Changed the oil today.. Instant result felt was smoother & quieter engine (than eneos 10w40 molybdenum when changed new).. but with extra rm28.. Will monitor its life can last how many km until performance drop.. Nice and friendly seller

Purchased ceratec last nite, went back and poured in that 'teh tarik' thing straightaway.. Idled the engine for about 5 minutes and then shut off..

This morning I can feel that the engine sound much smoother and less vibration too..
Dont know if got improvement on performance or fc (will monitor afterward), but definitely the smoothness is there.. and engine feels a bit tighter too..

Hopefully this effect can last long enough (50k km as per claimed by manufacturer)
Thanks for the great product, and free stickers too
