Engine/Transmission (1998.5 - 2002) Alright Amsoil Guys-Beat This

[amsoilman]

Gary,

Sorry, I do not have a recent analysis of Delo 400 15W-40. The only real way to do it is to send in a "new" Delo 400 15W-40 oil for analysis.



Most oil analysis labs have this sort of data on hand, so you could contact one of them and see if they would provide you with a copy.

Wanna see this go even further south... . tell us about your K&N air filter.



p. s. I'm happy for your results.

 

[CFast]

very seldom do you see an engine overhauled for poor oil maintaince(sp). It's usually poor water maint, causing cavitation. Mechanical failure and poor air filter maint are other causes for O/H. I've pulled mains and rods bearings on some engines, with horrilbe looking oil, that look good. Unless you get fuel in the oil, that's a little different though. If regualar delo 400 can make the big trucks run 1million miles then it's good enough for me. JMHO.

 

[Spooled-up]

I've always heard that since our engines don't have cylinder liners that they aren't subject to the problems of cavitation. Or am I thinking of something else?

 

[RustyJC]

No, the B-series Cummins is a parent bore engine that does not use wet liners. Therefore, it does not require DCA to prevent liner cavitation as did the 7. 3 Powerstroke and C-series and larger Cummins.

O. K guys I am moving his thread to the engine trans forum but promice me it stays clean

 

[Jar Head]

As an addendum, I noticed that an oil sweep that I had on the backside of tho oil pan is now dry since I switched back to dino.

 

[Ajwalls]

Jar head- Keep doing what you are doing, test, test, test, and don't forget the filters. You may even have an abnomal reading once or so, just keep looking at your progress of getting the lead and copper out of your tests. By the way I am a Amsoil user myself, and I am doing the same thing you are doing testing etc. Please let us know the result of your next lab test.

OK I know I live out in the sticks, but I have never heard of Delo 400. I have been using Rotella 15w-40 until last fall when I switched to Rotella T 5w-40 for the cold winter. Does switching from conventional oil to synthetic or vice versa hurt anything?

 

[amsoilman]

Aaron_A,

It won't hurt anything, but I don't like switching any brands of oils, either petrolium or synthetic. I choose one, and stay with it.

Those numbers look good, but you can't compare that report with Amsoil, or any other oil. Oil, whether dino, or synthetic, have different additives within the oil. As Wayne stated earlier, no two vehicles with the same engine, will have the same numbers. Stay with the same oil and keep doing your analysis program.



I use the Amsoil Series 3000 5w-30 in my truck. I use this oil because I want the benefits of a synthetic, and with changing the filters and maintaining an oil analysis record I can lessen the waste of 11-12qts of oil each change. So far, I have almost 60,000 miles on this oil. I change the full-flow filter every 12,000 miles, and the By-Pass every other filter change, adding oil when needed. After initial change, 4 full-flow filters, 2 By-Pass filters, and a little over 3 gallons of oil used.



Every report comes back "no corrective action required, oil is suitable for continued use. " Of course when I want to check my reports I can't find them.

"but you can't compare that report with Amsoil, or any other oil. Oil, whether dino, or synthetic, have different additives within the oil. "



I don't know of any that add significant Iron, aluminum, chrome, copper, lead or other wear metals - and those are the ones *I* pay pretty close attention to - and with so few diesel-rated oils available, it's pretty easy to compare one guys readings with another using the same brand... Extremely low wear metal readings are a GOOD thing regardless of the oil being used - and that is the point of this thread...

Trends within a vehicle not between .....

Gary! I think what Wayne and others are saying is each engine develops its on trends. Some engines start out with Fe at 25+ after 6K miles no matter the oil used. Others never see over 12ppm.



I have grabbed samples every 6K for the the last 200K+ miles on my truck and I can see trends for my engine. But I really don't compare them with anyone else as too many varibles exist that can easily explain why truck X has much lower wear metals.



Someones oil analysis info is always neat to look at and cummlatively it starts to give a picture that might be usefull. As long as all trucks operate the same, in the same climate, idle the same amount, etc etc.



IMHO... . Unless one runs extend drains, or needs that extra protection when running extreme operating conditions (drag racing, sled pulling), todays options for Group III "synthetics" covers most of the basis. I really believe a 5W oil is need when operating in temps below -15. Three years ago that meant Amsoil or Mobil (Group 1V). Today we have several options.



If you want to compare oil analysis between oil brands don't even include Group IV unless the mileage on both oils is beyond 15K. That is were synthetics will start to justify there extra cost.

hey put some REAL MILES on that truck and leave the oil in there for 80. 000 then u got some thing amsoil rules

This is a little off the subject of this thread but... you mention liner cavitation. Is this the same as what we always called electrolysis? (sp?)

 

[Texas Diesel]

Great test results, nothing could beat them. Thanks for posting. These engines are way overbuilt and do just fine on Dino oil.



I agree, no reason to pay for TBN when following Cummins recommended service intervals.



All of the million mile + engines have used Dino oil and OEM filters, no exceptions. One MUST conclude that dino oil +OEM filters + following Cummins service procedures = million(s) of happy miles, how can you improve on that? Your Ram will be on the cover some day with 1. 2 million miles the way you are taking care of it.



On the otherhand, if a person wants to buy a superior oil [compared to dino] no harm done. I run Royal Purple in my 01 with 10,000 mile intervals, my wife insists I change her oil at 5,000 mile intervals, Delo 15W-40 and OEM filters. We're both quite happy amd waiting to see which one hits 1,000,000 miles first.

 

[Gary - K7GLD]

At the rate I'm going to date, I'll be about 115 years old when my truck reaches a million miles...



We'll all probably be outta fossil fuel, and running on roller skates by then...

 

[bgilbert]

How do I go about getting a oil analysis, how much does it cost? Thanks Bill

Call them and ask for a sample container. TDR members get $1. 50 off the price if you tell them you are TDR. They keep your history and show trends. Good people

As a newbie, I found the discource in this thread very helpful. Thanks all for the input.
