I've read lots of comments/complaints about the economy we get with our Libb's, so just for the heck of it, I thought I'd check mine close and here is my report for anyone that might be interested:

I drive Interstate-5 to work each day, it is right about 40 miles to work. Libb is a 2006, 6-Speed manual with a 3.7 gas engine with no cruise control, 28K and I don't normally use my defrosters unless I have to. I use regular fuel and no specific brand of fuel.

Libb is lifted 2.50" and has 10 ply 30.5" diameter Cepek M/T tires with 35lbs of air in them. There is also a roof basket w/o a deflector.

I drive however I want, anywhere from 50 to 75 mph. The terrain is mostly flat with two reasonable grades and we go zoom-zoom over them.

I am getting 15 and 1/2 mpg's consistantly. Wish I was getting 20+ but it is what it is isn't it.

I get about 18.5 mpg in mixed driving with a stock '05 with a 6-spd. I do not drive conservately,either. Your left, tires, loss of aerodynamics, & the extra weight might be working against you.

My '79 MAY get 8 mpg's. So, just be happy it isn't worse

At hw speeds the tires and roof rack are killing you.

I can get 18+ with my lift and tires at 70mph. Over that it drops kinda fast.

Yep. The lift, the tires, the roof rack all that stuff that changes the aerodynamics kills your mpg's. Sure looks cool though, huh.

Cold weather and winter gas........I am lucky to get 15 (mixed city/hw) with the pig. I have been driving the car. The Cutlass (28+ mpg even with winter gas) and the pig is in the garage. GM knows how to build a v-6. Course I am making an un-fair comparison. The car is aerodynamic and weighs less and tiptoes down the road like a fashion model whereas the pig likes to play in the mud and snow and suck gas .........like a pig..

When it snows I drag the pig out of the garage.

In the summer the pig is a little better though. About 18 + mixed and about 20 + highway if I am easy on the pig.

With 245/75/16's, Frankenlift, skids, rails, and lightbar,..

I get 26 highway/city mixed (mainly highway). My last highway trip was 28mpg (tend to cruise at an average of 72mph). My last wheeling trip I spent a fair amount of time in 4-Low and got around 19.5mpg-- which is the worst I have ever had.

I'm getting about 15-16 mpg HWY. Winter gas, 2.5" lift, 235/70 a/t with steel wheels. In the summer I get about 17 mpg HWY. It's the city driving that kills me, about 13-14 mpg, luckily I drive mostly on the highway. Can't wait until I get bigger tires, skids and a roof rack....
