MotulGear 300 75w90 100 Percent Synthetic Gear Oil 1 Liter (105777)

This is my go to transmission and rear diff oil for my Subaru. I have heard great things about the Redline products but I have had consistent good results with Motul. I have also seen people recommend the Subaru Extra S. This seems like a good product but it is a bit difficult to get in the quart sizes.Motul Gear 300 is the perfect 75w90 for me. My 2001 RS takes 0.7 quarts in the rear diff and about 3.5 quarts in the transmission. After swapping the older black oil from my diff and transmission with this stuff, I am experiencing much smoother shifts and absolutely zero grinding of gears. All my shifts are smooth as butter.This stuff may seem a bit pricey, but if you really want to protect the gears in your ride you should really look into this stuff. Nothing but good things to say about it from me.I would recommend this to anyone who is looking into swapping their manual transmission or rear diff oil. This stuff lives up to its reputation.9/2/14 EDIT:I would like to add that when doing the rear differential fluid, I had also purchased the PLEWS 55001 pump to pump the oil into the fill hole of the diff. Due to the special design of the Motul bottles, the pump DOES NOT screw onto the bottle. I ended up just holding it onto the bottle while I pumped it into the diff. It still works, however not perfectly. In my opinion, still worth the $6 I spent on the pump to make refilling the diff easier.I would also recommend giving this oil a bit more time to heat up. It is fantastic gear oil, however I have noticed it takes a minute or two for it to warm up and get that "extra buttery" feeling to it. This is perfectly fine since when it is warmed up, you will never want to use a different gear oil again. Still going strong over here..

Yeah it's pricey but I think this is pure synthetic gear oil with no friction modifiers. Better than the Mobil1 75w90. My proof is anecdotal at best, but I think as majority of the 75w90s include friction modifiers for limited slip diffs it sometimes leaves some strange symptoms, a little jerk in the rear diff at low speed, delay power when turning etc. At first glance the Motul 300 does not include any of those modifiers and it seems as a result, smoothening out those symptoms.Definitely pricey, and it's not like Mobil1 75w90 with those modifiers is unusable, it works well too, but this seems to be a little better.

I have a 2012 Chevy Traverse and it drives 50 miles every day to work , odometers 198,000 miles , so I wanted to replace rear differential with the best product possible and this was what I picked for the job. I drained old fluid and it sure needed changing!!! It should been done every 50k miles for front transfer case and rear differential gear box. Each takes 1 1/4 quarts approx. each , so have three quarts available when doing both gear boxes!

Good

Picked up the gear oil for my Vespa LX150 as it was recommended for this scooter. Changed the gearbox oil and it works. I like the pouring tip. It makes pouring it into a measuring cup easy.

Great price for product.

The best stuff you will find on the internet. Subaru owner here and my gearbox loves it. Was gonna do Uncle Scotty cocktail and found out it sucked. This works really well.

Transaxle seems to shift better
