Properties of unleaded petrol

[stanier]

I have searched the internet and cannot find information of density, viscosity, vapour pressure and bulk modulus versus temperature (10c to 60C) for unleaded petrol.

Does anyone have a reference or link to hand for this information?

I have come across a value of density of 750kg/m3 at 15C with a "rule of thumb" that it reduces by 0.5% for each 5C change in temperature.

Thanks in anticipation.

A google search for "Gasoline Properties" came up with several links. The first one I opened was Properties of Fuels that has most of what your are asking for (units are a problem, but Uconeer will take care of that in a flash)
