My 2005 Endeavor with 60000 km burns 1 litre of oil every 1000 km at highway speeds, about half that around town. Is this a normal occurrence or is there a problem with the motor?

is is odometer reading?
all cars burn oil if driven real fast, at 80mph, lots.
what i need is ,
1: speeds driven. avg.
2: and what weight, oil , is it hot there, sure, then run 10w-40 oil.
3: how many liters of oil per miles.
some cars go for years, burning 1quart of oil per 3000 mile.s
1L/5000 km to 1L /1000 km. (new car to old)
even more. on older engines.
if the engine runs good, drive it and change oil more often.
check oil at every petrol fill up, and learn what your engine needs
all engine burn oil by design. its a fact.

do an engine compression test.
2 times wide open throttle.
on a warm engine
if lower that spec, 150psi?
then add 1 teaspoon, of oil to spark hole , see if compression rises
if it does, its rings are old.
post the numbers, if all are 150 or more , drive it like you stole it.
half joking there, but drive it. and change oil often and check oil levels
every fill up or every other (depends on reality)

GASKET.
post the compression test readings. only NUMBERS count.
we need numbers and engine size.

90 deg C is normal for a vehicle standing for some time. What does the temp read when the car is on the highway doing around 100 km/h.

That fuel consumption is a bit heavy, but not excessive, depending on the driving conditions. In heavy traffic and slow town driving with a lot of stop starts it would be acceptable but on the open road in 2 wheel mode it would be excessive. Kia do not seem to manage much better than about 8-10 l/100km, even on their sedans.

change the plugs and the air filter &try not to speed, that always consomes more fuel. if that dont help, change the plug wires

All VW product have plasma coated bores and for this reason will "use"oil.the workshop manual says "1 litre every 350 km is ACCEPTABLE".I have NEVER had a car THAT BAD,unless worn out.
check your oil every 500 miles MAX.and use 10/40 semi synthetic.(as per VW Europe/middle/far east manual.)change every 10k inc filter.

Oil consumption is outside specification, and needs around a litre of oil every 7 500km, not unusual for a race-bred engine. But, if you are only getting 1 litre for only 1500, you might want to change brand of oil, or ensure you are using the right type of oil.......

11.1 x 6.25 = 69.375 Litres

If your oil pressure is running in the red this would indicate too much oil in the system. You should have your oil changed and refilled soon or you run the risk of burning out the oil pump. At idle your pressure should be just over a quarter of what your gauge has. At highway speed it should not exceed 3/4 of the gauge unless your going in excess of 100 MPH. Change the oil and filter and your vehicle should be fine.

the most common source is the turbo shaft seals leaking oil.
