You can use ATF in a BMW differential? I thought you had to have a GL-5 gear oil!
 
2002 Subaru WRX Wagon Auto @ 143693 miles

Out: Unknown 75w-90 - Approximately 30k on interval. Fluid was still very clear and the magnet didn't have very many filings.

In: Valvoline Synthetic 75w-90
Also put in new drain and fill plugs because the old ones were rusting and beginning to strip.
 
2010 Mitsubishi Lancer Ralliart Sportback
Transfer case and differential:

Out: Valvoline conventional 80W90
In: Valvoline conventional 80w90
Mileage on car: ~14500
Miles on oil~ 5000

I bought 1 gallon for $25 at AutoZone and this is my second fluid change from that 1 gallon container.

I thought there would be more stuff clinging to the magnetic drain plug, but there wasn't. I will leave this gear oil in for a long time.

2003 Ford F350 SD. Drained the factory lube at 96000 miles, and refilled with Chevron 85w140 and 4 ounces of Redline Limited Slip additive. While I know it is not a true 75w140 like Ford calls for, I'm certain it will do just fine. I also installed a 2010 factory aluminum cover.

I really like it. First diff cover I ever had that has a dipstick. Makes sampling and checking level so much easier. I am also digging the extra capacity.
 
This month I did 2 diff services

Amsoil 75-90 Severe Gear in:

2000 Silverado 5.3 w/ 42k miles orig fluid

2003 Tahoe 5.3 w/ 114k miles orig fluid

both have 3.42 w/ G80 Eaton Locker
 
2011 Toyota 4Runner, 24000 miles, rear diff.

Per severe service schedule, this should have been done at 20,000 miles. Oops.

Out: Toyota synthetic whatever. It did not smell like conventional gear oil.

In: Advance Auto full synthetic 75W90 GL-5, it was all I could find that was full synthetic that day. The bottles had a 'P' on the bottom, who makes that? Pennzoil?

I'll do the transfer case and front diff at 30k, and will probably use Amsoil then.
 
First BITOG post!!

2002 Subaru WRX, 91,500 Mi., rear diff

bought it used so figured better sooner than later...was I right! Probably the factory fill and "fluid" was like gray primer paint in color and consistency. Still smelled of diff fluid, but muted a bit. Luckily, very little shavings on the magnet.

In: valvoline synpower 75W-90 GL-5

I'll probably do it again in 1000 miles to flush the gray crud out and fill with same again.
