No it does not, if that were true it would not matter how you drove a car,you could measure fuel consumption by rpm only, this is obviously not the case. if your figurs above were correct, a 2litre engine would need 0.15 of a litre every revolution or 450 litres at 3000rpm???

No it does not, if that were true, assuming an average fuel tank size of 60 litres, that means you could only ever run your car for a maximum of 30 minutes till you emptied your tank - have you ever driven for more than half an hour?

that may well be true, no idea,
