2015 LR4 SCV6 Gas Mileage

[ugmw177]

You know, the big question i have is why did JLR bother to go to the v6 when it really isnt much if any better on fuel than the N/A v8. The V8 has excellent torque and power without the supercharger. The crazy JLR blanked cylinders to create the v6 is nutty; I guess they could market it as a v6 [better economy] than the v8. My son gets about 19-20mpg on his v8 on the highway and about 12-13 around town.

EPA City rating went from 13 mpg to 15 mpg. Since "per gallon" is our weird reciprocal of actual fuel use, that's something like 20% better.

Edit: Actually did the math -- its ~ 15%

13 mpg = .181 L/km
15 mpg = .157 L/km

Mine is off by quite a bit, I use fuelly to track actual, and for the most part it seems consistent. I'm lucky to get 17 on the highway, around town it's more like 11. What's the procedure for correcting it using the IID tool?

Not in front of the car, but I think in the CCF there's something called "correction factor for fuel usage" or "correction factor for fuel consumption"

My daily work commute is 29 miles one way mostly on highways. On board computer states avg mpg as 19.2-21.0 However, manual calculation indicates 18.0-19.0 avg. 2015 LR4 SCV6 on 18's and 255/65/18 ATs.

Also, the fuel tanks are so small for this type of vehicle imho. A few more gallons would have been nice.

The fuel tank on these trucks is a joke. I spend more time at my local Costco gas station than I do with my children.

I think there must be a massive amount of reserve capacity...even with the light on, I don't know that I've ever put more than 17 gal in, and its supposedly a 22 gal tank.

 

[MellonRover]

I think reserve is 3 gal. I remember seeing it in the owners manual

My highest fillup was 21.614 gallons. You have to drive a lot past 0 miles to empty on the vehicles calculation.

Maybe “a lot past”... but I’m not going to chance it.

 

[f1racer328]

I wouldn't.

I had 5 gallons of fuel in a jerry can. Only reason I did that.
