Does anyone have experience with this stuff? If I understand correctly, ZDDP is a zinc/phosphorous compound that makes some of the injector stiction treatments work. Apparently, this a completely different compound available in my local auto parts store and advertised as a ZDDP alternative.
With the weather getting colder lately, my choppy cold idle is coming back. I tried RevX last year and it made a noticeable difference so I'm confident it a stiction issue. I've had two oil changes over the summer so I'm sure the benefits of the additive have petered out. No luck finding anything locally with ZDDP.

Manufacturer Information
Hy-per lube Oil Supplement was originally formulated by Harold Hilton in the early 1950's. Mr. Hilton fabricated high quality valves for a wide variety of industries, including the paper and pulp, electrical power generation, petrochemical and marine. The enormous amount of heat and friction generated by the worm gears within the valves was causing premature wear and failure. Finding no commercially available lubricant that was suitable, Mr. Hilton set out to develop a lubricant that met his needs.

The result was the development of Mr. Hilton's hy-per lube,a high film strength, non-foaming, extreme pressure, non-corrosive, oil stabilizer. The name hy-per lube is found on the shelves of virtually every automotive parts store and distributor in the country. Hy-per lube has a proven record of providing maximum performance and ultimate protection for over 50 years.

Rotella and other CJ-4 oils have plenty of zinc.

I think your stiction issues arise from still using the as delivered FICM/ECM strategies which did not address the stiction as the later ones.

Are you using 5W40?

Josh

 

Rotella T6 (5w40). There are quite a few threads on the subject of stiction and oil additives and I think I have read all of them lol. Just looking for a reasonably priced band-aid I could pick up off the shelf.

 

The band-aid is to update the strategy... which is the bummer.

Josh

 

Stiction, once it is occuring, is not usually permanently reversible - even with a strategy update. Since it is related to polishing the inside bore of the injector spool valve over time, several bandaids may be needed to give the temporary "relief". Ultimately the solution is a new injector IMO, but additives have helped quite a few folks. Finding a cheaper one is always a helpful contribution (as long as someone is willing to do the research and take the risk).

 

Diesel oils can range from 750 ppm zinc to 1500 ppm zinc (1000 to 1250 is more typical though).

So - what is "plenty of zinc"? How much is that? How does it relate to the amount of detergent that the oil contains? Do emissions systems or engine temperatures play a part in the answers?

In some oils Phosphorous and Zinc content is being regulated (well the P is being regulated which then regulates the Z indirectly as I understand it), and oil formulators are usually trying to keep costs down ............ so, how does one go about figuring out he has too little, plenty, or too much.

 

Which diesel oil has under 1000 ppm zinc besides the garbage Delo LE? CJ-4 is regulated different than SN/GF5 gasoline motor oil.

Keep in mind, the OP is running the VXCF1 strategy, certainly the Buzz flash or new Induction flash would help with the stiction issues.

I have never seen an oil report for Delvac showing below 1100, pretty sure the general consensus on BITOG would show an average of 1200.

I personally do not keep up on the "boutique" oils like Amsoil, Royal Purple or the like.

I do know Rotella very well, having sent well over 8000 UOA reports.

The only "major" oil I personally have seen with low zinc and phosphorous numbers is Delo LE.

Josh

 

Here is an older article that lists the Delvac at 1028. The Amsoil was 947.

Anyway, as stated, they are typically 1000-1250 ......

So the question is - is 1000 enough? Is 1250 better? 1500? When does it become too high for the dispersant technology of the oil?

 

Here is a recent Delo LE data sheet - looks like they bumped it up to 1270 ppm zinc.

You're basing Delvac's zinc levels on one report (skewed BTW) and not the hundreds available that show 1100+?

Here is one right from FTE:

https://www.ford-trucks.com/forums/9...000-miles.html

CJ4 averages 1100
CI4+ averaged 1400
CI4 averaged 1500+
CH4 was a crap shoot

Josh

 

Well, I was going to base my opinion on Delo LE on one report (or post) .............. until I saw the data sheet - lol.

I suspect that formulations change over time. Some for the better and some for worse.

I will say that I will take a VOA over a "spot UOA" anytime. There is also residual oil when a person swaps around a bunch (OP in your link). Also the VOA posted later was hard to tell which Delvac it was.

I admit I don't keep track of it very closely anymore.

 

I actually wasn't even thinking of Delo 5W40, honestly didn't even know they had it. The 15W40 Delo LE has a bad rep, especially compared to Delo 400 NG.

Possibly Delo became a little wiser?

In regards to Rotella, there was a trend in late 2006 and early 2007 to reduce zinc with the introduction of ULSD in Fall of 2006 and introduction of CJ4. But it wasn't long that zinc levels went from high 1000s/low 1100s to back into the 1200s and I have certainly noticed the trend that zinc levels have steadily increased from that time.

To the OP, sorry Bro!

Josh

 

Looks like the delo 15W40 is up to 1300 ppm .........
