So I was getting ready to buy some more 2 cycle oil. I was reading online where someone posted this; 2.6oz = 50:1 ratio 3.2oz = 32:1 ratio Perfect for a two gallon gas can at 32:1 ratio which is where I rung all my stuff and it does not clog up or foul plugs. Works great at that ration and protects better. If you put in a little to much gas your are just moving closer to the 50:1 ratio but not hurting your engine. So the size of each unit is perfect for a two gallon gas can, just poor and go! Is their any truth to this and does it make sense? Or, are you looking for trouble by doing this? I thought it was always best to follow what the operators manual said to do which is 50:1. I ask because I have already had an issue with a brand new back pack blower and a 2 year old trimmer. I had left fuel in both over the winter but it had some stabilizer in it. Apparently that wasn't good enough because the trimmer took about 150 pulls to start and the BP blower kept "coughing" at wide open throttle. Ended up putting in new plugs, fuel filters, dumped old fuel, added that premix echo stuff that's 93 octane, ethanol free, with stabilizer. Ran a can through each unit and they run fine now. Just trying to prevent future issues. Can't afford to spend $8 dollars on 32oz of fuel for everyday use.
