PP seems to have been as good as it gets among shelf oils since its release.
Syntec is okay, but nothing special, except for GC.
Do you have some specific reason for writing that Synpower has only recently been a good oil, or are you basing this on the historical trend of the industry?
I'm not calling you out, I'm just wondering.
I used my first Valvoline syn, VR1 (Synpower dyed blue) last summer, and am using my first run of Synpower at the moment.
It will come out next weekend and be replaced with another run of Synpower, which I intend to UOA.
I had always wanted to try Valvoline synthetic, but the price had never made sense.
With FAR VR1 and closeout plus MIR pricing on Synpower, I decided to give Valvoline syn a try.
We'll see how the UOA looks, especially shearing and TBN.
