maintenance schedule. Refer to "Mainte-
nance schedule" F11-3.
NOTE
Synthetic oil of the grade and viscosity
noted in chapter 12 is the recom-
mended engine oil for optimum engine
performance. Conventional oil may be
used with no detriment to engine dur-
ability or driveability.
