Why not RPM Delo 400
#341697 - 12/30/99 11:56 AM

I've only been around this site for about a month now but I've noticed that whenever the discussion turns to motor oil there are opinions on almost all brands except RPM Delo 400. I've been using Delo since I bought my truck used about 40K ago and it seems to do OK except it idles a little rough.

Since learning that the oil is so integral to the injector operation I've been wondering if changing to a different oil might smooth it out a little.

I would be interested in hearing if anyone out there has had any trouble with Delo 400 or has heard anything about the antifoaming capabilities.

Thanks in advance and HAPPY NEW YEAR Y'ALL.. !

I was using pennzoil 15-40hd (not happy with anything about it), and just switched to delo 400. It says right on the label that it is recommended for Navistar engines, and the Navistar web site says the same thing. I recently spoke to a Hydrotex rep.Hydrotex is a real high dollar synthetic, and he stated that in their "lab" tests,delo 400 was the only standard oil that he would run in anything that he did not put hydrotex in. I am going to try their atf soon. I have seen with my own eyes the difference this stuff makes on the trans temp,and inspected clutches and seals out of an E4OD {AKA:E4DOA)I think it is worth the $

Just to show support for Delo 400, I also have used it ever since the first oil change at 300 miles on my truck. My uncle used to own a Chevron Distributorship, and highly recommended it to me based on testing and performance. (I never bought any from him, so it wasn't a sales pitch. It is cheap at Costco anyway.) My friend's father also worked for Chevron in San Francisco, dealing mostly with diesel. He also highly recommended Delo, as well as using Chevron diesel due to its supposed higher purity (less contaminants and particulates).
In any case, I have not had any problems with it, and will continue to use it.

I have used Delo 400 in my truck since new. I now have 34K on the truck. I like it and would recommend it. I heard somewhere that FMC oil is Delo 400 only more expensive.

I work on a farm and we go through a couple hundred gallons a year of the delo 400, international, John Deere, and cummins, and they all purr. Because of a faulty oil pan pet**** on an L-10 Cummins (10 liters and 310 horses!) I have dropped 8 gallons of oil in a cornfield twice w/ it running till I noticed no oil pressure, w/ no ill effects. Except a long walk back to the shop, that is. So anyways, yes I believe in the delo 400.

I have used delo 400 since the first oil change at 3000 miles and I now have 78,000 and still going strong. I would like to see how delo holds up in a head to head comparison with rotella T. I will continue to use delo until there is some more information on a head to head comparison between the two.

I use the Dello 400 15W-40 and find it to be a good oil, no problems in my truck. About 47,000 miles now. I also have used the Dello in engine generator sets that were prime power and put many hours on them with no trouble from the oil. I think you can't go wrong with either of the oils, Rotella-T or the Dello 400. I think we are lucky to have the competition that produces such fine products and makes either one a good one.
Good luck with your truck.

Happy new year all. I have been in the maintenance end of the trucking industry for quite a few years. My current employer uses Mobil Delvac 1300. I just bought the truck listed below a couple months ago and put Shell Rotella in it when purchased. I did an oil change (this afternoon, in fact) and put in Delo 400 and a Fleetguard filter. I noticed less noise and smoother running immediately, enough to catch my attention. I was not looking for it. The power delivery seems smoother as well. The Rotella had 5,117 miles on it when it came out. After that and seeing this thread, I am now a believer in Delo 400.

Just one man's opinion.

Delo is a good oil!

With oil you have to do your own research because there is lots of opinion out there. There is also people with facts but each situation differs. You are better off figuring what your individual truck needs. This is best done by Oil Analysis Results and the way you use your truck.

For example you may be better using Rotella T a nice cheap oil and changing it every 2k if your truck performs extended periods of idling rather than using a synthetic Like Redline or Amsoil. Washing out the very expensive synthetic with diesel fuel makes for a bad relationship with your money. In this case a good cheap oil may suit your needs better.


I use Shell Rotella-T and have had excellent results from oil analysis. I have heard tremendous happiness from Delo users as well.

Since I am never satisfied with anything... I am going to try something this summer with all of my vehicles and Run Conoco Hydroclear Power D. I will try straight weights in the summer and then go with the multi-vis in the winter. Compare the multi and the straight weight and compare with the stuff I have been using. I will then make my decision as to what I should stay with.

Good Luck with your decision.

BTW. I have used Penzoil in My GAS machine and autos and it has shown the best oil analysis over Quaker and Castrol. Not by tremendous numbers but in every category by a few points.

