I’ve got big shoulders! Let ‘er rip. I won’t cry I promise! 😢

ROFLMAO!!!!


Yeah, well, you and I talk about this stuff damned near every day. So I'm not posting anything here that you and I haven't discussed at length.



But you brought up a great point, and when I was talking to Lake recently, he absolutely went off on the oil and additives issue.


Also, I saw a video that David Vizard did on the subject. Now, he was also selling Oil Extreme, a calcium carbonate based additive. But he had some pictures of failures induced by excess ZDDP. Does Oil Extreme work? I don't know.



People are buying oils, good oils, like the Brad Penn, and then dumping 1-3 different additive with ZDDP into it. And then wondering why they have failures.


You also brought up a great point about rollers vs. flat tappet. Few people understand that in certain areas, flat tappets actually out accelerate roller lifters. And even fewer understand what that does to performance.
