Petrol & Diesel Engine Lubricant
10W40 multigrade engine oil for compatible petrol and diesel engine-driven equipment where this lubricant grade is specified, supplied in a practical 5 litre pack.
Engine Oil for Petrol & Diesel Equipment
Engine-driven compressors and industrial machinery can contain two separate lubrication systems: one for the engine and another for the compressor pump or air end.
The engine oil must therefore be selected from the engine manufacturer's requirements. Check the stated viscosity grade, engine model, operating conditions and service interval before use.
Petrol & Diesel 10W40 Engine Oil
Multigrade engine lubricant supplied in a 5 litre container. Confirm that 10W40 is the correct lubricant grade for the specific engine before use.
What Does 10W40 Mean?
10W40 is a multigrade viscosity designation. The two numbers describe how the lubricant behaves across different temperature conditions.
10W
The first part of the grade relates to the lubricant's low-temperature viscosity behaviour.
40
The second part relates to the lubricant's viscosity classification at normal engine operating temperature.
Engine Oil Is Not the Same as Compressor Oil
On an engine-driven air compressor, the engine and compressor pump are separate pieces of equipment with different lubrication requirements.
Engine Lubrication
Petrol and diesel engine oil is selected according to the engine manufacturer's viscosity and lubricant specification.
Compressor Lubrication
The compressor pump or air end may require a dedicated piston, rotary vane or rotary screw compressor lubricant.
How to Choose the Correct Engine Oil
Engine Make & Model
Identify the complete engine model rather than selecting lubricant from the machine type alone.
Required Viscosity
Check whether 10W40 is approved for the engine and the expected ambient temperature range.
Lubricant Specification
Match any required performance specification stated in the engine manual or service documentation.
Operating Conditions
Temperature, workload and operating environment can affect the lubricant recommendation and service interval.
Oil Capacity
Check the engine's oil capacity and use the correct procedure when filling or changing the lubricant.
Service Interval
Follow the stated operating-hour and calendar maintenance interval rather than changing oil solely by appearance.
Honda GX Engine Applications
The current product listing identifies the 10W40 lubricant with GX160–GX390 applications.
Before using it in a particular Honda GX engine, check the exact engine model and the applicable Honda lubrication guidance for the operating temperature and service conditions.
Engine Oil Changes & Routine Maintenance
Regular oil changes help maintain lubrication and remove aged oil and contamination from the engine.
- Follow the engine manufacturer's maintenance schedule
- Check the oil level using the stated engine procedure
- Use the correct lubricant grade and specification
- Do not overfill the engine
- Inspect for leaks around seals and drain points
- Keep dirt away from the filler opening
- Use clean filling and draining equipment
- Dispose of used engine oil through an appropriate waste route
Why Correct Engine Oil Level Matters
Both insufficient oil and overfilling can cause problems. The oil level should be checked using the method specified for the particular engine.
Low Oil Level
Insufficient lubricant can reduce protection of internal engine components and may lead to accelerated wear or damage.
Excess Oil
Overfilling can also affect engine operation. Fill only to the level specified by the engine manufacturer.
Engine Oil Storage & Handling
- Keep the container sealed when not in use
- Store away from water and contamination
- Keep different lubricant grades clearly identified
- Use clean funnels and dispensing equipment
- Do not return used lubricant to a clean oil container
- Follow any product-specific safety and storage information
Need Help Confirming the Correct Engine Oil?
If you are unsure whether this 10W40 lubricant is suitable, provide the engine information before ordering.
- Engine manufacturer
- Full engine model
- Engine serial number where available
- Petrol or diesel engine type
- Existing lubricant grade
- Lubricant specification stated in the manual
- Approximate ambient operating temperature
- Equipment the engine is fitted to
- Photograph of the engine data plate
Looking for Compressor Oil Instead?
If you need lubricant for the compressor pump or air end rather than the petrol or diesel engine, choose the appropriate compressor lubricant range.
Petrol & Diesel Engine Oil FAQs
What is 10W40 engine oil?
10W40 is a multigrade engine-oil viscosity classification designed to provide defined viscosity behaviour across lower and normal operating temperatures.
Can I use 10W40 in any petrol or diesel engine?
No. Use 10W40 only where the engine manufacturer permits that viscosity and the lubricant also meets any required performance specification.
Is engine oil the same as air compressor oil?
No. Engine oil and compressor lubricant serve different equipment and should not be treated as interchangeable unless the relevant manufacturer specifically approves the lubricant.
Does this oil suit Honda GX engines?
The product listing identifies GX160–GX390 applications. Confirm the exact engine model and current manufacturer lubrication guidance before use.
How often should engine oil be changed?
Follow the engine manufacturer's stated operating-hour and calendar maintenance intervals, with additional consideration for severe operating conditions where applicable.
Can I mix different engine oils?
Mixing should not be assumed to be suitable. Confirm that the oils meet the required specification and are compatible before topping up or changing lubricant type.
Can Compressed Air Systems UK help identify the correct lubricant?
Yes. Provide the engine make, model, existing oil information and a photograph of the data plate and our team can help check the appropriate lubricant.
