Since iam a Bitog guy I have to change the lube in my new used mazda 626 transaxle. The owners manual says it takes gl4 or gl5 80/90 weight. Im not too familiar with transaxles but in my trucks i always used a quality gear oil with limited slip additives. Do i have to use a gear oil with limited slip additives or just plain gear lube. Is it unusual that this transmission will take gl4 or gl5?

You don't need limited slip additives for this car. I have used GL4 Redline 75W-90 with good success in this transaxle.
It's common for a manufacturer to allow both GL-4 or GL-5, as long as there isn't any brass in there. GL-5s usually don't work too well with synchros, but it sounds like you've had success using them with LSD additives.
I'd use a 75W-90 GL-4 that's specifically designed for manual transmissions, like Redline MT-90 or Amsoil MTG. You won't need any additives with those. I currently have MT-90 in my Mazda3.

I'm guessing you have a Mazda "G5M" transaxle. I have had 2 cars with this transaxle and love it - smooth shifting and never a problem. I currently have a Redline mix in the one in my Ford: 2 qts MT90 and 1 qt MTL - shifts great in all temps.

loco - Use a Quality dedicated gear oil in a manual trans or transaxle.
Like Amsoil or Redline. I also use the Redline MTL/MT 90 mix in a similar transaxle. Really nice shifting.

You can run GL4 or GL5 if the GL5 says it is also backwards compatible with GL4. However, genuine GL4 is ideal in your situation.
Limited Slip additives are only there in truck rear ends to prevent the clutches from chattering. They serve no purpose in gear drives that have no wet clutches.
