Ryan T. Fetter –
Seems to be the same product, I would buy from my John Deere dealer, at a better price, and without traveling 30 miles to pick it up. Used it in my John Deere mini excavator 27D.
George –
I ordered this oil on Tuesday evening and given a delivery day of Wednesday a week later, Saturday, four days later the oil was delivered on my door step by FedEx. I live in Georgia, how do they do that? Everyone knows that you have to punch a small air hole in the lid before pouring the oil to assist in free flow, not this container, it has a special snap on cap for this purpose, now you can pour and seal this lid and air vent. Wonderful. This oil States that it is for Hitachi excavator, Zink Free and stabilized for 10,000 hours. You’ll have a hard time finding that information on any other oil you buy. I’ll buy this oil from now on.
