Maintenance and service/Engine oil

. For models except STI, be careful
not to touch the engine oil filter
when removing the oil filler cap.
Doing so may result in a burn, a
pinched finger, or may cause
some other injury.
. Use only engine oil with the
recommended grade and viscosity.
. Be careful not to spill engine oil
when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. If
engine oil gets on the exhaust
pipe, be sure to wipe it off.
To add engine oil, remove the engine oil
filler cap and slowly pour engine oil
through the filler neck. After pouring oil
into the engine, you must use the level
gauge to confirm that the oil level is
correct.
For models STI, just after driving or while
the engine is warm, the engine oil level
reading may be in a range between the
upper level and the notch mark. This is
caused by thermal expansion of the
engine oil.

NOTE
To prevent overfilling the engine oil, do
not add any additional oil above the
upper level when the engine is cold.
