Recommended Oil for Leaf Blower
High-quality 2-stroke oil meeting JASO FD or ISO-L-EGD standards. Most manufacturers recommend their branded oil (Stihl HP Ultra, Husqvarna XP+, Echo Power Blend).
Always Check Your Owner's Manual
Using the wrong fuel ratio can damage your engine. Professional backpack blowers like the Stihl BR 700 and Echo PB-9010 all use 50:1 ratio.
