Here's a question for the guys using redline, which I was once a user. If negatives are it costs a lot more, it leaks a lot more (and out of places it did not use to), then what are the positives? I did not find the shifting to be any smoother/easyer/quieter (which I thought it would be, wanted it to be, but was not. I was even willing to tolerate a bigger oil spot for better tranny performance/protection), than regular non detergent oil, Castrol GTX 20-50. When I changed both oils, Redline/Castrol, neither one showed any more metal particles than the other, so it seems they were both lubricating the gears the same. The shifting was smooth with both, overdrive engaged and disengaged the same with both. What am I missing? Both shifted the same, both protected the gears the same, but Redline costs a small fortune and it leaks a lot more, increasing the small fortune that Redline will make from me. (Maybe this product works better in modern cars that are suppose to use synthetic?)
I take really good care of my car appearance wise and running condition. I stay on top of all mechanical issues and change all the oils regligously. If there is a better product for my car, I want to use it. But found no improvement with Redline. It may sound good on paper, but when I used it, I found no difference. What would be different with my tranny/overdrive than other Healeys' where others say they do. Sometimes I think the way products are written up provide a placebo effect when we use them.
