Your CVT will last much longer if you change the oil. Take it to the stealership if low skills won't change it. Put synthetic fluid in it. Don't shock load it, and don't do burn outs. The one in my Lancer had 350 000km on it, no issues.
Reviews of Mitsuboshi CVT fluid

The fluid only lasts 30K miles. Not 33K, not 50K, only 30K maximum. After that it loses a huge amount of it's lubrication and cooling qualities quite fast. Change fluid and filters every 30K. Use only OEM. These transmissions take Mitsubishi J4 CVT Fluid.
