Engine oil
Justin recommends 0W-30 or 5W-30 for supercharged applications, subject to climate, manufacturer requirements and engine condition.
VT Supercharger Maintenance Schedule
Forced induction adds maintenance responsibilities that should be planned before chasing more boost.
Routine interval
The supplied VT reference calls for engine oil and filter replacement around every 5,000 km and regular intake-filter inspection.
Supercharger service
The supplied reference lists supercharger oil replacement at 100,000 km. Justin recommends about 75,000 km or less with a smaller pulley and commonly targets about 50,000 miles or less.
Belt, plugs and fuel
Inspect the belt and plugs regularly, use the required fuel grade and follow the plug specification supplied for the calibrated build.
