You’ll find useful resources on this page, tips, links to tools, parts and supplies required to complete your repair. Engine oil for any engine is important, the quality and the quantity.
Oil is critical because it cools and lubricates the internal components, less oil means higher internal temperatures and when the temperatures get too high, the components fuse together, this is known as seizing and for an engine that’s as bad as the story gets.
But too much oil is bad too, most mower engines use a splash method of coating the internal components. A paddle strikes the surface of the oil and splashes it about. If the oil is too full, the paddle no longer splashes as it’s submerged in oil. To make matters worse, the submerged paddle aerates the oil which reducing its effectiveness.
It’s easy to overfill oil level, most mower engines only take (from empty) .65 quart (.61 lt.) Common symptoms of too much oil include: oil leaks; no starts; white smoke; stiff pull cord.
Briggs & Stratton – Most models take from empty .65 US quarts (.6 lts) 5W30 engine oil.
Honda engines – Most take from empty .58 US quarts (.55 lts) of 10W30 engine oil.
Kawasaki engines – Most take from empty .6 US quarts (.6 lts) 10W30 engine oil.
Kohler engines – Most take from empty .6 US quarts (.6 lts) 10W30 engine oil.

Tools & Parts
To nail this procedure you may need the following tools, parts and supplies.
Ratchet Tool Set
Before we can do anything, we'll need tools. I've selected this set as I own some Craftsman tools and while I have worn some out, they did do a lot of work. So I expect this set will last the occasional user quite a long time.
This set carries both metric and standard sockets and that's important, because some mowers will have both type of fastener sizes. Set includes spark plug sockets. Picture links to Amazon.com
