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
no
4cycle
I have a Ryobi BC30 Brush Cutter and the manual calls for a 2 cycle engine oil for air cooled engine TCW @ 50 to 1 ratio or 2.6 oz per gallon. States do not use TCW3 for water cooled engine or automotive type oil. Hope this helps. O fern
The terms 4 stroke, and 4 cycle, have the same meaning. There is no difference in the oil.
if 4-cycle-Use Valvoline 10W-30 oil if 2-cycle-use ryobi or any other brand of 2-cycle oil
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.
The Gas/Oil ratio is 50:1
2.6 ounces of oil to one gallon of unleaded gasoline.
50:1. Be sure to use 2-stroke oil.
32:1
2.6 oz. of 2-cycle engine oil per gallon of gas.
32:1 gas/ oil I have one and the mixture was on it.
