I'm already using 5w40 when this engine normally takes 5w30 (D15Z6), and I could go even further because this country is so warm that even 10w40 is within Honda's spec (regularly have 40C days in summer and winters never drop below 0C). But in any case I doubt it's the oil rating because the engine was fine burning only 1L of oil every 10k Km until a month ago when it started burning oil overnight.
In any case now that you mention it I might as well share pic related from my Civic's manual I still have, with the recommended oil ratings for D series engines relative to ambient temperature, someone might find it useful.
