I’m not an expert in the chemistry at all but how does the 2-cycle oil added to the fuel contribute to carbon density of the fuel?

- margalabargala 3y agoIt's denser than octane but doesn't meaningfully close the gap. To drive 1100 miles, the commenter above gave an extremely generous 25 gallons of gas (likely closer to 40 for a non-Prius). One gallon of gas produces about 20 pounds of CO2, which is about 73% oxygen (from the atmosphere) by weight. The remaining 27% of the weight comes from carbon. So, one gallon of gasoline provides 20*0.27=5.4lbs of carbon to the CO2 produced. Multiply by 25, and you're looking at over 135lbs of carbon alone coming from your source when 25 gallons of gas are burned. Considering that the amount of weight carried around by the user of a leaf blower is on the low tens of pounds, and not hundreds, it seems ludicrous to presume that a leaf blower produces anywhere near the amount of CO2 in an hour as does a car driving 1100 miles.

- Gordonjcp 3y agoIt basically doesn't. Even without the oil - 2-stroke engines will run on straight petrol, albeit briefly - they still emit an obscene amount of unburnt fuel.
