I'm guessing that this would have come with a Valvoline product; motor oil, antifreeze, etc. The text would indicate that this was released around 1998 (or at least after the 1997 season).
"Motorsports Collection" made various premium releases around that time:
1997 NAPA
1998 John Deere
Both of the above sets were weekly store giveaways.
I'll poke around and see if I can find any references to a Valvoline set.
