I don't know where it was, but on some forum or other I do recall reading less than stellar reviews of Optimas, which I found surprising based on what I knew of their reputation. If I remember where, I'll post it, but I suspect you're right anyway that this particular issue was a fluke. Or it's just the fact that it was Rich's car. ;-) I did, however, appreciate him oil-slicking the a-hole who was tailgating me.
