will TOD disconnect improve MPG?

[SGT.BATGUANO]

530 km = 329 mi

85 L =22.5 gal

76L = 20gal

So you're getting 14.5 or 16.5 mpg before tire correction

Oh well, I was pleased to get 530ks with the light going on...and in view of fuel efficiency [lack] ..I am glad Isuzu fitted the capacity fuel tank [larger] that they did to give a half decent touring range.

...hmm..I'll recheck my numbers again, my fuel calculator is a bit old [slide rule type]...but doing the simple divisions on the above 76L/530kms = 14.3L/100kms which is [on reflection] up there with the bigger 6 cylinder 4wds, in our market [Prado/Harrier/Montero]...

Will fuel/oil ever get back to under $50US a barrel..$66 today !!

Sounds like its not worth the effort then, thanks for the input though, i didi put fuel system cleaner through there a couple of months ago but it didnt make any difference, i replaced the pcv valve too and have a K and N filter on it, i dont drive it too hard but have had the AC on pretty much all the time for the last few months...gets pretty humid here in Minnesota!

Ohhh well, like i bought the car for its fuel economy right? hah hah!
