Does diesel gas weigh more then the general gas we use every day?

Question

I just want to know how and why is diesel gas weigh less then general gas?

Answer 1

1 pound of diesel weighs less than 2 pounds of gasoline, but 2 pounds of diesel weigh more than 1 pound of gasoline. It is that simple, really

Answer 2

no such thing as "diesel gas". I think you mean diesel fuel, which does weigh more than gasoline.

Answer 3

Diesel's density is actually a bit less than gasoline. The density of petroleum diesel is about 0.85 kg/l (7.09 lbs/gallon) whereas petrol (gasoline) has a density of about 0.72 kg/l (6.01 lbs/gallon), about 15% less.

Diesel also has a higher energy density.

Don't let the first poster annoy you.  When I step on the accelerator in my diesel car, I think it's fine to say "gas pedal" as much as "diesel pedal".  I also say "I need gas" when I actually need diesel.

Answer 4

As 'Gas' refers to 'Gasoline', Diesel can't be called 'Gas'.

However, I understand your question regarding the difference in their Densities.

Gasoline has a Density of around 0.750 kg/L, and Diesel fuel is around 0.860 kg/L making it 'Heavier' than the Gas generally used every day.

(For your interest, both are 'Lighter' than water which has a density of 1.0kg/L).

And, for the thumbs downer, DON'T try to tell me this is an incorrect answer. I've been working in the related Industry in Supervisory Positions, covering just about every aspect of Oil and Gas Operations probably since before you were born.

Answer 5

Diesel weighs about 7 lb/gal. Gasoline weighs about 6 lb/gal, though both vary from winter to summer and with additives. Thus, diesel is more dense than gasoline, not less. Gas has been getting denser over the years, as the composition changes. Both are composed of hydrocarbons plus additives. Hydrocarbons are a chain of carbon atoms with 2 hydrogen atoms per carbon atom. The end atoms have 3 hydrogens instead of 2.  Gasoline uses chains with 5 to about 12 carbons;

diesel hydrocarbon molecules (chains) use about C10 to about C15 carbons.

The longer chains fit together using a little less room, and have more carbons/fewer hydrogens on the average. Carbon is heavier than hydrogen. Thus, since the gasoline hydrocarbons are less dense, gas is about 18% less dense than diesel.  Energy is almost the same per pound, but diesel has about 18% more energy per gallon.
