Total mileage vs HEV mileage
The Australia handbook uses two different mileage bases. Total vehicle mileage is the vehicle's overall travelled distance. HEV mileage is used for several engine-related intervals and should not be silently treated as the same number as the odometer. The handbook also shows that the instrument cluster can display Total Mileage, HEV Mileage and EV Mileage, so owners should check the vehicle display and confirm the correct value with BYD before calculating engine service.
| Label | Used for | Owner caution |
|---|---|---|
| Total vehicle mileage | Many chassis, brake, tire, coolant-level, HV exterior, charging-connector and software/fault-code checks | Use the total odometer only for rows that the schedule describes as total mileage. |
| HEV mileage | First maintenance, engine oil/oil filter, idle-speed, crankcase ventilation, spark plugs, fuel filter and engine air filter rows | Do not use total odometer as HEV mileage unless BYD confirms the vehicle displays and service system match. |
| Time interval | All rows that say months/years | Use time or mileage, whichever comes first. |
| Condition-based | Severe-use and visible-damage checks | Inspect sooner when the handbook says more frequent checks are needed. |
The generic 15,000 km maintenance estimator is intentionally not used for SHARK 6. A reliable calculator would need market, model year, total mileage, HEV mileage, last service date and severe-use inputs.
First maintenance
| Due point | Mileage basis | Included items | Notes |
|---|---|---|---|
| 6 months or 3,500 km, whichever comes first | HEV mileage | Vehicle basic maintenance, engine oil replacement, oil-filter replacement, engine idle-speed check, crankcase ventilation-system check | This is not a generic 10,000 km inspection. Confirm the service entry by VIN and service history. |
Engine and fuel-system maintenance
| Maintenance item | First due | Recurring interval | Mileage type | Action | Severe-use note | Confidence |
|---|---|---|---|---|---|---|
| Engine oil and oil filter | First maintenance: 6 months / 3,500 km | After first maintenance: every 12 months / 10,000 km | HEV mileage | Replace engine oil and oil filter | Short trips in cold HEV operation and long low-speed creeping are severe-use signals; service sooner if BYD advises. | Confirmed |
| Crankcase ventilation / PCV-related system | First maintenance checked | Every 12 months / 10,000 km after first maintenance | HEV mileage | Service/replace according to the handbook wording and dealer procedure | Do not improvise PCV service; use the correct BYD parts and procedure. | Confirmed |
| Engine idle speed | First maintenance checked | Every 12 months / 10,000 km after first maintenance | HEV mileage | Check | Owner should report rough idle, unusual vibration or warning messages before the next service. | Confirmed |
| Spark plugs | 42 months / 33,500 km | Every 48 months / 40,000 km after the first replacement | HEV mileage | Replace | Use correct plugs and torque through service; not an owner repair item. | Confirmed |
| Fuel filter, non-integrated | 18 months / 13,500 km | Every 24 months / 20,000 km after the first service point | HEV mileage | Check and replace as listed by the handbook | Fuel smell, hard starting or repeated refueling shut-off should be checked by service. | Confirmed |
| Engine air-filter element | 18 months / 13,500 km | Every 24 months / 20,000 km after the first service point | HEV mileage | Replace; inspect and replace earlier where necessary | Dusty conditions can require earlier inspection/replacement. | Confirmed |
| Fuel tank cap, fuel lines and connections | 24 months / 40,000 km after first maintenance | Every 24 months / 40,000 km | Total mileage | Check cap, lines and connections | Do not repair fuel lines yourself. | Confirmed |
| Charcoal-canister dust filter | 2 years / 30,000 km, or repeated fuel-pump auto shut-off | Same rule | Mileage not explicitly separated in the extracted row | Replace dust filter | Repeated fuel-gun shut-off during refueling is a service signal. | Confirmed |
| Engine coolant | 4 years / 100,000 km | Every 4 years / 100,000 km | Total mileage/time | Replace long-life organic-acid coolant | Do not drain coolant yourself; PHEV cooling circuits are service work. | Confirmed |
Hybrid, electric-drive and high-voltage checks
| System | Interval / trigger | Mileage type | Owner-safe meaning |
|---|---|---|---|

