So RAM figures people 30k a year? We are going to be pushing it to put 10-12 k a year on our new RAM. Sorry RAM, I am not going to throw away good oil at 6 months. Sounds like quick lube and 3k changes.
I did change it the first time at around 4.5k or something like that. Chris
I hear and understand you. My thought is that if they want it that way, there is a reason. Secondly, I'd hate to loose out on a warranty for an extra $100 dollars a year! Sounds like cheap insurance to me...The point I am making is that if Joe drives 15K in 6 months and I drive 5K in the same 6 months, are both on our oils at End of Life and need to be changed. On a pre 2013's I could understand it, however on the DEF trucks I find that excessive.

And if the 6 month interval is the magic "end of life" for oil then I am sure all dealers round up all the unsold new trucks in their lot (with 27 miles on them) and change the oil if the manufacture date of the truck is 6 months prior. Forgive me for being a smart --- but how does storing oil in a crankcase make it go bad. Now I certainly understand condensation issues if engines are started and not warmed up completely before shutdown. Short trips are not good for oil. It would seem to me that an algorithm in the computer should be able to log engine use information and calculate when changes are really needed. Don't get me wrong I will follow the manufacturers recommended interval but I agree with Snoking on this one. What about the guys with motor homes. Drive 500 miles to an RV park and sit for 6 months. I doubt the oil in that engine needs to be changed unless he is idling every day to charge batteries.
There has to be some common ground on this. I am guessing the manufacturer is just being safe and cautious with the six month number since they don't know all the variables a particular engine is exposed to.
Time, by itself, breaks down oil while it is in an engine (I added that last part so Newsa won't start looking for date codes on oil containers).
I'm not sure why people can spend 50-70k on a truck, then are reluctant to spend less than $100 twice a year even though the manufacturer recommends it.
While I'm under RAM's warranty I'm sticking with the book, every 15K miles or 6 months (or 500 hours). Does it NEED to be changed at 3600 miles (my last mileage at 6 months)? In my opinion no, but, its RAM's warranty and they say it does. After the warranty is over I'm going to once a year or 15K miles.
