The dealership's service writer was stupid. The sulfur content is strictly controlled by EPA regs. What ever the real cause of the problem, it wasn't sulfur.
Cheap gasoline probably does not have the same level of detergents as the best gas. They all have the minimum required by the EPA, but is that really enough in the long term??? The Top Tier brands have more detergents for competitive reasons, or use the real cheapo stuff plus an effective additive like FP-Plus.
Check your car with at least three tankfuls of each gas on repeatable drives to find the lowest fuel cost per mile, not just the lowest cost per gallon, as well as the fuel your engine runs best on. Here on the west coast, BP's ARCO brand is the worse we get, and even though the cost is lower than most others, the gas mileage is noticeably worse than any other in my cars.
