0W-20 or 5W-30 for CX-3 in Florida
Hey everyone!
Just wanted to pick everyone's brain on what type of oil weight they are using. I live in Clearwater FL, and just bought a 2019 CX-3 with 48K miles, changed the oil with 0W-20 per the manufacturer's spec but someone told me to switch to 5-W 30 in this climate for better wear protection. Has anyone done this? I understand the spec in Europe is 5-W30 for this exact engine and that the zero weight oils are for EPA compliance here.

Hi John, I live in Miami, Florida and have been using 5W-30 Supertech Syntethic for 4 years now, I bought the car used with 11K miles it now has 58K, before that I also used the same oil on my previous car. In my opinion 0W-20 is too thin for Florida.

For where you live not an opinion on my part but FACT your choice of viscosity is better suited for your operating environment!
