Doesn't make sense, does it?
I'd like to know more, I think he just left young engine stuff, so for now that would be a guess. We have many examples from beginning of the thread that hemi tick engines wear goes down with the redline, but I doubt redline is the lowest wear oil in a correctly running engine, we see that at Bob's. Personally, I'd go with the oil that left by engine butter smooth even if wear was slightly higher. Now, if we are talking 20ppm higher, no way I'd take a little noise. Ramfini is in a perfect spot now, I think we can lay down judgements on different oils based on his uoa's from here on out. So looking forward to seeing those.
What is it about redline that causes slightly higher wear, that is loaded question yes? Esters or high moly, moly too high? Even pao, or boron? I think the simplest answer is zddp, we know that increases wear and discourages wear and is the most disappointing thing about redline's formula. I say that only because in the case of hemi tick I think it is all those other features that stop the tick and not the zddp, we tested zddp a lot in early years and had near zero success against tick with it, so perhaps that 1200 is not needed for our purposes. However, with the api just going as low as possible with zinc in new specs, it doesnt bother me that much to have the extra protection. But that is my guess to the wear a tad higher, zinc related wear.
As always judge something on the body of work and not just one uoa, if I remember correctly rlk's uoa's had wear dropping in every uoa in a perfect running hemi. Of course he never did run anything but redline, but he produced some of the best uoa's on the board. I think guys should just try and couples things and see what sticks.
