International Motor Sports Association's (IMSA) president Scott Atherton confirmed the race was part of the schedule for the 2018 IMSA SportsCar Championship (IMSA SCC) in August 2017.[1] It was the fifth consecutive year the event was held as part of the WeatherTech SportsCar Championship. The 2018 Oak Tree Grand Prix was the tenth of twelve scheduled sports car races of 2018 by IMSA, and was the seventh round not held on the held as part of the North American Endurance Cup.[2] The race was held at the ten-turn 3.270 mi (5.263 km) Virginia International Raceway on August 19, 2018.[1] As in previous years, the event was also the second GT-only round of the IMSA SportsCar Championship season, in which only the GTLM and GTD classes were scheduled to compete.[2]

After the Continental Tire Road Race Showcase 2 weeks earlier, Ryan Briscoe and Richard Westbrook led the GTLM Drivers' Championship with 241 points, ahead Antonio García and Jan Magnussen with 237 points, and Joey Hand and Dirk Müller with 232 points.[3] With 250 points, the GTD Drivers' Championship was led by Bryan Sellers and Madison Snow with an eighteen-point advantage over Katherine Legge with 232 points.[3] Ford and Lamborghini were leading their respective Manufacturers' Championships, while Ford Chip Ganassi Racing and Paul Miller Racing each led their own Teams' Championships.[3]

On August 13, 2018, IMSA issued the latest technical bulletin outlining Balance of Performance for the event.[4] In GTD, the Ferrari 488 GT3 received a reduction in turbo boost and a fuel capacity reduction of 2 liters. No changes were made in GTLM.
