Just bought a new Toro 20092 today. It has Briggs 30 in it now.
Had my 1973 John Deere (McLane) edger serviced while I was on vacation. It has Briggs 30 in it.
When I change them in mid-summer, both will get Pennzoil 30.
Well, I lied. Just did the first oil change on the new Toro (between 5-6 hours) of use, as directed in the manual. Lot of nasty stuff came out with that used oil. I replaced it with Opti-4 SAE 30 oil. I have a 6-pack of this oil and will use it until it is gone (about 3-years worth) if I change the oil once per year on the mower and edger.
