Default Two OEM Tranny Oils--One Confused Subie Owner.

Went into the dealer last night to do some investigating. I wanted to find out the difference between the two Transmission Oils Subaru markets.

One is called G-O Extra and is a 75W80 Fluid. The part number for this is K0323F0091.

The other and apparently more popular fluid is the G-O Extra S, and is a 75/90 weight. Part number is K0322AA093.

Both are GL-5's (what do these groups refer to anyway?). Both come in 5 Gallon drums. Ive been getting mixed responses about one being synthetic, another conventional, etc. It's kinda driving me nuts because no one can give me a straight answer and no one seems able to recommend one over the other for my Legacy 5-spd. Im sure either will work just fine but I wanted to see if anyone would be able to clear things up for me.

Honestly this is the wrong section. Head over to the transmission one and people will be more versed on the topic.

I run neither of those oils so can not be much help.

It's the Extra S that you want.

You want Extra S it is what the books calls for, however you can use any 75w90 you choose. I switched from Extra-S (ran it for 60K miles) to SuperTech 75w90. Wow works equally as well in cold and hot, no notchy shifts in the cold just like Extra s and it cost about a 1/3 to do the gearbox and rear diff
