Use SAE 15W40 4-stroke engine oil.
You can buy cheap 240V petrol generators for around $500 these days, but they are inefficient, noisy and dangerous. Not dangerous for you, but for your 240V appliances. The problem is that due to their rudimentary output regulation, when they are working below the rated load of the generator the line voltage can increase from a nominal 230/240VAC to over 260VAC (in some cases up to 400VAC)! It is for this reason that I have listed this item for $700 and is selling at JAYCAR for $999. This has never been used and is brand new with original box.
This inverter generator unit is petrol powered and differs from cheaper units, in that the engine (which is built to the same design as the market leading Japanese brands) drives a DC alternator. A pure sine wave inverter then converts the DC to a stable pure sine 230VAC, suitable for appliances including sensitive electronics. No matter what the load is on the generator, the output remains at 230VAC 50Hz. The added benefit is that the petrol motor is far better matched to the load, reducing overall size, keeping engine speed in line with the load, reducing noise and increasing fuel efficiency.

Note: Powertech portable inverter generators are supplied dry, meaning that there is no oil or petrol in the engine. Engine oil MUST added before use or damage will result. The engine uses commonly available SAE 15W40 4-stroke engine oil as per the instructions (Will deliver for the right price)
