Hello All, I am a new member (senior citizen but who's counting years anymore) but been lurking for sometime. I have a brand new Husqvarna TS142 riding mower with the BS 18.5HP single cylinder. I am looking to do my 1st oil change at the end if its 1st season soon with 20 hours on the clock. From posts on this board I bought a Fram TG3614 silver filter and oil. My question is of the oil I bought, Super Tech 15w40 CK-4. Did I make the right choice of oil for this engine?? Lastly, the spec sticker under the hood say 64oz?? I thought more like 48oz for the oil change with filter. Need advice please on all questions..... Thanks Folks
