From wiki The conversion factor for aviation gas is .72 so 1lt weighs .72kg

It'll also depend on what type of petrol. Lead-Free, Super, Super-Plus, Normal etc. All of those will have a different weight. And as you can deduce from the Link that was posted above, temperature differences will influence the result too.

Petrol, Vehicle 60 F 737.22 kg per cubic meter

One cubic meter equals 1000 liters

Petrol weight 1Litre = 0.73722kg (at 60 deg F)

I don't know if i need to post a separate question for this but if you reduced the weight of your car by about 20 kilograms because you only filled your petrol tank to a quarter full, how much petrol would you save running the car (on the premise that the car is carrying less weight)? The car in question is a 1.3L nissan micra.

I'm hoping you will say you won't save any petrol consumption!

thanks

That should be a separate question

The conversion factor between weight and volume for petrol depends the temperature (by a significant amount if you are dealing with tanker sized quantities.)
If you reduce the weight of your car by any amount, you will save petrol (but often not much)

How much you save by carrying  less weight depends on how you drive.
Do you do lots of accelerating followed by braking?
Do you do most of your driving at a steady high speed where most of your power is used to overcome wind friction?

andieje,

You currently have nine open questions.  Seven of them EE calls abandoned (i.e., no activity for 21 days).  Some date back to 2007 and 2008.

You can see all your open questions in the Question History section of your profile, and by clicking the "Status" column header you can see all the open questions sorted together.

Please tend to these abandoned questions and any of those nearing abandonment, so as to avoid any further notices from EE.  Thank you.
