Over the past few days I've been making my BMW 328i Castrol Free.
And what a good idea it was!!!
I changed the tranny fluid from OEM to the Red Line D4-ATF. First impressions are that the tranny is much more responsive when I'm driving hard, and a hella smoother when i'm simply pimping (as an oilesseur of course).
The RL 75W90 in the diff is giving me the impression of allowing the rear the 'bite' harder when i'm launching or gunning it (butt dyno could be wrong though).
As for the Mobil1 0W40. Costly. But sooo worth it. Can't hear the engine anymore (just the new GruppeM intake I installed - which is sweet too).
Sorry I'm not more scientific in my explanations, but even scientists are allowed to have fun, right?
So thank you guys for all of the info that you've been sharing. It's helped me get more 'umph' out of my car
