The switch synthetics

[GMocanu]

I have synthetic oils (all Amsoil) coming during the next week for the engine, front and rear axles, transfer case and the NV5600. I also have a single by-pass system coming. My truck has almost 43,000 and I have no idea what's been used in it before I bought it. I've had the valve cover off to change the injectors and it was very clean. I intend on using oil analysis and extended drain. Actually I never intend on changing the oil unless the analysis says to. I will change the filters regularly.



My question is do I just need to drain everything real good and put in the new oils or do I have to flush out the old oils? I'm thinking that because the truck doesn't have many miles on it and because it is clean inside the engine that there is no need to flush it. I'd actually prefer not to flush it but I will if it is necessary.

Amzoil recommends using a can of flush before switching. I have not because I have been able to buy new and make the switch after 10,000 miles. If it were me in your shoes I would run the synthetic oil in the motor and drain at the recommended interval. After that I would do what the analysis says. As far as the other oils I would not worry about it. Get the most you can out and refill.

I would just get it well warmed up and open all the drains. Take the covers off the diffs and you can wipe out the bottom of the housings, take the PTO covers off the transmission and wipe it out. On the engine if the present oil is clean and you found no deposits when you had the valve cover off I would probably not flush it. You could fill it with petroleum oil one more time and run it a couple hundred miles and then refill with the syn.

I had the oil changed when I bought it in April and it has 3500 miles on it.

If you don't want to use the flush go ahead and put the oil in with new filters,run it for several hundred miles and change either the oil/filters again or just the filters and then have your oil analysis done and go from there.

Is this because you expect the Amsoil to find some deposits somewhere in the engine and clean them up? If so, what's the procedure for using the Amsoil engine flush?

 

[lschultz]

I think(don't have a can with me at work)1 can is good for 6qts. of oil so you would use 2 cans of flush on a engine that holds 12 qts. of oil. If I remember right you put on a new filter,put the flush in and run it at a fast idle for so many minutes. The directions are on the can. Then drain your oil out,put on a new filter(fill it with oil)and then put the rest in the engine and your ready to go. Amsoilman will probably be on here to add some to it. If there are any deposits left in the engine the synthetic oil clean it out. But if you only have 43000 that engine is just starting to break in and if its clean like you said it was whoever had it must of did the oil changes when they were due.

What did Amsoil send you to put in the NV5600??? If it is Series 3000 5W-30 HDD, be adviced that you will void the transmission warrantee if ANY transmission lubrication related failures occur. Not throwing any bombs here, just passing along the research I did. I was going to do this myself until I spoke with the New Venture factory rep and Diamler Chrysler. This oil may be great stuff for all I know but if a lube related failure occurs, you are your own warranty station. DC said they will do oil analysis and if it is not Texaco MTX 1874 or Mopar Part # 4761526, it is your baby. This is as per Ken Koliba at New Venture. The Series 2000 75W-90 is great stuff! Use it in my John Deere mower gearbox too!

Thank you for your advice but I have no warranty to worry about voiding.

I work in the lubricants industry as a manufacturer.....

I would like a copy of this in writing from NV or DC.

If you do have this in writing, DC must supply the Texaco / Mopar fluid "free of charge" for the life of the warranty as the fluid jsut became part of the warranty. This would otherwise violate the Magnuson -Moss Fair Trade Act. A manufacturer can not void a warranty just because of the use of / or addition of, an aftermarket product, in this case, an oil.



Now, if the failure was due to the use of a "non-spec" part (IE, an engine oil rather than a specified manual transmission lube) and the non spec part was the cause of the failure, then I agree with Ken Koliba of NV.



DC / NV can not void your warranty for the use of Amsoil if you develop a crack in a tail shaft housing due to a casting flaw for example. The use of a different oil the OE that meets the OE specs CAN NOT automatically void your 7/70 transmission warranty.



I would think that if the lubricant used was recommended by the lubricant manufacturer specfically for that application, and it proves to have been the cause of the failure, as a US manufacturer, they have to carry 'liability insurance' or are 'self-insured' against such claims and should make good on the trans.

Redram, reality dictates that DC and New Venture have alot more money and lawyers than you or I will ever dream of. If what you said was true, then DC should supply us with oil filters as well since they issued TSB 09-004-01 pertaining to specified and approved oil filters compatible with warranty. Don't hold your breath. The Magnusson-Moss Act won't do squat for you. If you don't believe me, just go to your local DC deal and tell them that you just put Amsoil in your NV5600 and they will tell you what I just told you. Good luck takin' 'em to court.

If Amsoil is recommending their motor oil for the NV5600, and you plan on using it, I would strongly recommend that you get in writing that it is an acceptable substitute, and that they will warranty the transmission in the case of a lubrication related failure. I really doubt that the staff at Amsoil even has the technical specs on the MS-9224 lube to know if their product meets the spec. Don't get me wrong about Amsoil, I am using it everywhere in my truck EXCEPT the NV5600. For all the other gear boxes, they met the spec from Dodge so I used it.



Here's a page from my website on what I used in the NV5600.

This is what my 2003 repair manual says regarding the NV-5600 manual transmission fluid.



"NOTE: DaimlerChrysler recommends using Mopar

lubricants or Lubricants of equal quality "



If previously there was a placard on the side of the transmission that warned of using only a certain named brand product, then something must have changed in the 2003 model, as there was no such placard on my transmission.



I'm using the 5W-30 series 3000, which Amsoil recommends.
