The link I shared above was one additional finding.Could be wrong, but as a retired mechanic with a ton of racing experience this is what I would expect.
Gasoline will produce more power per ounce than oil so a leaner mix will produce quicker cut times. In addition gasoline undergoes a lot more evaporation than oil so (assuming there is enough oil to prevent friction damage at the skirt) a cooling effect will also be seen. That said that does not mean that a 40/1 mix does not extend wear it just means that the friction produced by this small amount of wear is less than the power increase seen with the extra fuel available at 50/1.
Just in case someone chimes in that the last few years F1 cars were being built to intentionally use oil to gain power....this was a different deal. It was due to fuel usage restrictions in F1 (the amount of fuel available is limited) so even though the oil (from the dry sump tank) had less power than gasoline it was still additional power that was not calculated by the FIA as fuel.
I only get more than a gallon if I know I’m going to use more than a gallon in one day. That translates into almost never.And also, do y'all mix a few gallons at a time, or what? After you mix it, will the oil disperse, or does it require shaking the container every time you go to top off the tank?
I burn the 89 e free. Saws run better than high octane with ethanolThanks, guys.
Got some Schaeffer's on the way. Going to try and mix me up some 40:1. Would anyone recommend a higher oil ratio, like 32:1?
Also, a local place 2 min from me has 89 octane ethanol-free. Is that rating too low? I know crap about these engines compared to just about any of y'all, but the stuff I usually run - Stihl Motomix - is 93 octane.
