We can even enjoy some old fashioned engineering fun and re-calculate these units into something else.

Since gasoline's specific weight is about 0.7 grams/milliliter and there are 3785 milliliters per gallon, this translates into 2649 grams per gallon of gasoline.
Therefore 0.136 grams per second translates into 0.00005134 gallons per second, and 0.167 translates into 0.00006304 gallons per second.
Or put another way 19,477 seconds to consume one gallon of gas in the former case, and 15,862 seconds in the latter.

You may want to check my calculations, they were done in a hurry.

The true smart man is the one who appears to be dumb in front of dumb man who appears to be smart.
