I have the exact same mower and I use mobil 1 5w30 and it seems to work
what kind of oil for a sears push mower and how much?
Lawn Mower
If all oil the mower will not start. If only a little oil, the mower may start but run rough and smoke very much.
20oz
Drain out the excess. Too much oil will damage the engine.
cross reference MTD 951-12690
That would depend entirely on the particular Toro mower you're referring to.
The Honda Black Max self-propelled mower sold a Sam's Club is made by Husqvarna Outdoor Products. No mention in the owner's manual, but the deck plate has an HOV label and the oil that comes with the mower is HOV 4 cycle oil and the label on it states that it is made by "Husqvarna Outdoor Products".
about 78 gallons
approx 20oz
One should first start the mower and let the oil get warm. Doing this will ensure that not much of the old oil is left in the tank. Next place an oil pan under the mower to catch the oil and then pull the plug pin. Let the oil drain out and then put the cap back in place. Refill the mower with new oil and the job is done!
