I live in Southern Calif and my Z28 is new..............I am constantly hearing the battle of 5w30 vs 10w30.....which is better?
What are pros and cons of each?
I can probably easily use either, but which is better for performance and which is better for protection,etc.
Thanks for the advice in advance! ![[stretch]](/forums/graemlins/gr_stretch.gif)
