Briggs straitton
I've always used " regular " unleaded gasoline , 87 octane , in my 5 horsepower Tecumseh engine on my snowblower and my 4 horsepower Tecumseh engine on my lawn mower
30 wt oil
Depends on the brand mower the engine is installed on. More than likely any standard 12V lawn mower battery will fit.
The Make of the Engine is Tecumseh. I am still trying to find the enige number for it though...
I am trying to find the same answer to this at http://www.answerblip.com/tecumseh-push-mower-engines
The engine on mine is labelled "Tecumseh", but a paper tag that might have had a model number has worn off.
SAE 30 full synthetic oil, any major brand.
It depends on how old this particular mower is, and how large it is! Older and larger ones used to have Tecumseh motors, but tecumseh went out of business. Older and Newer smaller Troy Bilt's have had Briggs & Stratton, for some time, but depending on the durability model and how new it is; It may have a Honda motor.
Briggs and Stratton does contract anyone to build mowers. The mower manufacturers contract Briggs and Stratton to build their engines (or whatever engine is on the unit). That is why you can have a Briggs and Stratton on most any type of mower. Same is true for Kohler, Tecumseh, etc. Not to say that the engine manufacturers do not build their own type of outdoor power tool but as the question states "snapper mower". Also keep in mind that if you have a snapper mower with a Briggs and Stratton engine and you need warranty work on the engine you need to go to an Authorized Briggs repair facility where as if you have a mower warranty then you need to go to an authorized repair facility for the mower manufacturer.
30 wt of a good brand if it is a Briggs or Tecumseh.
Depends on what type of engine it has. If it is a Briggs and Stratton or Tecumseh, then use 30 weight oil. If its honda, use 10w30
