Sorry for the delay in information, work really interferes with life.
In response to Rod Knox,…yes, there was residue on the dipstick. I checked the oil on the side of the road, expecting it to be low. When I initually wiped the dipstick, it was sticky with a burnt oil residue all the way up (the tube length). It confused me at first, but is obvious in hindsight. (Foam and heat)
Anyway, Mr. Popular National Chain Manager is flaunting his ASE credentials and has blown me off completely. (Not even a refund for the oil change.) Fortunately, local small claims court has a $6k limit and 2yrs statute of limitations. More to come in a few months after my court appearance. If anyone knows of information that will support my position in court, it would be greatly appreciated. People need to know they have recourse.
Thanks to all who have reponded.
