I have had redline fluids in my cars since early 90’s. Newly I switched to royal purple, simple because the nearest redline dealer is a 50 mile round trip, while RP is at nearest NAPA.

I had transmission rebuilt by a dealer after 50k miles caused by grinding sound when changing into fifth. I had factory gear oil, changed to Royal purple at 30K miles when I start experiencing early warning signs of tranny issues. My last experience was that by put a better lubricant in, I was able to deal with early issues. Well royal Purple did not help and dealer after being a DEALER replaced the tranny. Well fast forward 67k miles. I just start experiencing early signs of grinding in fifth. Since Redline Line was in an same car for over 100k miles previous car, clearly the liquid has been changed at the proper intervals and not an issue with same transmission.

So got couple bottles price was three dollars less than somewhat local, no tax and no driving for 2+ hours in traffic to get two bottles.

The shift points became a tad more pronounce nearly notchy, but still smooth and NO GRINDING! So for my little Korean car the redline is a miracle liquid :

PS Not bad mouthing Royal purple, I just flushed rear end and transmission in other car. But seemingly Redline was/is/will be my best choice :
