I usually get 415km or 260 miles per tank. I guess that isn't too bad considering it is ALL city driving, and I driver her hard.

This tank I got 336km or 210 miles. I hope it isn't a problem with the car. This tank of gas was from an Esso station. My normal 415km tanks are from Shell. I really hope that is the difference.

Any paticular stations you guys get the best mileage off of?

we i couldnt tell you of one being better then others, however i have heard of complaints of PeterCanada, and i dont know how far spread this one is but Beaver gas stations suck bigtime!! i had the worst proformance iout of a tank of that **** thn anything else

When was last time you changed air filter, tune up, changed 02 sensor

uh yeah thats 15 miles per gallon

I usually never get worse than 20mpg and thats mainly never above 40mph. Usually it gets to 1/4 tank or so at 300 miles (however thats when 16 gallons is used), before my o2 sensor and I replaced a bunch of sensors/other tuneup items it was about what you are getting. high flow cat also helped a lot.


29mpg highways is what it gets at 82 on cruise control. my last car would do over 30 on straight highway but really man do the tune up items, at least o2 and cat, it has a serious effect on these cars.

wow, i just did 385 miles on my last tank...yeah like said b4, check the most obvious, plugs, o2, filter, and maybe check the amount of lead on your foot

i'm thinking the same thing

Well, it'* more like 16mpg because it was only 62L and not the full 68L. And I though these things were supposed to get 17mpg all city, so I figured it was just my driving habits.

Filter is fine, just did CAI. I think I will do the plugs this weekend...maybe the O2 as well.

Well I usually use Esso gas in my car. I have found that I usually get great mileage from Canadian Tire gas. I did use shell for a bit, but shortly after using it, I lost my fuel sensor, so I could not tell how much gas was in the car. I did a bit of research and found out it was a common problem with Shell and I think Petro Canada. I have heard that the worst gas to use ( dirtiest) is Petro-Canada.

I usually try to stick to one company for gas since I find switching from one to another is just problems for the car.

My last Bonneville at the worst got 220 miles a tank. At most it got around 270-280, with a lot of city driving, and that came after fuel system cleaner.

With this one I average 700kms a tank with 90% highway driving, and use a lot of different gas stations each with 10% ethanol. I used to get less than 700 but after adding complete fuel system cleaner I gained a lot of mileage and performance.

i average 400 miles on a tank. city/hwy mixed. of course, i have a 20 gallon tank so...
