Voted a long time ago for whatever Dino juice was for sale at the dealership. Now running Mobil 1 with a Mobil 1 filter since it was 1/2 off. Next year we'll see.

My neighbor uses Royal Purple Full Synthetic in his Hemi and my friend says to use nothing but Amsoil. I'm torn between these 2 for my next oil change.

Mobil 1 and wix or fram premium filter

Whichever is cheaper lol. As long as it's full syn there won't be a difference you can feel or see. RP will probably be the cheaper option every time but it still aint cheap. I'm running RP right now and even on sale it cost me 75 bucks for the 7 qts plus a K&N filter. Where as with Mobil 1 with a Wix filter cost me about half that and the truck feels exactly the same. No power or mpg gain (even though I wasn't expecting one). Just run any syn and you'll be fine. Don't get caught up in the brand wars like I did. As long as you take care of the truck it will take care of you.

I still run good old dino oil, no synthetics in my truck. I take it to the dealership for oil changes as I get a 4 pack of oil changes for $65 or so and they fill it up with 7 qts and no charging me extra due to it being a Hemi.

Makes life easier when I spend $65 for four changes instead of one.

Why does my oil temp go up when i first start to drive. For about ten minutes. The drops down.on my 2007 dodge ram 1500

Mobil 1 Full Synthetic with Mopar filter. I even started sending my oil to Blackstone for oil sampling and everything looks great for 118,xxx miles on it.

Lxman, where do you get Mopar oil from? Or does anybody know?

I use Mobil One with a Mopar Oil Filter, best price is Walmart 5 quart. The Interval is minimum 6,000 miles up to 7,500 miles between changes. Highway driving everyday for 48miles round trip. Mfg. recommends 7500mile intervals, but I swear I use a quart in 6,000 miles. How about you?
Hemi's forever ole !

Napa premium 5w30 synthetic with a napa filter. just bought it used with 153k, I will probably go 3 or 4 k.
