Fuel mix for Scrub Warrior is same as most small 2-Stroke engines - 25:1. This means 25 part fuel to 1 part 2-Stroke Oil. So 5 litres of fuel (unleaded petrol or gas as they say in the USA) needs 200ml of Oil. Some 2 Stroke oils (eg from Stihl) are designed for 50:1 mix (less pollution and plug fouling) - so read the oil container first and follow those instructions. We should not use petrol/gas older than 12months as it makes tools harder to start. If you don't have any (USA) "Aerostart" or (Aussie) "Start-You-Bastard" get some to spray into airfilter as they really make starting easier!
The Gas/Oil ratio is 50:1
2.6 ounces of oil per gallon of gas. A 50 to 1 ratio.
2.6 ounces of oil to one gallon of unleaded gasoline.
The Ryobi 725R trimmer typically requires a fuel-to-oil ratio of 50:1. This means you should mix 2.6 ounces of 2-cycle engine oil with 1 gallon of unleaded gasoline. Always ensure to use a high-quality, low-ash 2-cycle oil for optimal performance and engine longevity.
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.
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.
5 oz. per gal- or one of those little containers of the oil which is pre-measured for 1 gal..
91 octane 32-1 ratio
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.
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
Ryobi trimmers typically use a 2-cycle engine oil if they are gas-powered models. This oil should be mixed with gasoline in the ratio specified in the owner's manual, often 50:1. For electric models, there is no oil required, as they are powered by electricity rather than gasoline. Always refer to the specific model's manual for the correct type of oil and mixing instructions.
How to get rid of wallpaper glue 1. You get a bucket and fill it with water and bleach. The ratio is 1 gallon of water to one cup of bleach. You get a scrub brush and scrub until you cannot see or feel any more glue. 2. Mix water and vinegar. And do the same thing with the scrub brush. The vinegar is non-toxic but it just has a very strong smell.
