Recommended Posts

1991 loyale 5spd. when i bought the car a year ago i changed the lube in the manual trans. i put in 80w90 as per the owners manual...i was wondering if anyone had an alternative that wont set up as hard in the winter, heat up faster and give me better fuel mileage! any ideas? thanks!:headbang: :headbang: :headbang: rock on

Amsoil makes synthetic gear lubes. I used it in my 78 4WD wagon. It shifted like it was warmed up all year round. Even dead cold 0 degrees in the AM. With the original regular gear lube the car practically slowed down to where I would want to go back to 1st before I could get the shifter from 1st to 2nd.

 

My 3ATs also shift better cold with the synthetic ATF.

Lots of racers runs straight ATF. Lower gear resistance = faster speeds, quicker shifts, and better mileage. Start shopping for a couple extra trannies for when you wear them out.

 

Personally I run the Redline with the additive for older MT's. It helps the syncro's, but can take a few thousand miles to really notice it.

yep, I put Redline 75w90NS in mine. Made a world of difference. I still need to double clutch to downshift nicely, but at least I can shift at all now.

yeah, ive heard about the whole atf thing, never sounded like a great idea, it gets cold here, like -10 in the winter as the worst i remember. i heard royal purple makes a great gear lube. also, what should i use in the rear diff.? same stuff? i will look into the Redline 75w90NS though! thanks!

Royal Purple does make some great gear lubes. The line is called Max-Gear. It exceeds GL-4 and GL-5 lubricant performance standards, and if I remember correctly, Subaru trannies require fluid that meets GL-5 standards. As soon as I get back Stateside, I plan on changing all the fluids my GL-10 over to Royal Purple products.:banana:

 

As for the rear diff, it takes the same fluid as the manual transmission(usually 80W90).

IIRC, the tranny takes 4 or 5 quarts, and the rear diff takes like 3 or 4, but I could be wrong. It has been awhile since I changed the fluids in my GL-10, so don't quote me on those numbers. They might give you a starting point though.

BG synchroshift II - full synthetic. Pretty expensive, but that's what I've been using in my tranny for a couple years, and seems to work great for protection and shifting ease.

is this anything like "gm synchromesh" oil? i use wuotes because its a product ive heard my brother talk about, and talked with him about it, ALOT.. but never actually seen a package....

 

he swears by it, had a civic tranny that gradually got harder and harder to put into 2nd.. finally it wouldnt give for nothing, and he replaced the oil with synchromesh (had replaced it with standrad lube already) and after about 100 miles you couldnt tell there had EVER been a problem.

 

he said it was something like 15-18 bucks a quart, but worth it. I figure if its gonna be in there for 20K miles (or more, lets be honest) then i guess its worth it.

Here's more info about BG synchroshift from a quick google. There are two types synchroshift I and synchroshift II. From what I've read GM and Pennzoil products are very similar and BG is a different level of quality. Caboobaru....thanks for the "compliment" ha ha.