Severe operating conditions
The handbook lists severe conditions and tells owners to shorten the routine mileage interval based on actual use. It does not create one universal shorter interval for every item, so this page does not invent one.
- •Cold HEV operation with short continuous trips below 5°C, especially less than 15 minutes.
- •Long low-speed creeping below 10 km/h.
- •Dusty areas or salt-laden air.
- •Bumpy, puddled, muddy, sandy, snowy or mountain roads.
- •Cold-weather operation.
- •Frequent or sudden braking.
- •Frequent towing or heavy loading.
- •Taxi, commercial or high-use operation.
- •Congested urban driving above 32°C for more than half of travel time.
- •Sustained speeds over 120 km/h above 30°C for more than half of travel time.
- •Frequent overloading.
| Source wording | How to use it |
|---|---|
| Officially shorter interval stated for a row | Use the shorter row-specific interval. |
| Inspect more often / increase frequency | Ask BYD service to adjust inspection frequency for the affected system. |
| Replace earlier if necessary | Replace based on condition, not a guessed universal kilometer number. |
| After water exposure or impact | Arrange inspection before further charging or high-speed driving. |

Owner-safe checks between services
- •Check tire pressure and visible tire damage.
- •Watch for warning lights, service reminders and abnormal hybrid-system messages.
- •Check for visible fluid leaks under the vehicle without touching HV components.
- •Check engine-oil level only as described in the owner handbook and only when safe to do so.
- •Look for obvious charge-port debris, burn marks or damage before plugging in.
- •Monitor coolant-warning messages and visible reservoir levels only where the manual permits owner checks.
- •Keep service invoices and note whether HEV mileage and total mileage were recorded.
Do not open high-voltage parts, disconnect orange cables, repair brakes, drain coolant, service HV connectors, change hybrid transmission fluid or clear diagnostic codes as a DIY task.

Frequently asked questions
How often should a BYD SHARK 6 be serviced?
For the confirmed Australia handbook, the first maintenance is due at 6 months or 3,500 km of HEV mileage, whichever comes first. Many later vehicle-level checks use 12 months or 20,000 km of total mileage, while several engine rows use HEV mileage.
What is the first BYD SHARK 6 service?
The first maintenance is listed at 6 months or 3,500 km of HEV mileage and includes vehicle basic maintenance, engine oil replacement, oil-filter replacement, engine idle-speed check and crankcase ventilation-system check.
Does BYD SHARK 6 need engine-oil changes?
Yes. SHARK 6 is a PHEV with a combustion engine, so it has engine oil and an oil filter. The electric drive components do not use engine oil, but the combustion engine does.
How often is the engine oil changed?
After the first maintenance, the Australia handbook lists engine oil and oil-filter replacement every 12 months or 10,000 km of HEV mileage, whichever comes first.
What does HEV mileage mean in the maintenance schedule?
The handbook uses HEV mileage for several engine-service rows. It is not automatically the same as total odometer mileage, and owners should check the vehicle display/manual and confirm the value with BYD.
Is HEV mileage the same as the odometer?
Do not assume that. The handbook separately references Total Mileage, HEV Mileage and EV Mileage display values. Use the correct value for the row being serviced.
Does SHARK 6 have an oil filter?
Yes. The first maintenance includes engine oil-filter replacement, and later engine oil service also includes the oil filter.
When is the engine air filter replaced?
The Australia handbook lists first replacement at 18 months or 13,500 km of HEV mileage, then every 24 months or 20,000 km of HEV mileage, with earlier inspection/replacement under dusty or severe use.
When is the fuel filter serviced?
For the non-integrated fuel filter, the handbook lists first check/replacement at 18 months or 13,500 km of HEV mileage, then replacement every 24 months or 20,000 km of HEV mileage.
When is coolant replaced?
The handbook lists long-life organic-acid engine coolant and drive-motor coolant replacement every 4 years or 100,000 km, whichever comes first.
What maintenance does the hybrid system need?
It includes service-only checks of HV battery exterior structures, HV distribution components, connectors/harnesses, charging connector, software/fault-code status, drive gear oil, differential oil and hybrid transmission filter items.
What are severe-use conditions?
They include cold short HEV trips, long low-speed creeping, dusty or salty roads, rough/mountain roads, frequent braking, towing, commercial use, high-temperature urban use, sustained hot high-speed driving and overloading.
Can I use the Australia schedule in another country?
Not without confirmation. A Russian or Armenian page is a language version, not a Russia or Armenia market schedule. Use the manual supplied with the vehicle or confirm the VIN with BYD.
Does towing require more frequent maintenance?
The handbook treats frequent towing as a severe operating condition. Use BYD service advice for the affected rows instead of applying one universal shortened interval.
Can I service the SHARK 6 myself?
Owner-safe checks are limited to items such as tire pressure, visible leaks, warning messages and manual-approved level checks. HV, brake, coolant, fuel, transmission and diagnostic work should go to authorised service.
Can missing a service affect warranty coverage?
It can create service-history problems, but warranty outcomes depend on market terms and the specific case. Keep records and confirm requirements with BYD or an authorised service centre.
