Hmm, a starting TBN close to 9 compared to the 12.5 listed on their website. A formulation change?

EDIT: Didn’t notice the test method in this VOA. Thanks @Pablo

Thanks, I completely missed the method. Carry on! I was actually thinking of going back to Amsoil’s SS line, but the membership Pablo!

Just kidding, the price adding the $10 6-month isn’t terrible when it pays for itself right away if going for free shipping; which I wish were offered at a lower price point but I get shipping is crazy these days.
 
This VOA additives list is really good. Plus, only inches short of a 5w30 @100cst.
Who did this Analysis? Sure easy to read.
One of the thicker 20 grade oils. I almost went for this oil in my 07 Fit, but I’m going straight to their AZO 0w30 to curb consumption a little and hopefully slow a rear main seal leak. I’m sure the ester content will help there, but I’m not sure how much my fuel economy will suffer. If the rest gets better, I’ll live with it.
