View Full Version : 80 series fuel mileage expectations

I've been looking pretty closely at a 1996 Lexus LX450 (165K, all stock, f/r lockers) and am wondering what the real world mileage expectations are with these rigs.

I wouldn't be too concerned except that every good trip for me starts and ends with 1300-1500 or more highway miles.

Lay it on me. I can take it.

For the last 6 months, I've averaged ~ 14mpg in stock form with mixed use driving. Range is 12 - 16mpg.

When mine was stock 14city/16HWY on summer fuel mixture. Dropped a little when the winter fuel showed up at the gas stations. 18+ a few times on the HWY. Keeping it under 70MPH is the key. More than that and fuel consumption goes way up in my experience.

Now I'm down to 12 with 315's, 2" lift and some armor.

I would hope you'd do a little better than us at lower elevation.

I am running big 36's with 4.88 gearing. 6inches of lift and I monitored it closely on my trip to Alaska. Lower elevation gains once out of the lower 48 but I was averaging around 13.4-14.2.

Around Colorado's road trips (think Denver to Moab) I get about 11-12 MPG.

Around town it's around 10-12 depending on how I drive.

How much stuff in my vehicle doesn't seem to matter since the more I have the slower I go so it's all relevant. Mostly do 70-75 on the highway unless loaded then 60-65.

Yup, mid 12's around town, 14-15 if there's a good dose of highway. Not stock though, that's 35's and 4.88 gears, easily 1000 pounds of extras.

Those numbers sound pretty close to the rated 13 city, 15 hwy. Just what I needed to know. I think I'll ponder on this during the Maze trip. If it's still available maybe I'll put an offer in. If it isn't, well, then I'll still have several greenbacks in my pocket.

I probably get around 12 MPG too. Supercharger, 4" lift, 315s, bumpers front and rear, sliders, Iron Pig skid plate, huge M12,000 winch, drawers in the back -- yeah, I'm carrying some extra pounds.

You will get about 1.5mpg better with a 100 series.

There is no substitute for the real thing. I'll let you gas up my 80 this trip and I'll gas up your FJ! :lmao::lmao::lmao::lmao::lmao::lmao::lmao::lmao:

I get 16-17 on the highway pretty consistently but I have stock gearing, 33s, and I don't go over 65. Plus I have an OBDII gauge that tells me instantaneous mileage and I fixate on it; it's like a contest and if the long term mileage drops a tenth of an MPG I feel like I've lost. Driving can be monotonous and you have to do something ;)

I think gearing and speed will be the death of mileage.

i have stock gearing and 33's and get 17 on summer gas and about 15 on winter. it all depends on how your drive, how much air is in the tires and what you have loaded in the back. I wouldn't buy this car if you are concerned about gas mileage. i would buy it because you've always wanted one. the gas will cost what it costs. my advice, buy it and don't look back. land cruisers are the best!

Gotta pay to play. :lmao:

Most people with built FJCs complain about mileage too. Although I do not have mud tires and haven't regeared, I can get 19-20 mpg if driving 60-65 mph and that is pretty good compared to what most people are getting with cars, minivans and pickups across the land.

What grade of fuel are you running? High grade= a higher yield of mpg. But not much. Make sure you have accurate air pressure in all tires and your engine service is up to date.

Matt...Question that has burning a hole in my noggin :)

Have you noticed any appreciable change in your MPG figures since installing your SC?

My theory is that you will get the same or slightly better gas mileage (once the novelty and lead footing syndrome wears off :hill:) with a SC as stock because the engine while using more gas (maybe) doesn't have to work as hard to move the beast around...

I came up with this theory after borrowing my FIL's Dodge 2500 with the V10 in it. We averaged over 20 mpg to Moab and back, pulling our popup camper. The truck didn't even notice the camper behind it.
