Hey guys.

These oils are regarded very highly by 2nd gen GS4 owners in this thread, with some saying they've gotten an increase in horse power (1-4 HP).

I was wondering if any of 1st gen GS owners with 100K + miles on the odometer have tried Redline or Amsoil synthetic fluid for either rear differential or transmission stock fluid replacement. If anyone has experience with this matter please post some feedback.

Thanks in advance.

I replaced the differential fluid about 6 months ago. I do not remember the name of the brand, but I replaced it with full synthetic 10w-30 motor oil. I only had the car for 4 months before I changed the oil, I have not noticed any difference that I can attribute to this oil change because I have been making various performance improvements over the months. I did it because lower viscosity oil usually will make some kind of hp difference. I will soon replace the automatic transmission fluid with full synthetic fluid.
