Synthetics actually burn off off less, That is true synthetics. about 80% of synthetic oils are group III oils so not true synthetic like Mobil1 or Motul. If your not running your oil more than 10000kms then your wasting money on synthetic on a gas engine. Just be sure to use a oil with a good API rating.

I would inspect your PVC system on your vehicle if the valve is stuck or the internal spring is collapsed , the engine will burn oil. Also check for engine oil in the air cleaner housing or intake tube. I doubt you have worn rings on a Vios unless it's physically smoking when your driving.
