This was run between 2,500 and 22,400 miles in my Forester's 5-speed manual transmission. Viscosity was flagged. This was a Wix prepaid analysis kit. There was a bit of black sludge on the magnetic plug, but nothing that I haven't seen before. I didn't see anything shiny on the plug or in the oil.

I'm concerned about the level of iron, and the viscosity is obviously low. Thoughts?

I refilled it with the same, but maybe I should switch to something else.

As close as Valvoline looks to be what Subaru transaxles call for, my Impreza did not like it. Shifts into 1st and reverse from a stop were always crunchy. I finally spent some money on genuine Subaru Extra S and it cured the problem.

How about that! Last time I looked, it was available only in 5-gallon buckets. I may go that route. Red Line 75w-90 NS is my other thought.

Ah. I see now. That's rebottled by a dealer.

Wow, it sheared and dropped two grades to 80. In only 20k. From 15.5cSt@100C according to the PDS its down to 10.9cSt. Just under an 85.
0/10 would not use. Would use the 80W90 instead or switch to synthetic 75W90 if you need low temperature performance.

Trans is still young and breaking in. Shearing is excessive but usually normal in a manual.

Try another gear oil. Idemitsu, Eneos, Redline, Motul, Torco... have nonLSD 75w90 gear oils.

I would not worry about the Fe; this is break-in residual. You dumped the OEM fluid in 2.5k miles, and this is only the second load.

Improvement should come on the next few OCIs.

I'd say overall, the Valvoline didn't do a bad job at all, despite the Vis loss. The Fe is expected in such a young manual tranny unit, and will never be as "low" as engine UOAs.

Conventionals vs. Synthetics isn't about which is "better"; it's about which lasts longer, while assuring safe operation, in relation to cost. Any product can be over or under utilized. The same applies to filters.
Make an informed decision; first consider your operating conditions, next determine your maintenance plan, and then pick your lube and filter. Don't do it the other way around ...

Thanks for the feedback. I'm amazed at how much the viscosity dropped. Pablo hooked me up with enough Amsoil Severe Gear 75w-110 for the transaxle and rear differential. I'll run that for 20k miles and get another analysis as long as the shifting remains reasonable and I still have the car.
