My Ryobi 725r (multi attachment) requires a 32:1 fuel oil ratio. The owners manual calls for a 4oz bottle of oil per gallon of unleaded fuel. I had been buying other brands for my oil but recently found out that they are only 3.2oz of oil. Ran my weedeater for at least two years with that mix and have not had any problems with it. I would say it's best to use the manufacturers specs though.

Oil petrol mixture for Rockwell 26cc weedeater


Two cycle engines run on a mixture of gasoline and oil. Each engine type is designed to run on a specific gas-to-oil mix ratio.
IMPORTANT: Use only oil that is labeled for use in "Two-cycle" or "Two-stroke" engines. Home Depot and other stores now have "premixed fuel" of gas and 2 cycle oil.
To mix two-cycle fuel, start by putting correct amount of oil in gas can. Then slowly add correct amount of gasoline. Do not try to mix gas and oil directly in gas tank of equipment.

IMPORTANT: Do not use any fuel that is over 30 days old. Do not mix more fuel than you are likely to use in a month. Old fuel can gum carburetors and prevent starting. Always use fresh fuel.

The chart below shows correct amount of oil per gallon that each mixing ratio requires. Expect that yours will be between 32 gas to1 oil and 50 to 1. 32:1 and 50:1 are most popular.
Ratio GAS:OIL UNITED STATES OIL per 1 U.S. GALLON Gasoline
(128 oz.)
*INTERNATIONAL OIL per 1 IMPERIAL GALLON Gasoline
(160 oz.)
*INTERNATIONAL OIL per 1 LITER Gasoline
(metric)
32:1 4 oz. 5 oz. 31.25 mL 40:1 3.2 oz. 4 oz. 25 mL 50:1 2.6 oz. 3.2 oz. 20 mL

Need to know the gas:oil ratio for weedeater FL1500


100 ml of 2cycle oil to 4000 ml of fuel..Which is 40/1 ratio
100 ml of 2cycle oil to 5000 ml of fuel.. which is 50/1 ratio

4 o/z is 118.29411875006815 ml to 1 gallon of fuel (3.79 litres or 3790 ml) Which means 32/1 ratio...I find that to confusing,so it is easier to say 100 ml of oil to 3200 ml of fuel ===32/1.

What is the oil/gas ratio for a Ryobi RY30550 weedeater? 50:1? Thanks


50:1 is too high. That is normally for a chainsaw which is much more severe duty. Normally for a weed whip its 25:1. They usually say on the gas cap but if not 25:1 is a good ratio that never fails (have done commercial landscaping for years) I use this ratio if I don't have a guide from the manufactor of the weed whip..

What is the gas to oil mixture ratio for a GTI15 weedeater?


40:1 is the recommended ratio by the company that made the weedeater. But it has been my experience that 32:1 allows the engine to last longer.
