I purchased a 2013 FR-s in October of 2017 with 16,000 miles to do SCCA Autocross (SSC) and a couple of track days. With the way I abuse cars I change all the fluids yearly and the engine oil about every 3,000 miles, which I know is way to early for synthetics, but I do it anyway. Last spring I changed the tranny and diff to Redline noticing quite the crunch threw 1st, 2nd, and 3rd in the cold until it would warm up. I live in the midwest so we did get some negative degree weather. This past Saturday I changed out to Motul 300 for both tranny and diff again (now 24,000 miles on the car) and there is much less crunch and feels great when warm. I will say that we have not had any real cold since Saturday so I can't truly compare but in the low 40's the Motul definitely crunches less than the Redline. For this car I will not be going back to Redline fluids even though I ran it for 20 years in a Honda CRX MT but that is a different beast and was an Autocross trailer queen.

Hope this helps.
