I posted this over on BITOG if anyone is interested in having a look:

6k miles?

 

Nah.. who cares?

 

That's all my tranny fluid lasted this time. So I changed the diff fluid too.

 

It looks like the contaminants have gone down progressively over time. The only exception is Boron which seems to have spiked up this last time.

 

Seems pretty straightforward. Now if we can get the Mobil 75-90 crowd to do a UOA...

I use LE and wouldn't use anything else.

 

I agree. I think some of the reduced wear rate is due to break-in. But then again, the oposite could be true for a differential. I just don't know.

BTW-Boron is an additive that the oil companies blend into their products to improve anti-wear and extreme pressure properties. Here is an article to explain further if you want to read it:

I'd like to see one of AMSOIL 75W-110. I think that would show good results too.

We already have a M1 UOA from X-Viper. It's included in the link that I provided above. But more would be better.

I always wondered why we don't see more UOA's of gear oil. Gear oils are the most suspect of all the lubrication products on the market IMO. The have very little to no oversight to meet API standards. And the API standards for GL5 are very loose at best. The weakest link in the drivetrain is the differential, yet we only see UOA's for the most bullett proof component of the drivetrain, the engine.

 

Try Amsoil MTG next time

 

I actually have. I used 60% AMS MTF and 40% MTG blend once and it was the worst decision I've ever made for my tranny. Maybe MTG or MTF by themselves is OK though.
