pitzel Posted September 15, 2004 Report Share Posted September 15, 2004 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? Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted September 15, 2004 Report Share Posted September 15, 2004 Not a Cutlass but I have got as high as 34 on my TGP. That's on interstate with the cruise set at 72. Quote Link to comment Share on other sites More sharing options...

Justin Posted September 15, 2004 Report Share Posted September 15, 2004 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. Quote Link to comment Share on other sites More sharing options...

tloftus Posted September 15, 2004 Report Share Posted September 15, 2004 I think the one in my 89 Cutlass tops out at 80MPG which I got coasting in neutral down a big hill. Tom Quote Link to comment Share on other sites More sharing options...

digitaloutsider Posted September 15, 2004 Report Share Posted September 15, 2004 I get 99 MPG just cruising down the highway (no accelerator). I do it all the time. No neutral needed Quote Link to comment Share on other sites More sharing options...
99RegalGS Posted September 15, 2004 Report Share Posted September 15, 2004 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 Quote Link to comment Share on other sites More sharing options...
TeeJay3800 Posted September 15, 2004 Report Share Posted September 15, 2004 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? In "Instant" mode, I've seen a steady 33 MPG at 60MPH/1900 RPM. I think the one in my 89 Cutlass tops out at 80MPG which I got coasting in neutral down a big hill. 80 is the highest that the CS DIS reads.

Baddflash Posted September 16, 2004 Report Share Posted September 16, 2004 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. Quote Link to comment Share on other sites More sharing options...
