Hey all looking for advice on oil in a 99 Cobra Mustang. 4.6 4valve motor. just about 10k since rebuild with probe forged pistons and the addition of a paxton novi1000 supercharger. car has stand alone fuel system 42lb injectors etc. also adding methonol injection at this time. my thought was mobil 1 5w30 but seemed like the easy way out. also has 7 qt sump. thanks will be running 10-12lbs of boost
