Re: 100:1 Mix
There was a thread on this odd red color a while back and there was proof offered by one member that in different parts of the country the fuel has different additives to adjust for local climate/conditions. One of those additives was reported responsible for the red color seen by some members.
Most Opti-2 users say they see a brown color on pistons and plugs. I've been running Opti for a long time and my plugs and piston crowns are shades of grey.
Fuel additives might be the culprit in this case. Just a theory that I happen to agree with.
