Default Redline Oil or something else

Im thinking of putting redline oil into my wrx.
Does anyone have experience with this oil and its quality?
Would someone recommend a cheap place to buy redline or synthetic oils?

Redline has a great reputation. But, I did some i-club research a few months ago and there was all sorts of bad news about using Redline, esp in the transmission.

FWIW, history seems to have been favoring cheaper and more common oils. I use 5w30 Mobile 1 full synth in my crankcase. I change it every 3k.... not because I think its a good general rule but because I have a turbo car that I drive hard... and it gets dirty.

Read CoBB's site re:fluids.

I have yet to hear someone complain about Redline MT90 in the tranny.

I would recommend Redline for the crankcase and Subaru oil for the tranny. Jason is certainly right about the amount of complaints there have been regarding Redline's tranny oil in our trannies. It just doesn't seem to be compatible with our syncros. Redline's motor oil on the other hand I have heard no complaints about and I believe it to be a very high quality product. (But then again, who the hell am I?) Just my $.01.

You could always do a search for Redline and see what you come up with. There will be plenty of information.

I agree that their have been complaints but you have to look at what product of Redline Oil they have complained about.

Again, I have yet to see a single complaint for Redline MT90 Which if you reads Cobb TEch article is recomended.

Thanks for all the help and information regarding the oil and the extra details including transmission oils.

Are you sure? I thought that was the exact one that every one was complaining about. Are you running the MT 90?

I have seen just as much crying about royal purple as I have about Redline tranny oil. Are you running it in your car? The reason I ask is that I'm getting ready to change my fluid and I'm still not set on what to use.

I'm only at @ 28K so I'm getting ready to do my own version of 30K service. I had only heard good things about the redline products for the longest time. Recently I began researching the exact products I was going to order, only to find these people complaining etc. After honestly reading just about every thread I could find on I-Club and then reading Cobb Tuning's tech article I decided on the following:

Redline MT90 for Tranny
Redline 75/90 for Rear Diff ---- NOT 75/90NS

I feel comfortable that I will not have any complaints or problems after switching over to these products. If I do I will be very disapointed to say the least.

While I am biased towards buying from a company that is located less than thirty miles from me, I decided cold, hard, unbiased research was needed when it came to my Scoob. From what I've read and heard, it's more a matter of matching the product to your app than one of manufacturer. It's my understanding that MT90 is NOT recommended for any Subaru because it's not made to the right specs. 75W90 is the goop of choice in that regard, although as I'm just now nearing my 30k service I have tried neither, but intend to try the 75W90 based on reviews in the parts forums.

As for engine lube, I definitely give Redline's 5W30 a thumbs-up, it's been worthwhile to me, and Redline's got some very convincing lab research posted on their website. On the other hand, Mobil 1 seems to do the job as well, and both are good on my peace of mind. The tiebreaker for me is, if you call up Redline in Benicia directly, tell them you work at so-and-so garage or such-and-such car dealership, they will set aside a case for pickup at wholesale rates. With that, I think it's worth the small difference in price for the local company to get your dollar.
I am also planning on grabbing a bottle of watter wetter for both my vehicles to try them out. So far every review is either very positive or a version of no difference detected. I'm leaning towards it being a good product that some people don't know how to tell if it works or not. Will be back after I try my hand.

I had only praise about Redline's engine oil.

But I can't agree with Redline tranny oil in subie's tranny. I had 75W-90NS in tranny (the recommended one by Redline) and it feels like there isnt' sufficient friction to spin the sycro. Eventually, I had problem shifting into 5th ALWAYS.

That was while I owned a 98 Legacy GT. Now I am using Mobil 1 75W-90, and it does not have the same problem like Redline's 75W-90NS.

Default different oils for different needs

basically, you get one kind of characteristic or other. The synchros need friction from the fluid, but your gears and bearings are better off with as little as possible. So, what you feel with the shifter has to be weighed against the actual wear and tear of your gearbox. I may hav it backwards, so make sure you guys check out the other posts too. Personally, I am inclined to think that unless you have big power from your motor, the smoother shiftin is more beneficial than the difference in bearing wear, but again, I'm not educatd in he details, only an overview.

Hello,

Just to chime in, we use 75W90NS for the tranny (but we do that because the clutch-type KAAZ diff works better that way - though it makes a lot of noise with NS). NS is what you should use in the tranny because it makes shifts easier and that means less broken trannies.

We use NS in the rear diff, too, but again, that's because of the KAAZ diff.

I don't know if that helps at all, but in answer to the quality of the oil - it's the best oil I've used.

I once tried The Redline MTL in my old Bimmer's Getrag box w/ZF synchros, and it crunched synchros constantly, as the oil was too light.

Once I used MT90, I was stoked.

We also use Redline 20W50 in the crankcase, Redline CV-2 Red Moly grease in the CV Joints and rear bearings, Redline Assembly Lube for any engine work and Redline Water Wetter in the radiator.

Oh, Redline 85W140 goes in the rear diff of our Chevy 3500 Duramax tow vehicle.

And Redline MTL goes into my Miata.

It isn't cheap. We usually get ours at Monument Car Parts for around $6.40/quart. Ugh.

Gary, how much of a difference do you think the water wetter makes for EGT's?

I wouldn't think it would make much difference, if any.

So the benefit is strictly less heat buildup in the block and head? No side benefits for improved detonation resistance or fuel atomization?

We use Water Wetter because coolant is not allowed in racing (too slippery if the system opens up). Water Wetter slightly increases the cooling capacity of the system.
