GPdriver1986 Posted October 31, 2005 Report Share Posted October 31, 2005 I have read the numbers on fueleconomy.gov for the Grand Prixs (97-current) 3100 and 3800 n/a but they aren't always accurate. I need to know what you guys are getting with these 2 engines, tell me if you drive in the city/highway and how much per tank? Whats the tank size anyways? Thanks.

94CutlassSLCoupe Posted October 31, 2005 Report Share Posted October 31, 2005 I have driven my mom's 1997 Pontiac Grand Prix GT with the 3800 Series II, and with an average of 70mph on the highway i was able to get 31.7mpg (trip computer was reading 32.9)...It was some crazy thing like over 450mi on that tank. In the city we've found it gets about 19 and it gets about 23 in mixed driving. Overall, its a great car for fuel economy, IMHO Quote Link to comment Share on other sites More sharing options...
manitcor Posted October 31, 2005 Report Share Posted October 31, 2005 most w-bodies regaurdless of engine tend to do 25-30mpg on the highway and 19-25 city Quote Link to comment Share on other sites More sharing options...
94CutlassSLCoupe Posted October 31, 2005 Report Share Posted October 31, 2005 yeah that's true...unless its a quad 4 dohc with the 5-speed...lol that thing gets 35 hwy without trying Quote Link to comment Share on other sites More sharing options...
THe_DeTAiL3R Posted October 31, 2005 Report Share Posted October 31, 2005 What those guys said sounds accurate, and similar to what I get with my car. They all have approx 60L tank capacity. Quote Link to comment Share on other sites More sharing options...
Dannymik Posted October 31, 2005 Report Share Posted October 31, 2005 i get an average of 25-27 mpg with mixed driving in my '02 GP Quote Link to comment Share on other sites More sharing options...
THe_DeTAiL3R Posted October 31, 2005 Report Share Posted October 31, 2005 i get an average of 25-27 mpg with mixed driving in my '02 GP Really? Damn... On my drive to work (short trip lots of stop and go) I only get like 15mpg... shitty. Driving around town with some mixed country/highway I get 23mph mixed. Country/highway I get 30-39mph depending on the speed and weather conditions. Quote Link to comment Share on other sites More sharing options...
runt Posted October 31, 2005 Report Share Posted October 31, 2005 My '01 gets 24-26 with mild city/mild open road driving. On the highway I get over 30 no problem. I've seen over 400 miles per tank at least twice on some of my bigger road trips. Normally I get around 305-330 before I gotta gas up again.

Country/highway I get 30-39mph depending on the speed and weather conditions. Yup. Although i'm not the 3800, I see the same thing. City is like 15-17... and highway sees 30-34. Mixed, I don't know.

GPdriver1986 Posted November 1, 2005 Author Report Share Posted November 1, 2005 of course this is without pushing hard on the accelerator Quote Link to comment Share on other sites More sharing options...
THe_DeTAiL3R Posted November 1, 2005 Report Share Posted November 1, 2005 Well I gotta push my 3100 harder (like up to 3000rpm normal acceleration) than a 3800. Those are nice to drive in the city, light throttle and they go. Quote Link to comment Share on other sites More sharing options...
Burnout524 Posted November 1, 2005 Report Share Posted November 1, 2005 Geeze...thats pretty good. I've kept a log of my gas milage, it ranges from 13.2 to 19.7 MPG. My last tank took me ~220 miles or 16.6 miles per gallon. Keep in mind, that A) I'd be lucky if I get 5 highway miles on a tank and I'm driving an Intrigue, although the same engine (3800 series II), the cars/weights/etc are a little different. Hopefully when I get some money, I can buy a K&N drop in and maybe boost my gas milage a little. Quote Link to comment Share on other sites More sharing options...

THe_DeTAiL3R Posted November 1, 2005 Report Share Posted November 1, 2005 I get anywhere from 230miles (all city stop-and-go 15mpg) to 350+miles per tank (highway). W-bodys can be great highway cars, but mediocre city cars no matter what... Quote Link to comment Share on other sites More sharing options...

THe_DeTAiL3R Posted November 1, 2005 Report Share Posted November 1, 2005 A Canadian made the thread! I can convert speed in my head but not volume. I have no idea how many L is in a galon or whatever. Quote Link to comment Share on other sites More sharing options...
