Gde tuned Crd engine oil

thermorex · **Posted:** Thu Mar 12, 2015 5:43 pm

This is just for the non-believers, proof how the oil looks like after 4000+ miles, winter drive (oil changed mid November 2014), mostly driven 10-ish miles one way.

Top smudge on the napkin is me wiping my hand from pic 2, mid left is a drip of oil from the dipstick and bottom right is dipstick wiped out on the napkin.

I think the greenish color is because of GREEN diesel tuning, made the oil with a tint of green... Lol. Btw, Mobil 1 0-40 oil.

Yep, very similar to what comes out of mine after 10,000km. Before GDE it was jet black after just a few hundred.

Must be FRIDAY 13th, because strangely enuff, I still cannot find where MOBIL 1 has achieved API CI-4 rating for turbocharged Diesel engines - or CH-4 - or CG-4
- it does, however meet API CF ratings for HD spark-infested engines - SJ, SL is for turbocharged versions, not nearly as HD as Diesel versions, is now included
with CI, CH, CG to let sparklers know they can run the Diesel-rated oils

The FSM is very ambiguous in this area, not specifying API gasoline-specific ratings, but mentioning the gasoline-rated SL,
SJ MOBIL 1 below the Diesel oil paragraph - seems to be a 'nuther FSM misteak, of which I have found many therein...................

Mobil 1\equiv could be one causative for the many rocker-arm failures noted when MAF-readings are taken and the head-cover is removed

I have been running only diesel rated oils for sometime. We have Canadian sourced Mobil 1 0W-40 TD oil in now for the winter (comes in litre bottles and is VERY expensive). My question is, is there any other difference between the oils other than additives to handle soot? So, if you run the readily available 0W-40 with no EGR so you go 3-4 K before the oil starts to get any color to it and you change it at 5K, does it really make any difference?

I did my own test and displayed in on Sprinter-Forum, where we have a few enviro nazis, and a bunch of guys that will not mention their GDE tune, it was called the Great Dipstick challenge. I had no takers, but here is mine. One guy said it was not good enough without analysis.

The first one on the right is a non tuned Sprinter, the other 3 all tuned. Engine mileage on the top, second line is oil mileage.

I'm fairly certain that, in addition to enhanced soot control, the rating is for stability at higher temperatures than gasoline-rated SJ\SL oils

By my reckoning they seem to have lost something in the translation from ACEA to SAE.
It is an Italian motori after all - just at the time owned by a non - Italian company.
They both are fair systems for describing oils but do not interpolate well.
Indeed I aim to use an E7 rated oil (in the ACEA system) which is rather heavily designed to cope with that awkward beasty the EGR correct - specs of course.
You use the best you can.
I'm happy to go to the trouble of importing the correct trans fluid - not doing that with engine oil if I can avoid it.
Dabbled in some chromatography but need to find better paper that will allow greater separation of fractions.

Nice work thermorex. My oil looks like yours at that mileage. That is a far cry from the black ink that used to be the norm before my GDE tune.

How many of you are having oil analysis performed by companies such as Blackstone?

I've read extensively on this site about rocker arm failures (mine is bad at the moment but soon to be repaired) and wonder if the problems seen in the valve train on these engines is actually belt related or rocker arm failure caused by oil...................and the belt is simply a symptom of a deeper root cause. I'll be performing LOA starting with the first oil change after repairs......and running a GDE tune of course!

It may be easier to look for equivalency in off-shore markets:
Mercedes Benz 228.3
Volvo VDS-2, VDS-3
Global DHD-1

Also, good point on having an oil analysis done every so often - will definitely answer any concerns
- the Blackstone kits have been available on eBay
- the analysis is included in the purchase price

FYI: American Roger Penske of global racing fame owns Detroit Diesel, Allison, GM Turbohydromatic, VM Motori, and others

Mine still comes out pretty black after 5000 miles. GDE tune and Weeks elbow kit so I have absolutely 0 EGR.

