Fuel Economy - What're you getting?

gtman · Jun 5, 2019

Testing my latest Ktuner tune out, I got 24 mpg in mixed highway / city driving earlier today.

Of course, I was pushing it pretty hard.

Just a little bit ago I took another drive and drove it "normally" and got 39 mpg.
You just can't beat the Civic's combo of power and economy.

Just about to hit 30,000 KM and 18 months and overall here is my breakdown

Highway regardless of weight or season @ 125 KPH / 77 MPH - 5.5l/100 or 42-43 MPG (Only less when in seriously hilly areas)
Highway at 90 KPH/55 MPH - 5.0l/100 or 47 MPG

City commute in the summer - 8.2 or 28.7 MPG
City commute in the winter - 9.5 or 24.8 MPG (Note I use remote start a lot because Canada)

I never use Eco mode and only use straight gasoline as most stations in Canada sell super with no ethanol for use in machines that really hate ethanol (lawn mowers and such). I don't use it for "more power" from octane. I use it to have more actual gasoline in my gas

90 mile trip (each way) this weekend in the Si to take my son to a lacrosse tournament. Scenic byway (Rt29) in Virginia, essentially from Dulles Airport to UVA in Charlottesville VA

Per the computer:
1) 49 mpg on the cruise to UVA (it was mostly down hill

)
2) 46 mpg on the cruise back north

Windows down a few inches. Sunroof tilted up. No AC needed. Even if the computer reads high like some say (even if its 5% high, that's still 44-47mpg). With a light foot, I am always surprised just how good the mileage is in this car. The last 10 tanks of gas have been in the 38-40mpg range overall.

I average 360-450 miles per tank.

13.000km (8100miles) so far average consumption is 6.6 l/100km or 36 mpg and i do WOT daily also doing some fast mountain runs weekly

On a recent drive to Bangor, I was able to find out where the sweet spot for speed and fuel consumption is for a non-modded 2.0NA CVT.

120 KPH/75 MPH is good for close to 43 mpg but if you take it to 130/80 then it drops to about 37 MPG. This was with 3 adults counting me.

Yay for Maine speed limits on the I95!

Really good numbers for 75 mph especially considering the 3 adults in the car.

I was getting that consistently last year at the 120/75 but never went anywhere that I could set the cruise at 130 for a long stretch and not have the RCMP get angry with me (Max limit in NB is only 110 so 20 over would have been pushing it too much.). This drive to Bangor the other day let me find out for sure how much worse it got at the higher speeds. I also did a run several weeks ago with it set at 110 and there was only a 1 MPG improvement so my guess is that somewhere between 120 and 130 is where the drag finally becomes a real issue.

I should note I also always run gas that is known to always be just gas. No ethanol. Typically, this means it is 91 octane gas as a lot of regular is indeed 10% ethanol.

Took a trip yesterday & the Interstate had big delays going out & the car got 39.6mpg. But coming back home people were really boogying. Was 90 miles one way with about 85 of that on the Interstate. There were long stretches when I was “forced” to keep up with traffic at 80-85mph, most of the time doing at least 75mph. The speed limit signs were meaningless. Got home & the trip readout indicated 45.3mpg for that return trip. Makes me wonder what it would have been if I kept the speed at 70mph.

I have a question about fuel and usage. So I live in Slovenia and we can only get 95 or 100 octaine, the difference is about 0.18€ (0.20$). My question is once I get my Civic Hatch in November should I stick to the 100 octaine premium or is 95 octaine completely OK and the 100 octaine will not add to the MPG? I don't know how much the premium fuel affect usage on turbo engines as you could fuel my current car with Nitro and it wouldn't go much faster

I would go with your owners manual recommendation. The Honda turbos are made in both premium and regular gas configuration with the premium outputting more power. The octane ratings standards can be different between regions/jurisdictions so looking at North American gas and its 87/89/91/93 selection as being lower overall than what is in most of Europe is not accurate.

Also, and don't quote this as fact, but when I was looking through product literature on the 1.5T on one of the models of Civic, it stated that the use of less than 91 was fine but would result in a loss of power from the factory rating. This tells me that the electronics and sensors in cars have reached the level where they can be set up to handle whatever you toss in them and if that means more power to the wheels if possible, then it will deliver.

Thanks for the answer! I'll do some research to see if the "premium" fuels we have in Slovenia are really any better than the normal 95 octanes. Also yeah when I was test driving a Civic Hatch it did have a sticker on the inside of the fuel lid that said that 93 should be used for optimal performance.

From what I've skimmed on the net the OMW 100 Octane premium is quite good and people have done some tests with it and it did increase the economy by a miniscule amount. And if you read the brochure of the Premium fuel (yes they have a banging brochure for the premium fuel) it says that it makes the engine run better, smoother and in the long run use up less oil, and so forth.
