There is something seriously flawed with this chart. To start with they are
changing ooil at 50 hours. My merc says 100 hours.
The other thing is are they really saying a 200 hp 2s engine can run 100 hours
on 20 quarts of oil? That's 5 gallons and even at 100:1 that is only 5 gallons
of fuel per hour. Are these hours being put on at idle speed? I know a lot of
guys with 200s and they would kill to get 5 GPH at any decent cruise speed. I
also think these motors use more like 50:1 at high speed. The 100:1 is at idle.
I have a neighbor with an Optimax. I will ask him how long a gallon of oil
lasts him. I know I gave him 2 gallons when I bought my 4 stroke and he didn't
act like it was a lifetime supply.

My Contender, at cruise with FICHT 225s, uses about 8 Gph per engine
averaged after the trip which accounts for idle time. I rarely run
WOT. At idle or trolling speeds, 5 Gph isn't unheard of.

My Ranger which has a FICHT 200 gets 5 Gph all round - it has never
varied from day one.
