On my 4.2 with 149K mileage and unknown maintenance prior to Sept 07 when I bought it, I'm getting an average of 13.66. Highway is in the 15s and daily driving is 12-13.

I'm pretty close to yours... 139k, rebuilt top end (head gaskets, valve job, etc) as of 500 miles ago... 12mpg +/- around town. I'd be shocked if it did better than that!

Basically bad to worse...

Mine's the same way. It's completely original (with exception of OME 2" lift) and stock with 225k miles. I still run xpc's. Mid to high 11 mpg in town, mid to high 16's on the highway is all I get. I've gotten 18.8 twice out of it but I haven't seen that in over a year. I used to get almost 1 more mpg before I took off the front air dam.

But do you really care? I know you didn't buying it because of it's reputation for being green. :) Shitty is shitty. And it doesn't get much better.

I'm running 265's on Procomp steelies, half rack, 3" lift and I get about 12-13.... was about the same when I was at a 1" lift and 31" tires w/ stock rims.... I think the roof rack definitely makes a difference tho...

That's exceptional with mods. Is that taking the info from the Odometer? Or using a GPS? As you realize when you change tire size, the odometer and speedo are giving you skewed info.

Mine is dead stock. I don't have an exact calculation, but I'm sure I'm within the same range as the rest of you guys.

I think you summed it up, though...shitty gas mileage, and not really a damn thing you can do to make a substantive difference. Substantive being a consistent 15-20mpg. I don't see a 1mpg or two being significant.

It's a hog, it is what it is. Tell ya, though...I think you would be surprised that many much newer trucks(Escalade, whatever) do considerably worse...

That's a straight conversion from the odometer. I think taking into account the different tire size, it should be actually better than that... but that doesn't make sense though does it.

BTW, mine's a 95 4.2 w/ 109K

True enough. Our Trooper with the 3.5 V6 and slightly less mass gets 15 coasting down hill. Even the new hybrid Tahoe is only getting 20. If I invested $40k, the cost of a Tahoe, into the RRC I could get better than 20.

93' Stock tires with 123k miles, got 13-14 mpg,added front brush guard,roof rack and am lucky to see 11 mpg. Which is why I am leaning toward selling both the 93' and 90'. $3 a gallon is killing me since it is a DD with 60 miles a day to work.

By transferring the rover body onto a Tahoe chassis?:victory:

That's very interesting! I have no brush guard and no roof rack.


I do remember thinking I got at least 2-3 MPH more than the 4.2 does with my older Rangies like the 89 and 90 ones...
Yup, $3 a gallon(actually, more like $3.50 where I live) actually really hurts, I commute some 300 miles per week, it matters.

Not trying to hijack BUT:victory: I wonder how many guys are using a RRC as a DD? It is very easy for me to run 350 + miles a week between work and running around. The "boss" (wife) has just about twisted my arm to the point of selling out and getting a new DD. I am resisting but it is starting to make since.:( Even with correct maintence how long should you expect a Classic to live adding 350 miles a week to it?

Funny you mention this as my boss (wife) is going from a '05 Volvo XC70 DD to the RRC as her car. She wants to drive something that she doesn't have to lease and having 4 cars is a little silly if 2 of them just sit... She does about 250 miles a week in normal use and the way we figure it, if no car payment on the RR, I don't care about the fuel cost until the outlay there is equal to the cost of a new car and the fuel/insurance for that. If the RRC lasts 2 years before a prohibitive repair, so be it. I do mostly my own work and am not afraid of stocking up on donor cars, so it may be a while before it goes away...

Hybrid Rovers would be interesting. However, I think Diesel's the way to go in the long run. Mechanics are straightforward, but the challenge I've found is in the legality of engine swaps for newer cars. Converting gas to diesel is a sure way to get an "off highway" truck that won't pass any inspection, at least in Texas.
I believe that oil prices are entirely artificially set and if we, as Joe Public, spend our money buying hybrids and electrics with unpredictable futures at premium prices, then the oil and automotive industries will never change. Driving inefficient Rovers, Troopers, and the like en mass and whining about fuel prices to our "leaders" will eventually force fuel prices down, average fuel efficiency up, and possibly bring about other side effects such as mandatory work-from-home, shorter work weeks, mass transit, etc. Hybrids are cool and vogue, but the people buying the Prius won't change policy like a middle-class family of 5 that can't buy shoes and food for the kids because their '99 Suburban costs $100 a tank.
I will do my part for society and continue at 13MPG for all of my vehicles and bitch about it every 200 miles at fillup. God Bless the USA.

I don't think you can rely on these instruments to be accurate even with stock tires. Running Michelin XPC 255/65's, my speedometer is off by almost 7%. I can't imagine what the difference would be with altered tire sizes. Oddly enough, the odometer is more accurate with only a 1% difference and I don't get that one at all. My old Discovery 1 was the same way and had the same tires. I never checked the odometer on it but that speedo was off by close to 6%. The difference in diameter between the stock 205/80 and these tires is only 0.14", not even 1/2 of one percent.

Regardless, shitty is shitty. Just make sure you're measuring correctly so you can really cry in your Post Toasties.

Tiger, if I were you, I'd be tooling all over in the Healy or the Morgan anyway. Both are very cool rides.


Happy Rovering,
