A lot of what we did here was develop strategies based on science and then test them. Before you test it 10w30 looks like an incredible oil, great additive package and base oils like other redline but zero vii's per Dave. So you can see why the theory was it is every bit as good as 5w30 and even better, but then we tested it. It was the only redline I tried to date that had a slight tick the entire interval. It was like 10% of a tick compared to when I first got hemi tick, which is why I ran it for an entire interval, but no bueno. Now, if you don't have hemi tick or 10w30 happens to keep tick away, then there is a lot of benefits to running that oil in warm areas as there is no vii's which is desirable. Didnt work for me, but that doesnt mean it wont work for others. Most of the guys testing all of the different redlines were in cold states, so I believe I might have been the only one to try it, tbh I forget that part. I wanna say Ronnie ran it as well, rlk, but he didnt have hemi tick. I know he was really loyal to one specific redline, he is a helicopter mechanic so this oil really impressed him. His uoa's must be in blackstone thread, maybe that was 10w30, he was in warm state as well.
