Hi all, I am reconditioning an old Mercury 650 (1975 model)
Does anyone have the same engine. What is the proper fuel-to-oil
mixture?
Thanks
Quicksilver Formula 50 or 50-D, mixed 50:1 w/ 86 octane minimum leaded,
low lead, or unleaded. TC-W, TC-W II/2 or TC-W III/3 can be
substituted. Use 25:1 during break-in(two + hrs. at no more than
2500-3500 rpm). No sustained WOT for the 1st 10 hrs.
