ENGINE OIL RECOMMENDATIONS
We recommend the use of Mercury or Quicksilver SAE 10W30 multiviscosity
4stroke outboard oil for general, alltemperature use. If SAE 25W40
multiviscosity oil is preferred, (see chart above) use Mercury MerCruiser 4cycle
engine oil or Quicksilver sterndrive & inboard 4cycle engine oil. Never use
4cycle engine oil that is not certified to meet or exceed any one or combination
of the following American Petroleum Institute (API) Service Classification SH, SG,
SF, CF4, CE, CD, CDII. Severe engine damage may result from use of an inferior
oil.
RECOMMENDED SAE VISCOSITY FOR ENGINE OIL
SAE 10W-30 viscosity oil is recommended for use in all temperatures.
SAE 25W-40 viscosity oil may be used at temperatures above 40° F (4° C).

CHECKING AND ADDING ENGINE OIL
IMPORTANT: Do not overfill. Be sure that the outboard is upright (not tilted)
when checking oil.
1 Turn the engine off. Have the outboard in a level operating position. Remove
the top cowl.
2 Flip the handle up and pull out the dipstick (a). Wipe it with a clean rag or towel
and push it back in all-the-way.
3 Pull the dipstick back out again and observe the oil level. If the oil level is low,
remove the oil filler cap (b) and fill to (but not over) the upper oil level with the
recommended oil.
IMPORTANT: Inspect oil for signs of contamination. Oil contaminated with
water will have a milky color to it; oil contaminated with fuel will smell
strongly of fuel. If contaminated oil is noticed, have the engine checked by
your dealer.
4 Push the dipstick back in all the way, then flip the handle down to lock the
dipstick in place. Reinstall the oil filler cap and hand tighten securely.
