WSRD has a long standing relationship with Schaeffer's Engine Oils dating all the way back to our 1000+ horsepower drag racing days in the Mitsubishi scene. Schaeffer's Engine Oil has been the most dependable engine oil tested in our engine program for all power levels. WSRD utilizes the 5W50 engine oil in all of their stock injector to E85 powered tuning packages, and the 20W50 engine oil in all of their methanol, fire breathing drag builds!
