I have run these 3 oils:
Maxima Castor 927 50:1
Amsoil Saber Pro 50:1
Opti2 70:1
Castor 927 will spooge all over unless your full throttle the flash point is too high and doesnt burn well in our motors. I am a putt putt rider. 927 is not for me. I had it mixed 50:1 using a #62 jet. Ran well but the spooge was unbearable unless i rode it hard.
Amsoil Saber is good oil..... very concentrated oil in fact. I think if it was possible to run 100:1 safely this might be it. I spoke with Pablo and he recommended running it at 50:1. Thought I would have to jet this mix down like I did with the Castor 927. Jetted correctly the carb wanted a #76 jet which tells me this oil is very thick. I would comfortably run this oil at 70-80:1.... but not 100:1. Sorry guys you cant replace quantity with film strength, mathematically it shouldn't work. As the RPM increases as does the lubrication needed to protect the motor. So going from barely any oil to next to no oil does not sound good to me. More oil never hurt a 2cycle.
Opti2 is awesome oil. The VP of sales for Interlube International (Opti2-4) Paul was at my house and we talked about oil mixes for a long time. He said don't :go leaner than 70:1 in the bike engines. The 1 gallon pouch of oil is a perfect 1.8oz which is a 70:1 mix. To jet this mix correctly the carb likes the #64 jet. No smoke, no spooge! As far as the 100:1 mix goes.... Opti2 site says nothing about it. Again.... no 100:1
I putt around on my bike, i keep the revs low and use my bike to commute to work and back. I can run a lean mix because of that. My bike rarely revs above 2500rpm (24mph in 6th gear with my shift kit) If i revved this thing to its full potential I would mix a heavier oil mix and use Castor 927 but I do not need the extra protection for the high rpm. Take this into consideration when your choosing an oil mix. Choose an appropriate mix for your riding style and make sure to jet it correctly! I always read about what people are mixing whatever oil to and never mention jetting at all.
Hopefully this sheds some light on all the bias people out there. There is no perfect oil mix for all 2 cycle applications. 32:1 50:1 100:1 are all ratios made popular by marketing and magazines. It is nice because it takes the guess work out of what ratio to run. I don't care what oil I use or at what ratio I use it at. It will be jetted correctly to run that ratio and I will probably have success with it.
