- somehow lower the Jeep a few inches (since lowering a vehicle has a significant improvement in Cd.)

Uh.. that ain't happening. Sorry, but I'm all into the whole Ecomodding thing a whole bunch but, lowing a Jeep is like neutering a very large dog. Jeeps and dogs are alike. They become mans best friend Good suggestion tho.

When are you going to start your gaslog??

Just filled up today. So.. Whenever I fill up next is the start of the gaslog I guess?

Grill block, and a front belly pan right away and work on the rest of the undertray later.

I just did a grille block today actually. And... it seems to be working wonderfully. I noticed it right away. I took the whole family out, and the rpms dropped about 100rpm, despite having 4 people in, and using stap-on-the-headrest dvd players. I used duct tape because it is gray like the plastic on the bumpers, and it won't deteriorate like cardboard would. If you'll notice in this pic (if it's too big please resize) that there is 2 grilles, and I taped off the lower one. It is at an angle for a better approach on those dips I hit on a daily basis. It seems to work, and a lot better than I expected (all other aero mods seem to disappoint). If you can't see it turn up the brightness or down on the contrast to see.

Soon I'll get a pic of what the grille block looks like, this I guess you could say is a "before" pic V

a front belly pan right away

Yea, I was thinking about that. How to start it off tho? and how far should I go? What should it be made of?

Might also consider a higher temp t-stat

When I bought the vehicle, the old t-stat was going haywire, so I replaced it. Not sure how hot it is, but it was a pain in the you know what because you need a specially bent tool to reach it.

Did you get the vacuum gage?

Nope, not yet, do you know of any stores that carry them(less use of the credit card/debit card over the internet).

I think we need to see some gas logs so we can gauge any improvements on the mods that you make.

Working on it

I'd also consider a block heater or 120v interior space heater

Once again, where do I get one? and how exactly do I use it, does it plug into an outlet?(I can tell with the 120v one you do). Do I hook it up to a coolant line?

Look at the latest crop of GM SUV's: they all have significant air dams below the front bumpers. You could make a removable one so you can still have your approach angle for playing in the mud.

Just goes to show everything is not for the utility part, but for the let's go to the gas station to get krispy kreme donuts and some gum vehicles. That part would be hard. and I'd tear it up anyway on the way to school from the potholes in the cobblestone roads.

Get a new tailgate and install a boat tail to that (on top of air dam and such).

Why get a new tailgate when I could just use the torx screw mounts that the roof racks used to be mounted on? I could use flat metal pieces and clear plastic to make a kammback, attaching the flat metal to the last screw holes and going down the rear of the vehicle. Easy removal, unscrew and it's like normal.

Tomorrow I'm changing the oil because I'm a little over do and I've got the oil, It's Mobil 1 5w-30 Truck and SUV Full Syn motor oil. I also got a can of sea foam to try and help get out whatever gunk and sludge, water or whatev that has built up in the crank case and cylinders, and valves. I've used Sea foam before in my fuel and unlike everything else it seems to really work. swiped those injectors clean. Last oil I used was Mobil 1 High Mileage 10w-30 Full Syn motor oil and helped oil burn off quite good.

Previous owners didn't know squat about maintaining a vehicle. I bought the thing with no oil on the dipstick, had 7500 miles since the last oil change, really low coolant, failing t-stat, really low refrigerant level, Spark plugs with almost no electrode with a gap double of what it's supposed to be. A fuel filter so clogged the fuel went in clear and came out black. a leaking differential, tranny fluid that hadn't been changed in centuries, and lots of other things I don't wanna bore you with.
