I cannot find info in my manual. What kind of engine oil can I use in a Troy-Bilt Model Series 440 lawn mower?

Most of the time it's 30 W ND or Non Detergent.

Best to buy 4 cycle oil for lawnmowers.

What i am asking is how much oil do you put in:eek:

Take a look at the Sticky at the beginning of the topic. There is info about changing the engine oil.

If is a briggs mower it is usually a pint and a quarter

Just use 10 W30 or SAE 30 regular car oil that crap that the hardware stores sell you is the same thing but for a lot more cost!!
