I'm on another cross country road trip to California. Thankfully I got a friend to pick some up from the local dealer before he flew here today. It was only about half a quart low, and I have 3 quarts now.
It was a relief when I finally found out what it was. I had to sleep on it before I thought of the SLS.
I will post some more photos in OD. I plan to replicate some of photos I took of Ol' Turbo last year. I hit the road from Vail to Vegas, then stop in San Diego and LA before returning home.
