Thus you have a fairly significant shift in fuel chemistry. The sulfur-aromatic compounds used to "alloy" with some of the metal surfaces to create soft, low wear faces, but now you do not have this as much, thus the wear. The change in chemistry to remove the sulfur also changes the solvency parameters, both solving junk and gunk, as well as sometimes rubber parts as well.

Thanks for the in depth. Im still looking through the dictionary to try and decipher it  What your basically saying is the same thing that happened when they removed lead from gas to the valve seats is basically happening to our injectors , pumps , etc. The fuel is also becoming more caustic thus cleaning the tanks as whunter posted and possibly eating the rubber ? Do I get a E for effort ??
