I've been running bio for 3 years without any issues
Got to keep an eye on the fuel filters once you get to the bottom of the barrel if you pump um dry you can see some crud at the bottom, Just as in any tank's
Tiny bit of power loss is normal, But I dont even notice it..
And depending on where you live, Climate/temp can be a problem, any thing below 30's for too long, you have a good chance of hard starts, or no starts due to jelling of fuel
If you can make it, Its cheap, And you can feel good about 85% less pollution
