I don't get this. I've been using those "brand name" repacked mixes for years, but finally got tired of the waste of having to mix a gallon at a time of three different products and throwing much of it away.
I got a syringe device from the local parts store that allows me to mix a pint at time in the ratio I need...but reading through one of my owners manuals, it sez 40 to 1 when it's their pre packaged product, otherwise, 16 to one. The mauls for the other products don't say anything except give the ratio.
I always assumed those pre-mixes were simply two cycle oil in bottles of the right amount to give the desired ratio. Am I wrong about that? Does that mean I can't buy a bult jug of the stuff and measure it out for different ratios? Does that mean if an oil is marked 100:1, I can't measure out enough to give me 50:1???
