I was thinking about this thread when I was filling up my puch. different premix oils seem to be more efficient at lubing a engine, so do you think they could also change the efficiency as well? Does 30/1, 50/1 or a 100/1 make any difference on how much gas it will take to get to top rpms for your engine and if so then I think there would be a slight difference in total MPG.
I am sure that it is a small variable. Also as certain types of kits like more or less oil it seems like it would be more important to get a efficient cylinder and use the oil best for it but I felt like asking if anyone thought this was valid or if the fumes were getting to me again!
