I have a 94. I just redid my plugs and plug wires. Went to Bosche, all the wasy around. Before that, I averaged about 18 in town and 21 hwy. Now, I seem to be getting about 20 in town and 25 on the hwy. I too also have a HUGE piece of lead in my shoe.

I just drove my '94 w/ 4.6L from Phoenix to L.A. doing 85-100 mph & got 21.7 mpg. Mine's all stock, but looking to add exhaust, rims, lower her & ground effects. ANYONE have any suggestions? Thx, My

Around 24 here 90% highway miliage. Getting rid of that Violin Case brought me up from 21.

I get 14 and 15 in the city. I don't think that is too bad considering how we drive these 8's.

Re: Gas Milage

I myself on my Thunder, I average about 17 city, and 23 highway, but I also need to change the plugs and wires, and clean the injectors, maybe with any luck, changing those things will get me to 25, but also keep in mind a few factors here, first: a V-8, most V-8s do by far much worse than that, second: rear wheel drive, it takes a little more to get the power to them wheels than a front drive car, and third: a/c if you are running the a/c that is known for robbing a few mpg's, and last: what has been mentioned, the foot, I too am just as guilty as the rest of you for putting my foot into the pedal a little more than what I should, lol.

but all in all, I have to say that with all those factors involved, I personally am happy with the milage that I get, sure I wish that it was better, but for what it is, I think that it's good milage, heck fire, there are some 4-bangers that don't get that good, lol.

with my car, the only mod that I have done to her was run straight pipes on the exhaust, and put in a new mass air flow sensor, other than that, I haven't had to do a thing to my baby.

have a good night all

Running a 3.08:1 differential in my 93, I'm nailing 22-24 city, 30-32 highway.

Most cars can get me off the line-but my top end is 152mph

21.4 mixed driving. Should go up. I just did a tune up and cleaned the MAF.
