just curious have u tried any runs w/o ur clutch fan yet?

i'm all for the scientific experiment but when you are dealing w/ diffrences as small as .5-1.0 mpg you have to be more accurate than one mpg or two.
i understand u can't fill ur tank for every run and use the odemeter. thats insane
the only way u could do that is with a small 1gal auxillary tank.
sounds hard but i saw it on mythbusters you might want to check their site out.

 

Yeah, that's just too much work, I am doing my best to find days that are similar to run my test. it has been raining all week and I can't get a good test.

 

Well, the gas mileage test won't be done for a little bit, we drove another car instead of the truck for that 6 hour drive. I'll post about it later.

 

i drove 140 highway miles on saturday. with odom i got 15.5 mpg overhead was 13.3. i was going at about 80 most of the way. not babying the throttle at all. take what you want from that.

 

So the overhead was less... I like where this is going...

 

yea but a few weeks ago i did a odom reading for city driving, overhead was 13.3 actual was 10

 

how often are u resetting the computer, if u havent its prolly still a ton of tanks back
thats the way my old lebaron was

 

Is your speedo calibrated right?

 

its been a while. but when i drive back i will reset it.
