Valvetrain pic, UK Essex V6, 20W-50 Dino.

[FCD]

Picture from today, 20W-50 Dino since August 2015, total of 5L of make up oil added, so an entirely new sump full of oil over last year.
90-100k miles on engine, engine is at least 36 years old, i don't know the exact mileage or year the engine was made because it's not the original one.

Pretty good i think for a low tech 20W-50 Dino juice.

Look very good. Deposits are maybe about the add pak, not so much about the base oils ...

The Valve cover gaskets are leaking so i'll get some more pics when i replace them.

Base oil is very important in preventing deposits.

Yah with a little bit of sludge in the corners was the valve train when I opened up the VC to set the valve at 300K for the first time on the Borman 6. That was my first 528e.

Engines don't really have to be pristine to run alright, i'll continue using 20W-50 Dino but Valvoline VR1 rather than cheap Shell stuff, the engine seems to like it.

There's working surfaces and nooks and crannies...although I like clean nooks and crannies, working surfaces are where it's at.

The engine is at least 36 years old and i'm scared to put in something that would loosen up all the potential gunk inside the engine.
