Amsoil only please. Although I appreciate responses, I don't use anything other than Amsoil in my '07, so that is what I am looking for in responses.

Here is my reasoning for asking. Back in 2008, right at my second oil change, I swapped over to Amsoil. I have been running it in other vehicles for a LONG time, so I like the stuff. Well, I went with the recommended 5W-20 and for some reason, my gas mileage went to hell right away. I called them and they told me to try 0W-20, so I did and my mileage came back up to what it was before + a slight improvement if I wasn't getting on it.

Fast forward to this weekend. I've been using 0W-20. Got a buddy that told me he wouldn't recommend that, especially with a MDS engine (Engine Code 2). He said Amsoil doesn't recommend using anything other than 5W-20 in that engine and I told him he was wrong. Well.... I was wrong. I just checked the website. Amsoil has removed the 0W-20 recommendation as the primary oil, and now the site only lists 5W-20.

Just wondering what others who use Amsoil are running in theirs.

All the best,
Glenn
