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).This Gear Oil is suitable and popular for most RX-8 and RX-7 Transmissions. 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. https://cdn.opieoils.co.uk/images/variants/medium/redline/red-line-mt90-75w-90-gl4-synthetic-manual-gear-oil-1-us-quart-0946-litre-2.jpg Satisfies the gear oil viscosity requirements of 75W90, 80W90, 90 and motor oil viscosities of SAE 40, 10W40 and 15W40

RED LINE MT-90 HIGH-PERFORMANCE GEAR OIL is a fully-synthetic ester-based lubricant designed for use in manual transmissions and front-wheel-drive transaxles. This shear-stable formula resists breakdown for extended periods and offers more consistent viscosity in warm and cold temperatures for less gear noise and improved shifting. This fluid is less slippery for improved synchronizer coefficient of friction and offers stronger film strength for better wear protection. Where I live I'm a fan of MT90. But if you drive your car when it's cold outside MTL would likely be the best choice. If you have any doubts just call Redline-- I'm sure they'd happily advise you. In any case, you won't be regret installing either MTL or MT90. Based upon the weights of the MTL vs. MT90, looks like the MT90 better meets the 90 weight spec, so there you go!Satisfies the gear oil viscosity requirements of 75W90, 80W90, 90 and engine oil viscosities of SAE 40, 10W40 and 15W40 I switched to redline MT90. That didn't cure the o/drive problem but the transmission seemed to shift a little smoother... 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 OK, I just went out to the garage and pulled my old blue binder factory service manual down off the shelf.
