The manual recommends Lucas oil, which is what I use. I use the 30 oil, but you could use 10W-30. http://lucasoilstore.com/store/index.php?main_page=product_info&cPath=89&products_id=743&zenid=b07fc91b0f62e86b02a2bf116fa2f23d
4-cycle oil. Whenever there is a separate cap for oil on a lawnmower, that machine takes 4-cycle oil. When you have to mix the oil with the gas in the same hole, that machine requires 2-cycle oil.

It surely depends on the type and size of lawnmower. This question is therefore impossible to answer.
If the lawnmower has two compartments one for gas and the other for the oil, then put gas in the gas and a 30w type oil in the oil compartment. Simple as that. If you have an engine with only one compartment then you'll need to check on the manufacturers suggestions which is usually 40:1 or something close.
for oil change it takes 18 oz of 5w30 per manual
That will depends on the manufacturer and model of transaxle that is under the mower.
