I have a 2008 Civic with the 1.8L engine. I’m currently running Valvoline Restore and Protect 5W-30 in it. The car runs fine. I live in east central Florida.
Since you’re limiting it to Walmart 5W-30 oil and filters, I suggest either Valvoline Restore and Protect or Pennzoil Ultra Platinum and a Mobil 1 oil filter.
