MegaMAX — 3-Tier US Technology Engine Oil for Manual, Semi-Auto and Scooter Motorcycles in Ho Chi Minh City

Every motorcycle owner in Ho Chi Minh City eventually faces the same question: which oil is actually right for my bike? The answer depends heavily on the type of motorcycle — and getting it wrong means paying for protection your engine does not need, or worse, damaging a component the oil was never designed to protect.
The critical distinction is between JASO MA/MA2 and JASO MB. Manual bikes and semi-automatics use a wet clutch system that requires JASO MA2 oil — the friction additives must be calibrated precisely for clutch engagement. Scooters with CVT transmissions need JASO MB, which is formulated entirely for lubrication and cooling without wet clutch considerations. Using the wrong standard causes clutch slip on manual bikes or wasted additive spend on scooters.
MegaMAX — Huynh Chau Distributor's proprietary brand built on U.S.A. technology — addresses this with a 3-tier lineup that covers all three motorcycle types: manual clutch bikes, semi-automatics, and scooters. This article maps each product to the right bike type so you choose correctly.
1. LUXURY Tier — API SN+ for High-Performance Bikes
The Luxury tier is the top of the MegaMAX lineup, designed for bikes with the most demanding lubrication requirements. Both products carry API SN+ — the highest current standard, above SN, SL, and SJ.
1.1. Luxury Rover — Manual Clutch Bikes 150cc+ (JASO MA2)
Luxury Rover is formulated specifically for manual clutch bikes — motorcycles where the rider squeezes the left-hand clutch lever and shifts with the left foot. Target models: Yamaha Exciter 155, Honda Winner X, Yamaha R15, Honda CB150R. Its core technology is Ester Core — a premium ester base delivering superior lubrication under high RPM and high temperature.
- Viscosity: SAE 10W-40 | Standard: API SN+, JASO MA/MA2
- Price: 0.8L — 209,000 VND | 1L — 219,000 VND
- Oil color: Luminous blue tint, square can with smart-pour spout
JASO MA2 — the highest wet clutch standard — ensures precise friction between clutch plates. With Luxury Rover, clutch engagement is crisp with zero slippage even under hard acceleration. Important: never use JASO MB oil in a manual clutch bike, as it will cause clutch slip.
1.2. Luxury Scooter — Premium Scooters (JASO MB)
Luxury Scooter is formulated exclusively for automatic scooters — bikes with a CVT transmission where the rider only twists the throttle, with no gear lever and no clutch lever. Target models: Honda SH 150i, SH 300i, Honda ADV 150, Yamaha Xmax, Honda PCX 160, Vespa. Technology: P.A.O Core — Polyalphaolefin synthetic base specifically engineered for CVT engines.
- Viscosity: SAE 5W-40 | Standard: API SN+, JASO MB
- Price: 0.8L — 219,000 VND
JASO MB is fully optimized for CVT engines with no wet clutch — the formula focuses 100% on lubrication efficiency and thermal management. The 5W-40 viscosity grade enables faster cold-start oil circulation, critical because 80% of engine wear occurs in the first seconds after ignition.
2. RACING Tier — Full Synthetic API SN for Mainstream Bikes
Racing is the mainstream full synthetic tier — Fully Synthetic, API SN — suitable for most motorcycles made after 2010. Two distinct products, one for each drivetrain type. Do not interchange them.
2.1. Racing 4T — Semi-Automatics and Manual Clutch Bikes (JASO MA2)
Racing 4T covers semi-automatic bikes (foot-shift with no hand clutch) and manual clutch bikes: Honda Wave Alpha, Wave RSX, Dream, Future, Yamaha Sirius, Jupiter, Yamaha Exciter 155, Honda Winner X. This is the best-value JASO MA2 Fully Synthetic option in the lineup.
- Viscosity: SAE 10W-40 | Standard: API SN, JASO MA/MA2
- Price: 0.8L — 167,000 VND | 1L — 177,000 VND | 1.2L — 198,000 VND
Full synthetic creates a thinner, more uniform film than mineral oil — reducing internal friction noticeably during the low-speed, high-temperature stop-and-go conditions of Ho Chi Minh City. JASO MA2 ensures the clutch holds firm on manual bikes and protects the shift mechanism on semi-automatics.
