Beating a dead horse here, but I don't even read any oil related threads on any of the other automotive forums I frequent. Mis-information and half truths, etc. run amok. I guess I shouldn't let it bother me too much. These fools are just missing out on some excellent oil and are really too lazy to come to this site and learn something. Typical behaviour of Zipper Heads.
But I started thinking about the time frame that all the talk about waxy build up starts and it seems like it started happening in "the old days", perhaps in the 1960's.
This got me thinking further and I recall there were two kinds of Pennzoil back then. One had the red band and red labeling on the top of the can; the other kind had the black band and black labeling.
My father told me that the red labeled can was the HD oil and contained detergents. The black labeled can did not contain detergents. Dad does not pretend to be an oil expert either. He could be wrong.
But I wonder if all the wax build up stories/myths are because people were using the non-detergent oil?
