MT-90 75W90 GL-4 GEAR OIL Red line MT90 is a synthetic 75W90oil designed for use in synchromesh gearboxes. It provides excellent protection to gears and improves the life of synchro rings. It has a perfect coefficient of friction to allow easier and faster gear changes even when cold.

I found MTL around 20 years ago while trying to solve some crunchy gear engagement problems in a BMW. It solved the problem so well that I've been a Redline fan ever since. It ain't snake oil. It's an engineered product.https://cdn.opieoils.co.uk/images/variants/large/redline/red-line-mt90-75w-90-gl4-synthetic-manual-gear-oil-1-us-quart-0946-litre-3.jpg not trying to justify a switch away from the use of Redline here ... just wondering out loud as to why Redline has earned such a fine reputation). OK, I just went out to the garage and pulled my old blue binder factory service manual down off the shelf.

I put in 60w and that fixed the o/drive problem that you described on my car. If MT90 fixed it on yours then your accumulator seals are not quite as worn as mine apparently are. MT-90 is not for use in differentials with hypoid gears but is good for gear and synchro protection, balanced slipperiness for easier shifting in cold climates and also excellent for high- and low-mile transmissions Compatible with petroleums and other synthetics. Maybe I could do a 50/50 mix of MTL and MT90, which would give me a viscocity more or less in the middle ... the best of both worlds ... ?
