Pedantry is fact checking a comment, figuring out it would actually take around a cup (or 1/4 liter) of gasoline, then figuring out how to convert that to drops and pointing out it would actually take close to 4,700 drops, not just a few.
Here let’s pull a number out of our butts, let’s say a drop is a sphere with a diameter of 5mm, so the radius is 0.25cm. Volume is 4/3 pi r^3 which comes out to 0.065 cm^3/ drop.
0.294/0.065 gives 4.5 drops.
So you’d need 5 drops of gasoline to get your days worth of energy.
Seems we’re off by a factor of a thousand. Most likely you doubled up on 1Calorie = 1000 calories. (Damnit food industry, what the hell?!?) 1kcal is already converted to the base calorie, as opposed to 1kCal.

Smart-assery is replying how it can still be consumed as just a single, very large drop.
Smart-assery is replying that gasoline doesn’t have enough surface tension to form such a large drop.
Lemmy-ing is recreating a typical Reddit thread but making sure every comment points out that they’re self-aware.
Hmmm let’s see, you need roughly 2.39kcal or 10kJ of fuel a day.
Gasoline has an energy density of 45 MJ/kg.

Sciencing those together means you need 0.00022 kg or 0.22g of gasoline a day
Gasoline has a mass density of 0.7475 g/cm^3, more sciencing means you need 0.294 cm^3 of gasoline by volume.
