I recently bought a Honda Civic Sport Hybrid Hatchback, but I’m experiencing poor gas mileage. I’m not sure if there’s a break-in period or procedure I need to follow, but the car isn’t giving me the fuel efficiency I expected. For comparison, my 2016 Honda Civic averages around 33-34 MPG, and the hybrid isn’t performing noticeably better.

I’m unsure if I’m doing something wrong or if there’s an issue with the car itself, but it’s frustrating. I’m considering taking it back to the dealer to figure out what’s going on.

Has anyone else experienced something similar or know why this might be happening? Any advice would be appreciated before I take it in for service. Thank you! View attachment 23581

These data look great - thank You !

Focusing in the English system measurements, I was surprised that at 75 mph the electric drive was still occasionally on.

And the mpg numbers are encouraging. My gas powered FIT only gets around 36 mpg at 75 mph. And of course the hybrid does nothing but get much better at lower speeds.

At 10,000 miles (16,093 KM) for my almost a year old Hybrid HB Sport Touring, here are my observations on mileage. If just doing regular driving at 62 Miles per hr or 100 Km/hr on highway and what ever city speed (30 plus miles per hr) with 50/50 split on hwy and city driving, during cool weather last few weeks (not much use of the air con) and my last two tank logged 58.3 MPG or 4.03L/100 km measured at the pump. During the hotter weather with pretty much air con on all the time, it still got about 53 MPG or 4.44 L/100 Km. Worse are winter times. During the month of Feb, it actually measured out at 40.5 MPG or 5.8 L/100 Km.

I think driving habits and outside temperature for sure affecting the mileage a lot. During a run on highway driving which I averaged at 78 mile/hr (125 km/hr), the car's info said I was at 44 MPG (5.35 L/100 Km). Hybrids is the same as ICE, faster speed uses more fuel.

I have same vehicle in urban grey pearl. I am feeling that the hybrid system is not engaging as much as it should be. 🤔 now the weather is turn cooler - I’m in Halifax NS. so it will be interesting. You have snow tires - did you mount them on the OEM alloys wheels or did you purchase new rims. Because the rotors are bigger on the hybrid model and require a rim with a deeper offset. ( ie +50 ) cant find in steel rim to so had to buy an alloy 18 in with the +50 offset.
because the vehicle has no spare and I was going on a fairly long trip - I purchased the aftermarket 18 inch +50 offset and a tire to have a spare - bit of a pain for sure. i am hoping to park the civic for a few months this winter - it is too low and it’s not AWD . We have a 2018 Subaru better equipped for winter driving so hopefully we can manage with one vehicle - but I am very interested how you are managing the snow tires on the Civic. And your mileage concerns.
