Toxic 2u No i have never read the bottle of traxxas fuel cause i dont use it and there's a reason y i dont. He's using sidewinder fuel and the fuel that he's running is fine. I ran my traxxas engine with racing fuel that has 8% oil content in it and it has more then 8 gallons through it now. And by the way i do know what im talking about i have been in this hobby for a little while now Im not saying that u dont have more time then me in this hobby. He never said he was running a trx engine so all we know he's running another engine in his rusty. We just simply dont know.
