Red Line Synthetic Oil Corp. has announced the continuation of its NASCAR Nationwide primary sponsorship of MacDonald Motorsports and driver Michael McDowell for this weekend's upcoming Camping World 300 event at Fontana, California's Auto Club Speedway.

In addition to Fontana, Red Line Oil will also support the team at the upcoming Dollar General 300 at Charlotte Motor Speedway and the O'Reilly Auto Parts Challenge at Texas Motor Speedway.

Director of Sales and Marketing for Red Line Oil, Cameron Evans, said: "The car looks great, the team works hard, and our customers and fans all responded in a big way to our sponsorship.

"We like this programme since they were customers of our products long before we ever worked together at this level."
