Re: opti 2
I got a call today from one of the guys at the main office for Opti-2 in Blain, Washington. Those guys are All about customer service. Ended up talking for about 20 min. on the phone.
I had a question about whether it was synthetic or not. As of 2008 it is a synthetic blend. I just wanted to clarify that to a friend of mine. Any way you look at it, I love the stuff, and think I will buy a gallon with the new little pump they have that fits the gallon jug and pumps out exactly the right amount for a 1 gallon mixture, no measuring, no mess.
