Default Subaru Extra S in Cold Weather

I would like to know people's opinion of how the Subaru Extra S transmission fluid performs in cold weather (<20 deg F). What kind of problems have you experienced in the winter using this fluid?

This trans fluid is recommended in one of the stickies related to trans fluid and after searching it seems like people generally have good opinions about it. But I have not seen many people talk about how it performs in the cold. I found one or two posts about because the fluid is not synthetic that it won't perform as well as a full synthetic in the cold but I think that was just one person stating that. I would like to hear a few more people's opinion on it before I make the switchover. I have Redline in there now and had some problems shifting when the trans was cold. I don't want to go through the winter again with these problems.

I had redline and extra s. Their both good. Redline one I felt was a bitch to change your first 2-3 gears in cold but once it warmed up(1-2miles) it was fine. Extra S is a lot better. Shifts no problem and does better in cold. Just my 2 cents though

Extra-S is good stuff and comes as factory fill. It should be fine for all conditions.

What are the drawbacks of the Extra S being non-synthetic?

I would also still like to hear others opinions of this fluid in the cold.

The drawback is that your wallet will be heavier which slows your car down.

d0000000000000000d........just stop and pull your head out and smell the fresh air

there...wasnt that nice????

now....lets just get this clear.....THERE IS NO PROBLEMS WITH THE EXTRA-S IN ANY WEATHER OR TEMPERATURE UNLESS YOU ARE ABOVE THE ARCTIC CIRCLE

this is what subaru puts in their transmissions from the factory and THAT MEANS that it has to work right

or do you not understand this and why this is important????


jesus...where DO these guys COME from?????

On come on Uncle Scotty you should know better. If you have racing fluid for your transmission you get 5times its life and at least 30whp gain.

OP trust me lots of fluids out there. Most will actually cause harm to your syncros. The good ones like the Motul I had are good but not in cold, cause extra whine/noise and only help during race conditions. Why did I choose it then. I needed fluid and most dealerships wouldn't sell me extra s. Took me 2 months to find and convince a dealership to sell it to me.

Get Extra S and be done with it. As good as anything else if not better. I have yet to find 1 thread that is better than it. And best part is, extra s is a lot cheaper.

Scotty...Jeez. Calm down a bit. I have every right to ask for more opinions. Yes, I respect your opinion and I thank you for giving it to me but that doesn't mean I can't ask for more. In my car Subaru also spec'd out non-synthetic engine oil. That means they picked out a non-synthetic oil design that works for all the conditions the car will see. But does that mean you would recommend putting non-synthetic oil into your car? I don't think so. Subaru changed the new STi's to coming stock with synthetic engine oil and they had to do it for some reason. Just because they haven't changed to a different design does not mean that there is nothing better out there nor that Subaru doesn't necessarily want to. I just wanted to get some more opinions about this oil over what I found from searching. I have every right to do that without being so much called an idiot on this forum. I did my due diligence and searched before I asked questions and yet I still get this kind response....

I don't need any more responses. Thanks to those who commented back. I will be buying Extra S.

The cold weather performance of Extra-S is why I won't be running it again. Below freezing, it takes a couple of miles to warm up. Since I do not warm up my car, I got tired of not being able to downshift to 2nd at a turn about a half mile from my house (would just leave it in third). Switched to Mobil Delvac and did not have that problem last winter.

i have been here a long time and have not seen posts of people being unhappy with the extra s

one of the issues with these gearboxes is that they DO take a mile or 2 to warm up....bfd....deal with it

it never ceases to amaze me that people want to jump into a stone cold mechanical device in below freezing temperatures and expect it to function just the way it does on a bright sunny summer day


subaru likely spent a great deal of research $$$ in extra s and made sure that its performance was temperature balanced as well as they could engineer it

get the spec sheet, it says it all.

i personally use motul gear 300, with its -60 C (-76F) pour point. smooth even in -40 for me.

too bad i have to hear the carbon syncro's scream every -20 or colder startup (common 08+ STI issue)...

What is considered the "cold" temperature these problems with Extra S begin?

The reason I ask, is that the cold in Florida is a very different than being cold in Maine.

I've driven with Extra-S down into the mid teens. The shifts are a little heavy and slow for the first 1/2 mile, or so. Not a big deal, but you can't rush the shifts when you first start out.

+1 but got you 1 better. Left car all night out, completely covered to the roof with snow. Outside temp gauge in car read 4 with wind bringing it lower than that. Just like web foot. Dont rush first shifts when you start out. Worked like a champ. Sure somebody out there got worse than me with extra s

-15 degree with old extra-s the last couple of winter, things are fine. If you're worried it's too cold, shift through 1-5 with the clutch in, and then go.

That one guy earlier who doesn't let his car warm up a bit when it is cold and then complains why the trans is stiff is a moron...no really...

You go lay out in like 10 degrees all night and see stiff you will be...

This is going to sound a bit off but will be taken care of soon enough...
I have the lucas 80w90 in my 5 spd tranny and it was a little stiff in the cold but once it warmed up a bit it was much better like after 5 minutes of driving or so.

Going with the extra-S as soon as my wallet has some money in it...

imo Extra-S is too expensive, $15 a qt!! If I am going to pay $60 for tranny fluid I am going with Mobil Delvac 75w-90. That is my plan for my next fluid change coming up next month.

Use whatever you want, but to complain about the price of something that you replace every 30k? Come on, that's just silly. Using delvac will save.... $20? Over the course of 30k miles that's 0.0006 cents per mile.

IMO spend the extra & prevent doing it twice.

Sounds like you got ripped off. Went to local dealership with my own containers. Sold it to me for $6 a quart. You should probably start calling around for pricing instead of complaining about

Necro'ing this because holy crap cold winter.

I have Extra-S in the spec.B, and I can say that at -18F (-40F windchill), it's not OK. I park the car outside, and park in gear as one should. I should not have in this temperature.

Extra-S is less than 15k old, only street driven, so reasonably fresh.

It was actually hard to get the car out of gear and into neutral, stick just didn't want to move. Once it was into neutral, it was so thick that just letting the clutch out stalled the motor. After about 1min warmup it was fine idling in neutral. After about 3 min I could get into all of the gears and started on my way. From there it was much like driving in the <20F temps, just sluggish shifts and a little grindy 1->2 if you go too fast. Took about 10 full minutes before it was reasonably normal in behavior.

There was also an awful pump-sounding noise for the first 5 seconds or so after starting the car, have a feeling this was the pump responsible for trying to move the trans fluid.

I think 5w30 is also a bit thick for these temps, but that's a different discussion.
