I use Joe Gibbs Hot Rod full syn. 10-30 winter and blend 2 qt. 10- 50 summer. Broke engine in with Joe Gibbs BR 30 brake in oil went to Hot Rod oil after 300 miles. Use Mobil 1 filter. Pulled pan after 40 passes, pulled a rod cap and a main cap and had 0 wear. Engine saw 7400 RPM and makes about 1300 Flywheel HP, twin 70 mm turbos 16lb boost. Ran 8.98 best et and 161 MPH best. Change it about every 3rd race in summer. And once in winter. Also run vacume pump that helps keep trash out.
