TDR Oil Tests

[JDecanter]

I was sure by now somenone would have responded to the results of the TDR Oil tests showig amsoil as either acceptable or ho-hum based on additive packaging. So, how about the report: was it apples and oranges or not? I have been using amsoil for 25 years, but I am about to change to one of the better performing oils. I would also like to see the additive package for 15-40 diesel oil.

That Amsoil they tested was the newer CJ-4 oil so the 15w40 stuff you're using might possibly end up alot higher on the chart. I'd also like to see a test of the Cenpeco oil to see how that stacks up.

I have been running amsoil and beleived that it was superior to almost any other oil on the market. But when they it tests at the bottom of the list in that catagory that is alarming, you would think they would out perform the others. Even though they didn't test the 15-40 that I use it is making me question thier claims to be the best.

I was walking through a local Walmart and found 10 gallons of Rottella T synthetic CI-4+ for $16. 50 a gallon. I bought all of it

Personally, I was encouraged to see that virtually ALL I and a few others have been saying about various oils - and especially the new CJ stuff - was right on target with the findings in the TDR article.



I further still believe we will relatively soon, see either modifications to the CJ stuff - or else a new "CK" version to improve on the CJ.



The CJ stuff is probably OK in engines where the oil change interval is not overly extended - but I'd sure hate to use it in engines that sit thru a winter or in other situations where the additives previously provided protection the new stuff doesn't...

 

[MVieira]

I agree with Gary also.

Factory fill?

My truck was built 10-16-06. Makes we wonder what the factory fill was?

Amsoil has some good products but I have also felt many were a little overrated. I did have a bad expeience with Amsoil ATF in my 90 T-bird Supercoupe, after about 15k on Amsoil the transmission self destructed, that was at 28k on the odometer. Back to Mercon (IV, I think), got over 100k on that.

IMHO, I'm not really relying on anyone's "opinions", even those of TDR.

If you read some of the oil forums on the new CJ-4, they indicate CJ-4 is about the closest a conventional oil has came to a synthetic. As someone else once stated on this topic: will it mean we only get 950k on CJ-4 versus a full million on CI-4????? I highly doubt there will be a clear difference in the mileages obtained on a fleet of rigs...

I think the most critical demands upon engine oil is not in fleet, OTR usage, but in the short haul runs, mixed perhaps with erratic longer periods of storage or non-use - perhaps over the winter season.



Otherwise, I pretty much agree that the potential loss (if any) with the new stuff will still leave an engine that outlasts the original owner... :-laf

Darn you, I was only able to get the last six at my local wallyworld.

Gary, agree; Worst driving is short trips where the oil does not reach operating temperature, and remain there long enough to burn off moisture and fuel vapors...

The coolant oil cooler also has the effect off heating the oil. but it takes
quite awhile to do so in cold weather.

My understanding is that 180-200 degrees is the optimal oil temperature.

I didn't read every word , mainly focused on the results , I have been getting set up to change to Amsoil , after installing a twin filter -dual by pass , after the last few oil analysis running Rotilla T 15w-40 & getting very good results , average to slightly below metals & high TBN -9++ with 12,000 miles .
I started to think that just putting in the bypass system & see what testing came up with .
Then reading the latest artical , & noticing that it seems like they did not give enough description of the Amsoils to now witch on they were talking about , just using weights to say what oil was what , vs more terms on the container to make more - I remember my gal jugs saying marine , heavy duty , maybe that is just sales , the point being that I was not sure if the Amsoil I have is the same as the tested oils ?
My 2nd point is that , my Rotella tested very good , & I thought that I had come up with enough info to go to Amsoil , and now this artical does not seem to match with what I've seen , so more looking into this is where I'm at now .

The silence from the Amsoil Zealots is deafening.....



On a serious note, the results of my used to be beloved Delo 400 burns my ***, but what can you expect from our crack EPA and predatory oil ?

 

[BTowler]

The EPA is not your freind! Their job is not to improve the environment, but to force technology. Perfect example, to reduce emmissions the EPA does not say "Here are the specs you have to meet, come up with a solution. " They say "This is what you have to do to your vehicles to meet our standards. " Many times this has more negatives than positives, look at the mileage figures on all the new trucks coming out, consistently down, yeah less polution per gallon but more gallons burned. Does anybody really think what they have done to the oil will be any different?

I emailed the Amsoil Tech support. They offered to give me some testimonials but said thier additive package was propriety information and formulated for each application.

I'm just beside myself with these oil changes. My beloved Premium Blue ain't so premium anymore!

I have no idea what I'm going to do when my small stock of CI-4 runs out (2 more changes, I think). No idea.

Maybe it's time to consider adding your own additives? I wouldn't have the first clue what to add.

I'm still not convinced the CJ-4 oil combined with the use of ULSD is really as bad as what is believed...

Easy now... the sky is not falling The CJ-4 will not make the engine wear out! After all, unless you are really extending your OCI's there is plenty of additive in there. I had both a VOA and a UOA done on my CJ-4 Rotella. Had a 10. 3 starting TBN, at 7,400 miles 8. 3 TBN on the UOA. So retained the TBN very well. Here is a link to my latest UOA on BITOG. You can also supplement your CJ-4 oil with some CI-4+ for an additive boost.

Yeah, I know. But I just loved that Premium Blue formulation, and now it's gone. It's like I've lost a beloved pet or something.



I felt so vindicated all these years running PB when the TDR article came out. I guess if it will still carry the Cummins logo I'll continue to run it.



I feel like the end of the movie Ricky Bobby when Ricky tells that other dude that it can never be "Shake and Bake" again, it's gotta be "El-Diablo and the Magic Man". The end of an era. :-laf
