They didn't need any help, the problem was the sulfur (sulpher) in diesel fuel prevented them from meeting emission regulations for cars.
ULSF (ultra low sulfur fuel) wasn't available in the US until 2007, and not completely fazed in until 2010. There was something like a 2 or 3 year gap between when the emission standards went into effect, and the availability of ULSF.
