Re: 24:1 vs 50:1 in 64′ vs 65′ OMC engines

Isn’t XD100 an injector blended synthetic that has a lower viscosity base compared to higher vis oils for non injected engines? I prefer the higher vis base oils in the non injector you mix it 2 cycle engines like the old iron. I use the syn blend TCW3 oils like Mercury Premium Plus and Pennzoil XLF. If I was doing a lot of slow trolling and mid range rpm with occasional short term full tilt running 50:1 would be fine. If I was running at sustained full tilt most of the time I would be using the 24:1. More revs, more oil. "Oil is cheaper than parts" Jerry. Wienandt.
