Four our 1st tank on our new 300h we are getting right at 27.7 MPG, but it has been cold and snowy here near Chicago so that hasn't helped with the mpg at all.

Just passed my 1000 miles mark in and around Raleigh, NC. Basically averaging only 29 mpg. Do notice a real decline when I use the heater which has been most of the time. Hope when warmer weather comes around and the gas blends change that I can get the average of 32 mpg. Think I will. By the way I have had a 2014 CT200h for 10 months and know well how to take it easy and so call glide down hills, etc. If you take your time and drive the speed limit without quick starts then you should get good mileage. I have a front wheel drive NX300.

for those posting your numbers can you also list which NX you own. I am able to guess based on the results who has the hybrid vs regular engine but a guess is just that.

I am guessing those in the 22-25 mpg range have the regular engine while those over 27 have the hybrid. Of course those who drive mostly highway may get 27 mpg in the regular engine.

I passed 3000 miles this past week and have been getting an average of about 25 MPG. My driving is currently a weekly 500-mile round-trip commute (at 70-80 MPH) and then errands around town. I'm pleased with the mileage I've been getting.

I have an F-Sport and I'm getting just under 20mpg. That's doing 90% city driving / 10% highway.

Also, are you calculating your gas on your own, or trusting the on board computer? We need real world mpg's, which means not looking at the screen, and trusting what it says.

I keep a spreadsheet at home, where I record miles driven and gallons filled, along with cost. So I can get real MPG and $PerMile.

@ChrisJ74 / @spcran4d

It's a good point about not relying on the computer readout necessarily, however, from experience with the IS, the computer readout versus actual is nearly spot on (~0.5 MPG optimistic). In short, let's get actual numbers and computer readout numbers and see how far off they are.

I've read that the 200t engine can use regular but performance takes a hit.

Has anyone done a comparison in mpg between using regular vs premium gas?

Tried one tank on regular and no perceptible difference. The only accurate way to detect any difference is to test both in the exact same environmental conditions which would be difficult to replicate.

About to roll up 1,000 miles and mileage seems to be improving.

You might get away with it in winter when its cold turbo's love cold air, but in summer I'd be running premium fuels all the time. Heat messes with turbo's big time so the computer will have to play with timing and get the fuel trims right.

I'm sure in the summer months running the better fuel mileage will pick up also tire pressure is critical this time of yr. You can gain or lose 2-3 mpg EASY.

First week was 23mpg, then second, third and fourth week was at 25.+ mpg...
I would say I drive 70% hw and 30% city..

Saying "turbos love cold air" is not a justification for an octane change. those factors actually have nothing to do with each other.

Heat does not mess with a turbo as long as your oil cooler is working. Heat messes with superchargers for heat soak.

I don't agree with any of this.

And for the record, all motors love cool air (not cold), regardless of FI or NA. Why do you think everyone runs to a drag strip in the fall to make "hero" runs in the cool air when the density altitude is its lowest?
