Yes thank you, I see now it says "GC". I missed that in the picture. That's odd.ASTM D7593 for fuel dilution
ASTM 2896 v 4739Hmm, a starting TBN close to 9 compared to the 12.5 listed on their website. A formulation change?
Sure, I would. Amsoil SS is a good product.Would you run it 10000 miles in a 2019 Crosstrek?
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.This VOA additives list is really good. Plus, only inches short of a 5w30 @100cst.
Who did this Analysis? Sure easy to read.
