well i havent done the governor spring yet, but i would like to know if i did get one, how would my fuel milage be?, what other things can be done to increase the milage a bit? i know the bigger tires dont help all to much but, what do you think?

 

mine is ok in town but awesome on the freeway i havent traveled far enough but the other day i went 270 on a 1/2 tank i usually fuel up when the light comes on that tells me i have 8 gallons left

 

my fuel milage if anything went up a bit i beleive. and its just so much better having the wider fueling range so that i can do more then 65 with my truck screaming!!! gotta love the 727

 

i think the milage stays about the same or goes up if you can keep your foot up, i had this problem. foot kept going to the floor.

 

on a stock 91. how much fuel is in the tank when the low fuel light it on? my fuel guage is out so i fill up around 400km

 

i think 5 gallons but not sure

 

and how far will that get me lol. ive just been ideling around the yard most of the winter. and i havent run it since it came on. but the fuel guage doesnt even work so how do i know if its accurate?

 

at 15 mpg you could go 75 miles or i also read that the engine burns 1 gallon an hour at idle or cost you a little over 1 dollar every 15 min at 4.50 a gal. and if you dont know if its right just go by mileage, if you get 15mpg at you put in 5 gal you could go 75 miles but if you calculate it at 12 mpgs you won't run out if you refill at 60 miles

 

Huh? At 1 gallon / hr don't you mean it would cost $4.50 / hr to run?

I don't think the spring will affect your mpg unless YOU let it. Its just so much easier to romp around with that spring. I try to drive by boost and keep it under 10psi when accelerating and under 5psi rolling. Don't know if that's correct or not but thats what I do.

Try as I may, 400 miles is about the most I can ever get before I have to fill up.

 

1 gallon per hour? Has anyone ever actually checked this with a burette tube of fuel and a stopwatch, should also be 1 quart for 15 minuets, you could divide this down into maybe 5 minuets although it would not be as accurate.

It just seems kind of general because of the differences in idle speed, Auto/ Stick, Torque Converter drag, charging alternator, sloppy injectors.

Has anyone ever tried to cut out 3 cylinders at idle? Cadillac used to have an 8,6,4 design I think was made by Eaton

If you don't drive faster your mileage will stay the same.
