Gas mileage on 2015 IS 250
 

I have the AWD and I am averaging around high 19-20 mpg. Is that about right? I thought I would get at least 23-24 mpg.

We cannot help you without some vital information; what is your highway/city driving ratio? How do you drive? What mode are you in mostly? These are important pieces of info to know before we can accurately give you an idea of where your MPG should be

40% highway, 60% city
90% - eco
10% - sport mode

sounds right

Whats your mile range when filling up?

I have found that eco mode actually makes me mash the pedal even more to get the desired result but not sure if this is the case with the 250 since it has a turbo and would provide more low-end torque. Check your tire psi and alignment, try a bottle of techron or redline if you've never done so but at the end of the day, the 60% city driving is probably your suspect.

For clarification, the 200t has the turbo...the 250 is the smaller version of the 3.5L engine

Thanks for clarification probably would make even more sense that eco mode will be worse for your 250. Try normal mode for a tank and compare the results.

2016 200t f-sport.

60city/40hwy... 90% on Normal Mode, 10% Sport...

19.5mpg......

Never even thought about it, I am constantly hitting the throttle in eco mode.. I will try to put it in normal and see how that goes.

I believe it's 320-330 miles
