I used to use 87, but found that the car does not feel nearly as sluggish with 89, so that is what I have been using.

As far as MPG, I used to average about 27-29 with mixed driving. Once I started having to drive a decent bit to work, my mileage started averaging about 32.

I had never had the car on a long trip until my graduation in late May. Since I had moved back to East TN to finish my clinical rotations, I had to head back to West TN for graduation. I thought I'd be smart and reset the ECU so that I would have a true picture. Maybe that was not such a good idea. Well, driving to Memphis avg about 72 MPH, I only got 30.3. I was so dissapointed. However, on the way back (usually always worse from other trips back home for holidays in other vehicles) I got 36.8!

Now that my car has some miles on it (just turned 18,000 coming back from Orlando on vacation Sunday), I got 38 on the dot going from Knoxville to South GA, but only 35.4 coming back from Orlando to Atlanta. I topped it off about 20 minutes outside of Atlanta, and drove roughly 160 miles of flat interstate back to Knoxville, and decided to top it off one last time once home, and to my astonishment, a new record! 39.4!! I was really happy with that.

Oops, I usually use one of our local (E. TN) convience stores (Weigels). If not those, I go with racetrack, or whoever has the cheapest 89.

I get about 24.5 MPG in city driving using 87 octane gas. I basically get whatever is cheapest so it's usually Dodge's, Albertson's, Raceway, or Wal-Mart.

On road trips to and from Miami I always check my gas mileage and I get about 32 MPG going about 75 MPH. If I drop the speed to 55-about 65 I go to about 35 MPG

BP, 87, 26/31 don't do much city driving so 26 isn't a solid average and hw is 31mpg but when driving 65-70mph i've averaged 34-35. can't wait to see what the CAI is gonna do to these numbers

[QUOTE=jameswing]Please post where you fill up, What Octane, and your MPG

1) anywhere where a membership card knocks a few cents off (Sam's Club, Kroger, etc.)
2) I have run 87 since I bought the car.
3) about 31 mpg, 60 miles a day commute, mostly 2 lane, so I pass quite a bit.

I've only checked my mileage once since I got the car and it was a few weeks ago:

Where? Whatever's handy, usually a Noco or a Pioneer though
87 octane
20mpg (converted to American gallons)
That's due to full throttle starts and 90mph commuting though.

Where? Cheapest (usually certified) 87
MPG? @27 90% 45mph city/street

Got 36mpg in the wifes last weekend on a 4hr trip.

BP/Amoco 87 octane. Avg 25-28 Mpg, with 90% city/town driving and a very heavy foot.

I selected 92 octane, but it is whatever is the highest at the pump (not including 100 octane racing fuel). Sometimes it is 91, 92, or 93 depending on where it is.

I fill up wherever I am so different places but if I have a choice, I will pick a Chevron for two reasons. First reason is i know they have good gas but in all honesty, that isn't the main reason. The main reason as odd as it sounds is because every Chevron I have ever been too, has free air. Yup, free air. I don't feel any service station should charge you to fill your tires up even if it is just $.25 (although I have seen some as high as $.75). It isn't because I am cheap either, it is more just the principal and the fact I usually don't have a quarter on me at the time. Also, the free air usually pumps faster.

I get about 20mpg in the city. The mods I have the affect the fuel the most is an intake and 61mm BBTB and drive it like I stole it.

On the highway, I get about 28-29mpg

Steve

Canada has L/100km, so Jo is burning 8.9L/100km or 26mpg (American gallons) or 31mpg for Canadians, we use the British gallon which is 4.54quarts instead of 4.

Cheap (not cheapest, not am/pm or anything I hadn't heard of) cobblestone/costco/sam's in AZ, or sometimes shell when in Cali - 87 always, atleast 30mpg. I noticed years ago that my mileage sucked w/ a higher octane.

shell 87 28.8 aggressive ( never shift under 4 grand unless traffic, 5th only on the highway)

87 usually QuickTrip or Sams. Been getting 33.4 the last 3 times I filled up no matter how much highway/city driving or if I'm trying to continuously keep up with a mustang or two.

Wait a sec.....26...that's bad right.....

Steve
08-19-2004, 03:42 PM
26 is in those funny little American gallons Jo, you should pay attention to the 31mpg number, that's based on the Canadian/British gallon.

cheapest place in town (usually the local full serve gulf station) 87 and lookey here.... 20mpg.. lol 8 mile commute (roundtrip) to work... heavy foot in an automatic... I get around 240 miles to the tank usually....

Cheap, 87, 27/31
Here in Portland, highway driving is almost as bad as city driving at the wrong time of day, which is when I'm usually on the road. I've cracked 32 on road trips, and after removing my intake resonator I seem to get another 1-1.5mpg.

How many miles to a tank then?

I've never added it up. Maybe I will next time.

XTRAWLD
08-19-2004, 06:34 PM
KM's to a tank usually 550.....just to add more confusion.

SWortham
08-19-2004, 07:08 PM
And I guess I should account for the slight speedo / odometer miscalibration due to my oversized tires. :)

Jlivan
08-19-2004, 08:22 PM
Cheveron 89, or shell 89. Sometimes I slip and buy walmart/Murphy 89. It was only a couple of times...it won't happen again.....I promise.

87 BJ's Wholesale Club

I'm only on my 3rd tank of gas. I just put 89 (Getty) to see if there is any mileage difference.

BTW, what diff does it matter where one buys gas? Isn't it a commodity?
