    5 w 30 is used to combat high temperature/ loads. When it's 37c outside, you don't want a lower viscosity oil.

    That is technically inaccurate. The engine has a thermostat for a reason and it is to maintain the engine temperature at a fairly constant range. Whether it is 30 deg or 37 deg it is unlikely the engine/oil temperature will change. Under heavy loading conditions such as fast and heavy acceleration, yes as the time between the cooling system catching up to the change in temperature takes time. But not with slow changes in ambient temperature as it can keep up. My engine temperature gauge shows exactly the same temperature regardless of the outside temperature.

    Petrol Engine Oil

    The recommended petrol engine oil, with the exception of Hybrid models, (for Western European driving and weather conditions) is a synthetic engine oil meeting the minimum specification of ACEA A1/B1. The range of Honda Genuine Oil viscosities are 0W-20, 5W40 and 10W40

  2. I have a 2009 Civic 2.0 and this is the sticker from my last oil change at Honda dealer. 0W20 fully synthetic.

    Some information on the advantages:

    The lower viscosity oil is used to gain maximum fuel economy.

    FYI, The Honda genuine engine oil range is all synthetic.
