Gear oil MOTUL or RED LINE

MOTUL Gear oil

Brakes are genuinely impressive for this segment. Only real issue I faced was chain wear — once you start maintaining it, it improves. I lube mine with 2T gear oil, works surprisingly well. Used Motul for most services, but the last one was with Prolube and the bike feels a bit rougher since then.

Pros: impressive brakes
Cons: chain wear, rougher with Prolube
Mileage: 12000 km

Rating 4.0

When I was researching MTF I found several experience that said the older Toyota transmissions get a little crunchy on the RedLine and I saw lots of good reports for Motul 300 75W-90 so I used that in mine earlier this year. It doesn't have issues but the shifting is ever so slightly smoother.

Pros: shifting is slightly smoother
Cons: crunchy on the RedLine
Vehicle: Toyota

MOTUL Gear oil

Fresh gear oil can help grinding synchros. It sounds weird, but it's true. 75w90 GL5 is the oil you need. Motul gear 300 is the most recommended gear oil brand for subarus, but any GL5 rated 75w90 gear oil will probably help a lot.

Pros: helps grinding synchros, highly recommended
Vehicle: Subaru

RED LINE Gear oil

I had tried Redline MT90 to get rid of the intermittent grind into 2nd, but it made all shifting more difficult and always grind into 2nd. So I went back to OEM.

Cons: made shifting more difficult
Vehicle: Volkswagen Corrado
