Duragard Diamond Plate Synthetic Blend CK4 10w30 Engine Oil - 2.5 Gallon Jug - Meets Ford WSS-M2C171-F1

I used this oil for a classic car since it has good zinc/phosphorus levels and has a gasoline rating. Comes in 10w30 and 15w40. So far the car really likes it. Runs real quit and smooth. Oil seems real tacky and likes to stick on surfaces.
