I'm using it in my Jeep right now. It is rebranded Valvoline Synpower with a slightly weaker add pack. IMO it's great stuff but then again I've been a Valvoline man since I came out of the womb.
I'm running it right now in the 3.8 n/a engine in my Buick. The stuff looks almost clear on the dipstick (of course it only has 220 miles on it right now!).
My plan is to run 7 months, ~6300 miles, until next April, but if I do any road trip stuff over Christmas, I might hit 7000.

Love the stuff! Been using it for a while. Good Valvoline Synthetic oil. Use with confidence. The price is right!
