As the engine is "of old design" i decided to go for an oil designed for motorbikes. Halfords 10w40 4stroke oil semi synthetic.



Run the engine for about 10 mins as warm oil flows better than cold. Place a suitable container under the drain plug and using a suitable 17mm socket or ring spanner remove the plug.

Whilst the oil is draining remove the oil fillercap/dip stick.

Cover of oil filter/strainer

The above picture shows the location of the oil filter/strainer cover. You will require a 23mm socket or spanner to remove. There is a spring under the cover to hold the filter in place so beware when removing the cover.

Cover removed. spring and filter in position.
