Exhaust Gas Recirc EGR puts a lot of Soot in the oil... the oils are designed for this.

 

I was reading that the CI spec oils are slated to be discontinued around 2010... CJ oils will be the only one around for us.

 

Yes, yes, and yes. I'm pretty sure the only reason 15w/40 is even still around is because it's alot cheaper for fleet service operations. And there seems to be alot of people that like to change their oil plenty often, whether they do it themselves or use the quickie lubes. Otherwise, there'd be no market for it.

It's no good for cold climates. Why are you driving a $40k truck if you can't afford good oil? Penny-wise, pound foolish.

 

From 04.5 on up you have a extra injection, causeing the oil to go black.I have a early 04 and after 2100 miles my oil is still pretty much golden on the dip stick.For you guys its normal with that extra injection.

 

That's interesting, I was told that by a couple of the local guys a while back as well.

 

If your oil is going black its a good thing (oil is doing its job) its called suspension. If its staying clean for long periods after the change it probably means you dont have enough bombs done to the truck to create extra soot LOL.

 

5.9's don't have EGR and you can still find CI-4 oil if you look for it.

 

5.9's do have the 3rd injection event that makes the oil black. I have found that John Deere makes a CI4+ waiting to get my first oil sample back from it . They will continue to make it as most of the applications are for farm equipment off road..

 

Here's an industry article talking about the shift to CJ-4... and it discusses how they made it backwards compatible even with the reduction in the traditional anti-wear components of older oils (ZDDP).

lets all get up to speed..

 

why do you think the economy is in the shape that its in? people buying things they cant afford and the banks lending the money thinking that some day they may be able to pay it back

 

does a 2004.5 have egr? is it the 3rd injection event? and wha is the 3rd event and when does it get injected? i know theres 2 events before it.

 

Interesting link and read. Basically they are suggesting that the reduction in sulfur with the 15ppm ULSD fuel allows the oil to be downgraded to work with the newer emissions systems and still provide adequate protection in pre emissions engines. I also noticed they mention the correlation between ULSD and shortened fuel injector life...Great.

For the old engines, it wasn't broke, but it might break sooner with the new oil. I think at my next oil change I'll be hitting up the agricultural machinery dealer for some proper CI-4+. I've been doing 3K mile changes with Rotella 15w-40 CJ-4 since I got the truck in June 2008. Hopefully the damage isn't already done.

They'll probably write an article in 2010 discussing that between the new oil and the new fuel the older engines only last 50% as long. Unfortunately the consumer will be screwed into paying for a new motor or some updated components to work with the new oils and fuels. I remember having to redo the fuel lines on my dad's boat when they switched to oxygenated fuels in the late 1980's.

 

Wonderful. I just serviced my truck and put that CJ-4 crap in it. I didn't even pay attention, but I noticed that the Delo bottles said "low emissions" on them. I already want to take it out. Is there anything that Al Gore isn't running these days?

I'm going to find some CI-4 and stock up.

 

Arizona Machinery in Avondale is a John Deere dealer. I'm thinking that they can provide the CI-4+.

 

So, I've helped ruin the economy because I'm using RTS 5w/40 or the because I'm driving a Dodge Cummis? Or both?

Sorry, I didn't quite get that.....
