Oil: how much and how to check
The GX160 holds 0.61 US quarts (0.58 L). Honda engines are filled to the edge of the oil filler neck with the engine level – don’t screw the dipstick in to check, just rest it in the neck. Overfilling is as bad as running low: excess oil can foul the plug and push out through the breather.
