We all have our own ways of doing things and beliefs. I have always used a littler heavier oil than required but with the new engines now days tighter clearances I'm having to rethink some things. I still use a littler heavier oil in my vehicles but they all have over 100,000 miles on them and I figure they have loosened up over the miles.

Both of you need to cool down. I'm gonna step in here before this gets out of hand.
Auggie: You actually were the one who insulted him first, calling him cheap, and the rest of your post was dripping with sarcasm. He is a moderator, and so he was a bit rougher with his reply than he should be, but please don't cry foul when you were the one who threw the first stone.
Laramie: You didn't help the situation replying the way you did. You have a right to defend yourself, but you could have attempted to diffuse the situation a little more.
Both of you, please end this now and be a little more civil.

Rotella makes regular motor oil too..I've used it in my vw.. 50w was oem spec on my vw 40 years ago....but most dont run it anymore on higher reving vw's because it robs power and its so thick it actually has an issue bypassing the oil cooler....its doesnt do anything for performance or efficiency in our v8 motors but hey if your that cheap....Then again why are you spending so much on gas driving a ram if money is that tight?
In reality you would be better off with 10w 30 from the dollarstore...really the oil is the right thickness and performs ok it just doesnt have all the fancy additives to help protect the motor from wear. I dont believe most diesel oils have it either since diesels are low reving motors....and they have different contaminants in them when ran in a desiel engine so the additives may be different because of that fact as well.

My Thoughts Expanded.
My point here was that just because a manufacturers says this is what you should be using, does not mean that that's actually what you should use. Their recommendation is usually correct, but it does not mean that it is the only option.
IF you look in the factory service manual, it will say that you should use MOPAR oil and MOPAR filters. Now, for those of you that didn't know this, MOPAR is a business and they care about the bottom dollar. What you get in a MOPAR bottle now will probably not be the same a month from now. This is why I never liked the idea of anyone taking a vehicle to the dealer for their oil changes. They buy by the barrel and the brand of said oil will change every order to keep price down.
With the magnum motors of old, it was not uncommon to see people using a straight 50weight oil with no ill effects. Sure, just sheer flow resistance will rob power, but you can't for one second believe that the differences between a 10w-30 and a 15w-40 is all that great. The weight differences are not enough to have fear of the extra weight causing premature wear or extra force on the bearings. Which, lets face it, in terms of oil, that's your main concern.
In my case, I run Rotella for two reasons. One, I buy by the 55 gallon drum so it's cheaper for me, but this is not the deciding factor. The deciding factor for me is that with new EPA laws and the greenies, you see oils becoming low sulfur. Sulfur is the main ingredient in motor oil to protect against wear. Rotella is one of the few well known oils left that still have a high sulfur content in their oil. Couple that with the cost and the fact that I commonly see diesels and other heavy duty motors going 300-500K miles before needing any kind of major work done on them, and my point becomes clear.
I do agree that with new motors it may not be the best of ideals to do what I'm doing. Take the 2006+ 345ci Hemi and the 2007+ 5.3 GM motor. They both employ similar variable valve timing systems that will disable four of eight cylinders while the vehicle is at cruising speeds to boost fuel economy. In the the case of the Hemi and probably the GM ( Haven't looked into the 5.3 for obvious reasons) Dodge says that you should use and only use a 5W-20 weight oil. The VVT system relies heavily on the oil weight in order for the system to engage and disengage correctly.
That brings me to my next point. Those of you that run AMSOIL, listen up. If you are concerned with oil weights, you might be interested in knowing that AMSOIL's viscosity will change over time. There was an independent study on this issue. (Search google if you want to learn about it) In short, the testers used a 5w-20 oil in either a fire bird or camaro and drove X amount of miles on it. During the segment, they did various oil samples and analysis. At each change, they found that the viscosity was slowly changing. The oil was becoming heavier. At the end of the test, the last oil sample showed that the viscosity was sitting at a 15w-40 weight oil when we started with a 5w-20.
In the end, don't over think oil. Research it, and use what you think is best. Just know that beliefs will change over time and there are good and bad oils on the market. Also never forget that the environment and use of the vehicle should influence your decision as well. I wouldn't for one second expect the same motor in Alaska to run the same oil that the same motor runs in Texas. Heat and applications tend to call for a heavier oil, while cold and lighter applications will allow you to get away with a lighter oil.
Might I add still that Castrol motor oil has one of the lowest wearing additive ratings on the market today as of testing completed in 2009.

Good god chris thats a book, i'll have to say iv used castrol alot in the past and never seen any side effects from it, the oil look a little cleaner coming out with the same amount of miles between oil changes.
Who knows who cares as long as we give a damn about what we put in it and check it regularly thats all i care about.
