Nascar Testing Unleaded Fuel

From Fox Sports:

AVONDALE, Ariz. (AP) - NASCAR is hoping to speed up its switch to unleaded fuel by testing it at selected Busch and Craftsman Truck series races later this season.

The racing series has used high-octane leaded fuel for decades, but has been searching for an alternative for years and believes it may be close to a final product with supplier Sunoco. They hope to have it in use at several events this year, well in advance of their plans to switch to it exclusively by 2008.

"We think we have something with Sunoco, and we need to start testing it and see if it's right for us and if it works well with our cars," said Robin Pemberton, NASCAR's vice president of competition.
