honestly if you were gonna be forced to run someting you get from autozone get the castrol 2t. i used that up untill i went for more power, now i use maxima super m premix
i think that oil will be fine, wouldnt be my number one choice but its fine. i mean damn i run this sh*tty poulan oil in my weedeater and chainsaw and they get abused waaaay more than my quad and ive both for a few years now. for the ole blasty i love klotz benol, run it hard and u wont get the buildups I:I
