The purpose of this post is to ask the oil experts of the internets if you have ever come across and how you think this may have happened. I found this interesting and would like to talk about how this may have happened.
I wont be mentioning the brand of oil so as not to call out the manufacturer. They have been very attentive if a little vague. Their advice was to return the product to the distributer in the expectation it makes it back to them for analysis. Not going to happen as Amazon does not want the oil back. I have 8 bottles left if you want to risk it!
So the story is, I bought a case of Semi Syth 75-90 gear oil from Amazon. Went to change it out and noticed the first bottle going down was very slow flowing. I didnt think much of it as it is gear oil after all. I was using a funnel attached to a clear plastic tube that was going into the tranny dipstick. I picked this up at the auto parts store and it had a mesh screen at the bottom of the funnel. The second bottle stopped flowing about half way. It sat for 30 mins without flowing at all. Nothing seemed out of place so I decided to use another funnel, emptied the contents of the first into an empty container and found that the screen at the bottom of the funnel had clogged up with what looked and felt like petroleum jelly. Below is a link to a Picture.
The manufacturer did not provide any technical explaination on how it may have happened except that it may not have been stored properly or that a seal on a bottle may have been broken. (This happens to oil?)
The bottles in the case all had matching date codes and the manufacturer did not express that they thought these were counterfeit. They looked at the date code and batch number. The manufactured date was September of 2018.
