365 miles. ONE TANK.

[VehiGAZ]

I learned the hard way on that

You and me both.

You folks need to try Lucas gas treatment. (No, I don't own stock in the company.) It costs $10.00 for 5 tank fulls and you get 40-50 more miles per tank. A no brainer at today's gas prices. Also, try 39 lbs of tire air pressure, it helps our mileage, as well. Less roll resistance. Keep coasting and taking it out of gear at lights, but keep the PRNDL linkage well lubed with lithium grease.

I have 356 on mine right now, the light is on but I am lifted. I also am doing the acetone mixture.

I get in the mid to upper 300 all the time now. The best tool you can buy is a Scan Gauge II, it really helps you monitor you driving and helps you keep the power consistent on the freeway. Its like a game to try and keep it at 20 mpg.

I actually just filled up 20.20 gallons with 361 on the tank....I used to barely get 270.

[Jolly Roger VX'er]

Just got 356 miles out of tank with low-fuel light on steady for about the last 10 miles. I was going to go for the gold (366 miles) but chickened out....bok bok bok...cluck....cock-a-doodle-doo.

I honestly did not believe you as I have tried these things before with very little effects, but I just got 2+ more MPG on my last trip using the Lucas Fuel system additive, thanks, I will be trying this out some more.

ok, I'm sick of being the low man on the totem pole on this, I've not scratched 300 except for a couple of times and typically ALWAYS get 270 on a tankful, it's annoying hearing all you people getting mid-300's
grrrrrr!!
I was going to mess with the spark plugs to see if they're in need of replacing but I will also try the lucas tx first, ANYTHING will be an improvement here....

[JHarris1385]

Change fuel filter. And then tell me about the exhaust you have coming out at idle?

[Joe Isuzu]

fuel filter changed at 90k

[Joe Isuzu]

say, here's a thought I had this morning
I'm running at factory settings for the tires which I believe is 30, I'm certain it's low to try and improve the ride or to improve your off-road ability (guessing on that one)
all you lucky dogs who are getting such great mileage, what PSI are you using in your tires?
that would be an easy fix if everyone is running higher than stock, I realize the higher the pressure the better your mileage but also the more quickly it wears out the middle of your tire so I'd like to find a happy medium if everyone IS running increased pressures

I forgot to address the exhaust question, I guess I didn't quite understand your question. If you're talking about the rev's maintaining a high number even when you lift off the gas, that got remedied by bleeding some surplus tranny fluid. It's still not the way I remember (could be my memory) it but it's definitely better than what it was. Exhaust is still loud to me but I'm learning to adjust for the time being.
I got the gas tx last night and pumped up the air pressures. Keeping my fingers crossed.

I think what J is getting at is... does your exhaust seem like its coming out too fast or smell rich of something (more specifically does it smell like fuel?) if it does, a likely culprit would be your fuel pressure regulator, common problem and typically replacing it is good for 2-4 mpg
