Hello everyone, I'm fairly new around here and considering a '17 3.0TT AWD (low mileage used). I know there are some new owners since this last post, so I was hoping to revive this thread regarding gas mileage. I'm editing this post since I've now read two other threads in different forums about gas mileage being much lower than expected. I don't know about the MKZ's before 2017, but 2017 & 2018 power/torque figures for the 3.0 twin turbo are rated as 350/350 for front wheel drive, and 400/400 for all wheel drive, USING 93 OCTANE GAS. I'm beginning to wonder if the poor mileage figures are due perhaps in part to people using 87 octane gas. I realize that the ECU can have more than one octane rating mapping, but if the engine is designed for 93 octane gas (and has a higher compression ratio and I don't know what other features/factors to maximize output using 93 octane), then while one can run 87 octane gas without knock (pre-ignition), I've read on other forums that one can expect worse gas mileage too. Does anyone know what octane gas that Ford used for the official mileage numbers? So I'm interested in: 1) What year and engine do you have 2) What mpg are you getting (please specify city/highway mix) 3) What grade fuel are you running 4) If you have run 91 octane (or 93 - never seen that where I live though), did you get better mpg than when running 87? 5) If you have run 91 octane, did you feel more power? 6) Has anyone ran their car at a drag strip? If so, what ET and trap speeds did you get? Please say if you were running any aftermarket performance gear (including re-chipped ECU) We've had to loan one of our cars to our student in college, leaving us with only one vehicle, a 2001 Suburban. Not a very inspiring vehicle to drive, plus it gets around 13-15 mpg around town (closer to 13). So I'm looking to get a 2nd car that is comfortable, and that is quicker than average. I'm considering the Kia Stinger GT2, but that's a brand new model and it's not cheap. I'm less worried about residual value as we keep our cars 10-20 years, but there are other reasons to be concerned about the Stinger. I'd also consider a Genesis G80 (or G70 when it comes out). I'd sure like to think I will get 20 mpg around town if I'm driving sensibly. Thank you.

I would like to, that's for sure. I've got to find a low-mileage used one in my area. There are plenty of 2.0T's, and even a few 3.0T AWD's but I also absolutely *must* have adaptive cruise control, which really ought not to be an option on this car - for cyrin' out loud, a 2017 Corolla has it (albeit not down to 0 mph, which drives me crazy)!

Does KBB or Edmunds have a Canadian variant? In the US, Lincoln is offering a bit of cash (hard to fully understand due to not understanding some of the lingo). But what we (US market) do have is a decent selection of used, low mileage 2017 MKZ's (unfortunately though, not many 3.0T AWD versions).

Thank you for the review - I am strongly considering a used 2017 AWD 3.0T. So were you able to get comfortable and did the seats keep you comfortable on your long cruise? I'm guessing so or you would have said something. Thanks again, Jeff

Well, if it's only a 20 hp loss, you're right, I doubt I could feel it. Love that term "butt dyno" :-) Thanks for the info.

Hi, I'm new here, but I used to drag race in the 70's some. What was your trap speed? If I remember from that far back, trap speed is the best indicator of horsepower. I have another question - I live in California and we don't have 93 octane gas. I would love to know what sort of hp and torque to expect on 91 octane. If anyone has any clues (from personal experience or something you read), please speak up.
