This is a total myth. The poor quality is in the car, not in USA fuel. Daimler has great engineers who were responsible for building the 3.0 and 3.5 engines. However, an engineer can draw up the blue prints to send a man to Pluto, but if somebody attempt to use cardboard and newspaper or even stronger, plastic, to get to Pluto; you can bet on not making it no matter how great and accurate and ingeniuos the designs are.

The USA fuel myth is like superstitions, where when you don't know for sure; you can just about believe anything.

Daimler doesn't know the causes for the failures itself because they sublet the building of the cars to such a sever degree that noboby knows how all of the parts fit together and that is by design. No good intentioned builder of cars would put a $2.00 part on the car in critital areas that will make the car inoperable if the $2.00 part fails, espcially on a $100,000.00 car. Daimler could have used platinum instead of many of these $2.00 parts and still made money, especially in USA models loaded with $2.00 parts.
