Interesting oil article - Page 2 - Diesel Forum

One thing I noticed in the test with the Lucas additive is that they used the standard Lucas. Also, in the pics and description there was no mention on the ratio of additive to oil. There is no denying the ability of the Lucas additive to add "climbing ability" to the oil. I believe this is a good thing. As far as the airation is concerned, which is obviously bad, this may be due to the ratio of additive to oil. As I mentioned before, it would be nice to see some other testing of additives. If anyone has some links to any, please post. I just don't see why an independant lab that tests oils, Blackstone, would recomend that I use it if it was not any good. They have nothing to gain, and customers to lose by their recomendation.

As I mentioned before, I have been using Lucas Synthetic in my OT car for 2 years, no problem. One quart with six of 5w30. No issues. I am currently waiting for my latest oil sample from my '02 diesel. I will post the results when it comes in. Also, I have checked my oil frequently since seeing the pics of the airated oil in the Lucas test pics. I checked it while the motor was running and right after shutting it down. Specifically looking to see if my oil appeared to look like the airated oil in the pics. My oil looked just like it had before I was using the quart of Lucas additive.

The debate rages on.

I would only put it into a crankcase if I had a bad bearing and I just had to get somewhere to tear the engine down. It is absolutely bad for Powerstrokes due to the HPOP.
Their "Synthetic Oil Stabilizer" still has a viscosity >40 cSt at 100 C., which is about what 180 weight gear oil is rated at. Lucas says it's OK for Powerstrokes....I don't agree.
Incidentally, analyses of these Lucas products posted on BITOG show they are nothing but very thick oil.

Yes but it is kinda ashame that people are still "Hypnotized" by the claims and Hype of these products.Oh well it made Lucas a Millionaire Lol!!!!!!

being a dodge owner also, i'am a member over at the tdr, this article was in the quartely tdr publishing about this time last year. the biggest issue goat owners have with these newer oil's is the additives in the oil. the newer oils lack additives that the solid lifter useing 5.9 cummins and some others engine with solid lifters need. i have been useing both rotell and delo in my diesel powered stuff for more then 30 years. based on this article and some follow up info, i now use oil's with the older rateings[cant find just anywhere] in my cummins powered trucks /equipment. from what i can tell, i will continue to use the rotella and delo oils in my powerstrokes.

I used Motorcraft for 2 years, then switched to Rotella because of this site. As soon as I started using Rotella my truck started using oil.I continued to use Rotella for a year and the consumption continued.

My neighbor has a Dodge and uses Valvoline Premium Blue so he talked me into switching. I switched and BAM,the oil consumption went away after the change and I have been using it for over 2 years without a problem.

I am not a fan of Rotella and am a huge fan of the Valvoline Premium Blue.

Are you now using the Delo 400 LE CJ-4, because thats all I've been able to find these days. Is Multigrade CI-4 still available ?

delo ci pretty much dried up in my area a year ago. since then it's been cj oil only. shell ci dried up sooner then the delo did. as it stands i have one truck left useing shell oil. when i start my fall oil changes, i will phase out the rotella, and stick with delo, rotella syn, and tractor supply's traveler brands. traveller brand is still the ci formula, and i have been useing it for years in some of my stuff anyway. really would like to know who makes the tractor supply oil...

Just got my oil analysis in from Blackstone. Here is what they had to say in there comment section

"Nothing unusual showed up in this sample from your 7.3 diesel. Universal averages show typical wear for this type of engine after about 5,300 miles on the oil. This oil was used longer than that and wear compares very well with averages. In fact, nothing in this wear pattern shows anything amiss inside this engine. The 6.8 TBN shows lots of active additive left. The viscosity was 15w/40 and the trace fuel is a nonissue at this level. Try running 8500 miles on the next oil and check back."

My sample had about 6,500 miles on it. I used 14 quarts of Motorcraft 15w40 and 1 quart of Lucas synthetic additive. Based on this sample I am going to stick with my current oil and additive brand and change my oil at 7K miles next time. I would like to try the Valvoline Blue that rated high in the test, but I can't find it in my area. I also usually change the oil at 6K miles. I just happened to run over this time. Good to know the oil could take it. As far as the argument against Lucas. Well, it did not affect my oil weight in any way. I think the test mentioned earlier was not very controlled. Ratios were not at Lucas's recomendations and that video used the standard Lucas, not the Synthetic that I use.

I getting ready to make the first oil change in my '08. I'll let you know what I find in it.

Also, I am sending a sample from my race car in to see how it fared. It is an open track car that sees 25 minutes of sustained 5K rpm use. I use sythetic oil and Lucas Synthetic additive in it. I'll let you know how it turns out as well.

I'm surprised the Test didn't include Delvac-1 by mobil. I've used it for yrs. all the local Trucking companies use it. I read an article about 10-yrs ago were the Army used Delvac-1 in the Bradly Fighting Vehicles and in one report they tested it for 800 hrs, with No brake-down of the oil. In 2003 a young man moved into my neighborhood, he was just out of the Army and was a mechanic on the Bradly's and confirmed the use of the Delvac-1 so I stayed with it.

I heard that the John Deere oil at tractor supply stores is still ci rated and can still be purchased.Just thought I would help spread the word.

Delvac 1 in CI4+ form is hard to find in the US, most of it is now Delvac 1 ESP which is CJ4. John Deere +50 15W40 is a great CI4+ oil, with P>1400ppm if you like ZDDP.
There is also an excellent additive to "soup up" CJ4 oil, called Redline Breakin Additive. It has 20000ppm Zn and 17000ppm P, also 20000ppm Ca (I think it's detergent/antacid).
It needs to be used carefully. In a 15 qt pan 1/2 bottle will raise Zn and Ca by 300 ppm, P by 260ppm. Since CJ4 oils are defined as <1200ppm P, most are ~1000-1100, this is about right.
Raising the Ca level by 300 will raise TBN by ~1.0 if it is indeed Ca sulfonate or phenate detergent.
