BREEZE1 Posted March 12, 2009 Share Posted March 12, 2009 Mine isn’t running right and hasn’t had a tune up yet. It idles at 1500 rpms so that doesn’t help. Its gets 15mpg as is, with 4:10’s 35” tires. My goal is to get it in the low 20’s. I am about to swap to an HO head, intake, 62mm throttle body, & better exhaust. I think that should help drastically. O yeah, ill give it a tune up also. :clapping: Link to comment Share on other sites More sharing options...

pantera1973 Posted March 12, 2009 Share Posted March 12, 2009 I'm usually between 9-13....this is mainly just driving around town 30x9.50x15 on Crager D Windows and my Speedo is NOT corrected....so mine may be alittle better than I'm reading Exactly. I believe that lots of folks actually get somewhat better MPG than they think they do. You are actually traveling 6% further in your case than you thought you were (assuming your stock size was 225/75/15. ;) Here's a great link to see how much a tire size change affects things: http://www.1010tires.com/tiresizecalculator.asp I had an 88 XJ 4.0 5-speed, 3.07 rear that I bought brand new (wish I'd kept it) that I used to get 19 city and 24 hwy without trying too hard.

WyoCherokee Posted March 23, 2009 Share Posted March 23, 2009 just got back from a 1600 mile round trip..... 26mpg's at 70 mph, 21mpg at 70-75 going through the mountains, and 23mpg at 75-77. Link to comment Share on other sites More sharing options...
WahooSteeler Posted March 23, 2009 Share Posted March 23, 2009 IMO i think they should just do away with speed limits i mean who needs em? :rotf: Move to Montana then. During daylight hours there are stretches of highway where there speed limit is "reasonable and prudent". Seriously. :D Link to comment Share on other sites More sharing options...
johnj92131 Posted March 23, 2009 Share Posted March 23, 2009 My last two full tanks gave me about the same thing. Between 15 and 16 mpg (15.6). Truck is a 91 High Output with a stock engine. Transmission is an AW4 with a 3.55, 2 WHD and 235/75 x 15 tires. Long bed with a Snug Top shell. Weigh with me in it is around 3800 lbs (I think). This included a couple of hundred miles of freeway driving out of about 700 miles. Have made no effort to correct odometer reading for the larger tires. If stock tire size is 195/75 x 15, then I cover about 9% more distance that the odometer says. That would put my fuel consumption up to about 17 MPG. Reasonable. Think my dad got about 17 mpg on his new 1956 Chevy V8 with PowerGlide. Link to comment Share on other sites More sharing options...
summerinmaine Posted March 23, 2009 Share Posted March 23, 2009 13-13.5 in desert running (20-30mph, 4WD, low range) and 15.5-16 hiway (60-70mph, 2WD), but mine runs cool (~165-175F). Tire pressure @ 38psi and 3.07 gears; other details in my sigline. And mileage is corrected by GPS readings. And I have the camper to increase wind resistance, so I guess I'm not doing too bad. :brows: Link to comment Share on other sites More sharing options...
