Not a 3 year break in, or longer for some folks. I’m not saying slap it in and send it to the moon, but a more realistic approach is what I’ll be doing. 12k miles is just insanity imo, and I’d like to see the evidence that’s 5-10k miles isn’t good enough?(not specifically asking you, but the general public). I’d be more willing to bet that people are getting whines from them by dumping the oem fluid out and putting in garbage fluid right off the bat.
