A friend of mine with the car has already changed her oil and she said there was no change to the mileage.

 

Ok, I did the following measurements 3 times now.

1. RVR GT - full tank 60 liters (usually refilling at 50%)
2. City driving in 2WD mode

50% of tank = 30 liters = 270 - 285 kilometers = 285 km / 30 liters = 9.5 liters per 100 km -> straight city driving. Average speed range 55 - 70 km/h, Top RPM during acceleration - 2500 - 3000, RPM during cruising when desired speed reached - 1200 - 1500 RPM.

Its real fun when I can get average 8.5 - 8.8 liters per 100 km on some city trips. Could not believe my eyes that is possible but it is. The trick is to ease up on gas pedal when you reach desired speed, accelerate smart, always be ready to ease up on gas pedal watching fuel consumption gauge, trying to get it as low as possible. Of course this is not going to work for people who likes to accelerate fast (however in 90% of cases we are still arriving at the next lights together LOL)

 

That would be my definition of highway driving here. City driving is around 30-35 km/h average according to the car.
However, I get that mileage in my V6 Outlander doing that average speed (55-70), so it seems quite a bit excessive for an RVR.

 

I assume you have no check engine light?

 

nope. no check engine light

 

Good for you, man

Just an observation: RVR, straight highway 100 - 110 km/h = 6.5-7.0 liters per 100 km.

Всего хорошего.

 

Very strange indeed. Is this a consistent thing, or a one time fluke?

I assume you've checked all the obvious things like tire pressure, etc.

Do you think that your driving style could have something to do with it?

 

I recently got one of these. I've had it for over two weeks now, now have a total of around 600 miles on it. For my first fill-up I got around 21mpg combined (50/50 city/hwy). This was not what the computer said, but the mpg I calculated by number of miles driven divided by the number of gallons to fill it up. I live in the Seattle area and we have a LOT of hills around here, which I guess is really bad on the mileage.

I've noticed that the computer shows the best mileage on the (very few) flat sections I have driven on, when I go around 40 mph (arterial roads). If I use cruise control, it shows even more "green" in the bar. I think you really can get the estimated mpg if you live in a flat place.

Another interesting thing I've noticed is that I didn't get much improvement while driving on the freeway. My city mpg on the computer showed around 22 average, but when I hit the freeways, it was around the same and even dropped. I guess trying to climb a big hill at 75mph doesn't really help this. Hills and valleys really kills the mileage. Even though you'd think it would even out.

The most "average" I've seen the computer show was 24.4 in the city (when I ran a few errands last weekend) and 22.8 on the freeways.

I want to try different grades after a few tanks of the regular stuff and will see if that makes any difference. I'll probably fill it up sometime next week, and this time it's going to be about 80% city/20% freeway. I'll post the results here.

 

Filled up yesterday, got 22 mpg with 80% city/20% freeway.

 

another update on our 2011 RVR GT from Toronto, Canada. Average mpg is 9-10 liters per 100 km (improved by 1 liter comparing with last update). 80% city + 20% highway, 2WD mode (no need to turn on 4WD or Lock since driving conditions are good).

Basically 300km per 30 liters (half tank) gives 600km per 60 liters (full tank)
