Setup, Compatibility & Care
Before performing an oil change, ensure the lawnmower engine is slightly warm but turned off to allow the oil to drain freely. Always consult your specific Hayter model manual to confirm the correct oil capacity, as overfilling can cause smoking and engine damage. Use a clean funnel to prevent debris from entering the oil reservoir. Store the remaining oil in a cool, dry place with the cap tightly sealed to prevent contamination from moisture or dust. This oil is fully compatible with Spirit and Harrier models, but you should verify your specific engine series manual to confirm SAE 30 is the recommended viscosity for your local climate conditions.
