New to me LS460, 6 weeks and 6k miles (125k total) while in my stable.
Added RP water wetter 2 weeks ago and now my heat blows hot about half the time. No measurable change in engine temps. Removed coolant to add RP WW without overflowing, coolant level has remained constant and at max level since addition.
What in the world is happening here...
Updated: Redline, not RP.
