I have a Rancher 445 chainsaw and an Echo string trimmer. I use the recommended Husqvarna XP 2 cycle oil in the fuel for the chainsaw. I would like to use the same gas/oil mixture for the string trimmer, but the instructions for the string trimmer specify 2 cycle oil that meets ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FC/FD specs. The Husqvarna XP 2 cycle oil does not show what specs it meets. Can you tell me if the Husqvarna XP oil meets those specs? thank you
