Im not sure if it was my imagination but after i dumped the crappy mineral oil and put in the Motul Chrono 300V, the engine felt very different.
Smoother revving,a gain in response and the turbo spooled quicker. And the way the engine pulled was like i had dropped about 50kg out of the cars weight. Noticing this especially when pulling away from lights at low engine speeds.
I guess the reduced friction in the engine is the reason for this?
