I run Mobile 1 Extended full synthetic 10w30 in my 2012 5.7 Hemi. The manual calls for 5w20. But I figured since its hot here, I'd go a little heavier. Is this gonna ruin something? What say ye? Is this safe?

he's got longer than that, look at the manual. . I ran 7500 miles on my first oil change and took it to the dealer. They asked if it was the first and I said yes. They bout fell out and said it's gotta be done at 3k. I said check the manual fellas it says 8k. I do mine now a days at ~4k but I'm on about 6500 right now and need to get in. Bad thing is the oil still looks fresh at 4k so I don't usually worry if I'm a little behind on it.

Other than that just change on regular basis.
We suggest at my shop 3 to 5 on standard oil, 7 to 10 on full synthetic. On gasoline engines.
5 to 7 and 15 to 25 respectively on diesel.
My amsoil customers avg about out at about 17k for diesels
