Re: 2012 mercury 90 4 stroke EFI
Thanks for the replys. I found my answer under the FAQ on Mercury
What alternative/equivalent 4-cycle oils are available when I can't purchase Mercury Marine Precision Lubricants or Quicksilver brands of oil?
If Quicksilver or Mercury Precision Lubricants 4-cycle outboard oil is not available, use a premium quality 4-cycle engine oil, certified to meet or exceed any one or a combination of the following American Petroleum Institute (API) Service Classification SH, SG, SF, CF-4, CE, CD, CDII. Always consult your Operation, Maintenance & Warranty manual for additional information concerning viscosity requirements and temperature ranges.
