My Redmax 6200 Blower requires 32:1, But my Shindaiwa T-230 requires 50:1. It seems that all manufacturers are going to 50:1 and I would imagine this is to satisfy the govt. on emissions. Aside from emissions would it be OK to run both at say 32:1 or 40:1 for sake of convenience (one fuel container)? Would'nt want to burn anything up !!! Your opinions are appreciated !!
