Perodua Ativa Carbon — Port Injection
Ativa 1KR-VET: port injection — no intake valve carbon buildup. No walnut blast ever needed. Regular 5,000 km 0W-20 changes keep combustion clean despite the turbo.

Ativa Carbon Buildup
- 1KR-VET is port-injected — less intake valve carbon than direct-injection turbo engines
- Turbo oil: ensure no oil seeping from turbo seals — burning oil creates carbon deposits
- Regular highway driving at varied RPM helps keep intake clean
