Mostly highway miles running about ten over the speed limit. I do enjoy full throttle acceleration. Have been running Renewable Lubes's fuel additive, about 25% of the time, in mostly Shell 87. Air filter is Amsoil EAA and oil filter is EaoM. Shifting got a bit notchy in last 500 or so miles. I figure that is when the oil started to break down.
Not going to share Terry's comments, but I will say that the glycol is not antifreeze.
First interval is suspected to be Honda 10W30 with AutoRx for the last 1,000 miles. Had the Honda air and oil filters.
