2023 Honda CRF300L

This is a step-by-step guide to changing the oil and oil filter on a Honda CRF300L. It is based on the author’s observations and experience changing the oil and oil filter on a 2023 Honda CRF300L and on information contained in the official Honda CRF300L service manual, 2021 (no. 61K9903) which covers model years 2021 - 2022. The author is not aware of any mechanical changes to the CRF300L for the model years 2023-2024, so this guide should apply to those as well.

Disclosure: While the author has attempted to provide correct and complete information, sometimes errors or omissions may occur. By using this document and following the procedures and advice below, the user assumes all risk and responsibility for injury or damage to their motorcycle. The author has been servicing motorcycles for many years (not as a profession) and is mostly self-taught (no formal training in motorcycle servicing). It is recommended that you consult the Honda CRF300L owner’s manual and/or service manual.

By learning to change the oil and oil filter, you can save money, learn more about your bike, gain the satisfaction of maintaining your bike yourself, as well as saving yourself a lot of inconvenience. There is nothing technically challenging about the procedure. Use the correct tools and supplies for the job, and take your time. Read all of the instructions before beginning.

Service manual instructions

There is very little in the way of instructions in the CRF300L service manual (unlike the other Honda service manuals that I have). I will supplement what there is with instructions from the 2011-2012 Honda CBR250RA service manual as the CRF300L motor is closely related to the CBR250R motor (they share a lot of the same parts). The CRF300L owner's manual does not provide any instructions for changing the oil.
