Interesting read on the oil additive ZDDP (zinc and phosphorous)

Adding ZDDP to your motor oil - Page 3 - TheDieselGarage.com

 

It would be interesting to get a chemical analysis of the Rev-X and ZDDP just for grins and giggles to see the differences in the zinc and phosphorous levels of the two. I'm not a motor oil additive guy either, but as cheap as the ZDDP is, if it adds "life" to the oil (and motor) then it's definitely worth the price.

 

If we could get someone to post up their oil analysis, type/brand of oil, etc for "before and after Rev X", we might get an idea if there is truth to them being the same.

I agree with you Tim, I am not an oil additive guy either, but the emissions limits definitely have required changes to very successful formulations of the past!

 

I'm not an oil additive pusher either, but last year when my engine started experiencing stiction problems so bad that my truck would barely pull itself out of the driveway I had to do something. That something was trying the Rev X and it surprisingly fixed the stiction issue without a doubt.

I don't have any oil analysis of this stuff but if anyone wants to know the true difference between these two additives needs to do a virgin oil analysis (VOA).

BTW... I would'nt hesitate recommending to anyone who has the latest Ford flash with inductive heating and still suffers from cold morning stiction problems to give the Rev X a try. I'm currently not using any Rev X since the Ford flash so far has fixed my stiction issue.

 

I'm also a strong advocate of not using any oil additives, i am a firm believer if you start out with a high quality oil all of the additives that are required are already in the oil.

Now with that being said i am on my second 6.0 with well over 200,000mi. combined and i have never experienced "injector stiction", and i'm suprised at how many threads i run across with people having these issues.

I'm not a believer in luck, so that can be ruled out. I have always run to 7,500mi. OCI's, which after being on here for the last several years I am definitely in the minority.

I just can't figure out why all of the injector issues

 

Roadrunner01,
What kind of oils (Brand & viscosity)have you used for the majority of your 200,000 miles?

Does your current truck have the injector buzz flash and/or the inductive heat flash?

Also runner a thinner oil (ie 5w-40 or 10w-30) will reduce the stiction issue. I'm maybe wrong, but my opinion is cold temp stiction problems mostly occur with 15w-40 oils. Having said that, I don't recommend 5w-40 oils because it caused my engine to leak oil something terrible, but it did eliminate the effects of injector stiction. I think these 6.0 injectors prefer a thinner oil for proper injector operation.

 

other than the last three runs on 10w-30 (and the three proir runs of 5w-40 RTS) all of the other oc's were on john deere plus 50 15w-40.
as far as my latest programming, my ficm was replaced last winter and my programming was updated at that time, so as far as i know its the latest available.

 

As you posted elsewhere, the ZDDP was in fact reduced or eliminated due to the plugging effects it has on DPF's. It's long been known that ZDDP is a catalyst poison, and has been slowly reduced in oils for years.

Given the numbers on that thread WRT levels in current motor oil, I'm not sure it would ultimately do any good; however, there may be a "threshold" value that shows benefits.

Note that ZDDP is an extreme-pressure wear additive. It is commonly used in oils for motorcycles where the engine and the transmission share the same oil; indeed, motorcycle-specific oils go for $4-$6/qt, with this stuff at 1980's-high levels. Motorcycle enthusiasts were crying foul over this a decade ago. The first suggestion to alleviate the problem was to go buy diesel motor oil. This was when Motorcycle oil was $4-$5 a quart, and "normal" automotive oil was still $1.79 a quart.

Gears in motorcycle transmissions are often subject to the same kind of face loading that our injectors are subjected to. Another thread to pay close attention to.

Was the JD 50 plus a CI4 + or a CJ4 oil?

 

currently its CI-4, i have enough for 3 more oil changes and then i'm on to CJ-4.

My dealer made me a deal I couldn't refuse on the 10w-30, so I took all they had in stock, 11 bucks a gallon.

 

Great info Bismic; I use to add zddp in my '88 460cu. motor because of the old style lifters and cam. Newer motors have roller cams instead because of the lack of zinc in oils.
I think I still have some zddp in the garage and will try some in the 6.0. I noticed a slight rough idle in the motor the last week so it will be interesting to see if there is a difference. Since my cat died years ago at the hands of previous owner I have no risk of damage to it... I often wondered what it would hurt to add to engine oil in the diesel motor...

 

P.s. Please keep us posted what your freinds on the other site learn as they use the additive. Thanks again. Doug.

 

It used to be CI-4, I looked on their website today and its been changed to CJ-4. Too bad, it was a great oil.

 

What makes you think that going CJ-4 will hurt it??

 

I believe it was in the link by Bimic that the new oils will have less zinc due to the dppf exhaust systems...someone correct me if I am wrong, but that has been the reason for the reduction in all oils over the years..
