Motul Gear 300 75W-90 is Motul's ester-based racing lubricant for manual gearboxes and differentials. It uses the same ESTER Core technology as the 300V engine oils, reinforced with EP (extreme pressure) additives, and Motul specifies it for synchronised and non-synchronised gearboxes, combined gearbox/differential units, transfer cases and hypoid differentials working under shock and heavy load at low speed, or moderate load at high revs. It meets API GL-4 and API GL-5, and Motul also rates it above existing standards.
This is the standard Gear 300, not the limited-slip version. Motul specifies it for transmissions and hypoid differentials without limited-slip systems, so a car with a clutch-type LSD wants Motul Gear 300 LS 75W-90, which we list separately. Motul quotes zero shear loss — the oil still measures in grade 90 after the 20-hour KRL shear test required by SAE J306 — with a viscosity index of 171 and a −51 °C pour point, which is what gives easier shifts while the box is still cold. Motul rates it for both racing and street use.
Features:
- 100% synthetic ester base — Motul ESTER Core technology, reinforced with EP (extreme pressure) additives
- SAE 75W-90; meets API GL-4 and API GL-5, and Motul rates it above existing standards
- Non-LS version: for gearboxes and hypoid differentials without limited-slip systems
- Zero shear loss — stays in grade 90 after the SAE J306 KRL 20-hour shear test
- Viscosity index 171, pour point −51 °C, flash point 206 °C, 87.7 mm²/s at 40 °C
- Suitable for all seal types and the yellow metals used in gearbox design
- Anti-corrosion, anti-foam and anti-emulsion
- Motul rates it for both racing and street use; 1 litre (1.05 US qt) bottle
Fitment: Chosen by gearbox or differential rather than by car. Motul specifies it for all mechanical transmissions — synchronised or non-synchronised gearboxes, combined gearbox/differential units, transfer gearboxes and hypoid differentials without limited-slip systems — plus gear, bevel-gear, step-down, reduction and propeller drives running under shock and heavy load at low revolution speed, or moderate load at high revolution speed, where transmission performance needs to beat a grade 140 oil. It meets API GL-4 and API GL-5, so check which of the two your gearbox or diff calls for. Motul developed it for the gearboxes of racing and high-performance vehicles (track, speedway, rally, rally raid) but states it is suitable in both racing and street use, so it is not a track-only fluid. Motul says to take the oil change interval from the vehicle manufacturer's requirement and adjust it to your own use.
Please note: This is the non-LS version, which Motul specifies for transmissions and hypoid differentials without limited-slip systems, so a car with a clutch-type limited-slip diff needs Motul Gear 300 LS 75W-90 (the LS version we also stock) instead. Because this oil meets both API GL-4 and GL-5, still confirm which grade your gearbox or differential actually calls for before filling it.

Let customers speak for us
Solid shipping ,good communication ,great product 5stars all the way
First let's preface I have tried three other tuners. Not bad mounting or name dropping as they all were solid tunes. But Daniel just has that magic touch when tuning the 1.6 platform.
The car has a buttery smooth power band making the car feel like a larger displacement six cylinder over a turbo charged car. Plenty of fun to be had at any speed or RPM range.
He will take the time to get you dialed in perfectly for your car. No canned tunes here folks. And if you are a EK1 user three tunes for the price of one simply can't be neat.
I received the Stage 2 tune. Here are my thoughts:
- The shifts are buttery smooth
- I love the auto shift @2000rpm when cruising around town; saves me an extra 2-3mpg overall
- Driving in traffic is a dream now, much better than stock. I don't even hear that annoying shifting fork anymore, lol
- Any and all DCT slips are gone
- The increase in torque limit! This opened up my N75 Stage 3 ECU tune; I can feel the difference. The last time I dynoed, I got 289 lb-ft of torque. But it feels much more substantial than that!
- The clamping force is unreal. I did a run from a dig, and it hooked and slammed through the gears all the way to 7k rpm in each gear. Amazing.
Conclusion: This TCU tune is a must-have. If you have an N75 ECU tune, it is an absolute game-changer! Especially with the Redline MT-LV fluid that I'm running. I can't wait to get my retune with water meth injection. Daniel and the rest of the N75 team are the best!
Works like suppose to be fast delivery after installation 5 minutes drive TPMS sensors lights off everything is normal like from factory 👍👍👍

Product was very easy to install and what a difference in shifting also n75 was super awesome to deal with will shop here again
After using the N75 tune for a couple of months, I can confidently say that it offers the best value for your money on the market. I've tried SXTH and LAP3 tunes before, but since switching to N75, I won't look back. With top-notch customer support, it ensures your car performs better, turning heads at every car meet.
Been running stage 2 off that bat and had some problems here and their regarding fueling. Daniel has been with me the whole way, answering questions and adjusting tunes while adding revisions whenever asked. He answers every question I ask even when they don’t relate to tuning.
Highly highly recommend N75!
Daniel's tuning and customer service makes this product a 10 out of 10. I'm new to tuning and he made the process a breeze. I literally laughed out loud when I first drove the car after installing the stage 2 tune. I still can't believe the difference.
Love the intake, fitment is superb, instal was easy and best of all n75’s customer support is stellar and way above average!
