what grade of oil for Toro super recycler???
I just drained the oil out of my brand new Toro after 5h of running, as per manual, and was about to refill with the only SAE 30 oil I found at HD when I read in the manual:
use of service SF, SG, SH, SJ or higher
this oil is labeled SI, not part of this list. I don't want to buy the expensive B&S warranty certified oils or do I. Is this SI oil going to be fine and not void my warrantry?
