JOLIET, Ill. -- Diet Mountain Dew will be on Dale Earnhardt Jr.'s Sprint Cup car for fewer races in 2013, but NASCAR's most popular driver is having no problem luring new sponsors.
"We have more demand than we have supply pretty much,'' Earnhardt said Friday at Chicagoland Speedway. "We have got the majority of the season with the (National) Guard and then Diet Mountain Dew is going to back off a little bit, and that makes it a bit of a challenge to fill that small of a gap.
"If it were a bit larger gap, it would be easier to fill."
National Guard previously announced it would be on the No. 88 Hendrick Motorsports Chevrolet for 20 races in 2013. Diet Mountain Dew was contracted for 16 races this season with PepsiCo having the sponsorship rights for 20 races. Earnhardt did not say by how many that number would shrink.
But Earnhardt made it clear sponsorship is not an issue as it has been for other teams.
"Every sponsor on the car wants to be the top guy," he said. "It's a bit hard to have a top guy when you are trying to work with multiple sponsors. It's just a little bit of a balancing act.
"Hendrick and all their people there are just taking their time sorting it out. We've got a lot of irons in the fire and some real good potential stuff going. We just got to kind of decide which one is going to work out, which one we want to work with."
