Amsoil or Redline?

[Donald]

Unfortunately, TBN retention (motor oil) is not great with Red Line, as evidenced by the many UOAs published on this forum. Other than that, their motor oil is great, and so is everything else they make.

TBN retention is a big deal unless you are looking at changing your oil every 3000 miles.

I have a 2008 Nissan Titan with 154k on her. I currently run a 2.94 Dana Rear ring and Pinion Gear straight from the factory. I will be making a change and having installed a Spicer Dana 3.69. I have always used Valvoline 75w140 but I am considering using either Amsoil Severe Gear or Redline.

I never go off road. 99% in town driving and very little interstate driving.

Thoughts, opinions , suggestion ,and on?

Why the change in a 15 year old truck with 154K miles?

Given that choice, Amsoil.

You can still use Gear Oil with Limited Slip additive. It will run slightly cooler

Come again?

In that case I don't think it would matter much what you use as long as it's in spec and changed out on schedule.

If I could justify the cost I would use Red Line, Amsoil is competitively priced in my area but still a premium. Is cost an issue?

Changed from a redline gear oil user to Amsoil. 75W-110 SVT in my 2005 Falcon 4-pinion LSD.

If you're not running it that hard I would just put the cheap stuff in it.
Or at most mobil1 since it seems to have the best antioxidant package.
That's what I use as I could go 5 to 10 years before I run up enough miles to need to change it.

DR1 Ask yourself, how many people do you know who wore out a differential?

probably the oldest most reliable device in the automotive drivetrain world is a differential..
You are overthinking it.
Just use whatever meets the specs that you want to use and worry about something else.
