Bro, now you came to know that how many people love your comments.
I read oftenly all the comments posted by pakwheelers and all comments are precious to everyone who search for new things.
So as a habbit, I save the good/appealing comments for future reference and so in your case. However, as we all are here to increase knowledge from each other so I add one thing more that AHL manual also tells that we can use 15W-40 oil for above 40c temperature as shown in attached pic. Now what you say?
