Since they won't give any info about it on their site, what makes the XPR stuff special?
|
The shop (if/when) will maybe stock these big pails and people can fill up their own containers with a pump. Good for price, and less plastic (and oil drippings) in landfills.

Also can get ENEOS oils. Anybody know anything about them?

I might be interested in a case of Amsoil what are those going for? What about Rotella? anywhere local that carries it?

Case of 12qt. Amsoil Racing 10W30 is $127.80 + tax. No 5W30 available. There is a lower grade of 100% synthetic too - $90 per case. Also gallon jugs and cases of 4x gallon jugs. |
I really hate the idea of mixing fluids, but Phil of Andrewtech is all over Nasioc recommending 3 quarts of Redline Shockproof LW mixed with one quart of Motul Gear 300 75W-90 for the 5MT. He says he spoke to Redline and this is a good mix. His logic is that the the Redline is almost perfect except that it poors poorly in cold temps. The Motul fluid is too keep it from getting too thick. If you don't want to bother with Motul, you can use Valvoline Synthetic or your favorite synthetic 75W-90.

Personally, I don't feel the need to mix fluids to make it a little more convenient to add them when it's cold out. I just put the bottles in a bucket of hot water to get them flowing better.
|
Poor wording on my part.
I don't think it's to make the fluids easier to pour into the transmission. It's to make shifting easier/smoother in the cold. Pore. |

I've got Amsoil Transmission fluid in my rally car, racing on a 15 year old transmission flying over jumps and hitting dips hard, panicked shifts in water crossings trying not to get stuck and i have no signs of transmission wear. Honestly You'de have to pay me to use a Cocktail in my transmission (and if anyone would like to lmk) :lol: Sunshine auto Stocks Amsoil , though their prices are a bit high I would recommend just ordering some through knucklesplitter and not to mix it with anything else. |
Uh, Andrewtech sort of specializes in upgraded gearboxes. http://www.andrewtechautomotive.com/services.html
They're not some startup yokel shop. |
I've heard the Severe Gear is pretty good in the 5MT, but it doesn't last as long as Gear 300. After, say, 15K miles it starts to feel like it needs a change. I'm all for regular fluid changes, but I want something that can last a long time.
And Andrewtech has probably seen more open Subaru gearboxes than any other shop in the country. I give their advice far more weight than any other single poster. However, I don't like the idea of cocktails really, either. |

Gear oils are all pretty similar, and mixing them for the most part just blends the properties of the two weights to somewhere in the middle. The chemistry of developing a new oil is probably pretty complex, but there's no chemistry really involved in blending two different weights. |
Sure, but are you saying that there's never a chance for a bad interaction between two gear fluids? I know they're designed to be compatible with eachother since there's always some of the previous fluid left over, but I'm surprised that there's no such thing as a bad interaction (like breaking down faster, unforseen reactions, etc) when mixed full strength. I mean, manufacturers test their formulas by themselves, not mixed with every other fluid out there. Maybe I'm just being paranoid, but that's how I am with my car.

And apparently mixing that Motul into lightweight shockproof is just going to lighten up the cold performance of the shockproof according to Andrewtech. Now, I probably wouldn't go around testing my own blends just because I don't want to deal with the carnage if I lighten something too much... but I'd trust a reputable gearbox shop like Andrewtech because they've probably seen it all and tried it all themselves. |
I wonder why he didn't just use Redline ULSP or standard 75w90(NS) instead of the Motul.
|
I know he hates the 75w90NS. I saw a post today where he said that it's really awful on the gear box. Is the ULSP 75w-90?
|
I'm not sure. I think it's meant for 2WD gearboxes, without differentials.

But I don't really follow the whole gear oil saga... once I tried the lightweight shockproof, that's all I use. |

The diffs require GL5 oil is all. Nothing in a Subie requires friction modifiers or anything, but you have to be careful about what you put in an STi rear diff.
