Just shake it before you use it.
Agreed, if its been a while or its a new jug I give it a nice shake to mix it all up. For the fuel bottle a swirl or two and in it goes. Also if the fuel looks ALOT different... its prob not worth throwing into your nice $200+ engine... just me, rather "waste" $10 of fuel and save alot of frustration than try and "work' with crap [8D]
