There is something seriously flawed with this chart. To start with they are
changing ooil at 50 hours. My merc says 100 hours.

I didnt know that .. that would indeed offset this a little ...

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

The 2 stroke is posted at 4250 RPM and my 200 HP 2 stroke gets 5.8 MPG
at cruise. The oils is based on that and an average of 65:1

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 get 4.8 US gallon per hour at cruise at 28 MPH ... 200 2 stroke HP !

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.

Mine uses .3l per hour at cruise ... whu knows how many gallosn this
are.

Dont forget this chart isnt religion, I just put it together for
myself to see how bad the oil use really is.. Take it for that and not
more.
