RE: miles to tank... i need input
My way to check bad gas milage: pull out one spark plug on each side of the engine to check for fouling/charring/wet fuel. If one side is darker than the other/other side is clean, that side powertrain has: a bad spark plug on that side, broken o2 sensor, near-clogged cat (glowing cat,backfire,power loss, bogging down), or bad wires. if both sides of plugs are charred, check distributor/wires/cats/muffler. If all plugs are clean after checking, check air filter, if looks desent, check the structure of filter (is it pulled in toward tb?) if all checks out..go back to 02 sensors, check them out, or bad fuel system. I played around with my trucks milage with this checklist..replaced plugs,wires,air filter, had mottoVAC done, replaced one cat, added straight pipe, replaced all o2 sensors. None of these fixes help 4x4 gas milage: 4MPG..cant wait till winter! love v10's

Motorbreath, I just don't like wasting time or money.
Example 1: You and your misfire.
If I thought I had a flat tire, I would ask people how I can figure this out (if I was that stupid). I wouldn't ask people what they are getting for mileage to tank to compare if my inconsistencies supported my idea about a flat tire. Instead of running multiple tanks of fuel through my truck when it is clearly a) not running right and b) definitely has a problem that I can narrow down, I would like to find the most efficient way to trouble shoot to save me money, time, effort, and tons of problems.
Same to you. If you thought that you had a misfire, ask us about a misfire. Not about mileage to a tank. When you take your vehicle to a dealer or mechanic and ask about a misfire, do you think the first trouble shooting step would be to drive it for hundreds of miles to determine the fuel usage and compare this with what it should be getting, or do you think that they would check the ignition system?
Example 2: Making an air filter out of a 1984 Cadillac intake
Why would you even bother. Engineers designed the factory intake. Leave it. Or if you want to change it, go buy the correct after market FIPK.
I'm sorry to offend you MB. I just like to do things correctly. I'm not one to cobble or try to figure out the hardest way to get from point A to point B. I mean, if you have fun doing things the long hard way, rock on!

RE: miles to tank... i need input
OK, I'm sorry but I gotta back track here.
1. Where in MRFREEZE's sig. does it say he's got a longbed with a larger tank?
2. If that is the case then a 35 gal. tank by 550 miles =15 and change mpg (running it dry) and that's a more reasonable figure for a road trip and I give him that.
3. 550/30 gal=18ish. Starting to push the BS meter, but not impossible.
4. Dakota; depending on load, etc. about 1000lbs less than a Ram. Sure, 18 doable.
5. Yes, I saw the edit note.
6. Wouldn't even believe it if I was there!
7. Aim... you're pushing me into a place I don't want to go.

RE: miles to tank... i need input
Ok,heres the deal.I reset my odometer when I filled it up after the 550 trip.Gas light was on for about 15 miles before I hit the gas station.When I got to the station I filled my truck up.It took a little over 27 gallons to top it off.I made 500 off the next fill up on the way home.So you draw your own conclusions.Im not gonna argue about it.Makes no difference if you believe me or not.I've stated my facts.It is not a 35 gallon tank.

RE: miles to tank... i need input
Mr. Freeze, I know I have the 35 gallon tank and I can hit E and fill up with only 28 gallons. I'm not trying to rail you or anything, because you probably didn't use all 35 gallons if it's anything like my truck. Somewhere on the truck it should say, can't remember if its the glovebox sticker, the driver's door sticker, orunder the hood. It would be something useful to know though.
I'm actually a little envious at how you got that mileage, as I've got basically the exact same setup on a newer truck and only get around 18 or so if I really behave on the highways.
