How much ink does an HP 950BXL OEM really contain ?

[smikey]

I have an HP Officejet Pro 8100 that uses 950, 951 ink cartridge. Recently i bought a new 950bxl to replace my empty starter black, I know that hp is putting in 53 ml of ink for this cartridge model so i weighed my 950bxl and got 130 grams, weighed my empty 950 starter black and got 49.5 grams. Subtracting 130 with 49.5 i have 80.5 grams or ml of ink. My question is why does HP posted 53 ml of ink on their website while the actual volume is 80 ml?

The actual ink volume is 80ml.

Yes, the actual ink volume is 80 ml for 950bxl, and the actual ink volume for the 951xl colors is 25 ml compared to the declared volume of 17 ml by the OEM.

951XL's hold 25ml
950std. holds 48ml
951std. holds 13ml
