#2537 of 3244 Gas mileage by turbo301 Jun 24, 2005 (5:08 pm)
I was wondering what drivers of late-model CVs and GMs are finding they get in terms of gas mileage. I have been steadily improving mine; even with the A/C going virtually all of the time, combined city/highway (although mostly highway) I'm getting about 23.7 mpg; this week I went 596 km without having to fill up, netting me a cool 26 mpg! These numbers impressed me quite a bit. Although not Toyota Echo territory, I couldn't ask for more from a 4000 lb, V8 sedan that does not feature any sort of cylinder deactivation (thank God ).

I purchased my 2004 CV (LX Sport, dual exhaust, 239 HP) on August 1, 2004...coming up on 1 year, 20,800 miles, so I think I am broken in...have yet to exceed 22 mpg on highway, tried 87, 89, 93 octane, no difference in performance or mpg...kinda disappointed, really...sticker said 17/25, and I personally know of folks with late model Town cars who obtained 27-28 mpg with all highway running...75% of my driving is interstate...AC on or off, no matter...should I trade for a Honda Civic???...

Replying to: marsha7 (Jun 24, 2005 6:35 pm) Hmmm, it is surprising that you haven't been able to get a bit better mileage than that; that's more on par with my '85 GM. Of course, every car is a bit different. It's interesting to know, though, so thanks for replying.   Just me personally, but I would never trade a CV for a Civic . At least up here in Canada, every second car is a Civic!   BTW do you find that the middle portion of your gas tank - i.e. the range from one quarter to three quarters - is your best mileage zone? In other words, I find that the top quarter of the tank seems to get drained very quickly, while the quarter to three quarter range lasts forever.

#2540 of 3244 LX Sport Gas Mileage by jsylvester Jun 24, 2005 (8:38 pm)
I think what is hurting you is the different rear end gearing - 3.27 vs. 2.73 for the LX and Base models. I think that is it, since my 94 has the 3.08 rear end, and it is pulling around 24-25 mpg on the freeway. Also, my understanding is the 03 redesign added weight to the car via a heavier frame.   If you considered swapping rear end gearings, you also have to consider the computer and speedo issues. It can be done, but not sure how much it would cost you. Replies to this message: turbo301 (Jun 25, 2005 2:57 pm)

Replying to: turbo301 (Jun 24, 2005 7:30 pm) As for that range on the gage being the best mileage zone? Nope, it's just the way the gage is calibrated. Most gages are similar. They are meant to provide feedback to the driver as expected, not actually reflect the exact amount of gas in the tank.   One big difference, though. When a General Motors gage first says empty, you usually have about 5 gallons left. When a Ford gage first says empty, you had better find a gas station...and quickly.

Replying to: jsylvester (Jun 24, 2005 8:38 pm) I thought of the rear end ratio, but I don't think with an overdrive transmission it makes that big a difference. My '85 with the handling package had a 3.55 originally, but after its rear disintegrated it was replaced with a 3.08. Gas mileage remained the same.

Replying to: johnclineii (Jun 25, 2005 4:21 am) your experience with GM / Ford gas gauges is the opposite of mine. My '95 Chevy pickup (with its 28 gallon tank) had maybe 2 gallons when the needle touched "E". My '98 Vic though seems to have 4 or 5 left at "E" when the light comes on. And my '90 was even more pessimistic. It would have 6 to 7 gallons at "E". My brother hates riding with me because he's always afraid I'm going to run out of gas...   As for mileage, the first summer I had the '98 (2003), I got 25 hwy constantly. Now I average 22. I did just change the air filter so I'm hoping that'll help. But I've got the Focus for good mileage anyway...

I have suspected the rear for some time, as I do have the higher ratio...but then how does the vehicle get the 17/25 rating, when it is obvious that certain factors have changed, which may directly affect mileage???

Replying to: iusecad (Jun 25, 2005 9:21 pm) Running the gas tank down to almost empty is not a good thing to do for several reasons. Dirt and debris on the bottom of the tank has a greater chance of getting sucked up into your fuel system causing poor performance and clogged fuel passages. Second, your fuel pumps have to work harder to get and move the fuel. Some in-tank fuel pumps use the fuel to help keep them cool. So not only do you risk clogging up the fuel system, but the fuel pumps are more susceptible to early life failure from being more stressed and over heated. I usually don't go much below a half tank before filling up. You also don't feel as much pain at the pump if you fill up from a half tank versus filling up from empty. I know it's a psychological thing, but it does help ease the pain at the pump a bit. Replies to this message: turbo301 (Jun 28, 2005 8:54 am) iusecad (Jun 28, 2005 9:19 am)
