Engine/Transmission (1998.5 - 2002) NEW CI-4 motor oil rating is awesome!!

[FL70CAT]

The new CI-4 diesel oil is awesome stuff!!! It allows the suspension of something like TWICE the amount of soot that current ratings allow, it also has a more alkaline additive package that will keep the oil from getting acidic if we want to run extended drain intervals!!





With the new rating I might actually consider saving money and start buying some DELVAC1300 by the 55gal. instead of the high dollar synthetic oils I have been using.







After using Synthetic I never thought I would consider switching back to conventional... ... but... ..... the new oil rating requirements for CI-4 ROCK!!

 

[DEZLPWR]

Is the Delvac1300 CI-4? How about the Delvac 1? (which is what I use now... . )

 

[Gary - K7GLD]

IS this the new spec oil that allows engines like the new Cummins to do 15,000 between service intervals? What price range - and wonder how the OTHER characteristics of the oil will shake out in oil analysis...

 

[stevek]

I think Delo400 meets the new req now and it did not have to be reformulated...

I have not done a lot of research on this but I did notice the other day at Walmart that the Delo was CI-4 rated and it was $6. ?? per gallon. I will go with the CI-4 next oil change. I now use Rotella T 15/40, but will switch if they are not CI-4 by the next change.

76 LUBRICANTS’ QLT LINE MEETS CI-4 REQUIREMENTS

Yet another reason I go out of my way to buy this stuff, and at a lot less than top self synths.



I use their Semi-syn, Royal Triton QLT.

Ps. This new chemistry is likely a big part of the '03 Cummins have 7500/15,000 intervals vs. our 3750/7500.

I just bought six-one gallon jugs tonight at wallyworld for $5. 60 a gal. (DELVAC 1300)

I'm very excited about the new requirements!!



P. S. I think the CI-4 allows a soot lading upwards of 10 percent by volume!! This is compared to the 4 percent of old ratings??

It also is supposed to have higher thermal stability

 

[Pit Bull]

I was reading the label on a new gallon of Rotella T 15w40. It also stated that it was CI-4. Now why would I spend more for synthetic?

 

[illflem]

Delo was rated CI-4 before the rating even existed. Like what was said above it didn't need reformulating.

 

[JTBMC]

So with the CI-4 rating at what mileage interval should the oil be changed with out an oil sample.

[FL70CAT]

The DELVAC 1300 is not a synthetic, but I believe it is the best conventional motor oil, with rotella in second and DELO 400 definetely in third.

The synthetic stuff is the DELVAC "1"



You could feel safe extending by at least 50 percent on the drain interval. Even at a 50 percent longer interval, the CI-4 oil should have plenty of headroom(protection) left in it

fleetguard and a delo every 3000, for under 25 bucks its the best thing you can do for your truck. why do some of you guys hate to change oil frequently?? I never try to go extended, changing oil on these things is too much fun.

 

[illflem]

CH-1 will not extend your change intervals on an older rig. It's the new engine, not the new oil that allows the extension.

ILLFLEM sez:



"Delo was rated CI-4 before the rating even existed. Like what was said above it didn't need reformulating. "



Not real sure what you mean by that - I just did an oil change on my new truck at 1000 miles, using new off-the-shelf DELO-400 from the local Walmart - when this thread appeared, I immediately went to read the labeling on several unopened quarts left over from that change, and NO mention of improvements linked in ANY way to CI-4 - and indeed, the highest rating on the bottle was CH-4, just as it has been for some time...



I'd like to think you are correct, and I have the latest stuff in my engine - but it's pretty UNtypical for ANY product to be seriously upgraded without LOTS of hoopla and fanfare to trumpet that "advantage" to the customer...

If you really want to extend or eliminate oil changes. I can provide you with lots of information about the Premo oil filter system. The Premo is a 3 micron absolute filter with an evaporative head which removes liquid contaminates. Removing the liquid contaminates extends the life of the oils additive package considerably. The Premo filter is changed every 20,000-30,000 miles and make oil is added as needed. If any one would like more information about these units see the #35 issue of the TDR or contact me at (509) 547-7029 and I will mail you information and a CD.

Untrue, illflem



The soot dispersing and encapsulation is the MAJOR reason that old API spec oils needed changed at the interval everyone is used to. Soot is highly abrasive if not dispersed and encapsulated from causing wear.



If you ran an older engine with old spec oil over the allowable soot lading point, you are basically allowing fine abrasive particles(soot that can't be encapsulated and kept from clumping into larger particles) to wear the inside of your motor.



True that OLD motors don't have as good ring seal as new better designed diesels, however your factory interval for the older vehicle might only be 2,500mi. The new oil will be able to deal with MUCH higher levels of soot than old CH-4 oils could..... sssoooooo I would be quite comfident extending a 2,500 mi interval to roughly 4,000mi.

Or a 5,000mi interval to 7,500 or more if you do oil analysis.

The new CI-4 spec oil IS COMPLETELY backward compatible.





>>P. S. I don't know if Rotella OR DELO400 have met this spec yet, but all the new DELVAC1300 conventional oil certainly does. It is printed on the side up towards the spout end of the bottle.



>> There is a great article on the CI-4 oils in the new LAND LINE magazine for owner operators (OOIDA magazine)

It'll probly be in this month's Road Star as well.

In the website it even states that you can extend drains by 50 percent when you change from a CH-4 oil to a CI-4 spec.

 

[illflem]

I stand corrected. It was my understanding that that the CH-1 oils were developed for the new EPA Phase II engines because more soot ends up in the oil rather than out the tailpipe.



Gary, Delo reformulated to CH-1 specs almost two years ago. Whether they were anticipating the new specs or just did it I'm not sure, but some of their older labeled oil doesn't read CH-1 even though it is.

I drive quite a bit for not being a hotshot. I have logged just shy of 600,000 miles in 8 years. Most of that was on gas engines. I still have a hell of a time convincing my gas brain to change the oil every 7000. Im stuck on 3000. So I made a deal with my obsessive compulsive side to change the oil every 3000 and the filter every other oil change.



I think what illfem said was delo exceeded the new rating before it existed. If the rating doesnt exist you cant put it on the bottle. so the old ch 1 is really ci 4 ,just the rating didnt exist for them to claim it. Ive run delo since i bought it and am very please to hear that they had high quality oil the whole time. Well in excess of what was required. and at 5. 60 a gallon I have been hard pressed to find a better deal.

I know what you mean. I looked at a gallon jug of Rotella T 15w40 a few weeks ago and it had no mention of CI-4. I was then at a AutoZone parts place the other day and noticed that the new gallon jug of Rotella T 15w40 did state that it met the CI-4 proposed API requirements. I think we are in a transition period and that as this new requirement for oil becomes the standard all of these name brands will have the CH-I rating. I read some where (can't think of it now) where most of these oils would have no problem meeting the new spec's. I guess they are slowly starting to advertise this on the bottles. I have been changing mine every 3000 to 5000 miles, with the standard Mopar filter. I am now going to go to 6000 miles since I am using the straphore (sp) fleet guard filter and my driving is mostly highway with the average trip being 15 miles one way, with no towing or hauling involved. Figure that is under the recommended 7500 mile interval for my type of driving. I will save a couple of bucks and should still be conservative. I figure this CTD will out last the rest of the truck
