Hey guys,
As I am now due for my first oil change since I bought my rig, it has got me thinking and searching around the boards for what oils everybody is using.
My rig currently has Maxlife in it which I am going to stick with, however the weight is 10w40 and I have now read in multiple spots how 10w40 is not recommended and could easily gunk up the motor and components based off of them having to mix oils and add things to reach the 40 level. I know that 10w30 is recommended, but I am curious if it is the best choice in the hot temps of Texas, especially when under the rigors of offroading in Texas heat.

Out of my own curiousity, What are your guys' opinions on the subject? <img src="/forums/images/graemlins/kewl.gif" alt="" />
