Holla Holla at 9 MPG

 

My best was either 21.xx or 24.xx mpg's on a straight shot from gas station to gas station on a trip from Manheim, PA to Altoona, PA using the methods described in the OP.

2000, 4.3L, 3.42's, AUTO, 4WD, 2DR, all highway, cruise set at 70 on PA turnpike for approx. 180 miles on a warm Spring day. Don't know if this is fair because I didn't use a full tank.

My average now is right around 17-18 mpg's with the same truck, 235/75/15's (instead of stock 235/70's which also messes with odometer), with winter mix fuel and a homemade shielded CAI. Drive is probably a good 50/50 mix as I have to drive from town to town to work in various homes and schools.

Hoping to see that number stay at 18-20 once winter mix is done.

 

I get anywhere from 15-17

stock everything with 3.42 gears
about 60% highway/40% city
outside temps= 26 to 40 right now

i think you should have waited longer until winter grade gas stops

 

I have been checking mine at almost every fill up since I got the Truck and basically sit right at 18.3 almost every time. Then I changed the fuel filter and it dropped down to 17 about every time. But could have to do more with the plugs/wires since I don't know how old they are. Still need to do a leak test to make sure everything is fitting right.

 

16.6 MPG on my last highway trip without my brushguard...

I'll actually vote in the poll when my new engine is broken in and I don't have to keep going from 60 - 75 MPH...

It'll get better when I can drive at a steady RPM

 

I get about 15mpg. 1996 Blazer lt 4x4, 4-door, 4.3L,3.42. Should have a tune and 4.10 in the next two weeks so I'll update. Mods are in sign.

 

I am averaging 16-17 currently at the moment, city driving, easy on the throttle but have an exhaust leak that is holding me around 16-17 mpg at the moment plus I need to do a tune up! I have a cold air intake for performance mods and that is it. Otherwise stock gears with 18 inch chrome rims and 225/40r18 for tires , 4.3 vortec v6 2dr 2wd!!

 

im glad we finally got a poll on this, hopefully no more topics of the mpg

 

getting around 17-18 mpUSg which is around 21.5 per UKg

currently Gasoline is about £1.05 per litre so around £4.20 per USgal

Current exchange rates make that about $8.38 USD per USgal

also seem to have a higher octaine rating than you guys: 95 for regular, 97 for super (occasionaly 99 super at some stations)

 

I average between 17.6 and 19.1 mpg depending on traffic on the interstate. Usually easy on the gas, running regular. 99' 4.3L,4x4 4door, 3.73's...(most tanks run me 18.7-19.1) 70% highway-30% city
