Interesting Oil Filter Discovery----- 07's take a different filter.....

[Trinity]

Had similiar experience last week. 06 in the book for the Mobil 1 was one number, but by chance, I asked the guy when checking out to double check the part for the 07. Yep, M1-113 is the new one for the 07.

I just wish Walmart would carry the M1 filter. Now I have to go to Walmart to get the Mobil 1 oil (5 quart bottle + 1 single; it's cheaper and I like the 5 quart bottle - makes it easier to recycle the old), and then Autozone to get the Mobil Filter.

I didn't post my find because I have been on the road most of the week and not at my home computer. Thanks for posting - we will save some others some grief.

This does not have anything to do with an engine change.

For some reason GM changed the threads from 13/16" on pre2007 vehicles to 22mmX1.5 on 2007's. It is not just the H2's. The 2007 Silverado Classic which is the same truck as the 2006 Silverado uses a different filter for example. The 2007 Corvette uses different filter than the 2006 Corvette and so on.

I do know that the AMSOIL EaO47 fits on the 2007's and you cannot find a better filter. http://www.amsoil.com/StoreFront/eao.aspx?zo=1132530
