So this Saturday past, my friend and I jacked the car up... unplugged the sump and and let her bleed the black stuff.
And cor blimey! I'm lucky the engine hasn't blown up on me. That oil was blacker than any I'd seen before. The oil filter was full of what I could best descrive as oil jam. (I doubt it'd tate nice though)
It became clear to me very quickly just how negligent I had been.


I'm told I keep good care of my 6 by many. I wouldn't say so, letting it run for 70K miles on the same filter and oil! My head hangs with shame. There is no excuse... I simply... forgot.
So, with 4.25 litres of fresh 10w40 Castrol GTX, she's running smooth, refined and quiet.
In 3K miles I will change the oil again, this time for GTX Magnatec.
Time will tell if the clutch slip was due to oil contamination or not. My friend and I think we sourced the leak to the old filter, so maybe that'll solved itself now too, with the new filter.
Need to give the engine a good blasting to clean off all the oil that was leaked over the last 8 months.
Then I'll be able to see if I've cured the leak or not.
Time will tell.
