Gas milage October 28, 2004, 07:10:29 PM What kind of gas mileage does everyone get? I have an 87 Cougar with a 3.8 and i get and average of 24.7 . That is even after adding a newer y-pipe with only one cat and dual exhaust. It only helped a little bit I used to get about 23 before. Quote Selected

Re: Gas milage Reply #2 – October 28, 2004, 08:03:22 PM last month: driving fast on entire tank- 14.7, slow - 14.8, all city driving - 8 miles with like 25 stoplights daily. Obviously it needs to be fixed but the weather got nasty quickly. Runs flawless but there has to be a problem somewhere :( Last time i drove up to seattle, I was around 30mpg at 70-80mph entire trip minus Tacoma traffic and lowered speed limit.5.0SO AOD Quote Selected
Re: Gas milage Reply #3 – October 28, 2004, 08:17:34 PM I thought my gas mileage was a little off. Now i drive very conservativly cause if i drive like i used to then i get like 17-18. My check engine light as been on for a little while, I think is the o2 sensors they are original and my car has about 165,000 miles. I picked some up a few days ago but haven't had a chance to change them yet. At least it can't hurt to change them if that isn't it. Quote Selected
Re: Gas milage Reply #4 – October 28, 2004, 08:39:35 PM After tuning up and a few minor mods my past 2 fill ups have gotten me 350 and 380 miles per tank respectively. I think it was around 18-19mpg city. On a recent trip to columbus, i think i used 3 maybe 4 gallons for a 160ish mile trip (between 35-40mpg) Quote Selected
Re: Gas milage Reply #5 – October 28, 2004, 09:12:19 PM I'm averaging around 26mpg, mostly in the 50-60 mph range. Quote Selected
Re: Gas milage Reply #6 – October 28, 2004, 10:10:59 PM In heavy city and rush hour traffic like having to wait at every light for 3-5 cycles before getting thru I get 13-15. Real open road zero traffic 30. Typical mixing it up 19-22 Quote Selected
Re: Gas milage Reply #7 – October 29, 2004, 01:21:54 AM Around town my '87 5.0 gets about 19mpg. On a highway trip I usually see around 25. Not too bad, IMO. Quote Selected
