FAQs

What type of engines is Mountfield MX855 oil suitable for?

It is suitable for all 4-stroke petrol engines where an SAE-30 or 10W-40 viscosity is recommended. It is not for 2-stroke or diesel engines.

How much oil do I need for an oil change?

The exact amount varies by machine. Consult your equipment's manual for the precise oil capacity. This 1-litre bottle is often sufficient for a single oil change or top-up.

Can I use this oil in my Mountfield lawnmower?

If your Mountfield lawnmower's manual specifies SAE-30 or 10W-40 oil for its 4-stroke engine, then yes, this oil is suitable.

What is the difference between SAE-30 and 10W-40?

These are viscosity grades. SAE-30 is a single-grade oil, generally suited for warmer temperatures. 10W-40 is a multi-grade oil, offering better performance in a wider range of temperatures, particularly in colder conditions.

How often should I change the engine oil?

Refer to your equipment's manual for the recommended service interval, typically based on operating hours or seasonally (e.g., annually).

Can I mix this oil with other brands or types of oil?

It is generally recommended not to mix different types or brands of oil to ensure optimal performance and avoid potential chemical reactions. If changing oil types, it's best to drain the old oil completely.

Troubleshooting

Engine oil level is too low

Add the recommended type and viscosity of oil (Mountfield MX855 if suitable) gradually, checking the level with the dipstick after each small addition. Do not overfill.

Engine runs rough or makes unusual noises

Check the oil level. If low, top up as instructed. If the oil level is correct, the issue may be unrelated to lubrication and requires further mechanical inspection.

Oil appears milky or frothy

This can indicate water contamination. The engine may need to be drained and refilled, and the cause of water ingress investigated.

Pros and Cons

Pros

  • Versatile compatibility with multiple engine types.
  • Provides excellent lubrication for engine longevity.
  • Meets common SAE viscosity standards.
  • Convenient 1-litre packaging for DIY maintenance.

Cons

  • Requires user verification of specific engine oil needs.
  • May not be suitable for engines with highly specialized oil requirements.
  • Mineral oil base might be less performant in extreme temperatures compared to full synthetics.

Setup, Compatibility & Care

Compatibility:

  • This oil is specifically for 4-stroke engines only. Do not use it in 2-stroke engines or diesel engines.
  • Verify your equipment's manual to confirm if SAE-30 or 10W-40 viscosity is recommended.
  • Suitable for most lawnmowers, rotavators, and other garden machinery requiring these oil grades.

Care & Maintenance:

  • Always ensure the engine is cool before checking or adding oil.
  • Use a clean funnel to avoid contamination when filling.
  • Wipe up any spills immediately to prevent damage to surfaces.
  • Store the oil bottle in a cool, dry place away from direct sunlight and extreme temperatures.
  • Dispose of used engine oil responsibly according to local regulations.

Checking Oil Level:

  1. Ensure the lawnmower is on a level surface.
  2. Locate the oil dipstick (usually yellow or red).
  3. Unscrew and remove the dipstick, wipe it clean.
  4. Reinsert the dipstick fully, then remove it again.
  5. Check the oil level against the marked indicators on the dipstick. Add oil if below the minimum mark, being careful not to overfill.
