Oil

[TomK]

I have a 2103 Big Horn with 5.7 hemi. 1st time truck owner. I see it calls for conventional oil. And I believe they put conventional in at my last oil change as it only cost $48 or so. It's got 152K on it now. Is it safe and is it beneficial for me to switch to high mileage synthetic oil or stay with conventional oil??

See "Synthetic Oil" thread...tons of good research done there.

I use Mobil 1 Extended Performance full synthetic in mine and have no issues ... It's obviously more expensive than conventional but a bit more now as opposed to a big time repair bill is easier to take ... I'm on my third RAM (2013 - 2017 - 2020) and used synthetic in all of them ... It boils down to a personal choice, and with synthetic you can go a little longer between changes ..

The main benefit is tbn retention, meaning synthetic oil can safely operate longer as it starts with a higher tbn. PYB makes a real good conventional oil if you go that way.
