Hi all,
Is Amsoil SVG 75w90 GL5 gear oil suitable for subaru impreza's differential and manual transmission?

Amsoil SVG on Subaru

Search around a bit. People use SVG and like it. It's not my top Amsoil recommendation for shifting, based only on the fact that it contains LS additives. I've had no reported problems, however. And in Singapore maybe you can't get this:Amsoil FGR GL-5 75W-90, my recommendation.
It's certainly good for the differential. I've used it for years in my Subaruae (is that plural for Subaru? B~))
Running the Severe Gear 75W140 in my three soobs front and rear diffs, 2000 Outback, 1996 Legacy, and 1994 Legacy (these are all auto trans).
Soobs can be a little picky about gear oils for the manual trans for smooth shifting. I have seen in the past on soob boards issues with mobil1 gear oil eating up some parts in soob manual trans (not diffs) something about the high sulfur.

The high sulfur becomes an issue in manual gearboxes, because it can react with, and corrode brass and bronze. Since differentials usually don't contain brass or bronze, it doesn't cause trouble.
The lower sulfur limits in the API GL4 specification are one reason why GL4 oil is recommended in manual transmissions.
All this in mind, I'd sure like to see those Boron based additives by Chevron combined with fully synthetic basestocks. This might solve a few problems.

Hi, I am currently driving a 1.6 impreza. You are right, the FGR GL5 is not avaliable here. Seems that only SVG and GL4 MTG is avaliable. Look like SVG is the only option for me if I want to use amsoil.

Does it mean that SVG is not recommended for the manual gearboxes? Actually, I intended to use SVG for my differential and manual gearbox since Subaru's manual handbook specify the same rating for the both components.

SVG will do fine and not corrode brass or any other metals in your manual gearbox.

Noted. Thanks for the clarification.

Good thing Suby requires a GL-5 75w-90 gear oil in the 5mt otherwise there may be a problem. I run the SVG in my 5mt and rear diff of my Saab 92x without a problem. The 92x is a WRX in different sheet metal.
