Synthetic or Dino for Trutrac Break-in ????

themaildude · 03-22-2009, 07:14 AM

I'm finally gonna get the truetrac installed and was wondering what would be best for the break-in. Should I run dino and swap it at 500 miles to synthetic or run synthetic and swap it at 500 and continue using synthetic or fill with synthetic at install and change at 30k miles?

Good luck!!

I put dino in for about 1K miles, after that I drained and put in M1.

According to there website:
Lubrication
The TrueTrac differential is designed to operate in those lubricants recommended by the vehicle/axle manufacturer for conventional differentials.

I will do the same thing that Baseball fanz has recommended. Dino for breakin and the synthetic after that.

Yes Dino then synthetic for me just wondering when to change over 500 or 1000 miles.

I did dino then M1. Didn't notice alot of swarf (compared to the oem open diff break in).

I'm gonna say Dino, Old man Hooper didnt have anything good to say about synthetic in the Diff

Just thought I'd check in on this since I'm about to have TT installed... see what folks had to say now that they've had the experience with the swap. Is the final verdict dino for 1k miles then swap to synth???

Thanks!

I've had Synthetic in mine for 25K and all is well. I never put any dino oil in there. I just put syn in right when I added the TT and mine still looks like the day I bought it. I would go synthetic since that is what Nissan uses and TT recommends using what the manufacturer uses
