Amsoil Series 2000 Gear Oil

[DPKetchum]

QUESTION. What was grinding?Seems if any grinding damage was being done?

 

[roperteacher]

you know, I am not sure of the exact component that was grinding, it just was! When I had it changed out they used the suck out method, not taking the cover off. The AMSOIL that was getting sucked out looked OK, but then again it was only 3,000 miles old. I didn't want to see what was inside. . LOLOLOL Since it only did it when turning corners and pulling, and had only done it for a short time, I figured it was OK. When I called my dealer he said " When it breaks, we'll fix it" We can't slap on new parts just cause". . SO thats what I am doing. I have 85,000 more miles of warranty. If she quits, they fix it. . But since putting in the valvoline, PERFECT... . not grinding what so ever. I used to have a "Howl" between 65-70 MPH... now that quit too! Very nice!

Roper,if I was you I would take that cover off and inspect it,the sucking method SUCKS to be blunt,I would think you should get out all the metal shavings that was produced by the grinding.

Also what about the 75W 140,I had read somewhere that it took care of the grinding and that DC was going to start using it in the AAM axles?

I used the Amsoil 2k to ELIMINATE the same problem in my Vette. No matter how many tubes of LS additive I used, the rear would shudder in turns until I switched to Amsoil 2K and NO LS additive.

Did you have the "howl" before the Amsoil 2K, that is with the factory gear oil?

 

[roperteacher]

Yes, the howl has been there ( Was there) since new. It just moved fom 55-60MPH to 65-70 PMH after the rebuild. Now I have NO HOWL whatso ever. THe AMSOIL fixed that part! I'll pull the cover off the next time I change out the gear lube. Right now it is running perfect, no noises and I am inclined to leave it that way. If something happens, DC can fix it! I probably will go to the 75-140 next time. I haven't heard any news about DC officially using it. You would think they would send a postcard or something! Right now, I am sticking to the factory specs in my owners manual...

 

[Gauthier]

roperteacher you have Valvoline Syn 75-90 in now correct? The Valvoline Syn 75-90 fixed the howl?

 

[Rosco]

Has anyone called Amsoil to inquire?They have a Tech help line.

Yes, I did. The funny thing is that the tech fellow I spoke with told me just the opposite of what you guys are saying. He said the Amsoil series 2000 does NOT have a friction modifier in it and suggested I add some to cure my problem. However I know better, so that is why I am going to try a different oil in the rear at the next change.

 

[roperteacher]

Actually, NO, the Valvoline did NOT quiet the rear howl, the AMSOIL did. My truck had been to the dealer several times for the howl, they verified it as "Normal" of course The AMSOIL fixed er right up. About 100 miles after it was in, Poof, no howl. Now that I have switched to Valvoline, STILL NO HOWL, and I wnt on a 700 Mi Round trip this weekend pulling 8,000 Lbs. Perfect!!! The only time it would grind with AMSOIL is when it was LOADED and around sharp corners at an incline. I figure the 3,000 miles the AMSOIL was in there, it maybe ground 4-5x, and sometimes it wasn't hardly that bad. So I didn't bother to take off the diff cover to change out the fluid. THe "Sucker" method worked fine. It probably didn't get all the junk out, and I bet I still have some AMSOIL mixed in there. Maybe thats why I don't have my howl???LOLOLOLOLOLO Whatever is mixed in there now is working great!

It"s wired, some times you can eliminate the chatter by just adding more FM,I also believe that their is more additives in the TGR, I just don"t think it worth the extra cost. Unless you go 50k or more before service.

 

[Rockcrawler]

FWIW- I just made the switch, at 50k. Yea, maybe should have done it sooner but I rack up the highway miles fast and usuallly only tow 8k or so.



A "friend of friend" does a lot of hotshot stuff, has a pyro in his rear diff, saw a sig. temp drop with the amsoil- was enough to convince me, sorry, don't remember the before and after temps. Went with a PML cover too.

I put the Amsoil series 2000 75w90 in my front and rear diffs at 15k miles. I have 27k miles now and have zero noises, howls, or issues. In a few thousand miles I'll have a much better idea of how it's doing with the cover off.

Filled

In changing to the Mag-Hytec and Amsoil Series 2000 75W-90, I jacked up each wheel and let 'em drain for about 1/2 hour per side, then wiped out the bottom as much as I could. When I filled it, I brought it right up to the upper of the two marks, figuring replacing what had drained out from the axle tubes would likely bring it down a bit. Today I drove it around for 10 or 15 miles, including a few figure 8's in a parking lot. Now the dipstick (I love having that) shows exactly midway between the HI and the LO marks. Interestingly, the dipstick's magnet had gathered a little ring of powder, presumable washed from the interior of the diff. I guess I should check and clean it periodically. Hopefully after a few 'washes' it will stop showing up...

Did you notice any grinding??

 

[GerryDrake]

No grinding

Didn't notice any grinding or noise whatsoever, but it wasn't much of a test.



The main stop was at the local Dodge dealer to make an appointment to have 4 or five minor things checked. Haven't been looking forward to this as though I live in the Seattle area, I bought it in NC, so don't know what the dealer's attitude will be. The service advisor who set up the appointment seemed VERY pleasant to my situation of not having 'been able' to buy it from them.



Tuesday they will have it for a day or two for:



1. transmission or xfer case leak (minor seepage)

2. Power steering howl when going slow, only after it is well warmed up.

3. See if my alternator bracket is intact (no problems, but take a look)

4. See if the block heater is in tight, figure out the minor coolant loss and residue by the block heater.

5. The oil smell through the vents after an oil change... (said, Gee, we have never heard of that... . I told them of the TSB on older models etc. )



We'll see what they say...
