Refrigerant gas cylinder R404A is a lubricant or service fluid: it reduces friction, carries heat away and protects the engine or circuit it is used in.
The specification matters more than the brand. Oil with the wrong viscosity or a service level below what the engine calls for accelerates wear even when changed on time.
Specifications and compatibility
This item is supplied against the equipment reference; confirm the application from the set nameplate before ordering.
How to verify before ordering
- Match viscosity grade (for example 15W-40) and the API service level the engine requires.
- Check pack size against sump capacity so you are not short on the fill.
- Confirm the product is for heavy-duty diesel engines, not a petrol formulation.
Frequently asked questions
How often on a set that barely runs?
At least once a year, even without reaching the hours. Oil oxidises and collects moisture; an oil analysis confirms condition before you decide.
Can it be mixed with another brand?
Only if both meet the same specification and viscosity. Mixing different formulations can gel additives and reduce protection.
