I changed engine oil a yr ago with Mobil Extended performance.
This car is typically driven on freeway - with pandemic, its at home resting! It should be back on duty in Sept 2021. If there is no reason to change good looking oil, I rather not!
I do not know Mazda's recommendations - believe they recommended Synthetic 0w-20. Now we have Extended Performance.
Update:
Owners manual asks to use Castrol. No mention of Synthetic.
With Full Syn, I hope it can do more than a yr. People have been changing once a yr, assuming they drive less than 5k/yr.
- I drive once a month just to maintain it, so I drove 300-600 miles only in the last 12 months
- I did not check engine oil color but will do so - I bet it looks brand new oil.
