Most Rolls-Royces you see have engines in excess of 6 litres, so you can appreciate that fuel economy has never been a major consideration for the designers or owners.
The earliest cars - the Silver Ghost and New Phantom - have been known to do better than 20mpg (14l/100km). Generally we find they do between 12 mpg (24l/100km) and 15mpg (19l/100km).
Early post-war cars have engines around 4 litres capacity, but the fuel consumption tends to follow the same pattern as for the larger engines.
V8-powered Rolls-Royces may exhibit different behaviour, but I don't have any experience with them.

MK VI 4.5 litre, fuel consumption at a constant 30 mph, 22.5 mpg. From "The Motor" 10/10/51.
This is around 1500 rpm in top gear.

As the proud owner of a 1962 RR SCIII using a relatively early V8 6.25 litre Rolls Royce engine and a 1989 Bentley Turbo R using the latter version of the V8 at 6.75 litres I feel qualified to say that fuel consumption of the V8 is best ignored!
On a good run in the Silver Cloud III we get about 14 mpg and I get about 15 mpg out of the Bentley on a daily commute involving lots of sitting around in London traffic.
I hope that fills in that area for you.
