just curious what's your fuel economy. I get 16-18mpg city driving and 26 on highway. And I have a feather foot! Edited by: oldnew

with the same car 20mpg in town! Most likely the traffic is light where you're driving. To me, it takes 15-20 minutes to goto work and40-60minutes to return. A lot of stop'n'go and idling on the return path. Plus a hill I have to climb both ways. thanks |
yes traffic is light and i use hi octane gas. 20mpg is in summer too.
in winter it's less. |
I'm not sure what I get during everyday driving, but on highway trips, I've gotten as high as 28.7 and as low as 22mpg. If I can keep the cruise on 75 or 80, I'll see 28 or more, no problem. When I set it above 85 or 90 (az desert highway between Phoenix and CA), I was only getting 22 or so. CJ |
not shure my 3.8 only run WFO ( wide F#$%King open ) [img]smileys/smiley2.gif[/img]

For a couple of years ago I own A 1987 century stationwagon with the 3,8 engine and I was really surprise every time i will fill it up with gas, never less than 22-23 MPG with a lot of city-driving. Now I own a 1995 Cadillac DeVille with the 4,9 engine and this will have 18 MPG at the same driving. I have look at A 1999 Park Avenue Ultra, My question is if this supercharged enginewill have much more fuel than the old 3,8 without compressor or can I drive It at 22-23 MPG like the Century. (50% city 50% Highway) |
My wife drives a 99 Regal and gets around 22 city and averages around 28 highway.

I have a '97 Ultra (Supercharged). It is my second; first purchased new and sold at ~260,000 miles. I still see it driving around the neighborhood. I think you will like the SC engine. You can get very good economy if you drive nice, and still have a car that is very fast when you want it to be. One small downside is that you are supposed to use 91 octane fuel. However, I don't believe you will do any damage using regular because the engine computer will retard the timing at incipient knock. Particularly during winter, I often use regular and have seen no problems. PS: Keep in mind that the Park Avenue is a larger car, and even with the same engine, is not likely to achieve the same mileage. Edited by: MrBSS |
Regal 1995 in Holland: 50% highway (max speed 75 mph) and 50 % city driving, she is doing fine at 25 mpg. At least better than BMW 3.4 egine in 735i that was using 21 mpg with same usage... |
I also have a 99 regal, but it only averages 25 in the highway! |

I have a 1996 Regal 2 door Gran Sport. Just coming back from a 300 mile trip (usually driving about 120 kmh, or 75 mph) I did 29 mpg. Quite pleased.

i have a 98 and i get 17 city and about 20 on the highway with a rather "spirited" driving style lol
|
I get about 16 or 17 in the city and have gotten 32 on the highway using cruise at 62mph a couple of times in my GS.

PS: Keep in mind that the Park Avenue is a larger car, and even with the same engine, is not likely to achieve the same mileage. but on the regular gas, thats just wrong. you should ALWAYS run premium on the L67s. with the L27s and the L36s, regular is fine and premium is just unnecessary. and yes, the pcm will detect kock, and retatd the timing, but it cant do that untill AFTER the knock occurs. thats badEdited by: samueljackson |
Just measured on my 1996 Custom 3.8l = 21.7 mpg in mixed driving.

1995 Regal (4dr 3.8 L) Just got 23.1 MPG with mixed driving. [img]smileys/smiley1.gif[/img]
