Triumph Street Triple S - Owner's Manual > Engine Oil

Warning: Motorcycle operation with insufficient, deteriorated, or contaminated engine oil will cause accelerated engine wear and may result in engine or transmission seizure.

Seizure of the engine or transmission may lead to sudden loss of motorcycle control and an accident.

In order for the engine, transmission, and clutch to function correctly, maintain the engine oil at the correct level, and change the engine oil and oil filter in accordance with scheduled maintenance requirements.

Engine Oil Level Inspection

Warning: Never start the engine or run the engine in a confined area.

Exhaust fumes are poisonous and can cause loss of consciousness and death within a short period of time.

Always operate the motorcycle in the open air or in an area with adequate ventilation.

Warning: If the engine has recently been running, the exhaust system will be hot.

Before working on or near the exhaust system, allow sufficient time for the exhaust system to cool as touching any part of a hot exhaust system could cause burn injuries.

Caution: Running the engine with insufficient oil will cause engine damage.

If the low oil pressure indicator remains on, stop the engine immediately and investigate the situation.

1. Filler
2. Dipstick location in crankcase
3. Dipstick
4. Upper marking
5. Lower marking

To inspect the engine oil level:

• Start the engine and run at idle for approximately five minutes.
• Stop the engine, then wait for at least three minutes for the oil to settle.

Note: An accurate indication of the level of oil in the engine is only shown when the engine is at normal operating temperature, the motorcycle is upright (not on the side stand) and when the dipstick has been fully tightened.

Do not add oil through the dipstick hole in the crankcase.

• Remove the dipstick.
• The oil level is indicated by lines on the dipstick. When full, the indicated oil level must be level with the upper marking on the dipstick.
• If the oil level is below the lower marking, remove the filler plug and add oil a little at a time through the filler plug hole in the clutch cover until the correct level is reached.
• Once the correct level is reached, install and tighten the filler plug.

Engine Oil and Filter Change

Warning: Prolonged or repeated contact with engine oil can lead to skin dryness, irritation and dermatitis.

Used engine oil contains harmful contamination that can lead to skin cancer.

Always wear suitable protective clothing and avoid skin contact with used oil.

Warning: The oil may be hot to the touch.

Avoid contact with the hot oil by wearing suitable protective clothing, gloves, eye protection, etc.

Contact with hot oil may cause the skin to be scalded or burned.

Warning: If the engine has recently been running, the exhaust system will be hot.

Before working on or near the exhaust system, allow sufficient time for the exhaust system to cool as touching any part of a hot exhaust system could cause burn injuries.

The engine oil and engine oil filter must be replaced in accordance with scheduled maintenance requirements.

1. Oil drain plug
2. Oil filter

To change the engine oil and engine oil filter:

• Warm up the engine thoroughly, and then stop the engine and secure the motorcycle in an upright position on level ground.
• Place an oil drain pan beneath the engine.
• Remove the oil drain plug.
• Unscrew and remove the oil filter using Triumph service tool T3880313.
  Dispose of the old oil filter in an environmentally friendly way.
• Apply a thin smear of clean engine oil to the sealing ring of the new oil filter. Install the oil filter and tighten to 89 lbf in (10 Nm).
• After the oil has completely drained out, install a new sealing washer to the drain plug. Install and tighten the drain plug to 18 lbf ft (25 Nm).
• Fill the engine with a Semi or fully synthetic 10W/40 or 10W/50 motorcycle engine oil which meets specification API SH (or higher) and JASO MA, such as Castrol Power 1 Racing 4T 10W-40 (fully synthetic) engine oil, sold as Castrol Power RS Racing 4T 10W-40 (fully synthetic) in some countries.
• Start the engine and allow it to idle for a minimum of 30 seconds.

Caution: Raising the engine speed above idle, before the engine oil reaches all parts of the engine can cause engine damage or seizure.

Only raise engine speed after running the engine for 30 seconds to allow the engine oil to circulate fully.

Caution: If the engine oil pressure is too low, the low oil pressure warning light will illuminate. If this light stays on when the engine is running, stop the engine immediately and investigate the cause.

Running the engine with low oil pressure will cause engine damage.

• Make sure that the low oil pressure warning light remains off and the oil pressure message is not shown in the instrument display screen.
• Stop the engine and recheck the oil level. Adjust if necessary.

Disposal of Used Engine Oil and Oil Filters

To protect the environment, do not pour oil on the ground, down sewers or drains, or into groundwater sources. Do not place used oil filters in with general waste. If in doubt, contact your local authority.

Engine Oil Specification and Grade (10W/40 & 10W/50)

Triumph's high performance fuel injected engines are designed to use 10W/40 or 10W/50 semi or fully synthetic motorcycle engine oil that meets specification API SH (or higher) and JASO MA, such as Castrol Power 1 Racing 4T 10W-40 (fully synthetic) engine oil, sold as Castrol Power RS Racing 4T 10W-40 (fully synthetic) in some countries.

Refer to the chart below for the correct oil viscosity (10W/40 or 10W/50) to be used in your riding area.

Oil Viscosity Temperature Range

Do not add any chemical additives to the engine oil. The engine oil also lubricates the clutch and any additives could cause the clutch to slip.

Do not use mineral, vegetable, non-detergent oil, castor based oils or any oil not conforming to the required specification. The use of these oils may cause instant, severe engine damage.

Make sure that no foreign matter enters the crankcase during an engine oil change or top off.
