I have a 2011 LR4 HSE V8 imported from US to Ghana.
Fuel consumption is about 26-28 l/100 km based on driving in the city and using A/C. When driving on highway the consumption does not improve a lot.
I have changed various sensors, fuel pump, carbon canister, new spark plugs (original LR), new air filter, Odo meter has been calibrated and still have a high fuel consumption. It has a one point been only 16-18 l / 100 km, so I know that it can do better.
Tyre pressure is ok, bearings are ok, driving on octane 95.

So any suggestions to what can be wrong?

Best regards

 

Haven’t they always gotten lousy gas mileage?

 

 

People swear by BG 44k fuel system cleaner. I just ordered a bottle myself for my LR4. Maybe look into it?

 

 

OK, I will try that, have just ordered a bottle.

 

I live in Ghana, so I can't really trust the fuel. Some times they only have 92 octane for weeks. But still should not make such a big difference from 18 up to 26 liter /100 km. Thats a 50% increase in fuel consumption..

 

Fuel thieves?

 

Unfortunately no, I have sealed the fuel cap and been driving it my self on vacation and still same problem. I.e. out driver is not stealing the fuel.

 

I remember hearing that the fuel injectors need to be professionally cleaned every 40K miles
that could have something to do with it!

Good Luck
