here is the latest UOA on my 2006 FX45. while the Delvac1 ESP did a better job of controlling Iron than TDT, i find the rest of the report somewhat disappointing. the TBN is lower than the TDT at a comparable mileage, and this oil is beginning to look a bit tired.

this is the new Delvac1 ESP, and i think it shows they have some work to do on it still. there are some new limits they have to work within for the post processing on diesels. i pulled the sample with the new Blackstone vacuum pump, so the oil is still in there. i did, however, add 2 qts of Delvac to bring the level up to normal (which also is more usage than before). finally, the oil thickened out of grade (very slightly +.2)

here it is

i will be checking the oil again at 15k, which i would bet will be the end of this oil. somewhat disappointing for the price delta vs M1 TDT.
 
Ya know, I thought there would be some more Moly, don't you think...??
 
What weight does the factory spec for your FX? IDK, iron doesn't seem too bad considering mileage on the oil. What OCI's are you trying to attain? How much $ is this Delvac1 ESP?
 
I believe the TBN on the ESP starts low(5 or 6)so retention looks good and one run/application and you think the oil needs improvement,hardly i think it did fine in 10k.

the VK45 engine specs 5w30, as does the nissan 3.5 v6. the V8 is a derivative of the V6 and both are known for throwing poor UOAs. the M1 0w40 did a pretty good job, but i was looking for more, especially in the lower end numbers. the TDT was a major improvement, and i expected Delvac1 to be even better. however for 8.50+qt as a 4 gallon case price, vs 7 bucks a qt for TDT, i don't see a 20% gain here.

was shooting for a 15-20k OCI. the VK engine holds 7 quarts, and the Porsche Cayenne S V8 holds 8 with a 20k OCI recommended (non DI version). with a 2 qt refresh, i suspect it will make it to 15k but doubt 20k is doable with this oil, unless the usage goes up necessitating more refresh (which kinda defeats the purpose).

i am also doing a run of this in my MSM (turbo) miata. that run is currently at 5k, and i may pull a sample at 8k instead of 10k.

with all of my whining about the VK engine and my disapointment with oils, this vehicle is at 101k, using little oil and running like a top. it could be much worse...

TBN of 10.1

This is not an ESP oil in the European-sense of the word. It's an ESP oil in the API-sense, so it's CJ-4.

Ya i had the emission system protection in mind,still did a fine job.

i typically put 50-60k a year on this one, so 20k should be by the end of summer. the filter is a M1-110 M1, which is larger than the stock filter. if the 15k pull looks worth going forward on, i will probably change the filter.

the oil didn't do badly, i just expected a larger improvement over the TDT. perhaps that says less about how bad the Delvac1 was, and more about how good the TDT is....
 
I would consider asking the analyzer to check TAN as well. Your oil may well be already exhausted by the measure of TAN>TBN. I ran Castrol SLX Professional OE 5W30 in our BMW X5 35d 11300mi with 1 qt top-up and was unpleasantly surprised to find TAN 4.83, TBN 1.5.
I'm sourcing some Delvac 1 LE 5W30 (ash 1.0%. sulfur

gaaaahhhh, that's an unpleasant thought i hadn't made it to yet. i will check and see if blackstone still has enough to do a TAN.

i still want a ride in the Unimog.

i haven't tried a conventional oil in this engine, and there are a dearth of UOAs available on the nissan V8. Blackstone's universal averages are for a 3800 mile run and are

Al 2 or 1ppm/k vs my .39ppm/k
Cr 1 or .26ppm/k vs my .1ppm/k
Fe 9 or .91ppm/k vs my 1.5ppm/k
Cu 1 or .26ppm/k vs my .3ppm/k
Pb 4 or 1ppm/k vs my .39ppm/k
Sn 0 or 0ppm/k vs my .39ppm/k

so if you assume Blackstone's UA are dino oils at 3800 miles, they didn't do much if any better, especially if you look at the repeatability of the testing...
 
I suppose if you want to stay with one of the products listed above, I'd go M1 0w-40 at a 12k OCI.

Have you tried a 5w-30 syn and gotten a UOA? I wonder how M1 extended use or PU would fare? Both have TBN's way up there.

At this point, I think I will probably go back with the TDT. Since the 0w40 (normally my favorite) had both higher iron and lead than the thicker TDT or Delvac, I am thinking that an Xw30 would be even worse with the bottom end metals and iron.

I have to admit to being surprised by the oil usage as well with the Delvac. The folks on the various FX forums complain a lot about usage, but this is the first time I have seen any appreciable usage. I think a lighter oil would just exacerbate this issue.
 
For 10,300 miles looks very good to me. All metals are fine and TBN and FP looks good. What's not to like?

Agreed. Although there aren't many UOA's for them, Nissan V-8's (and V-6's) seem to be a bit harder on oil than other engines.

Getting a solid 10k run out of an oil seems to be a good thing, expecting more may not be possible.

These nissan engines both the V8 and V6 tend to give great results with Rotella T6 for some reason. I would give that a shot if it were me.

it's funny, i have converted a number of folks in the miata forum to T6, but haven't tried it in this application. i guess i didn't figure it would do any better than the Delvac1 or TDT. i got a good deal on about 4 gallons of TDT (3 bucks a qt), but after that, i may try T6. i certainly like the new formulation.
 
You're not going to improve much over TDT, so if it's the most available and affordable I'd just stick with it.
