Well dayum....you owe me $20

It will be intresting when I get my VOA of the exact same stuff from Blackstone at least.....looks good though....stout stuff to say the least....

Ag = 9ppm!?!?!?!?

Al=14?

So much for "racing oils" being low on Ca additives.

So much for honesty.

 

[Hirev]

What is up with all the extra debris?

 

[Winston]

That is a lot of Boron AND Moly AND Magnesium.

 

[buster]

That is one heavily loaded add pack. Looks like a tough oil.

Wow. Any more metals in this oil, you could lift it with a magnet.
But seriously, looks interesting.
Has anyone ordered a TBN on it?

Got your results from Blackstone yet?

Guys, other than the Al, what's the big deal?

 

[Pablo]

Ag = 9???

 

[bruce381]

basic PCMO package with a percent of boron ester and MDTC should run well with low wear BUT still to high in price for me.

Hey Pablo, do you ever have anything good to say about any other brand of oil?
