Okay guys, here are the results of test 2 and 3.

Test #2 - 10 Gallons @ 155.8 miles in town = 15.6 mpg city

Test #3 - 1 Gallon @ 22.9 miles on the loop with tailgate down= 23 mpg HWY tailgate down.

Next test will be 1 gallon on highway with tailgate up.

 

around 11 mixed driving out of my 95 5.8 W/ 308 REAR

 

Thanks for all the testing man, I'm getting about 11 with 3/4 city and 1/4 hwy driving with my 5.0. Had a bad O2 sensor which helped a little, though I haven't actually tested to see if it is failing or not. I have heard you can't even trust the idiot light at times. Any results would be great, though I suppose I could be due for an oil change here soon. Later.

 

Test #! - 10 gallons @ 155.1 miles = 15.5 mpg city.

Test #2 - 10 Gallons @ 155.8 miles in town = 15.6 mpg city

Test #3 - 1 Gallon @ 22.9 miles on the loop with tailgate down= 23 mpg HWY tailgate down.

Test #4 - 1 Gallon @ 22.1 miles on the loop with tailgate up= 22 mpg HWY tailgate up.

After replacing a bad Pinion bearing and u-joints I retested #3 and #4 although I still need a front end alignment.

Test #5 - 1 Gallon @ 26.1 miles on the loop with tailgate down= 26 mpg HWY tailgate down.

Test #6 - 1 Gallon @ 23.9 miles on the loop with tailgate down= 24 mpg HWY tailgate up.


So as of now the mileage stands at 15.5 city and averaged 25 highway.

 

thats pretty good

i just did a tune up to my beasty and shes running better i think i can get close to 350 km to 60L now!

i think thats like 14 mpg somewhere close to that so that sounds right!
