Coming up on first Oil change on 2011 RAM with 18k bought in January, anyone else use mobil 1 extended (gold bottle) oil 5/20 ? what kind of miles are you going between changes, Im thinking every 8k on this? what about you guys? Thanks!
7500 mile oci is what the manual states on dino oil, so you should be good. that being said, some have posted m1 makes for a noisy engine, "hemi tick", i have been using penzoil ultra 5-20, and so far no hemi tick. valvoline syn is also known on the forum to quite the engine down.
I use Mobil 1 synthetic in my '12 and have used it for many years in every vehicle I've owned...street, off road, garden tractor, etc. I haven't had any unusual ticking or such as mentioned occasionally here with my Ram. I wonder if our locations and climate differences have any impact? Regardless, I've not had any issues running Mobil 1 for years and years. Now, I'm not one to say that Mobil 1 is the only oil one should run...not by a long shot. There are quite a few oils out there worthy of a good, quality stamp of approval.
I've used mobil 1 extended performance for the past several years in our vehicles, recently switched to amsoil as I get it cheaper now. It's a good oil, depending on application it will last up to 15k miles. In my ram it looked good until about 7,500 and I changed it shortly after that. In our 4 cyl car it looked good at 12k miles and I changed it shortly after that. Make sure to use a good (extended life) filter, like the mobil 1 ext perf filter.
Oil life depends on many things, not just mileage alone. Comparing the truck to the car, the oil wore out faster in the truck because it was exposed to more heat, more rough driving, etc...
