GL4 75W90 gear oil...

[mattwithcats]

Looking for three quarts of full synthetic GL4 75W-90 gear oil, for a decent price (under $10 a quart) Stuff has become unicorn tears... Anyone know where the unicorn graze?

UNFORTUNATELY..... it is $18 a quart! https://www.redlineoil.com/mt-90-75w90-gl-4-gear-oil I have a few applications that use GL-4 gear oil...ain't no way I'm going with synthetic on them.

Might be easier to find a "GL-5 yet still yellow metal safe" labeled oil

Bought Redline for $20 on Amazon. Also available for $60/gal. Made a huge difference on my Sorento's shifting, to my surprise.

This is as close as I could find to what your looking for: https://www.amazon.com/RAVENOL-J1C1000-0...l+MTF&psc=1 This one claims to be "Yellow metal safe" despite being GL-5 rated. https://frsport.com/MTF-Manual-Trans-GL-...KxoCAU0QAvD_BwE

I bought 2.5 gal of GL4 75-90 off Amazon when there was none to be found here. Was not too bad price and quick ship Prime.

What application are you looking to use this for. Redline has several gl4 lubes that work well in different applications. The other thing to note is Napa sells a cheap gl4 conventional gear oil with like no additives or anything. In some generic looking black bottle. I've used it before and it shifts as well as red line mt90 and MTL but you have to change it more often.

Here is some conventional 85w-90 GL4 that's very popular... https://smile.amazon.com/gp/product/B000M8RYMC/ Less than $10 a quart when bought by the gallon. This is the cheapest 75w-90 I know of at $12 a quart but its a semi-syn... https://www.amazon.com/RAVENOL-J1C1001-75W-90-Gear-Semi-Synthetic/dp/B00QPDZCCW/

That top one is available at most Napa stores.

That's the one I was looking for but couldn't find.....While it's a little over the OPs $10 requirement, I don't think he will do any better than this.

Stop being a cheap skate is my advice.

Yep, buy a dedicated MTF specifically designed for MT's such as Redline MT-90 or Amsoil MTG.

A cheapskate mineral 80W90 GL4 of inherently higher [email protected]*C is superior in components protection against a super extensive fully synthetic (or blend) 75W90 GL4 , most of the time.

I bought Redline MT90 on Ebay for $9 a quart and free shipping.

Then there's Pennzoil 75W90 GL4 which is rare as hen's teeth: http://www.pennzoil.com/en_us/products/o...2NhbGU9ZW5fdXM=

Does the [email protected]*C not matter? Redline MT/90 has a [email protected]*C of 15.6

Yes,it matters ... only when MTF temperature is 80-100*C majority of the time in, a limited # of passenger car transmissions that travels at high speed above say, 65 mph for 1 hour and above per start, with heavy loads towing or long hill climb. Fact is most passenger car transmissions max at 60-80*C, and starting sump temperatures is always near ambients of 30*C and below. Many passenger car transmissions that travels 2-4 hours non-stop at 65 mph do not hit 80*C or 75*C, btw.

Castrol Syntrans Multivehicle is what I'm using in my two Mitsubishi with Getrag gearbox. Have the feeling they cheapened out the formula a bit recently, recent oil change doesn't feel the same. There's also a Mitsubishi/Diamond stuff you might be able to buy at Mitsu dealerships. Due to the said different feeling (there was a new logo on the packaging stating some improvement in formula or whatever, and it doesn't feel as smooth as usual I'm considering switching to Castrol Transaxle, which is a GL4+. I've not been able to source the Shell Spirax locally
