Today I changed the oil and the filter oil , and I use mineral oil 10w40 , only I don't know if I have one problem or it's normal . When I check the oil level with engine off the level oil it's close to maximum (a little bit down ) but with engine running it's a little bit over the minimum level . I put in the engine 2 liter because I change also the oil filter , it's normal to be like that ?

Yes, That's normal.
Don't worry!
