How To: Reduction Gear Oil Change

[knightmb]

I'll bet there is nothing wrong with that fluid

I am curious myself if it has anything about it that would be "bad" for the gears, but I am not a expert in fluid dynamics, so it would be best to post up the results here (or the elsewhere should it be a better area) for someone that does know about it to tell us if it's good or bad or neither.

How about we let Blackstone labs decide?
I'm thinking 70,000 is probably close to being "bad". I doubt they will say "oh you could have left that in for another 70,000 miles.
And I bet 20,000 to 25,000 miles will be fine.

I've never used them, so I didn't know if they just give you technical stats or if they give you a cool summary like "oh this is bad, this is tearing up your gears", etc.

I've used Blackstone Labs for motor oil test. They'll give you an English description of the results. Often, it comes down to, "This oil change interval try going an additional 1,000 miles." There are statistics for the test measures that will show universal values and your past values.

The kit just arrived in the mail, time to send it out!

I used them for a few years. Never anything particularly interesting in the results which is a good thing of course. I know the tests can alert you to problems before they become big problems, but in the end it was too much hassle for me. Modern ICE engine oil is fantastic and the question of "which oil" is more for entertainment than practicality. Change it regularly and oil analysis is kind of a waste of time, imho.

I think the service is probably a lot more useful for fleet or industrial applications trying to optimize maintenance intervals and avoid downtime. Or perhaps individuals who really push their equipment (tuners, racers, hot-rodders). For me, cars usually last a long time anyway so I saw little marginal value.

That being said I am curious as to how well this "lifetime fluid" is doing at 67K

When I had my Titan, I used Blackstone. They kept increasing my interval, until I went too far one time (my fault). Otherwise, nothing interesting. I haven't tested any of the oil coming out of my F-350.

I never sent them an oil sample from a transmission, gear box, differential, ect. Always from an ICE.

I bet they haven't seen many of those.
So the oil is about done after 50,000 to 60,000
miles.
PM me your paypal and I'll send you $20.
Then I'll do mine around 25,000 miles and I'm sure it will be good.
I'm almost to 20,000 now, I'll be at 25,000 early next year.
