The Grand Fuels & Oils Weight Page

[Zipper730]

This is something that usually is found piecemeal all over the place, so I figure it's a good idea to just have one big page that's got all the pounds per gallon data.

So far what I got is the following...

• Piston engine fuels used by the USAAF, USN, RAF & RN FAA: 6.02 lbs/gallon (US)
• Engine oils used by the USAAF/USN & RAF: ~7.5 lbs/gallon (US)
• JP-4: 6.55 lbs/gal
• JP-5: 6.84 lbs/gal

I could use data on the following

• Piston-engine fuels & oils used by the Luftwaffe
• Piston-engine fuels & oils used by the USSR during WWII and Korea
• Early gas-turbine fuels & oils used by the Luftwaffe
• Early gas-turbine fuels & oils used by the USSR
• Early gas-turbine fuels & oils used by the USAAF/USAF
• Early gas-turbine fuels & oils used by the RAF & RN:FAA
• Gas-Turbine Fuels & Oils used by the USSR from 1953-1991

Nobody have anything?

Pretty much gasoline is gasoline.

Jet is jet fuel and lubricating oil is lubricating oil.

sources may differ a bit a bit, especially going out to the 2nd decimal place, just about all of these products are going to be within a few percent of each other. That is lub oil to lub oil, etc.

Even early jet fuel (kerosene) only varied from 0.78 to 0.81 specific gravity over three grades of US fuel and one British fuel.
JP-1,JP-2 and JP-3 falling on or between the weights you gave for JP-4 & 5.

One chart I have (small and skimpy for western fuels/oil, 1948) lists densities at 60 degrees F (15.5C). temperature is going to affect weight to volume as much and probably more than source or country of origin from a practical standpoint.

6.5 to 6.75 lbs/gal?

Could you post that?

Luftwaffe Piston engine oil was about 0.91 kg/liter
Luftwaffe Piston engine fuel varied between 0.74 and 0.78 kg/liter. It seems B4 fuel was originally 0.76 kg/l (Bf 109E/F, Ju87B, Fw 190A-1 load plans) but later became 0.74kg/l (Bf 109G-6, Ju 87D load plans). C3 fuel is calculated with 0.78kg/l in Fw 190 A-6 to A-8 load plans.
Jumo 004 jet fuel was calculated with 0.84 kg/liter (Ar 234 load plan)

Which would be approximately 7.594318 lbs/US Gallon

Luftwaffe Piston engine fuel varied between 0.74 and 0.78 kg/liter. It seems B4 fuel was originally 0.76 kg/l (Bf 109E/F, Ju87B, Fw 190A-1 load plans) but later became 0.74kg/l (Bf 109G-6, Ju 87D load plans). C3 fuel is calculated with 0.78kg/l in Fw 190 A-6 to A-8 load plans.

So...

• Early B4 Fuel: 6.342507 lbs/US Gallon
  
• Later B4 Fuel: 6.175599 lbs/US Gallon
• C3 Fuel: 6.509415 lbs/US Gallon

Jumo 004 jet fuel was calculated with 0.84 kg/liter (Ar 234 load plan)

Which if my math is right, is 7.01014 lbs/US gallon?

 

[Shortround6]

• Early B4 Fuel: 6.342507 lbs/US Gallon
  
• Later B4 Fuel: 6.175599 lbs/US Gallon

The difference is about 17lbs per hundred US gallons. You might get that kind of difference if fueling up on a hot day or a cold day.
Most of the differences have little, if any, practical value.

The amounts are noteworthy in that they are heavier than fuels used in the US/UK...

Okay, I'm adding some stuff about things I've found with German fuels

German Blue Fuel B.4
Specific Gravity: 0.7408
Pounds per Gallon: 6.1823
Octane: 69.5
