Cars: Billy Oilchanger (Octane Gain)

From Disney·Pixar Cars, here is the Mattel 1:55 scale diecast of Billy Oilchanger, better known by his sponsor Octane Gain (No. 58). This character has been released a couple of times over the years, but this particular single pack release is from the 2012 Toy R Us exclusive "Radiator Springs Classic" series.

As shown in the screenshot above, Octane Gain is briefly seen in the film's opening Motor Speedway of the South race. He is one of the 36 race cars competing for the Piston Cup.

While Octane Gain isn't available in stores currently as part of this year's line up, you can find him easily online at either Amazon below or eBay HERE. Have fun on the hunt if you're still looking to add this one to your Cars collection!
