ScoobyDoo82 Posted October 16, 2010 Report Share Posted October 16, 2010 I was just wondering what some of you guys are getting in your w's as far as fuel economy goes. My Grand Prix has me stumped, I thought I broke the float in it or something because the gas gauge didnt move until 65 miles later. I'm at 80 miles now and still 13/14 ticks. If I'm thinking correctly, theres 14 ticks for 16 gallons of gas which is a little over a gallon per tick. Even if it were 2 gallons per tick, that would mean I'm still averaging 33MPG, and that doesnt make much sense to me . Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted October 16, 2010 Report Share Posted October 16, 2010 the guages aren't very accurate, especially when near full. i have managed 35MPG in the MC and just over 30 in the GP regularly if i accelerate like i have nowhere to be...

ScoobyDoo82 Posted October 16, 2010 Author Report Share Posted October 16, 2010 For a minute I thought I broke the float filling it too high, mile after mile and the gauge wasnt moving . That would be kick-ass if I'm doing that. Ive been getting low-20s in my 3.1 Cavalier, needless to say high MPGs would be a nice change .

carkhz316 Posted October 16, 2010 Report Share Posted October 16, 2010 My old 91 Euro Lumina would net me 29.5 mpg doing ~70mph commuting back and forth from school. Drove the '92 Z most of this summer to work and back (approximately 6 miles) with a mix of city driving, which netted a combined 20 mpg. I bested 31.9-32 mpg in my 98 Monte Z34 in it's pre-topswap; L36 trim. Quote Link to comment Share on other sites More sharing options...
gpchris Posted October 16, 2010 Report Share Posted October 16, 2010 Mine shows 35mpg at 73mph. I think that's pretty impressive for a 15 year old family car. Proof: Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted October 16, 2010 Report Share Posted October 16, 2010 that with the 5 speed? Quote Link to comment Share on other sites More sharing options...
1tinindian Posted October 19, 2010 Report Share Posted October 19, 2010 Instant fuel mileage isn't very realistic. My 95 GTP 3.4 just got an overall averge of 28.8 on a 200 mile round trip this past weekend. Not bad for a car this old with 167000 miles. I was happy with it!

GOT2B GM Posted October 19, 2010 Report Share Posted October 19, 2010 Did a 300 km round trip today in my TGP. Didn't baby it at all. Mostly highway, some stop and go in Toronto, some 150 km/h cruising. Mostly 120-130 km/h. 25 MPG average. Quote Link to comment Share on other sites More sharing options...
mfewtrail Posted October 19, 2010 Report Share Posted October 19, 2010 I average in the very high 20's in my 3.1 cars with a mix of about 85% highway & 15% city driving. With all highway driving, I've averaged 34-35mpg several times over a full tank of gas(on road trips, the roads were very long + flat leading to South Georgia).

Crazy K Posted October 19, 2010 Report Share Posted October 19, 2010 I average in the very high 20's in my 3.1 cars with a mix of about 85% highway & 15% city driving. With all highway driving, I've averaged 34-35mpg several times over a full tank of gas(on road trips, the roads were very long + flat leading to South Georgia). Would it be safe to assume you were going downhill? I remember getting 34-35 in a 3.1 mpfi when coming down from the Appalachians to the east coast....

Addicted To Boost Posted October 19, 2010 Report Share Posted October 19, 2010 I averaged 31 MPG on the one highway trip I took my TGP on. My old blue 91 SE regularly got 30 MPG with a mix of city and mostly highway. We'll see what the 88 gets now... It averaged 34 MPG on the way home from the previous owner's place, mostly 55-60 MPH driving. Quote Link to comment Share on other sites More sharing options...
white4d96 Posted October 19, 2010 Report Share Posted October 19, 2010 Ugh you guys suck! My 3100 SE get's 18-20, 1/3 highway and 2/3 city. I can crack 21 if I try really really hard. What do you guys recommend to get the mileage up? Quote Link to comment Share on other sites More sharing options...
Addicted To Boost Posted October 19, 2010 Report Share Posted October 19, 2010 ...and for what its worth, I could only get 22 MPG with mostly city driving in the TGP That was driving it pretty nice too. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted October 19, 2010 Report Share Posted October 19, 2010 for fairly heavy cars, such as a W, city mileage will always suck isnce you're constantly bring a shitton of mass from low or no speeds up to the speed limit at the rate of everyone trying to run your ass over.

GnatGoSplat Posted October 19, 2010 Report Share Posted October 19, 2010 I only get 18mpg, but I think that's because my car is so slow, it's always in a constant state of accelerating. Quote Link to comment Share on other sites More sharing options...
