I recently had a new engine put on my mower under warranty. Here is what I do with new engines. I got this from an old guy when I bought a new Snapper back in 1991 and it lasted 17 years so why not.
At 2 hours - drain and fill with some Valvoline SAE 30 I have laying around.
At 5 hours - drain and fill with some 10w30, then I will go with yearly changes.
I don't have any 10w30 laying around so some suggestions would be nice, keep it to 10w30 please, it's what the manual calls for and for warranty purposes I will stay with 10w30. I have be using Kohler 10w30 but open to some suggestions.
