Opinions on TurboMaster Device?

Fuel additives

As related in another thread - my switch to Amsoil 75w/140 in my LS differential effectively rendered my LS action useless - one wheel would spin merrily away on a slippery surface, while the other just sat there doing nothing - and that was with NO friction modifier added, which presumably would have only made the problem WORSE...



The fix has been to drain the Amsoil out, and replace with Valvoline 85/140 synthetic blend meeting API GL5/MT1 specs. A short trip and a half-dozen figure "8's" has restored my differential to nearly perfect LS operation - and I have little doubt a few more miles will completely do the job - if it gets TOO tight, I'll drain off a quart or so of the current lube, and replace it with a equal amount of the Amsoil I drained out - that should do it!



I suppose many folks really don't care, or NEED an operational LS differential in their applications - but I wonder how many others are driving around after switching to a full synthetic, and no longer have an operational LSD... :confused: ;) :D

Gary,

Do us all a favor, and whatever you do, please do not mix Amsoil with whatever you are running now.



As for you other question, be my guest and start a poll.
 
The American Axles in the 03's love Amsoil. I installed the Mag Hy-Tec cover and 8qts of Amsoil. The LS works great. I was as close to stuck as I could be in the back yard throwing all kinds of mud off both sets of rears. The owners manual also specs NO additive is required in this rearend. It was factory filled with synthetic from the factory as well.



I changed the fluid in my 01 H. O. to Amsoil at 40K and never had a problem with the LS in it. It would lay down two very pretty black strips all the way through fourth gear. It did this right up to the day I traded it with 81K miles... . CJ
 
I have had EXCELLENT results with Amsoil Series 2000 75W-140 (100% synthetic) gear oil in my Dana 70 LSD. It did however require a little additional friction modifier (2-3 ounces) so the LSD characteristics would work as desired... tuning it in effect.



Excellent product!



Prior to that I used Red Line 75W-140NS (also 100% synthetic) and it worked extremely well too.
 
I drained the factory fill in my '01 and put in Amsoil Series 2000 75W-140 with 4 oz. of friction modifier 2000 miles ago and have had great limited slip function from day one.

The 03's with a Mag Hy-Tech cover hold 8 quarts of lube???:--) :--) :--) I just drained and filled my rear diff this past weekend, and with my MagView cover, it only holds 5 quarts of Amsoil 75W-90.
 
I have absolutely NO idea why LSD clutch operation seems all over the map in these trucks - what works well for one guy doesn't for another - I really think the Amsoil is an EXCELLENT lube, and certainly would prefer to use in my differential, but I really DO occasionally need my LSD to function properly, so must make adjustments - hopefully I can find some other way or use for the Amsoil - I saved it just in case...
 
Saved Amsoil

It will make a great dust inhibitor for those rural roads out in Vacaville if you cut it with kerosene:)

A. Maybe it's DC's fine QC.

B. DC's specs are so wide you could throw a cat through them.

C. Awesome Cummins torque can't be held back.

D. All of the above.



:rolleyes:
 
Tom,

The Hy-Tec holds 8 qts. I had one on my PSD with a Dana 80 and it held 8 as well. It takes time to get all the old out. I jack one wheel up and let it drain for a while than the other side. 8 qts puts the fluid right at the top of the dipstick... . CJ
 
Question

HAve a question here from a newbie with a Dodge CTD. I have an ARB and Detroit in my Jeep so I LIKE my traction. My 2000 3500 has the limited slip in it. I am going to put the synthetics in the axles. What weight oil do I need and where and what is the modifier and where do I get it? I live in Kansas (the land of blahs) and tow less than 10K when I tow. Oh, I have the 60 in front and 80 in the rear. Thanks!!

I used Mobil 1 75w90 in my 2000 3500 4x4, found it on sale at the local auto zone. For what you are towing and the fact that it gets real cold in Kansas, I would recommend you stay away from the 75w140. I had to add a couple of bottles of the Mopar LS additive, get it at the local Dodge dealer. It is the best stuff. JMHO

Thanks, Pitbull, for your advice. Just off the top of your head, do you know the capacities of a D60 and 80? And any reason you use Mobil instead of Amsoil, just personal preference?? I haven't located an Amsoil dealer here in Lawrence, KS so far. Tha would be a reason for me. Robin
