Slant would probably still burn that kerosene at 7.5:1. But a lawnmower is about all its good for and that is a stretch. My finnicky lawnmower wont even start unless its drained before I put it up and then it gets fresh gas out of a screw top fuel can. This new **** doesnt last long in the tank before it starts to turn to jello in the carb jet. It may be a good thing that the tank was almost full as it wont rust where its submerged.
