Hey Elton,

The Semi oil is damn GOOD! 10w-30. Pour into my Myvi + Revo and it's indeed so much silent compared to Shell 10w-40. Myvi can still go on after 110km/h where previously i don't do it due to the noise from the engine. Will come back to you in a week or 2 for the semi oil, threebond and ceretec maybe. Need to arrange my time first.
