I read that Chevron Delo 400 CJ-4 is due out mid-october, but what about Shell's? Any others out now?

CJ-4 sounds like a superior oil to the CI diesel oil out now, so I'd like to migrate to it as soon as it's available....

Thanks for any info y'all have to share...

 

Here's the Shell FAQ: www.rotella.com/press/article_66.html


#15 states it began distribution in July though most people say we'll see it around October or November on the retail shelves.

 

I don't think I would be in a big hurry to use it. Actually, if I had a diesel, I would be buying up all of the CI-4+ I could. Here's the issue. The new formulation will not have the TBN that the older oils will have which means you are going to be changing oil more often using the standard grade diesel fuel. Once the low sulphur fuel is out the problem will disappear but until then the sulphur in the fuel will be turned into sulphuric acid via the combustion process and you will be changing oil at 3500 miles or expect damage from the acids. Again, the TBN will be lower, for most oils around 8. But the acid making sulphur is still in the fuel until the low sulphur fuels are out. Conversely though, when you start using low sulphur fuel, you need to change over to the new oils or you could get into to an overbasing of the oil which will cause calcium deposits to form on the cylinder walls and oil usage will be the first sign, second sign is engine siezure which I really don't expect to see a lot of but it is a possibility. Just remember the type of fuel and the type of oil needs to go together as one package.

 

CJ-4 has been out since july here but it is only being sold by chevron around here. it is being sold in the new bottle with bright yellow writing.

 

""Conversely though, when you start using low sulphur fuel, you need to change over to the new oils or you could get into to an overbasing of the oil which will cause calcium deposits to form on the cylinder walls and oil usage will be the first sign""

not an issue LOW sulfur gas has been around a long time and lot of Multi fleets use Delo 400 CI and CH with a TBN or about 12 or so and NO problems "glazing" CA is a non issue more perhaps is plug fouling from high ash tho.

Also the line ""get into to an overbasing of the oil""
makes no sense at all.

Let's see Bruce, you have 23 posts and most of those are aimed at my posts. Ya gotta problem? The post is in regards to diesel, as in and oil based fuel, not gas. I highly doubt you have a clue about overbasing or your comments would be entirely different.

 

If the CJ4 will help when the 15ppm diesel hits, then I could use it now. CA mandated switch-over by Sept. 2nd, and so far all the pumps I've looked at show the new 15ppm labels (along with the new higher prices for said fuel )

I'll have to look for the yellow symbol on the bottles. I usually by Delo by the case at Costco, so I'll check there 1st.

Thanks for the info!

 

""Ya gotta problem?""

No but I know the lube industry well and when I see mis information I will post my take on it.

Please take no offense I know what overbased additves are and the line makes no sense like he is adding a overbased CA and making his own oil I know what you are trying to say but it sound funny, whatever.


I just post my opinions and thoughts on HDEO and PCMO as well as industrial lubes we disagree on some items others we are 100% in agreement.
Do not mean any harm just posting MY experience in the field.
Take it as that.

Also as I said earlier you can not make a 5/30 with just GPIII oil and NO VII
but if you know otherwise please tell me it will save me a good amount of money I now spend on VII.

And Do I have a clue yeah

Bruce knows his 'oil' stuff. He's a regular at bobistheoilguy's theoildrop and Noria's websites.

I can't wait 'til this oils are more common. I use HDEO's in my cars.

 

Ford390: just want to be sure we're talking the same thing, here -- I just picked up some Delo 400 that has a yellow tag in the corner of the label that says (something to the effect of): "new reduced friction formula"

But the rating is still a CI-4+ (not CJ, yet). Would you mind looking at your bottle again and just make sure it's a CJ rated oil you have? Thanks....

I am somewhat expecting the CJ oils to hit in CA 1st, just not as early as july...

 

If you have an older or current truck you can run CI4+ or the new CJ4 motor oil with no problems. If you have one of the new MY 2008's with all the new EPA mandated particulate filters than you can OLNY use the ULSDF 15ppm) and ONLY the new CJ4 motor oil.

Current diesel owners can use the new fuel and old oil.... they do not go hand-in-hand. The new oil is only for the new trucks, but is backwards compatiable.

 

I still have 2-3 case of CH-4 left. My 7.3 runs just fine on it. No EGR, so it really doesn't need the extra soot control that the CI-4 has.

But my CDI does require CI-4. I have 3-4 cases of that left.

I won't be throwing any of it out.

 

Bore polishing was never caused by metallic calcium being deposited on the cylinder liners . Now that even less metallics and different dispersants will be used in the new CJ-4 oils , even less bore polishing will be going on from the one and only known source/area .

TBN in comparison will still be quite high with the semi ashless additives .I expect TBN of 10 or so with many oils . The Motorcraft 15w-40 has been built very similar to these new oils for a couple years now
" low sulphated ash " and has good TBN . Newer salycate detergent formulas will start with lower base numbers yet have superior retention vs overbased sulphonates so it seems while offering better wear protection .

Also ,the new diesel fuel per white papers will be doped with a lubricity additive that has a polar head and will impregnate into the upper liner , especially so since the diesel engine gets the fuel shot much later in the stroke and closer to top dead center than a gas engine , there will be very little surface area to be concerned with and that area should be protected well .

These CJ-4 oils will be some very good engine oils in a viscosity thats still too viscous for most gasoline engines .

 

well. tomorrow is the 20th, cj4 was supposed to be released on the 17th of oct., anyone seen the new CJ4 rotella out in the stores. i plan on looking this weekend. I have always used a drum of oil, but for my new truck i want to use this new cj4 for my first oil change.

let me know if any of you have found it, and what stores it was in. we have shell gas stations around here but none of the parts stores have shell rotella. maybe wally world has it?

 

I'm not sure if anyone posted this in any other area of this site, but I did happen to be in wally world this past weekend, and just happened to walk by the oil isle and see the new rotella T, rated for CJ-4 it was like 8 something, maybe 9 a gallon.
