Ah, yes. Let me just state that i'm not upset with the "cost" of my perceived high consumption. If the point of this would be cost reduction then I would be in a Toyota or something. No, what upsets me, is that I keep reading posts like yours where guys are running 7~8L/100km driving "normally" with a mix of hwy/city. That makes me think there is something wrong with my car only getting 12-13L/100km. I'm trying to see if anyone has ever come across a setting, part or combination of which would have caused their high consumption. Seeing as I have no cel or codes, i'm doing research on the possible causes.

With regards to the fuel octane; if manufacturers bother labeling requirements on their cars, I think fuel resellers should have a number posted at the point of sale, no? What the hell is "clean" "super clean" and "supreme clean"?! I run the latter which I assume is 91 and the car pulls timing at anything over closed throttle! So, is it 91 or not? I will try regular next time to see what kind of logs I get.

You see, I just have an unfortunate OCD thing that won't let me live until an engine runs how it should...

Absolutely! I just want to know that when I floor it, it's getting full boost, full timing and not messing around holding power back because of bad fuel, iffy sensors, and leaking connections causing it to run ghetto rich.

Have you thought about a ECU flash? The reason I ask is that when I bought my 2 yr old Avant I had a issue with engine surge under light throttle application at low RPM's on the hi way. Unrelatedly when I had a stage 1 oil consumption test done - cured the problem totally BTW - part of the test was a ECU re flash. That fixed my surge problem totally as well.... so, who knows?

I have taken your advise and ran a test on my last trip to Montreal and my MMI and the fuel pump filled up versus millage are so closed that I will reiterate my last statement. I am still at 7.6-7.8 fuel consumption. I have been very diligent when fuelling and highway rating on 401 at 120 km gives me 7.6 average the same as MMI. One thing I will give you, I did not tried with 91 octane or higher. The performance for highway driving does not require high octane performance so I did stick to 89 octane.
I can't explain why some people have much higher rating, does it have to do with the way they drive, accelerate, etc...
And Yes saving money should be a goal to everyone if the performance is not a requirement I don't see why you should make the petroleum company richer. Also all fuel are much cleaner today than they used to be, they also all contains clean up agent.

After reading some post, I have to say that I am really happy about this car and even though I was contemplating to changed to a newer model I think I will stick to it a bit longer because it is giving a very good millage.
