Can I use this for my 2011 Mazdaspeed 3? (Manual transmission)

It's in my 2014 CX-5 which requires 75W-80. Works better than Mazda MTF.

What kind of improvement will I see using this over factory in an mt82 in a mustang?

Not much, it runs a tad smoother when at temp but the notorious 3rd gear issue is still present, I noticed 5th would also scratch when it got really really cold. I'm thinking about switching to ATF like most others have in accordance with Ford's specs.

I have a bmw 89 325IS and i need 80w gl-4 which one is the one i need to get?

If you have a manual transmission then you are looking at the correct one which is part number 50204

Is this safe to use in my 1980 Mercedes Benz 240D?

Did a search on Pelican Parts for your 240D and it recommends this fluid for your manual transmission.

品質、配送ともに問題なし。

並行輸入品とのことですが、容器も全く傷などなくきれいなものでした。梱包も問題なく、配送トラブルなく迅速な対応でした。オイルそのものは評価の基準がなく、変速時のスムーズさは交換前より心なしかちょっと良くなった感じがします。
