32:1 gas/ oil I have one and the mixture was on it.
Most any brand of two cycle oil. Most come in bottles that mix with a gallon of gas.
20w/50 is what comes with the 4-cycle string trimmer. While Home Depot is the sole distributor of Ryobi tools, they do not have the oil in Montgomery, AL
The ratio of gasoline to oil is usually written on the fuel cap or on a sticker nearby. The one I have is 32:1.
5 oz. per gal- or one of those little containers of the oil which is pre-measured for 1 gal..

About 5 oz. to a gal. One of those little bottles of oil they sell is supposed to treat a gallon. You can find in any hw store.
You should oil your trimmer every other time it is used to keep it running smoothly.
If the Ryobi is a 2 stroke engine you must use 2 stroke oil and never use 4 stroke. But you ask about 20w50 oil which is confusing. 2 cycle engine do not use multi-vicosity oil. Any 2 cycle oil can be used in your Ryobi if it is mixed at the correct ratio.
