Snake oil ? has been asked many times, you will get both sides and you will have to decide.
I would recommend going with a thicker oil and using slower RPM's.
I bought a new lawn mower and from day one it used oil. Sounded to me like they had the governor set to hi. With no tack, I just slowed the motor a little and it stopped using oil.
A quart on oil in 10 hours isn't that bad. Look at your plugs for oil deposits and soot. It will take many quarts of oil to pay for a rebuild.
I have a motor that doesn't use a drop of oil in 75 hours, then it starts using oil. Something breaks down in the oil after 75 hours. Time to change oil.
First slow down, use a thicker oil, make sure carb is lean as possible, no black soot on plugs, and then if you want add snake oil to see if there is any change.
