chronic139 Posted February 7, 2003 Report Posted February 7, 2003 would anybody with the 3.4 dohc mind telling me what kind of mileage they get. I just want to know how many miles or km you get to a full tank. And possibly the driving conditions that these numbers were achieved. Thanks in advance Quote
lolumz34 Posted February 7, 2003 Report Posted February 7, 2003 Most of the time I get 450-500 Km's a tank when I'm not beating on it. but it's winter right now...and I just put the FFP chip in..so I haven't had the chance to check out what milage is now Quote
Sam96SL Posted February 7, 2003 Report Posted February 7, 2003 You mean to tell me you DOHC guys are only getting 17.5 to 19.5 MPG???????? Seems like quite a penalty for better breathing and higher performance. (I could have estimated this wrong....but seems pretty low to me) Kilometers to Miles-divide by 1.6 Miles to Miles/gallon-divide by 16(tank size) Let me know more on the subject if I've figured this wrong.

DOHCRagtopguy Posted February 7, 2003 Report Posted February 7, 2003 I'm getting a consistent 21-22 MPG out of the Olds running 87 octane regular gas. 80% of my driving is Expressway or Turnpike driving. Quote
patgizz Posted February 7, 2003 Report Posted February 7, 2003 i did a 350 mile drive, about 20 miles was country roads, 50 was single lane mountains, speed limit varied from 35-50, the rest was turnpike 55-70mph with alot of hills. i got 25mpg the whole trip and my torque converter doesnt lock up.

Redfox340 Posted February 7, 2003 Report Posted February 7, 2003 With being in Denver / Fort Collins @ 5200ft. with no modifcations (except wires + drop-in filter) on 85 regular octane I get around 18 city and almost 27 highway... (4T60-E with lockup) Pretty good I think on a 11 year old car with 172K miles... - RedFox340 Quote
SmokesGTP Posted February 8, 2003 Report Posted February 8, 2003 All of my driving is around town and the car usually doesnt get a chance to get to operating temp. I only get about 16. I need new plugs and such though. Anyone else notice their DIC computes the average MPG wrong? Mine says I'm getting 12.8 which I know is way too low. Quote
NORBI Posted February 8, 2003 Report Posted February 8, 2003 When i used to have my 94 CS with 3.4 DOHC, the most i ever did on a tank was 240miles but average was about 200miles, i was little dissapointed in it since the most i did in my Mustang with 4.6 was 320miles on a highway and in the city about 220 but i still think tha CS was better build than Mustang.

chronic139 Posted February 8, 2003 Author Report Posted February 8, 2003 so how would I compute my litres/100km because I really dont like the DIC average that 1 get. would it just be the total km I get to a tank divided by the #of litresin the tank? Quote
chronic139 Posted February 8, 2003 Author Report Posted February 8, 2003 nevermind I figured it out. 13.6l/100km when my Dic is saying 15.4 Quote
mfewtrail Posted February 8, 2003 Report Posted February 8, 2003 me thought gas tank = 18 gallons, or so I read somewhere(owners manual for my 93 GP?)........ Quote
chronic139 Posted February 8, 2003 Author Report Posted February 8, 2003 yeah but im in canad so i work in litres not gallons. I dont know what the conversion is but my tank holds 51-52 litres. Quote
Steve94CutlassConver. Posted February 8, 2003 Report Posted February 8, 2003 my 94 cutlass converible barely gets 16 - 17 mpg , lots of back road driving up and down the hills , I do very good to get 240 out of a tank of 87 oct. but like most others , even with only 53 K miles , its past tune up time ...... the only thing I miss from my Accord was the mileage , 400 per tank !! Steve Quote
STR Posted February 8, 2003 Report Posted February 8, 2003 i get about 300 km per tank in city, 400 km highway Quote
GPRACER Posted February 9, 2003 Report Posted February 9, 2003 Some pretty interesting numbers, I don't have a 3.4, I have the 3100, and it's horrible in the city, aprox 250-270 km per tank. I can usually get, close to 500 on the highway. Quote
SmokesGTP Posted February 9, 2003 Report Posted February 9, 2003 God all this kilometers crap means nothing to me Quote
toastemcutlass Posted February 10, 2003 Report Posted February 10, 2003 hey if you need to ask you cant afford really, they or at least mine sucks on gas milage when I top off the tank, the best I ever got was 250miles and I ran out of gas, but that is town/highway, I never got that again cuz i drive my car hard, so I normaly get 225-230 per tank. I know its not mpg but I'm retarded and don't want to figure it out. Quote
chronic139 Posted February 12, 2003 Author Report Posted February 12, 2003 well anybody in ontario knows that gas is getting very expensive here, so i am on a mission to suck all the mileage i can out of mine. right now im getting almost 400 km in the city. Quote
LowCG Posted February 27, 2003 Report Posted February 27, 2003 I get 22mpg @ 100mph. My DOHC motor is in an old Fiero though ,your results may vary. Quote
ctx46 Posted February 27, 2003 Report Posted February 27, 2003 sh*t.. I got 355 ou of my last tank..... you guys really need to take your foot out of your cars...... 355/14.7g=24.014 MPG with mostly in town driving...... now that my car sits lower to the ground...
