Any body know the gas mixture for Ryoby gas trimmer BC30. My friend gave me the trimmer but no manual and I am guessing 32:1. Thanks for helping.

 

no sticker on the engine saying anything? its most likely 40:1

 

Already check, but found nothing. Is 40:1 is standard to Ryobi 2 cycles? Or specific to this trimmer?

 

don't worrry about the sticker or the gas cap. buy a quality 2 cycle oil not auto store stuff. stihl, echo, shindaiwa. husqvarna, optimol, jonsered, etc. the mix ratio depends on the oil not the machine. and never, never use outboard motor mix oil for an air cooled engine.

 

Hey Flopshot. Now you tell me. I've been using outboard two cycle oil in my chain saw, grass trimmer and snowblower for many years. No problems.

Maybe it's like the story that a bee is too heavy to fly, but since no one told it, it continues to fly. Seriously, what problem(s) do you see?

 

ask any two stroke engine mfg and they will tell you that outboard oil is formulated with the water cooled aspect in mind. and it's not a hard sell. in the same sentance they'll also tell you that many "brands" come out of the same factory. i once recieved a drop shipment of two stroke echo from the mfg and there was a pallet of stihl behind it.

 

pretty much, yes. i'd try and find a synthetic 2 stroke (air cooled formulated) oil, after i'm done with what i have right now, i'm thinking on mobils 2 stroke oil. as for using water cooled 2 stroke engine oil, it doesn't need to stand up to the heat in a air cooled 2 stroke, though i've seen it work alright in em, but stick with air cooled, name brand 2 stroke oil, 50:1, 40:1, or 32:1. 40:1 is basically in the middle of the choices, some even run 2 stroke oil to a mix of 100:1 (only synthetic oils). but 40:1 is a good reliable ratio to go with.
