Question about 2008 Toyota Land Cruiser
I am from the U.S. so you have given me a math problem, if my math is right 210Liters is around 67 gallons of fuel 1300K is around 220 miles so that is about 5 miles to the gallon that is not good.
you do need to have the on-board computer system checked for drivablity codes if you dealer cant do this then find one that can.
i think the premature dark oil and lack of fuel mileage is most likely the same problem, the injection system is over fueling the engine ( now dark oil is normal in a diesel ) but i think this is a little premature, unfortunately there is not much you can do for this problem the toyota fuel system is all electronic and has no adjustments ( not like the old days when we could jack with the pumps ) the on-board computer system can be re-programed ( or flashed as they call it ) and i think this is what you ned to have done, and it can only be done by toyota...sorry
this truck was only rated at 14 miles to the gallon when it was new, so it was never meant to be real efficient anyway, but 5 MPG is way off the mark.....good luck
let me know if there is any thing else i can do for you.

Diesel engine oil does go black after 300 - 500 km depending on how the engine is loaded. What I mean by this is how it is driven, however if this seems to happen all the time weather under heavy or light loads then it maybe a case of having to check the following: Check: 1. Air filter is clean and there is no obstructions in the intake side of the engine. 2. You may need to change the fuel supplier you are currently using, as not all fuels are the same and Mobil are currently running a small additive of bio diesel mixture in there pumps at the moment. 3. Have a authorized Toyota dealer check that the injection timing is ok, it only needs to be out by .5 of a degree to make the engine run uneconomically. 4. Have the accelerator cable checked for free play and adjusted if needed.
You can also put an additive into the tank which will clean the injectors, if the injectors have any wax build up on them this will cause the injectors to leak, so instead of a fine mist coming from them you are getting large droplets which will not burn efficiently.
So have these checked out and let me know if you need more information.
