Castrol Activ Scooter 4T 10W-30 Engine Oil (800ml) with 80W-90 Gear Oil (120ml) Combo - SKU: CAS4TEO

Complete Drivetrain Protection: Features 800ml of 10W-30 engine oil along with a 120ml squeeze tube of 80W-90 transmission gear oil for a complete service.

Improved Actibond Technology™: Protective molecules cling firmly to internal engine surfaces, providing continuous protection during start-up, warm-up, and extreme heat cycles.

Synthetic Technology Formulation: Resists thermal breakdown under high temperatures, making it ideal for next-generation BS VI scooter engines that run hotter.

JASO MB / API SN 4-AT Standard: Specially engineered for automatic 4-stroke gearless scooters with dry clutches to minimize engine drag and maximize fuel economy.

Heavy-Duty 80W-90 Gear Oil: High-pressure gear fluid cushions reduction gear teeth, preventing gear pitting, whine, and premature mechanical wear.

Give your automatic gearless scooter continuous protection and whisper-quiet operation with the Castrol Activ Scooter 4T 10W-30 Engine Oil (800ml) with 80W-90 Gear Oil (120ml) Combo Pack (SKU: CAS4TEO). Modern city commuting subjecting automatic scooters to heavy stop-and-go traffic causes engines to run significantly hotter. Formulated with improved Actibond Technology™ and synthetic technology, Castrol Activ Scooter 10W-30 clings to critical engine components to deliver 3X continuous protection against heat breakdown, friction, and wear. Paired with the dedicated 80W-90 gear lubricant, this complete service combo safeguards both your engine and final drive reduction gearbox.

Skipping final drive gear oil changes or using standard mineral oils leads to thermal breakdown, rough engine movement, and noisy transmission gear wear. Upgrading to the CAS4TEO Castrol Activ Scooter engine and gear oil combo kit ensures smooth throttle response, reduced gear friction, and long-term mechanical reliability for your daily ride.

Recognizing Lubricant Degradation Symptoms

Rear Wheel / Gearbox Whining: A high-pitched metallic humming or whining noise from the rear wheel during acceleration, caused by broken-down 80W-90 gear oil.

Engine Overheating & Rough Movement: Increased heat radiating onto floorboards and sluggish acceleration resulting from degraded mineral oil breaking down under heat.

Sluggish Throttle Response & Low Mileage: Reduced fuel efficiency and loss of pick-up caused by high internal friction in old, contaminated engine oil.

Dark / Metallic Drained Oil: Discolored black engine oil or metal-flecked gear oil observed during drain procedures.

Maintenance & Service Best Practices

Synchronized Oil Replacements: Always replace the 120ml final drive gear fluid alongside or every second engine oil service to ensure long gearbox life.

Easy Application Nozzle: Utilize the built-in pointed nozzle of the 120ml 80W-90 tube to easily inject fluid into the gear housing without mess or overflow.

Warm Drain Procedure: Warm up the scooter engine for 2–3 minutes before draining to ensure complete evacuation of old oil and suspended metallic particles before refilling.
