Re: Gas oil mixture
No, Boge. Richer would not be better.<br /><br />50:1 is ideal for high speed running. For trolling or idle speeds 100:1 would be better, or even 150:1.<br /><br />Using the same mix at all speeds says that 50:1 is the safe mix.<br /><br />The older engines that called for 24:1 or even 16:1 had sleeve type bearings that required more oil to cushion the bearings. Modern engines have needle and ball bearings that don't need the richer (smokey!) mixture.
