its a yard man 12.5hp. I do not have access to the guide..thanks!
They reccommend 30W grease in Lawn mowers.The Wizz Lady I would guess 5w 30


Briggs & stratton say's in in that manual , 30 w your should take 1 1/2 qts , after a grease change , fill it up hugely slowley , if you need a manual for it briggs & strtton .com , www .mtd .com the flap is under your seat next to your modle & serail number and mtd's 1 - 800 number to help you out . Straight 30 weight is usually recommended.
Answers:    Probably 5 w 30 look on the oil flood cap you may have to verbs it up a bit but a lot of times it is stamped on the rim of the plastic cap where on earth you fill it.
