Hello fellow punters - I own a Scott Bonnar reel mower model no 590. Without the benefit of an owners manual, I am a bit in the dark in regards to what type of engine oil needs to be used, and also how much. In terms of how much oil to add, is there a dipstick test that you can use to determine if the oil is at the correct level?

I used a thin wooden meat skewer to check the level and the oil level showed approx 3/4 inch up the skewer. Any advice on this would be welcomed.

Regards
Pat
