DELO 400 LE synthetic 5w-40

Since I switched about a week ago from the T6, the Jeep starts much better in the cold and does "seem" to run smoother. I have a sample bottle from Black Stone ready for an oil analysis on the next change but it will probably be a while since the CRD doesn't get driven during the work week.

2300 miles on it.

The engine sounds quieter and the oil dipstick indicates that the oil stays cleaner longer.

i have a couple of unopened gallon jugs of the 5w-40, 1 new bosch oil filter and a bollte of zinc that i'm not going to use as i traded in my jeep this week. If anyone is interested shoot me an offer for it. Just trying to recover some money spent. Thanks, Mike. Shipping would be from MN.

A motor always sounds quieter right after you change the oil, so don't put too much weight in the "it sounds better" test...plus there is alway the placebo effect - I changed something so it must be better.

Rotella T has proven time and time again to be a phenomenal oil - just look at any UOA posted on various enthusiast forums. Mobil 1 TDT too. Delo may be on par with these oils, but its certainly not a magic elixer.

While I agree the T6 is a great oil, the stuff gets pretty thick in the cold (Experienced both in my CRD and Subaru), I think the Jeep starts much, much, better in the cold with the Delo. That being said I will probably Switch back to T6 once the weather warms up.

Almost 4500 miles and it still sounds quieter and starts smoother. BlackStone will tell me soon.

The thing about opinions is every one has one.....anyways as explained earlier shell rotella is a great oil I used it for a short duration 1750 KM or 1100 miles as I wanted to get a UAO in order to determine everything is working good with New to me jeep and if it is worth my while to sink more money into it and the order of issues like what gets done first . This being winter I realized it was more noisy and had cold start issues with rotella and with Delo it started quit and once on operating temp it cruised, (again my opinion) ..."quieter than a church mouse"....( ok I borrowed this phrase but I liked it).
So you are free to take your view on this but in the war of oils I was impressed by Amsoil and turned off by its amway style marketing wanted to try Mobil TDT as peeps have good UAO reports here but the fact that they put 4Q for 28 bucks turned me away Rotella to their credit 5Q is 20 bucks and next thing was Dello 4Q for 20 bucks and I am glad I used it just listening to turbo spool makes it worth it .
By the way jury is still out as I do not have UAO report on this oil and report on Rotella came all OK but I did not like the way my Jeep drove on it.thanks

Don't know if its the oil, that Bosch still has my Rotella clean after 2200 mi

I still have not sent my UOA for Rotella T6 or M1 0w40 due to some recent health troubles. It may be a bit before I am able to get to that. A UOA of the Delo would be awesome. Anyone have any UOA's on the RT6 or M1 0w40, M1 TDT 5w40, or Amsoil Euro 5w40?

As stated I have a UAO of RT 6 didn't have the time to put it online it is Squeaky clean as it just had 1100 miles on it , zinc levels in oil are impressive the report tells me everything good about the oil but my ears and jeep on cold starts tell otherwise.

I've got a 9500 mile sample of RT6 at Blackstone right now. Just waiting for the results. Until then you can peruse viewtopic.php?t=4582

I don't see why it starts better with the Delo. Here are links to Delo LE and RT6 spec sheets, showing they have identical pour points of -42C.

The -30C cranking viscosity is actually lower in the RT6 than the Delo. 6000mPas vs 6250mPas (62.5 Poise) for Delo.

Just going by those numbers I wouldn't think there would be a detectable difference in cold start ability.

As stated previously it is the cold start and the Highway cruising once it reaches operating temp. Second part is more like day and night all i hear is the turbo whistle and engine is super quiet. I wish i could back it up with any numbers but so far nothing anyways here is my T6 report on 1100 miles ie 1750 KMs.

Just and FYI

I was looking at some DELO 400 at costco, but it didn't say synthetic it was ISOSYN, and it was 15w40 but for still for diesels... I almost grabbed it before I looked closer!

I posted mine on TDT. I now have amsoil full saps and should post that by april.

They also make a Dino version which is cheaper than others but what is being referred here is fully synthetic and has LE and 5W40 tags on.

Yeah I had to look it up when I got home. I was at costco and I remembered someone saying they saw it there, so I found a box of DELO 400 and grabbed it assuming it was the synthetic version. I didn't really read it because I assumed it was right... My complete mistake!

Apologize for those that have a cow over me reviving a slightly dead thread. I have been using the Delo 400 LE 5w40 synthetic in my CRD for a while. I also use it in my Detroit Series 60 semi truck engine. The later, I have taken it to over 25,000 miles on the oil and it still has a lot of life left on it. TBN had only dropped to 7 and the wear numbers were great. Haven't done a UOA on the CRD to see the results. Delo makes some first class products. I have used various products of theirs for quite a few years. I am even using their nitrite free ELC coolant in the CRD. Same stuff I use in the Detroit and the previous Cummins ISX I owned. It is a top notch product for really protecting against liner cavitation on wet sleeves and provides superior water pump lubrication. Good enough for my big diesels, good enough for my CRD. I am really surprised that the Delo stuff hasn't made a bigger impact in the small diesel arena.

I have been picking up cases of the 5w40 syn from my local Wally World also. Been $19.98 since early last fall. Just ordered a few more cases last week. Needed to beef up my supply. Now at 34 gallons on hand. Cheaper this way than trying to get it by the drum from my local distributor. My local Delo oil distributor is wanting $27 a gallon for the same stuff! Ripoff artist.

Kind of ironic that this thread just got revived. I just changed my oil today and finally got to put in the Delo 5w-40 I bought awhile back. I used the Mobil1 M-301 filter again (what I usually use). I had tried the Bosch 3500 Plus last time but I went with the M1 M-301 this time. The filter doesn't make a difference as far as oil color goes for me. No matter what filter I use the oil is ink black as soon as I start it up after filling and shutting it down to check the oil level. I will be sending my oil off to Blackstone tomorrow and I'll post the results when I get it back.
