Lucas is no addicted super thick oil.
Which means all it does is thicken what's in the sump and dilutes the additive package. Neither are good.
If you want thicker oil use thicker oil. Simple. If you've got an oil leak use liqui-moly motor oil saver. Unless the gasket is physically broken motor oil saver will slow the leak til you can get it fixed properly however I've found that once it's used you don't need to fix it.

Better to diagnose and fix the problem, though.
Nice.
