Yes. That would be wonderful.
But I think, 4L pack would be economical and cheaper when compared to 1L x 4 (or 3) packs. You can save 1L oil every time, and on 4th engine oil change, nothing will be left.
Wait a minute.
I have just checked, and its being offered in 1L, 4L, and 6L packing. Your issue is resolved.
4L and 6L cost per L is the same, i.e. Rs. 780.
You can buy 02 packs; one 1L, and one 6L.
It also has the advantage that it is fully synthetic (I think, other links which I have mentioned above are semi-synthetic, or mineral based), but not matter much. Caltex and Shell are also very respected and reputed brands.
