manual suggests M1 5W30 but i'd recommend M1 0W40 or even 0W30 over 5W30....0W40 meets ACEA A3 specs while the other two do not. 0W30 and 5W30 meet ACEA A5 specs only. since you’re in FLA and heat is a concern, i'd use 0w40 if you can find it. bottom line, however, 5W30 wont blow up your engine... so you should be fine with it :thumbsup:
