Checking And Adding Engine Oil - Mercury 135 Verado Manual

IMPORTANT: The use of non-detergent oils, multi-viscosity oils

major brand NMMA FC-W certified oil), synthetic oils, low quality
oils or oils that contain solid additives are not recommended.

Checking and Adding Engine Oil

IMPORTANT: Do not overfill. Tilt outboard out/up past vertical for
approximately one minute to allow trapped oil to drain back to the
oil sump. Tilt outboard to vertical (not tilted) position when checking
engine oil. For accurate readings, check oil only when engine is
cold or after engine has not run for at least an hour.
1. Before starting (cold engine) tilt outboard out/up past vertical
to allow trapped oil to drain back to the oil sump. Allow
outboard to remain tilted for approximately one minute.
2. Tilt outboard to vertical operating position.
3. Remove the top cowl. Refer to Maintenance - Cowl Removal
And Installation.
4. Pull out the dipstick. Wipe the dipstick end with a clean rag or
towel and push it back in all the way.
5. Pull the dipstick back out again and observe the oil level. Oil
should be in the operating range (cross hatched region).
