Lucas Oil Speedway's tentative 2018 schedule was announced on Friday.

"We're excited about what's in store for our fans and drivers in 2018 with a schedule that again has variety," Lucas Oil Speedway General Manager Dan Robinson said. "The foundation is our 13 Weekly Racing Series schedule, but we also tried to space out our specials throughout the schedule."

Robinson also said there will be purse increases for the featured classes each week during the Weekly Racing Series in 2018. USRA Modifieds will take home $1,000 for feature wins when they are featured and Out-Pace USRA B-Mods increasing to $750 on nights they are featured.

Engines will fire up for the first time on March 31 with an open test and tune. The season gets going on April 7 with the Weekly Championship Series Spring Opener as the ULMA Late Models, USRA Modifieds, Street Stocks and Out-Pace USRA B-Mods hold the first of 13 weekly points programs.

The first special of the season is set for April 13-14 with the 5th annual MLRA Spring Nationals Presented by RacingJunk.com. USRA Modifieds and Street Stocks will join in the action.

The month of May wraps up with the 26th annual Lucas Oil Show-Me 100 Presented by ProtectTheHarvest.com, May 24-26. The crown jewel Late Model event is co-sanctioned by the Lucas Oil Late Model Dirt Series and the Lucas Oil MLRA. USRA Modifieds also are on the schedule.

Stars of the Lucas Oil Late Model Dirt Series and Lucas Oil MLRA return to the oval track on July 14 for the 12th annual CMH Diamond Nationals. USRA Modifieds also are on the schedule for a full program.

August fires up with national-touring Modifieds taking the spotlight, with the USMTS Slick Mist Show-Me Shootout presented by Foley Equipment on Aug. 4.

"The 2017 season was outstanding, with tremendous competition and great fan support," Robinson said, noting a record 113,000 fans who came through the gates. "But now we're focused on making 2018 event better, with the revealing of the tentative schedule the first step."

Season passes, along with Show-Me 100 three-day passes, will go on sale later this winter. Look for that information at LucasOilSpeedway.com and on Lucas Oil Speedway's Facebook page.
