I'd like to add to this post. I have a 331 9.5.1 and I'm using 5w50 syn. I used 10w30 conventional for the first 500miles after buildup. Now ever since buildup I loss about 1/2 quart of oil after about 2 weeks of hard driven. (I drive like a nut) My plugs look great all 8 of them look the same, good burn. I have no leaks anywhere. Where is this oil going? Does syn oil burn different? Should I try a different wieght of oil?
