I’ve got a bottle of redline 75w90 for next years transfer and rear diff fluid swap. After that I’ll probably try hpl. I wouldn’t worry about using anything they hpl makes, no matter the product. But, if it ain’t broke in your case. I switched my wife’s 24 over to redline oil and noticed a few things that make me like it enough to probably use it from here on out. I keep waiting for redline cvt fluid to become a deal since it’s amber in color, I’d like to try hpl cvt fluid, but it’s red if memory serves and I’m under warranty.I've been reluctant to try anything other than Redline MT-LV in the transmission since I've had such excellent results with it over the past 15 years. I'm very intrigued by the HPL though and for the transfer case and rear diff I'm very interested.
