Lubricants – The Correct Oil for your Machine



Komatsu genuine lubricants are designed to ensure you get the best performance from your machine. Our range of Komatsu genuine lubricants incorporates a specially formulated additive package which, when combined with the highest quality base oil, provides superior protection for Komatsu equipment.
All Komatsu machines are filled with Komatsu genuine lubricants and coolants. It is essential that customers continue to use these lubricants for replacement at the recommended intervals to ensure optimal machine life. Used in conjunction with KOWA®, a combination of these care solutions will maximise your component life.
Komatsu genuine lubricants are also ideal for use in any older model Komatsu machines, as well as non-Komatsu equipment in your fleet.
Our Range
Your choice is easy when referencing our range table below. However, if you are still unsure of what lubricant your Komatsu machine needs, try our new online guide. This interactive site will help to identify the correct genuine oil to use for any Komatsu machine along with part numbers and fill quantities. This tool will also help to identify where genuine Komatsu oil can be used in other makes and models such as CAT, Hitachi, JCB, Hyundai & Samsung, you can even check what oils to use on highway trucks. Where ever the genuine Komatsu oil can’t be used, a Castrol alternative will be listed.
