hi jaesern, i'm the one recommending my mom on MOS2 10w-40. She had to send me to LRT Kelana Jaya as I have to go to work (taking 1/2 day lulz) and had something urgent to do on 3pm so that's why the COD time had to be 1/2 hour earlier. sorry.

Anyway for the EO review, your Liqui-Moly MOS2 10W-40 does give her Proton Waja a new life. At first after changing engine got no power at all, then it gradually has power. I do notice some black smoke coming out of the exhaust during the initial run and theres some smell, is it due to the MOS2 cleaning the engine?

anyway after travelling around 100km (and after the smoke and smell vanishes), i can say the acceleration is much lighter than before, the engine is smoother and less noise too! What i can tell is that she doesn't regret it at all. Thanks jaesern!

eh jaesern, for mos2 10w-40, how many km for oil change? 7k?
