Old TroyBuilt Rototiller with a 3.5hp Tecumseh:
Out: ??? Lord only knows it was black, thick, nasty and bleh
In: B&S SAE30 HD
Craftsman Platinum with a 725 B&S L head
Out: B&S SAE30 HD (it was burning this which really irritates me considering the mower is 1 season old -- left over old stock from 2014)
In: Mobil 1 European Blend 0w-40 (seemed like a good experiment to see if it helps with the burning)
Now the burning in the B&S engine wasn't horrible. In 25 hours it burned enough to go from full to add.
