I've been reading with interest all the posts concerning the sulfur smell some owners are experiencing.
I found the following on the Sunoco Web site. It indicates that EPA regulations will require the sulfur content of gasolines to continue to go down in 2006. Hopefully this will be good for those experiencing problems. Here is a quote from the Sunoco Web site:
"Automobile and vehicle catalyst manufacturers have argued that gasoline sulfur affects the performance of vehicle catalysts and causes increased exhaust emissions. Based on test programs, which demonstrated the deleterious effects of sulfur on vehicle emissions control systems, EPA issued regulations limiting the sulfur content of gasoline. These regulations allow a phase-in of lower sulfur gasoline nationwide. Beginning in 2004, refiners must produce gasoline which averages 120 ppm sulfur with a batch limit of 300 ppm. In 2005, gasoline sulfur levels must average 90 ppm with a cap of 300 ppm; in 2006 these limits are 30 ppm average and 80 ppm cap.
Refiners are evaluating technology that will allow them to manufacture all of their gasoline with lower sulfur levels. There are several approaches to manufacturing a low sulfur gasoline, such as hydrotreating the feed to a catalytic cracker or desulfurizing the heavy cut of the catalytic gasoline.
Sunoco has been producing lower sulfur gasolines for years relative to the national average of 339 ppm. Tables 3 and 4 include information about Sunoco Ultra