I have been using Delo for about 6 months now and am quite impressed with it. Prior to that I was using Tech 2000 ( Quaker State )15-40 which is also a good oil ( for me ) I tried Rotella and my truck did not seem to run as smooth.

Why not jump on board on this. I used to be a Rotella fan tell I needed to change to oil and all I could get was the Delo. There was a difference in my truck. Smoother idle and better running. It also quited down a bit.

I now run Delo, but would not hesitate to run Rotella if I needed to. Both are good as far as I am concerned.

I use Delo 400 and truck idled somewhat rough, even with new oil. I shimmed the feul reg to 85 lbs @ and this really smoothed out the idle. Do a search on fuel reg shimming for details, it is really simple.

Well, here is my 2 cents worth. I have been using Delo400 since I bought the truck 4 years ago, and it runs great. I run this truck hard, and have had no problems except for the occasional glowplug relay. I can let the oil go 5000 miles plus and it doesnt seem to run any different (although I dont do this often). On a side note, I also run Delo400 15-40 in my 2000 explore with the single overhead cam V-6, my honda 4 wheeler, my lawnmower, and if my chainsaw had a crankcase, it too would probably have Delo in it.

Now hold it...This is about "RPM" Delo 400.
I've been looking at synthetics, and checking out Synthetic Delo I've noticed Chevron lists "RPM" H.D. motor oil, for "mixed fleet use": http://www.chevron.com/prodserv/nafl/trucking_prodspec_fs.htm
Specifically:http://library.cbest.chevron.com/lubes/compprd9.nsf/

[Now, it does not show Navistar in it's list of engine manufacturers requirements(Unlike Delo 400).
Soooooo....of the two, I personally would stick with the Delo 400.

I changed from Rotella to Delo 400 at 25000 miles. Now have 50000 miles. I see no difference between the two. Delo a little cheaper at Wal-Mart. My son is a rancher in MT. They have used Delo 400 for about 30 yrs on there place with no problems. Don't know how to rate oils if neither one gives you a problem. Changing at 3000 miles seems important. My truck starts to idle a little rough about 3000 miles. Really don't need a log to tell when you hit 3000 miles. Just listen to the idle.

This may sound strange but i have had poor idle quality ever since i owned my 96'psd for about 1 year I always ran rotella in it.Got it back from the dealer the other day, they put motorcraft oil in it after doing some engine work to it.I noticed right away my engine did not like motorcraft oil.This symptom only occured after a hiway run and coming to a stop it would idle terrible.Dealer techs. have not had any luck repairing the problem. I noticed some people in this forum use Delo 400 so i thought i would give it a try, guess what? My idle problem is gone. I am in no way saying Delo is a cure all but it sure helped my idle.By the way i always changed my oil and filter at 3,000 miles. Good luck

I cannot really comment on that oil since I have never used it. I have heard some good stuff on these boards about Delvac.

If I were you and was wondering I would do some oil analysis and see. Keep your current interval and sample at the next change. If you find that you are getting good wear metal numbers then stick with it unless you are a glutton for punishment like me and find it necessary to experiment. If you do find some problems then maybe seek some other company.

I just want to check the Conoco product for experimental reasons. The guy at Blackstone Labs told me it was going to be very tough to find an oil that would beat the wear numbers that the Rotella-T is producing in mine now. I run 3000 mile intervals with a Ford 1995 filter and am very happy with the results.

I figure that the Hydrocracked Conoco Power D would be just the ticket to reduce the wear slightly. It has a much lower pour point and has properties very similar to that of synthetic. Plus the price tag is better than 1/2 off the price of Mobil 1 synthetic. 10W30. Runs about 1.89 per quart plus shipping.

I intend on running the same 3000 mile drains and using the same filter. I am looking into finding a better filter because I have never been very fond of the sheet metal bypass spring found in the FL-1995

The Delo 400 was used by the local LaFarge gravel pit in my area and it stands up the best. Now they have changed to Petro Canada oil and the mechanics don't like it. The Delo 400 10W and 30W oils they use to use would last longer and perform better.
I know ESSO makes a good oil thats all we used at the local highways dept in all the equipment and it was ESSO LUBE 15W40.
I'am running 15W40 Penzoil longlife and I seem tobe pleased with it.

The Synthetic crap can stay on the shelf in the store along with the Quakerstate and the other cheapo brands.

Thanks
