A fellow member texted me today and was worried.
He said that when he went for engine oil change today, for his Altis 1.6, to a Caltex / Havoline engine oil change booth, they under-filled and only poured in 4L (which I think is much short of the amount mentioned in the manual, with oil filter change).
They gave the analogy that its their standard practice that they only pour in 4L in 1.6 Altis, irrespective of the quantity mentioned in the manual, and that, pouring in engine oil up to the quantity mentioned in the owners manual, damages the engine seals.
If in manual, it has been clearly written that with oil filter change you need to pour in 4.2L, then how can pouring 4.2L after oil + oil filter change, can damage engine seals?
If someone has logical explanation to it, the kindly elaborate, else if, I am clueless what to say and comment on it?
