Today a tanker arrived as arranged, and said that they had put 1000 liters of oil in my tank. With a delivery printout to prove it.
4 hours later the remote oil gauge is reporting that the tank is completely empty..yes, its getting signal - not a 'no signal' condition. But a 'tank empty condition'
I will be going out into the murk with a dipstick of course, but can anyone suggest WTF is happening, apart from the chilling prospect that the tanker simply didn't put in anything at all?
