Lol, I drive 78 miles to work with probably 65+ being freeway/55mph roads. I get at best 28mpg, but usually around 25 to 26 lately in the cold.

If I set out to maximize efficiency I can get like 34mpg max. I think the mud flaps, non functional diffuser, and big wing contribute to a much lower mpg than I had initially thought. But it's all about smiles per gallon baby!

I average between 31 and 37 mpg, filling up around every 300 miles in my SI. Pretty mixed driving

With 60/40 highway/city I've averaged 39.6 MPG, as tracked since 2016, and 41.2 MPG over my last 10 fill-ups.

With 100% city winter driving, I average ~34 MPG.

I average around 28mpg but most of my driving is city. Best I’ve gotten was like 44mpg. I am FBO, W1, e35 tuned 362whp 310wtq so I think those numbers are respectable haha

Now during the winter months, I routinely get around 36-38mpg on min 10 minute highway jaunts, which ends up being around 29 mixed. During the summer I can get as high as 42mpg highway and 36mpg average per tank. Running 93 fuel and Pennzoil Platinum 0w20. It feels like I got better efficiency running Amsoil but it seems negligible from what I've seen in my spreadsheet. I do more highway driving than city.

I average around 26-27mpg, majority of my driving during the week is in NYC.

Best mpg I've gotten is somewhere around 33-34mpg.

I bought it new in April 2020 and I just hit 30k miles. I drive about 172 miles round trip each work day, 90% highway doing 70-75 mph. Current lifetime average is 36.8 MPG. Best tank was 44.1 and worst was 31. I think if the speed limit was a little lower and I was driving closer to 60-65 it would be much better. Pretty happy overall though.

Oh yeah, I just scheduled my 3rd oil change service for this Saturday. Maintenance minder just hit 20% with 10,291 miles since last oil change.

Just my point of view of course : I do an oil change on my cars every 5000 miles or 6 months max ! Why because piston rings are very weak nowadays on modern cars + an oil change is cheap 👍

With a little more details:

Motor: 1.5L CVT
Total mileage: 17k
Avg: 37.6 mpg over the last two years
Hwy/City: 50/50
Octane/fuel: 95 with 10% ethanol
Mods: stock
Oil change: every 8000 miles


Been averaging between 40 and 42mpg(5.6-5.9L/100km) since new. Got about 58000 km now, driving is 80% highway doing 118km/h, on ktuner dual tune running either 15psi or 21 when I feel like having fun, mostly on the eco tune though.
Am I understanding this right, you're running on the 21PSI tune and when you press the ECON Button you're on 15PSI, right?

Do you see a big difference in fuel consumption between these two tunes?

Only when I get into a lot, otherwise fueling is the same at 15 psi on both tunes. Right now with my winters I spin in 3rd gear on the stock tune so the 21 psi tune is kind of worthless haha. The dual tune is nice because I can get more aggressive on the spool of the 21 psi and stay a bit more conservative on eco. It would save more fuel if 90% of my driving wasn't just steady highway speeds.
