Just got back from a trip and lost around 2L of engine oil over 300km, guess she's sprung a leak.
Looking under the car it's all over the place, dripping off the front diff, gearbox, behind the engine even on the back wheel cover and mud flaps.
Anyway, kinda can't tell exactly where it's coming from but best bet seems to be sump or rear main seal.
Any chance either of them gives out with vibration as I did go down quite a few corrugated tracks ?
Probably just try the sump first if no one can shed any light.
