Ok I think I get the drift here,
I asked what I thought was a sensible question.
Heating oil is kerosene 28sec
Turbine fuel is KEROSENE 50 sec
I didn't intend filling the tank with a rusty old bucket,
And the guy further up is not the first to say that heating oil and jet a1 comes from the same tanks at the fuel storage depot !
If you must know my pilot mate is pilot part time and tanker driver day job and he assures me he know what he is delivering to airfields where you lot, and me now fill our aircraft !
And there have been occasions when he has delivered to an airfield and then 500 gall to a farm for heating oil ! Out of the same tank on the same truck !
Before someone says trucks have separate tanks within them !
I am sure the tanker driver knows his job !
I am only telling you what he has told me !
And thought this forum may be a good place to obtain confirmation.
So let's leave it there and all continue to fill up at the airfield with what we assume is jet a1, when in fact it could just be heating oil KEROSENE 28sec.
