How many hours do you have to have on the engine before you top it out.

 

take it easy for the first 10 hours or so... changing the oil after the first hour... then change it on the 3rd and 7th and 10th hour....
thats what i did with my 450... it sounds like alot but the predator has alot of junk that comes out in the oil.. so i suggest it.
or you can just do it after 10 like most people... but you wont like what you see in the oil... which will be alot of alluminum.
