New Ideas for The Eco-Wall

[DifferentPointofView]

- 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.

Yes they're 120V. No way will a car battery have the ability to warm up the block. Calcs have already been done (cleanmpg.com, I think) to prove that the cost of electricity to run it is less than the cost of the gas you save. Burning fuel to heat the block is pretty costly - and that's exactly what we all do every time we start a cold engine. I've seen posts from people using them year round. Engine goes into closed loop operation almost immediately and has all the benefits of being warmed up, right from the get-go.

You can ask at a Jeep dealer. I wouldn't be surprised if they can get them.

I'm pretty sure jcwhitney.com sells 'em, or buy from a real parts store. I wouldn't expect the "big box" parts stores to stock them but traditional parts stores, yes. In my area we have NAPA, CarQuest, BumperToBumper - those guys.

The good block heaters are the ones that install into a freeze plug opening. Heater replaces the freeze plug. Reason is, that lets the heater warm up the main body of coolant in the block. The heat disperses well into the block to warm it throughout. I think that's the type that's most common up in northern US and Canada where lots of people have block heaters.

Another type installs into the heater hose. It needs some circulation to carry the heat to the engine. Probably easier to install but a more complex design and concept. If there's no pump in the heater unit then it's relying on convection to carry the heat to the block - not the best way.

Least successful are the ones that heat the oil. Some by a heater pad glued to the oil pan, some by a heater built into a substitute dipstick. Aside from problems when you drive away with a 120V cord in your dipstick, these don't really heat the block, just the oil, so they can't accomplish as much preheating as the ones that heat the engine coolant.

had 7500 miles since the last oil change

Meh - that's young! <--- if there's any left in the crank case. I do 10K mile oil change intervals on dino oil - but have oil analysis done to make sure it's still good when it comes out Of course, this varies from engine to engine (even two "identical" engines )

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.

SUV's have always been more sport and less utility... And by sport - I mean sports less useful cousin, sporty...

Yea I agree that 7500 miles is really not that big a deal. In Europe they go lots farther then the marketing kings here at 3000 miles. No oil on the stick that not great.

On the front belly tray just attach it to the lower part of the front grill and go back to the end of the engine bay. There's lots of choices to use. I think cloroplast is the favorite. It's the stuff campaign signs are made of.

A vacuum gauge can be bought at any auto parts store and probably at wal mart. Search the web you'll find all kinds of stuff.

So I did the oil change yesterday and, you won't believe what came out of it. Just chunks and chunks of sludge and old oil that looked like metal flakes but when I picked it up it was just crap from oil bi-products.

You guys probably don't know what conditions I drive in. But it's not pretty. I live in a place not even big enough to be called a town so it's actually a village. Only the in town stuff is paved and it's paved by laying down tar, rocks, tar, then rocks again. The rest of the roads are gravel/dirt/mud roads. Everything is dusty and full of chemicals from the power plant and whatever the farmers decide to use nowadays. My whole engine bay is light brown and muddy now. It's not regular conditions and it definitely files under the "change every 3000 miles or so" maintenance schedule. And looking at who maintained the Jeep before me.. really didn't maintain it at all. Fuel isn't supposed to be black when it comes OUT of the fuel filter, and spark plugs aren't supposed to look like they just went into a volcano and back. If I had the vehicle the whole time. I'd probably go with longer intervals, but the vehicle is a little rough right now and needs to be maintained at the best right now. Oil change went well tho, I was kinda surprised and not surprised of what came out of there. Runs easier now, especially since it's cold.

Alright, I'll do a search on that now. I went to Walmart to search for a vacuum guage and had no luck, but I'll check the parts stores and see what they've got.

Cloroplast.. isn't that something in plants? That should be in hobby stores or something right? in any event I could get something temporary for the moment.

You could try Auto-RX. Never used it but have heard goods things about it.

If you have a sign shop around you could probably get the coroplast from them.

I've found a vacuum gauge that isn't all that much cash, but I think I'll need a tubing kit. Sunpro makes a tubing kit, it should work with the tubing kit right? unless they design their stuff differently. Does anyone know if they will go together?

EDIT: WOW I'm blind, I looked back at a post about a vacuum gauge and Lazarus posted the exact link to what I was looking for above. I'm blind,

[Peakster]

Don't the Jeep Grand Cherokees come with an instant fuel economy meter mounted on the interior roof, just above the rearview mirror? The ones I've test drove did and even the Quadra-Trac Laredo with the inline 4.0L I drove was reading 30 mpg(imp) at 55-mph.

[DifferentPointofView]

No, That was an option. I didn't have one when I bought it, that was an overhead console option that apparently was not picked, along with 4wd (who buys a Jeep and DOESN'T get the 4wd? Only people who go and get groceries with it that's who.)



Here's a pic of the day, or the day after I first bought it. As you can see, there is no overhead console (or subwoofers). If only they had bought it with the instrumentation *sigh*.

I've found some block heaters, but I can't quite find out what size I need. It's an AMC I6 engine, so if that helps any..
