Thanks for sharing. I was curious did you send a sample prior which is why they say there is nothing wrong and do they compare each subsequent results ? I was curious how much is it for an oil analysis ? I'm not surprised that Amazon oil is as good as it is. If you think about it, Amazon is a huge market and any supplier that gets this contract automatically has a big supplier to sell their product. If anything amazon has a reputation to maintain, so if there were issues with amazon oil, the company would do something immediately.Thanks for replying, @Design, I will send three oil analysis kits in the coming months. One will be my final UOA of the Mobil 1 0W-20 Extended Performance, one will be fresh out the bottle Amazon Synthetic 0W-20 oil (why not?), and the last one will be whenever I need to send in the Amazon Synthetic oil to get tested.
A quick note on the Mobil 1 Extended Performance currently in my vehicle, I can't remember if I mentioned it before. The oil itself was from the bottle on the previous oil change in the vehicle, about 7 months opened. I am not sure if this will have any impact on my analysis, but I will definitely make a comment about it when I send out the oil.
Does not surprise me that the quality is as good as others. I'd use it on my car, the bigger issue is sticking to oil change intervals vs. oil brand name imo.
