classics ???

I have been considering a RRC. What kind of MPG do these truck get with various engines that are stock.
I know you do not drive these for fuel economy.

i have gotten somewhere around 15mpg, but have been told that i can do better.

Best I got on my 92 Classic was 18 mpg.
On the 97 5 speed Discovery, it regularly managed 21 to 22 mpg, was happy with that !

which engines?

mine is a 91 RRC, 3.9 liter with about 187k

1995 RR LWB 4.2 My engine is new with about 6,000 miles on it. In Los Angeles traffic, combined freeway & streets is 11.5 mpg.
I just completed a 3,000 mile road trip and I recorded my mileage. (No cruise control, it died just before the trip).
At 55/60 mph the best I've had was 16.7 mpg.
At 75 around 13.5 mpg.
The mpg is pretty much the same as it was with my old engine.

15 mpg seems to be about as good as it gets for a stock engine. I had modified my '95 Lwb 4.2L and got about 22mpg on trips. How? Bosche gen III injectors (for a Ford Mustang 302, with four spray holes), K&N air filter, high voltage coil in cap distributor (for a Buick), custom dual exhaust, synthetic oil. A lot of monkeying about, and money spent, for a few mpg. My '70 and '76 V-8's are 3.5L and get about 15 mpg also.

'99 Disco II
'95 R.R.C. Lwb (Gone...)
'76 Series III Hybrid 109
'70 Rover 3500S

completely stock

1990 RRC w/ 3.9L - 12-17mpg
1995 LWB w/ 4.2L - 15-19mpg

The gas station is like a second home

10-13mpg on my 400k miles in 4 different classics.

Over 1300 miles last week our current 1995 RRC LWB returned a 15.3mpg average and best tank was 16.1mpg. This is a bone stock 4.2L with 53k original miles. On our 1996 D1, owned 16 years since new, I would get 15mpg pretty much on any paved road.
