According to the Honda ADV350 Official Owner’s Manual (Honda Moto Pub) Specifications, the 2022–Present Honda ADV 350 (chassis NF13/ADV350A) requires 1.3 L (1.37 US qt) of SAE 10W-30 (JASO MB, API SJ or higher) engine oil for a drain-only change and 1.5 L (1.59 US qt) with filter service (15410-MCJ-000 / HF204). Standard solo cold tire pressure is 200 kPa / 2.00 bar / 29 PSI front (120/70-15 M/C 56P) and 225 kPa / 2.25 bar / 33 PSI rear (140/70-14 M/C 62P), paired with 1× NGK LMAR8L-9 spark plug(s) and a YTZ10S / FTZ10S battery.
Drain only: 1.3 L (1.37 US qt)
R 225 kPa (2.25 bar)
Est. Range: ~344 km (214 mi)

4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Introduced in 2022 on the NF13 chassis, the ADV 350 gained preload-adjustable remote-reservoir rear shocks and a 5-inch TFT display for 2025 while retaining identical eSP+ 330cc fluid and plug specs.
Oil & Clutch Mechanical Engineering Note
Do not confuse the ADV 350’s powertrain with the X-ADV 750! While the X-ADV 750 uses a wet-clutch DCT requiring JASO MA oil, the ADV 350 runs Forza’s dry centrifugal CVT and explicitly specifies SAE 10W-30 JASO MB in the Honda Owner’s Manual.
Garage Wrenching Gotchas
- After gravel or dusty touring routes, clean the left-side CVT cooling air-duct foam filter in addition to the main engine airbox element to prevent belt overheating.
- Stock block-pattern tires cup rapidly on tarmac if front pressure drops below 200 kPa (29 PSI); verify cold tire pressure before highway touring.
5. Frequently Asked Questions (FAQ)
Does the Honda ADV 350 require JASO MB or JASO MA engine oil?
The official Honda ADV350 Owner’s Manual explicitly specifies JASO T 903 standard MB (SAE 10W-30, API SJ or higher) because it uses a dry centrifugal CVT clutch rather than a wet clutch.
How much oil does the Honda ADV 350 need with a filter change?
Refill capacity is 1.3 L (1.4 US qt) for an oil drain only, and 1.5 L (1.6 US qt) when replacing the spin-on oil filter.
What is the real-world touring range of the Honda ADV 350?
With an 11.7 L fuel tank and ~29 km/L real-world consumption, the ADV 350 reliably covers 320–340 km (200+ miles) per tank.
