bro, in my previous post i gave so many options priority wise and havoline 10w30 is 1 of them, not the only one.
However as you said its still workable in winters.:).
the main thing is that at this stage the poster should not use synthetic oils, as the seals may leak due to strong detergent action, the seals dont leak for a 10w30 mineral oil as its adequately thick enough.
Also most oil discussions recommend using mineral oils in cars after 75000 miles:o and not KM.
However that is a separate discussion:)
In every case the recommended OEM grade gives the best guidelines abt grades.
