Honda CB1100 Engine Oil Capacity and Best Oil Specifications

The Honda CB1100, introduced in 2010, pays homage to the iconic CB750. It’s a 1,140 cc air-cooled inline four-cylinder naked bike. Initially available in Japan, Australia, and New Zealand, it reached Europe and the US in 2013. The 2014 revision added a sixth gear and new gauge cluster. The CB1100 Deluxe offers upgrades like a larger fuel tank and ABS, while the EX variant adds wire wheels. In 2017, the sportier CB1100 RS hit the market, featuring LED lights, revised engine, and sport-oriented enhancements. Production ended in 2022. The guide below is intended for the Honda CB1100 production year 2017-2022.

Checking the Engine Oil 

1. If the engine is cold, idle the engine for 3
   to 5 minutes. 
2. Turn the ignition switch to the OFF
   position and wait for 2 to 3 minutes. 
3. Place your motorcycle on its center stand
   on a firm, level surface. 
4. Check that the oil level is between the
   upper level and lower level marks on the
   oil level inspection window.
   
   ▶If required, clean the inspection
   window by turning the wiper.

Adding Engine Oil 

Engine oil consumption varies and oil quality deteriorates according to riding conditions and time elapsed. Check the engine oil level regularly, and add the recommended engine oil if necessary. Dirty oil or old oil should be changed as soon as possible. 

Selecting the Engine Oil 

For recommended engine oil

If you use non-Honda engine oil, check the label to make sure that the oil satisfies all of the following standards: 

● JASO T 903 standard*1: MA
● SAE standard*2: 10W-30
● API classification*3: SG or higher
*1. The JASO T 903 standard is an index for engine oils for 4-stroke motorcycle engines. There are two classes: MA and MB. For example, the following label shows the MA classification. 
*2. The SAE standard grades oils by their viscosity.
*3. The API classification specifies the quality and performance rating of engine oils.
Use SG or higher oils, excluding oils marked as “Energy Conserving” or “Resource Conserving” on the circular API service symbol.

If the engine oil is below or near the lower
level mark, add the recommended engine oil. 

1. Remove the oil fill cap. Add the
   recommended oil until it reaches the
   upper level mark.
   
   ▶Place your motorcycle on its center
   stand on a firm, level surface when
   checking the oil level.
   ▶Do not overfill above the upper level
   mark.
   ▶Make sure no foreign objects enter the
   oil filler opening.
   
   ▶Wipe up any spills immediately. 
2. Securely reinstall the oil fill cap.
   
   NOTICE
   Overfilling with oil or operating with insufficient
   oil can cause damage to your engine. Do not mix
   different brands and grades of oil. They may
   affect lubrication and clutch operation.
   For the recommended oil and oil selection
   guidelines, see “Maintenance Fundamentals.”

Changing Engine Oil & Filter 

Changing the oil and filter requires special
tools. We recommend that you have your
motorcycle serviced by your dealer.
Use a new Honda Genuine oil filter or
equivalent specified for your model.
NOTICE
Using the wrong oil filter can result in serious
damage to the engine. 

1. If the engine is cold, idle the engine for 3
   to 5 minutes. 
2. Turn the ignition switch to the OFF
   position and wait for 2 to 3 minutes. 
3. Place your motorcycle on its center stand
   on a firm, level surface.
4. Place a drain pan under the drain bolt. 
5. Remove the oil fill cap, drain bolt, and
   sealing washer to drain the oil.
   

6. Remove the oil filter with a filter wrench
   and let the remaining oil drain out. Make
   sure the prior seal is not stuck to the
   engine.
   
   ▶Discard the oil and oil filter at an
   approved recycling center.
   

7. Apply a thin coat of engine oil to the
   rubber seal of a new oil filter.
8. Install the new oil filter and tighten.
   

   Torque: 26 N·m (2.7 kgf·m, 19 lbf·ft) 

9. Install a new sealing washer onto the
   drain bolt. Tighten the drain bolt.
   

   Torque: 30 N·m (3.1 kgf·m, 22 lbf·ft) 

10. Fill the crankcase with the recommended
    oil and install the oil fill
    cap.