Also, as a side not to what GMCTD said, Blackstone labs does test for fuel dilution but I was doing some reading over at the F150Ecoboost forum and they were saying that their test was an indirect measurement and was not very accurate. I am not sure if fuel dilution is a big issue with this engine, but I have been told to take blackstones figures with a grain of salt. The ecoboost will dilute 5W-30 to 5W-20 in a couple thousand miles. The theory is that ford changed their oil spec from 5W-20 in the early years of the ecoboost to 5W-30 because they knew this was happening.

hmm, that's an interesting idea of the belt breaking from broker rockers. I seriously doubt that that has happened unless the belt was well over the 100k miles (or tension was low, water pump or pulley bearings died). The belt I pulled with 154k miles on it the other day was cracked and looked terrible. I bet it would have snapped if a couple rockers would have collapsed. But, a newer belt on another CRD I have still looks glossy and new even after several rockers collapsed.

I am also still wondering what the best oil is :ALONE:

Oil still black, but getting better after 3 or 4 oil changes since GDE tune.

They offer several types of testing including fuel dilution
- a 'nuther is for metal particle contamination, including silica, aluminum, copper, magnesium, iron, zinc, etc - gives accurate indication of mechanical wear'n'tear per each oil change
- increased particle content = deteriorating oil, wrong brand, wrong API rating, necessity for increased filtration, etc
- you'd be surprised to see how differences in air filtration brands quickly effected testing results
- silica means dust = dirt, sand, etc thru air filter and especially thru Elephant Hose Modification\equiv

FYI: I use SHELL ROTELLA exclusively in all my Diesel engines : DCJx2, GM, KUBOTA, KAWASAKI (DAIHATSU), as it meets all\any global specs for Heavy Duty TurboDiesel service

Regarding oil. Jrsavoie said there is an amsoil on 10w30 or something like that, made for diesel and synthetic. The reason I'd get a 30 weight oil is because mainly the start viscosity, especially in winter.

I use 0w40 mainly due to having the lowest viscosity when cold from all oils that are good for this engine and easily accessible. I also don't see my oil over 180 degrees, unless I have more load to the engine than I normally have around the town where I drive most, so I benefit more from more flow on those temps.

Picking the right oil depends on how you use the jeep. It's like picking the right ammo for the gun. If you drive like me, mostly the only passenger, with maybe 1-200 lbs of extra luggage, Mobil 1 0w40 is not a bad choice, if you tow frequently, or drive very hilly roads for many miles, then Mobil 1 td truck 5w40 is good, or shell rotela, or a dedicated diesel synthetic that's a bit thicker and lasts high temperatures, as the turbo will get hotter, maybe 900-1000 deg is something normal under the conditions.

Of course, oil analysis is the best, I just wanted to show the color of the oil with gde tune, which proves less soot than normal diesel engine. Btw, nice "chart" flman!

olypopper · **Posted:** Sat Mar 14, 2015 2:07 am

I'll be running Rotella synthetic in 5w40(I think or maybe 5w30) as its what I run in my 6.7 cummins. Just going to get a drum of it! The reason I ask about oil analysis is for anyone that has been watching their oils before and after egr removal. I'd really like to hear soot numbers before and after. It must be huge.

Very good input, illustrating my point vis a vis "standard" MOBIL 1:
According to ExxonMobil, Mobil 1 0W40 is of the following quality:
•API CF
•VW 503 01
•SAAB
•OPEL Long Life Service Fill GM-LL-A-025
•OPEL Diesel Service Fill GM-LL-B-025
•FIAT 9.55535 - M2
•FIAT 9.55535 - N2
•FIAT 9.55535 - Z2d
API CF does not meet minimum rating of CG for TurboDiesel service
Intent was\is to bring up the difference to prevent useage of "standard" MOBIL 1 in the KJ CRD engine

I have used Amsoil, Mobil one and some brand that Id parts has shipped, not sure what is the best?

The Sasquatch El will help to clean it up more as well, considering the old el is full of gunk.

I have been using Mobil 1 Turbo Diesel Truck 5W-40 ever since Advance had that fire sale for like $6 a gallon. I bought like 22 gallons. Before that I was using Rotella T6 in the jeep, my motorcycle and my Subaru Legacy GT

I got Mobil 1 td truck for about 10 from autozone. You got a way better deal, I emptied the shelves from 5 autozone in the area, lol.
