Thats what I figured like you said its to hard to show sarcasm! Folks just need to laugh a bit more I think

 

I do agree, too quick to jump on things.

 

I can see it. 93 has the vortec so it gets better mileage than a TBI, and im sure you have the 3.04 rear end (or what ever the lowest gear is, 3.05?) and its a 2WD so thats even better. if you were driving mostly on flat road at highway speed, not a lot of passes then 28 sounds about right.

I would get about 22 in my truck on my 200 mile round trip to work and back every weekend and that was up a pass and back. and with 31's

 

technicaly its not a true vortec engine unless it has the kidney bean chambers inside.What Gm called the early Vortec engines are no different that a regular 4.3 V6.The real vortec engine didnt come out till 1996 when GM changed the head design.Not totaly sure but I beleive the gear ratios were 308,3.42.373,and 4.10 in the Jimmy.Realisticaly your milege should be 22mpg Hiway and 15 City.You said you have a free flowing exaust system,I can possibly see 25 and 16 mpg.Then I looked up mpg`s for newer Jimmy`s,seems like the newer they are the worst mpg they get.

 

I have the 4.3 with 3.42, 4wd and I wish I could get that mileage.

 

My 98 4x4 has 3:42's, 212K miles, injector upgrade, everything else is stock. My wife gets just over 25 with it. I must have bigger shoes, best I get is 23 Doesn't really matter to me what the fuel mileage is, it gets what it gets. I like the truck, I take care of it, it's dependable and it was paid for 12 years ago.

 

I've been running my '93 Jimmy lately while I work on my '98. The '93 gets about 19mpg on the freeway. I got 18.5 going over the mountains to Leavenworth and back last weekend. That was with three other people and a lot of instruments in the truck.

 

My favorite is the fullsize 94

 

My bone stock 93 4x4 with 3.42 gears got 22mpgs from central pa to wilmington nc and back. 560+ miles one way, and we drove around a lot down there. It's amazing if you just set the cruise at the speed limit and go. I'd like to throw a free flowing exhaust on it, but the exhaust that is on it is fine for right now (till it rusts out this winter). I love these vehicles. Wait, actually, I love the first generation of these vehicles. I'm not exactly sure what Gm was thinking when the designed the 2nd gen. Probably something like "how can we take a nice manly looking vehicle and make it look extremely girly..."

All offense intended :-P (that's meant to be sarcastic)

 

What was GM thinking when the built the 2cnd generation With the exception of 95 I would sure like like know.From 96 on they changed everything and went down hill from there.