2.2. Racing Scooter MB — Mid-Range Scooters (JASO MB)
Racing Scooter MB is formulated exclusively for mid-range automatic scooters: Honda Vision, Air Blade 150, SH Mode, Honda Lead 125, Yamaha NVX 155, Yamaha PCX, Honda ADV, Yamaha Janus, Yamaha Nouvo, Vespa LX. Best-value JASO MB Fully Synthetic in the lineup.
- Viscosity: SAE 10W-40 | Standard: API SN, JASO MB
- Price: 0.8L — 177,000 VND | 1L — 188,000 VND
Without wet clutch friction requirements, JASO MB's additive package focuses entirely on lubrication efficiency and heat management for CVT operation. The result: quieter running, stable engine temperatures during prolonged idling, and reduced wear in city traffic.
3. MAX Tier — Semi-Synthetic and Mineral for Older Bikes
The MAX tier targets older motorcycles or riders who want better protection than pure mineral oil without the cost of full synthetic. Like the Racing tier, it has two separate products by drivetrain type.
3.1. Max Speed Ultra and Max Scooter Ultra — Semi-Synthetic
Max Speed Ultra (semi-automatics + manual clutch bikes, JASO MA/MA2) and Max Scooter Ultra (scooters, JASO MB) both use Premium Synthetic + Power Core technology — semi-synthetic formulas with MegaMAX's proprietary Power Core additive.
- Max Speed Ultra: SAE 10W-40, JASO MA/MA2, API SL — 0.8L: 146,000 VND | 1L: 156,000 VND
- Max Scooter Ultra: SAE 10W-40, JASO MB, API SL — 0.8L: 156,000 VND
Semi-synthetic offers significantly better engine protection than mineral oil at a price below full synthetic. Whether your bike is a semi-automatic, a manual clutch bike, or a scooter — just pick the correct JASO standard (MA2 or MB) for your drivetrain type.
3.2. Max Power — Heavy-Grade 20W-50 for Older Semi-Automatics
Max Power uses a mineral base with the HGM-MAX + Power Core formula, featuring 20W-50 heavy-grade viscosity. Designed for older semi-automatic and manual bikes (older Honda Wave, Dream, Yamaha Jupiter) with worn engines, high oil consumption, or heavily overhauled drivetrains.
- Viscosity: SAE 20W-50 | Standard: API SJ, JASO MA2
- Price: 0.8L — 125,000 VND | 1L — 135,000 VND
The thick 20W-50 grade compensates for worn piston-cylinder clearances, reducing oil consumption and managing heat in high-mileage engines. Not recommended for new bikes or sport manual bikes, as the high viscosity increases internal friction and reduces engine performance.
4. MAX Gear Oil — CVT Gearbox for Scooters Only
MAX Gear Oil is a separate product for the CVT gearbox of automatic scooters — it is not engine oil and cannot substitute for it. Compatible with: Honda PCX 160, Yamaha NVX, Vespa, Suzuki Skydrive. Semi-automatic and manual bikes do not have a CVT gearbox and do not need this product.
- Viscosity: SAE 80W-90 | Standard: API GL-5, MT-1
- Price: 120ml — 62,000 VND | Oil color: Golden tint
The EP (Extreme Pressure) formula handles the intense gear-mesh pressures inside the CVT gearbox — regular engine oil cannot do this. Changing gear oil every 8,000–10,000 km keeps the CVT running quietly and significantly extends gearbox lifespan.
Conclusion
MegaMAX covers all three motorcycle types with a clear 3-tier system: manual clutch bikes and semi-automatics use JASO MA/MA2 products (Rover, Racing 4T, Speed Ultra, Max Power), while scooters use JASO MB products (Luxury Scooter, Scooter MB, Scooter Ultra) — and the two standards must never be mixed. From Luxury for sport bikes to MAX for older engines, all backed by U.S.A. technology with the brand's signature luminous blue oil color.
