[Linked Image] The additives in the oil sample is different to what Valvoline says they should be. Per the spec sheet, Zn/P should be 1120/1000 ppm, and Calcium/Sodium 1880/520 ppm.

For a car? I don't see why not, although an HDEO would likely be just as good, for a little less money.

That's true, I have an older spec sheet that lists the sodium and calcium.

I use the 20-50 in my Harley 103 and it runs quieter and smoother than Mobil 1. I use Mobil 1 in most everything but I like this oil in the Harley.

There are many possible molecule types that the boron is part of and unfortunately there is no way of knowing from a VOA / UOA. With 291 PPM of it, it sure is a prominent part of the additive package.

As you know I use Mystik JT8 semi syn 15/50 and I have so much of it I dont know if I will ever get a chance but if I do, the Valvoline Syn is a "I want to try oil" even though its not diesel rated for my bike, it sure looks darn close to a Diesel oil. Always been a fan of Conventional Valvoline MC oil in past bikes, honestly and truly, never ran one bike with a full syn and would be curious ... I doubt I will ever get to that anytime soon I still have 1 or 2 years supply of the Mystik oil left

My bet is AW/ EP for the transmission. For what it's worth, you're right, I don't know. I wish I knew
