No mention of the unicorn tears on the label here, just a proprietary additive package.
Possibly the same add package as Valvoline synthetic.

Maybe this version uses crocodile tears instead.
How can you say that with any certainty.
A used oil analysis isn't the be all to end all and it cannot see organic additives,so just because it looks similar to valvoline in no way means it is.
Synerlec is great stuff and I've personally seen track and street pounded engines where the cams looked new,not even a wear scar and that includes countless cold starts with immediate runs.
I've used and like the stuff with synerlec and have some of the older euro blend(with synerlec) in my stash.
Now for a daily driver I don't feel the cost is worth it simply because top shelf syn's from the majors cost less and I don't feel a commonly driven motor requires the overkill. I feel the same about red line lubricant. Absolutely great stuff just not cost effective in a daily driver.
Royal purple makes great products however when compared to less costly alternatives I just can't justify the extra expense in a daily driver.
Race engine,heavy duty working engines,stationary air cooled engines then yes a higher quality speacialy oil would be on my radar however in a modern engine there are less costly alternatives that provide more than enough protection for the engine and lets get serious here. Today's engines last longer than the car it's installed in and when was the last time you saw a vehicle heading to the wrecker because of engine failure.
However if you like the hps stuff lets us know how you like it.
