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

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: https://www.ryobitools.com/power-tools/support/manuals . 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.

You have a hairline leak in one of your hoses or a small gasket under primer bulb.

if you are using stihl oil the ratio is 50:1

Mixture is typically 40 or 50 to 1, gas to oil. The exact mix should be stamped on the gas cap.

The window ratio should be fine between 40/1 to 50/1.

Reduce oil ratio by increase gas part if some unburned oil can visible from the exhaust.

Someone else could have a better voice on this matter..

Hello slabieniec:

The Newer 2 Cycle Trimmers use a 50:1 Ratio (OEM Suggested Ratio). I Use a 40:1 Ratio in Most of my Equipment, Except for Chainsaws and Hole Drillers/Augers. For the Chainsaws I Use a 32:1 Ratio and the Hole Digger/Auger Uses a 25:1 Ratio.
Please, Do Not Hesitate, If you Hit a Snag or this Does Not Correct the Problem, I am Here if You Require More Assistance.
Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Be Happy. Thanks.

Good Luck

If it is a 2 stroke engine, a 50:1 ratio should work. That's 50 parts gas to 1 part oil.

50:1

Ryobi trimmers I have had use a 32:1 oil mix. Just pick up a little bottle of Ryobi 2-cycle oil and read it to see that it will give a 32:1 mix in a gallon of gas. Pour it into a gallon of gas, and maybe a little fuel stabilizer too, shake it up and you should be good for the season.
