DIS/DIC owners -- highest MPG

[pitzel]

Hi. For those who have the DIC/DIS on a Cutlass Supreme 3.1, whats the highest MPG reading you've gotten, on straight and level flat road, and at what speed?

Not a Cutlass but I have got as high as 34 on my TGP. That's on interstate with the cruise set at 72.

I've had 34mpg on the gtp.

I've gotten an honest 34 on highway, I believe the cruise was set at 72. I've been as high as 43 with a mean tailwind.

I think the one in my 89 Cutlass tops out at 80MPG which I got coasting in neutral down a big hill.

I get 99 MPG just cruising down the highway (no accelerator). I do it all the time. No neutral needed

I've gotten 32.6 MPG on my DIS on a trip doing about 65mph and going through Chicago, wich was slower. But when I filled up and averaged it I actually got 24mpg. lol

In "Instant" mode, I've seen a steady 33 MPG at 60MPH/1900 RPM.

80 is the highest that the CS DIS reads.

The avg really depends on how I drive, damn 5-speed is always eating up my gas! Also most of my driving is in town so I avg 18.X mpg, cruising at 65mph it usually pulls 34-36 mpg. My STE DIC tops out at 99 mpg.
