Real MPGs for your rig?

Well then, the diesel Jeep Grand Cherokee might be what you want. It’s medium sized, not quite small, but then again it seats only 5 so it’s on the small side.

Mine is a 2016 “JGC CRD”, 8-speed auto, with 255/70-18 A/T tires (32”) on a stock Quadra-Lift suspension, and a roof rack with small space case. JGC CRD = Jeep Grand Cherokee common-rail diesel — Jeep calls it the Eco-Diesel, but E.D. is something you buy little blue pills for so I call it the JGC CRD.

Using the paddle shifters to upshift a little early and hold a higher gear, and also by not driving fast, lately I’ve been able to get 25-30 MPG on the highway, and 20-25 MPG in the city. If I don’t do that, and if I drive “smartly to assertively”, I get 19-24 MPG in all-around driving.

But once, there was one time on a long trip that I tried hyper-miling it — on a flat I-5 from Los Banos CA up to Shasta and then south to L.A., using paddle shifters to set and hold 8th gear, I got 34 MPG for an entire tank. The tank holds 25 gallons, and 34 MPG means that I was able to go 835 miles between fillups on that drive. That 835 miles is the farthest I’ve gone on a single tank, so far.

30-34 MPG is not too shabby for a decently trail-capable 4x4 rig.

I couldn’t swallow the Jeep part. I’ve seen 20mpg highway in my FJ40 brick. 33s, lift, 6’4” before the rack. It has room to improve on mpg if it had a newer carb. It has 250k miles and will easily go for another 250k miles of whatever I can throw at it. With open diffs it doesn’t seem to like snow over 3’ deep... unless it’s firm enough to climb on top of.

The quality of build and the durability... compared to a Land Cruiser. Don't get me wrong, I've seen some really nicely built up jeeps... after dumping a fortune into them they reach what I started with. Although some of the newer Jeeps are getting better, it's hard to forget.

I'm old school. I've got a '74 and it has 9.5" ring gears out of the gate. It has a 1 ton drive train that makes stock Jeeps look wimpy.

But does it have heated seats and bluetooth? :D

What's a payment? Do you mean paying for gas? Or paying for it in full with cash.

What are heated seats? Why would I want to have a blue tooth? Radio hasn't worked in years... and even though I've had a spare sitting on a shelf for 15 years... the 350 with an RV cam and dual exhaust has been all I have needed for "music". May need to install the stereo now that I've switched to an almost silent single exhaust... but the 4 barrel still makes its own note.

Not sure you guys got the joke.

I love old vehicles but modern creature comforts are nice too.

Just calculated 12.7 on hway some traffic mostly running between 60-70 mph.

Looks like I’m getting around 14 + ish on most recent trip.
I think I miscalculated last time since I did not account for larger tires!
