Triumph Street Scrambler - 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 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 oil and oil filter in accordance with scheduled maintenance requirements.

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 your 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 plug
2.  Sight glass
3.  Maximum limit
4. Minimum limit

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

Note the oil level visible in the sight glass.

When correct, oil should be visible in the sight glass at a point midway between the upper (maximum) and lower (minimum) markings on the sight glass.

Note:

An accurate indication of the level of oil in the engine is only shown when the engine is at normal operating temperature and the motorcycle is upright (not on the side stand).

If it is necessary to top up the oil level, remove the filler plug and add oil, a little at a time, until the level registered in the sight glass is correct.

Caution

Make sure no foreign matter or contamination enters the engine during an oil change or top up.

Contamination entering the engine may lead to engine damage.

Once the correct level is reached, fit and tighten the filler plug.

Oil and Oil Filter Change

Warning

Prolonged or repeated contact with engine oil can lead to skin dryness, irritation and dermatitis. In addition, 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 filter must be renewed in accordance with scheduled maintenance requirements.

To change the engine oil and filter, follow the instructions.

Warm up the engine thoroughly then stop the engine. Secure the motorcycle on the side stand.

Allow the oil to settle for five minutes before draining.

Place an oil drain pan beneath the engine.

Remove the sump plug from the bottom of the sump and allow the oil to drain.

1. Sump plug
2.  Oil filter

Secure the motorcycle in an upright position on level ground.

Position the oil drain pan beneath the oil filter.

Unscrew and remove the oil filter using the Triumph service tool T3880313.

Dispose of the old filter in an environmentally friendly way.

Prefill the replacement oil filter with new engine oil.

Apply a smear of clean engine oil to the sealing ring of the new oil filter. Fit the oil filter and tighten to 10 Nm.

After the oil has completely drained out, fit a new sealing washer to the sump plug. Fit and tighten the plug to 25 Nm.

Remove the oil filler plug.

Fill the engine with a 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.

Do not overfill or exceed the capacities given in the Specifications section.

Start the engine and allow it to idle for a minimum of 30 seconds.

Caution

Raising the engine speed above idle, before the 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 oil to circulate fully.

Make sure that the low oil pressure warning light extinguishes shortly after starting.

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.

Turn the ignition OFF, check the oil level using the method previously described, and top up to between the minimum and maximum level lines in the sight glass.

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 watercourses. Do not place used oil filters in with general waste. If in doubt, contact your local authority.

Oil Specification and Grade

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, nondetergent 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 up.
