My polo is a 1.9 tdi - 9n3, i have the problem of oil consumption (about every 7-8000 km i do a topping of nearly half a kilo).
So I decided to buy on Ebay, 4-5 Lt. of Castrol SLX professional powerflow - longlife III, but in the ads it seems that this oil exist into two different containers ...

I attached a photo:

Do you think that difference? Which should I take? The specifications are identical ...
Thank you in advance!

Bye
