Good for you. I went with the Extra S because that is the best and what subaru should use from what I read. Yes I could have put in another brand that I almost did but I just didn't want to take the chance using a cheaper oil. I got 5 quarts of Extra S for $75 to the door. I bought my 2009 impreza sport outback new and never change the diff or front tranny/diff in 29,000 miles. The fluid was in bad shape in both the rear diff and tranny. After changing to Extra S it was amazing how the car shifted into each gear.Amazing!!! It shifted better then the day I got the car new. I'll stick with the Extra S and will change at the next 30K.

I just wanted to bring all up to date. I got 5 quarts of Extra S gear oil from eBay for a $ 75 tothe door and finally had the time to change. I had no issues taking any of the plugs out. I found that I was a half quart low in the tranny. I was able to vacuum all the old BLACK oil from the front and back to make sure I got all the old stuff out. The magnet was pretty caked and cleans that off. All set with the change and want thank all who help me from this thread! Thank you! JAG

Hopefully I won't have that issue but you'll never know and that is very good thing to do. I'll jot that down. Thanks!!

THanks! I will order and change when the oil comes in. I will keep you posted! That makes sense to go with 4.2 liters = 4.5 quarts of oil. The manual says .08 quarts for the Diff and 3.7 quarts for the Tranny. Thanks for helping with this great info! JAG

I'm sold! I'm going to order the 5 qts of Extra-S and want to do it right. The car runs fantastic and just to have a piece of mind that's it's all good that I used the best of the best for my Subaru! Yes, I read some of the NASIOC threads. Yes, I'm going to order from Fredbeans.com. I did see it listed on some vendor site that said it was synthetic and that's why I asked the question because lots of people say not to use synthetic oil in a Subaru. thanks alot for you help!! JAG

Lucky Texan, Thanks! I didn't know that fluid is compromised!! Yes, I read nothing but good things about the Extra-S is very good for the $15 per qt. $87.00 to the door. Is the Extra-S synthetic oil? thanks JAG

Caboobaroo Thanks for taking the time to help! I change the oil every 5K. I already changed the air and cabin filter at 15k. I'll now do the rear diff and transmission oil and will do the brake fluid and spark plug change at 30K. One more question if you don't mind: The manual says to use the GL5 (75w - 90) fo both the rear diff and tranny. 0.8 US qt.for the rear diff and 3.7 US qt. for tranny. Do you think it would be OK to get the 5 quarts of the Valvoline/1 qt. 75W-90 high performance gear oil at Autozone for $6.99 or should I go with the more expensive Subaru (75w - 90). Extra S gear oil for $15 a quart? Does it matter? Thanks, JAG

Thanks for helping here. My Subaru only has 26K on it and shifts like new! I checked the Manual transmission oil and the level was below the Full line and thought I could top it off. There are no leaks but it's been 4 years that it has not been check. I should know better and check often. So what your saying is, not to just get a GL5 75w-90w from a local store and top off and mix with the old Oil but drain my current oil and get the correct amount of NEW GL5 75w-90w from the local auto store and refill and I'm good? Again, thanks for helping! JAG

Hi, I need to top off my 2009 Subaru Impreza transmission oil. I read the manual and it states under the "Recommend grade and viscosity" Each oil manufacturer has its own base oils and additives. "NEVER USE DIFFERENT BRANDS TOGETHER" It states to use GL5 75w - 90w. I'm guessing I have to go to my Subaru dealer and purchase the subaru GL5 grade oil. Is that correct? Or can I use a different brand and buy it locally and top of the oil? I don't want to mix and match. what do you recommend? thank you for your help!! JAG
