at 14000 miles they added 5 1/2 qts of mobil 1,the viscosity had thickened but not as badly as amsoil,they did a filter chnage which lowered wear metals,but they still where higher then amsoil.

So what I gather from the test is that mobil 1 was getting used up/burned more then amsoil. Mobil 1 needed a filter change to keep wear metals in check but was still higher at 14K miles compared to amsoil. And mobil 1 kept its viscosity in check better then amsoil.



did you see this part.....

To Amsoil's credit, wear metals remain in check, but we will soon see whether that was really thanks to the oil or just to engine break-in. We'll start posting detailed analysis in the coming weeks.

The one thing that the testers said multiple times was how accurate was the test? Mobil 1 was tested on a new motor in the summer. Amsoil was tested on that same motor after the fact in colder weather. I myself would like to see the follow up test with mobil 1 again.



if you reexamine the dates of the samples you will find that both oils were tested for approximately one year. you will also find they are retesting mobil 1.

Next up: is it true that Mobil 1 was handicapped by an engine still breaking in? We find out!
