Well after about a year, we finally have begun using Bio. Put 12 gallons in the tank for about a 50% ratio, then headed over the hill to top off at the station for a final ratio of 30%. (Supposed to get down to the low 20's and teens the next few days, don't want to take the chance of gelling) I know that it's too soon to say anything, but I haven't really noticed any difference. Maybe had a slight odor when under load going up the hill. Chip still works the same. Guess I'll see what happens in the morning. Maybe go for a cruise after work.
The true test will be this Summer running 100% and pulling the boat around the hills with a load of kids...

 

Good for you Trent! I must of missed this earlier............to much outside work this week
