Between going out and buying a siphon pump because you overfilled your tranny, and replacing a drain plug gasket because it gets a little oil on it, I think this guy is a little weird.
That's funny though. The guys at Subaru told me they replace the oil plug gasket every time they do an oil change. Is this just some mumbo-jumbo to keep me from going to my "other" mechanic?

Replacing drainplug gaskets cant hurt, and they are cheap, so its not a bad idea, but a leaky drain plug gasket is not going to dump all your oil and cause a catasrophic failure.

Id say the advantage of going to the dealership is they will use the oem filter and they will like you more when it comes time to get some warranty work done. Dont expect the bulk oil they use to be any good though.

Tomorrow I'm going to get it changed, and with 10K on my car I'm switching to Mobil 1 Synthetic. Subaru should be able to handle that one. They say that's what they use for their synthetic. Then again, I've heard of stories where they say they use it but they don't to save $$$.

If you can't do the easy oil change your self (no offense), I'd go to the dealer just because they have more accountability than say the mom and pop lube shop or Paco at Jiffy Lube who will use recycled oil in your engine and overtighten (or possibly not tighten securely) your oil bolt.

A guy I know in our local car club had his oil changed earlier in the morning several Saturdays ago and the idiot 'lube-tech' at Jiffy Lube did not fasten the oil bolt securely enough that later that same night when he was driving it came undone and spilled all of it out on the road. 4 or 5 of us pulled to the side because his car overheated and we soon concluded from the thick, long oil streak what happened. When we opened his hood his header was orange-red from the heat. We couldn't believe the sight. It looked like one of those Katanas a Japanese sword maker would heat up to mend sharp with a hammer...

Sometimes it pays to do things yourself. Would you purposely do a bad job or ruin your own vehicle? Of course not, so go to Sears, buy a couple mechanics sets and the service manual from Subaru and then you will have everything done well and perfectly. Personally I even use a torque wrench set to 33 lbs. and use 11 lbs. on the filter wrench. That way I torque every part related to the oil change precisely.
DAMN! No I know a guy that works on German cars (I used to have a Jetta) and I let him do work on my Scooby. NEVER Jiffy Lube!!!

It is some sort of metal, but it is a "crush" washer that is only to be used one time. It has a ring on it that compresses the 1st time you use it. If you try to use it again most often you have to use unnecessary pressure to get it to work. This is where the problem lies...

Yep, no crush washer here either. Just a big hefty washer on the drain plug (both tranny and engine oil). I know what a crush washer is and I definitely don't have one. I've changed my engine oil six times myself and not a single leak.

I'm not disagreeing with anyone, just stating my situation.

I just bought one today because I've got MT-90 coming in 2 days. It's a crush washer. You wouldn't be able to tell after it's been used...

Not sure what you mean but its pretty easy to identify a used crush washer, its crushed...

And mine does not have crush washers. I was very careful about that with the first oil change and there was no crush washer. A used crush washer doesnt disappear, its just a crushed crush washer.

04EJ20 ... keep us posted about how you like the MT-90.

I'm going to suck out a quart of my oem MT oil and replace it with a quart of MT-90. Straight MT-90 was great ... just chickened out after a few K's ... now trying a mixture ...

Just remember that if you are trying to get easier downshifts, faster upshifts ... you need more friction to get those synchros working ... super slick synthetics won't help in that regard ...

well .... ?

I'm going to replace 1.5 qts. of my oem MT oil with MT-90 ... and see if it helps with easier down shifts and faster up shifts without crunching. Of course having a short shifter makes it easier to beat the syncros ...

Hoping this mix will be a decent safe combination ...

Hold off on that man. My tranny w/ 75W90NS is horrible. Shifting in to 4th grinds everytime, but shifting in to reverse is better (big deal!). I let you know jow I make out w/ the MT-90. From what it sounds like, these guys like it too...

Reading through the redline blurb, it appears that the MT would be a good choice. If it doesn't work- shockproof will.

I read the part about "This product is not designed for use in a rear-wheel drive differential which requires a GL-5 lubricant."

I would extend that to mean that it is not designed for our front differential, which also requires a GL-5 lubricant (and is designed much like a RWD differential).

I personally changed to Shockproof superlight two weeks ago. No problems before the change, no problems now. The only possible change is that I can drive around in 4th at 32 mph, where before the lowest it wouldn't bog down was 35 mph. But that could be my imagination...

The more I read about GL4, GL5 lubricants the more confused I get. There so many mixed messages about which to use, which corrode, ect.

like me, i suggest you keep wondering where all the people with worn out bearings and gears are.

i see stories of worn out syncros all the time.

But whats the point of having a WRX if you have to pause while shifting up to 2nd ...

Maybe by using a lube (MT-90) that allows the synchros to work easier ... they will last longer ... ?

Obvioulsy Cobb Tunning wouldn't mind selling you are new gearbox ... although most of us would get our replacement gearbox from a dealer ... but they do sort of stick their neck out "recommending" MT-90 ....

Ok, I'll hold off. I now don't know what to do...

I can only say this with confidence, the Mobil 1 Syn results in more grinding when putting the car in 1st. Many people have said that its actually too "slippery" and doesnt have enough friction.

I went to Mobil 1 to try and fix the problem I had with blocking 1st gear. That has reduced a little, but now I have the grinding instead.

Who knows.

Let us know how the MT90 works out.
