    Downsizing tires for mpg

    Hello all- I am the happy recent owner of a '99 4.0. Previous owner added all terrain 31' tires. I hardly offroad and am looking to downsize to something more stock level, maybe 27', that is more fitting for cruising in the city. Do you guys have any insights on the mpg impact ? I imagine most...

    Fuel consumption

    Hey, I know the TJ's aren't the best on fuel but from everything I've read the usual consumption is around 15MPG. I get around 10 MPG... I have 31-inch mud tires, a 2-inch lift, and fully unloaded all the time (1 person fairly light, no seats or anything in the back, 0 luggage). I've noticed...

    What MPG are you getting?

    Hey all. Just read a thread about folks getting 17mpg and 18mpg in their TJs. I have a 4.0, auto, running a 3.5” lift and 31s. Tires are bf goodrich mudterrains. My average mpg is 10mpg, with 11.5mpg being my highest. That was me doing everything I could to keep in the overdrive “gear”...

    Sudden drop in MPG

    Good evening everyone, I've recently noticed a drastic change in my Jeeps gas mileage from around 15mpg to now 9-10mpg. I'm pretty good at keeping up with the maintenance (no check engine lights), and I know my lift & 35" tires don't help but I've had those modifications on for the past 4 years...

    2005 2.4 TJ - Very Poor Gas Mileage & Loss Of Acceleration

    Hoping someone might be able to throw me in the right direction, I have a 2005 2.4l TJ and most recently, I've been getting very poor gas mileage (9-10mpg city & highway), & it's been taking forever to accelerate, I went 30-60MPH today and it took nearly 15 seconds and that was me shifting...

    Anyone own a TDI?

    The wife and I are looking to replace our CR-V with a family car that gets better fuel economy. Something that's come of interest is a Jetta TDI Sportwagon. I feel like that would be a decent family car since it's a hatchback, has room for both the kids, and room in the trunk. However, I have a...
