I have a 2017 SL and the on board computer have been registering between 36 and 37 MPG on longer trips (200 - 400 miles) on the highway with the cruise control set between 70-75 MPH. Even travelling in the summer, by myself with little luggage on board, I am finding this hard to believe even though a rough calculation of the size of the fuel tank and the miles travelled confirms the figures. On my next long trip I will do an exact calculation to see where i am at. Is anyone else reaching these levels of MPG.

 

Yup. When I'm on the freeway with minimal traffic going 70-80 I hit about 36 mpg as well

 

Under the right conditions I get 36, confirmed by ACar app on my phone and manual calculations.

 

10-4 Guys. I regularly get 35 mpg on cruise @ 70 mph. That's on regular gas too! High 20s in town

 

wish we had big freeways here with high speed limits lol, always traffic, never seen higher than 16mpg for a full tank

 

VQ does not like in town driving...quite thirsty. Not bad on the highway. My Altima gets no where near 35=36 on the highway and it is much lighter than the max....30ish best

 

36.5 my best. 17'sl silver

 

. My last 10. Mostly city

 

yes, my highest is 36.9 on the highway (for a long stretch~100 miles straight). I'm getting 23.5 combined in mixed (and stationary) NYC driving.

 

I'm getting close to that fuel efficiency, but only on open freeway or open highway, and by avoiding cruise control, which lowers fuel efficiency except on perfectly level terrain.

 

 

Mostly hilly rural driving in central Arkansas, A couple of trips to south Louisiana and that helps the overall mileage. The overall 27.5 mpg is better than my '09 SV.

 

I'm getting 17-19 city, 33 max highway (car) = 31 real life.

 

 

This week: 540 miles, highway all the way; light traffic, 74 MPH average, 17.3 gallons 92 octane= 31.21 MPG

 

My best tank is close to 36 mpg, best range 510 miles, averaging about 29 mpg over about 37,000 miles. I do mostly highway driving between 70 and 80 mph.

 

on the few occasions I have driven all real city I average below 20.

On the highway my last trip I barely managed 32 with a strong head wind. Return trip with the wind at our tail I was back to 36.

At 70mph, 36mpg is easy. At 75 I reduce to about 34. 80 gets me 31 to 32, and 85 gets me just under 30.

If I ever were to drive 130 it would not be for long enough to get a reading.

 

Highway mpg is awesome as well as power to overtake other vehicles. Amazing really. However city is crap. Regardless, great vehicle for the $$$. Resale stinks, but that's a market trend.
