I have an extremely steady foot. I can keep the speed far more steady than cruise control can. I don't like to use it infact because of the fact that the CC lets on and off of the gas constantly. This will hurt your MPG right there. I tend to have a light foot as well which helps. Also, I let off the gas around half a mile before I start to apply my brakes. coasting will significantly increase your gas mileage. Think about it, with your foot off the gas, you're getting right around 100 MPG because you're only using enough fuel for the engine to idle, not to put out power to keep teh car moving. In this effect, your car will be getting this 100 MPG for half a mile. Over time this can make a big difference in your gas mileage. Just go easy on the gas padal, and easy on the brakes at the same time.

I think you'll find that the modded SSEi'* all get better mileage.

As long as you keep your foot out of it.

I live with cruise control because even light pressure sends the car scurrying ahead. I see about 28-32 hwy at about 75. in town is much less because I love to stomp Iwhatever car is next to me.

I got 29 mpg on my trip down to chicago this week. Normally get between 25 and 26 mpg. Wonder if the cooler weather is a factor?

In my old 1999 SSEi the best I ever got was 31 mpg. Typically though I was seeing 24-26mpg.
One thing about Michigan -the gas there is considerably better than here in MN, which may contribute to the high window sticker MPG'* as Michigan is where the majority of the test'* are done. When Seth, Jason and I were heading up to Mississauga, ON in March Jason got 40 mpg in his 1993 Bonneville SLE (L27 3.06 axle ratio), and Seth got 41 mpg in his 1998 Bonneville SLE (L36 3.05 axle ratio).

So far in my 1998 SSE (L36 3.05 axle ratio) I have managed 30 mpg and with a CEL ( o2 sensor and another new code -unknown as of right now) I was still able to average 27.5 mpg on a freeway trip with 4 passengers (me being the lightest at 145 lbs). Now with a new o2 sensor I haven't checked the mpg'* yet, but the car idles noticably better and the gas guage isn't moving quite as fast.
And after Friday when I have my 3" down-pipe, 2.5" high flow Magnaflow cat, and 3" Magnaflow Wide Open muffler I should be able to get another 1-2 mpg on the freeway.

I just got 500 miles on one tank this week cruising between 65-80 with part of the trip through the mountains. I was really trusting the "miles remaining" on the DIC, cause I got it down to about 50 miles left b4 I refueled.

Now that'* something I find hard to believe. I get at most 410 miles to a tank when I get my absolute top 25.2 mpg'*. At 500 miles to a tank that would be? 35mpgs??? Naaaaa

Not to hijack this thread as it is on topic but how far has anyone gone with the fuel light on? The furthest for me is 45 miles accross a mountain pass, bit nervous and kept it below 70mph.
Gas stations can be few and far between up here.

I thought it was a 2 gallon reserve, but the most i've been is about 25 miles.
