What is oil to gas ratio for a Ryobi TP30 pull start trimmer?

The Ryobi TP30 also has the model number RY52014. This 2-cycle engine uses a 50:1 gas to oil ratio. That means that for every gallon of gasoline, you need 2.6 oz. of 2-cycle engine oil. This information is available on page 9 of the manual. Manuals Lib has the manual for the TP30 trimmer here: .

I hope this helps.

Fuel mixture ratio for Ryobi SS300 weed eater

Are you sure about the model number? I see several 30CC engine string trimmers by Ryobi. Two are the Ryobi RY30040B (SS30) and a RY30544 (SS30).

For both of these models, mix a high quality 2-cycle engine oil at 2.6 oz. per gallon of gasoline to pour into the gas tank. This ratio is used in several other Ryobi string trimmer models. Many Ryobi product manuals are available here: . Most Ryobi gas powered and 40V battery-powered tools will have a model number that starts with RY. The 18 V battery powered models often start with a P.

I hope this helps. If you add a comment with the actual model number, I may be able to provide more information.

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.
(128 oz.)
(160 oz.)
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

Have lost instuction manual. Need to know oil/gas mixture for leave blower Model RY09550

Your Ryobi should take a 50:1 mixture. In the USA, that is 2.6 ounces of 2 cycle oil per gallon of gasoline. I strongly recommend to buy 2 cycle mix that has fuel stabilizer in it. It would come in a 3.2 ounce bottle and mix 1 bottle per gallon.
Good luck!

How do I change one gallon of a 50:1 gasoline mixture to 40:1?

  • 40:1(gasoline:oil) ratio requires 3 ounces of oil.
  • 50:1(gasoline:oil) ratio requires 2.6 ounces of oil.

  • So for you to change to 40:1 you need to add .6 ounces of oil
