depends on the engine but it will be on the engine block.
No... it was ran low on oil & siezed up. junk mower now.
I just changed the oil and I couldn't find a filter on it.
you mean a lawn mower right.. if so no
No. Check oil only when engine is off.
yes B&S labels oil
30 wt oil
they both use oil
Look at the engine on your lawn mower. If the engine has an oil filler tube or a "hole" with a cap on it where oil is added to the engine, it is a 4-cycle (4-stroke) engine. If there is no oil filler tube or place to add oil to the engine, then it is a 2-cycle (2-stroke) engine and the oil has to be added to the fuel.
Drain out the excess. Too much oil will damage the engine.
Engine wear and damage can occur.
Kawasaki 15 HP Ariens Lawn Mower takes 1.2 Litres of oil and maybe a little more when you change the oil filter
