What Oil to use?M1, Castro synt? or other

[vath2001]

FYI... I Just did a Mobil 1 oil change, 10w30. In retrospec, I would have gone to 10w40. I am not sure but it seems to runs a little hotter now, compared to the old oil (which I have no way of knowing the weight). But now I am driving in the summer compared to the spring.

I bought my oil from Meijers at $19.99 a gal (on sale), and the quart cost me $5.49, I got the filter from the Zone. I would recommend getting the filter wrench from the Zone at the same time.

My thoughts on oil... I run the the TL and Chevy on whatever is on sale (they have 135k and 100k respectively). I ran my old Civic SI on whatever was on sale... when I traded that away it had 190k. You could argue that running better oil makes the engine last longer... or I would argue that doing oil changes at the prescribed interval it more important than the label on the bottle. But what do I know.. I can show only 425k of research.
