Which model did you get? I ordered a Toro 821 QZE.Machine arrived and was a rather straightforward put-together. The included oil was labeled Toro premium and met certifications SG, SH, SL. Didn’t pour like synthetic and the front of the bottle proudly stated “ contains Zinc additives”.
There was NO owners manual! A three page pamphlet of pictures for basic assembly was included, and I found the Toro manual downloadable on the seller’s website. Manual stated just as all of you did - available 5w30 synthetic or Dino.
Thanks for al the thoughts.
