It is especially recommended for gearboxes that are hard to shift or noisy, where the extreme pressure formulation and low pour point help restore smoother operation.\u003c\/p\u003e\n\n\u003cstrong\u003eCan I use MOTYLGEAR 75W90 in a limited slip differential?\u003c\/strong\u003e\n\u003cp\u003eNo. MOTYLGEAR 75W90 does not contain friction modifiers and is not suitable for limited slip differentials (LSD), posi-traction units, or torque-sensing differentials that require an LSD-compatible fluid. Using it in an LSD application may cause chatter, shudder, or accelerated clutch pack wear. Use a fluid specifically rated for limited slip applications in those cases.\u003c\/p\u003e\n\n\u003cstrong\u003eDoes MOTYLGEAR 75W90 meet API GL-5 and GL-4 simultaneously?\u003c\/strong\u003e\n\u003cp\u003eYes. MOTYLGEAR 75W90 meets both API GL-4 and API GL-5 standards, as well as MIL-L-2105D. This dual rating makes it suitable for a wide range of manual gearboxes that specify either GL-4 or GL-5, but always verify your vehicle manufacturer's specific recommendation before filling.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat is the difference between MOTYLGEAR 75W90 and a fully synthetic gear oil?\u003c\/strong\u003e\n\u003cp\u003eMOTYLGEAR 75W90 uses Motul's Technosynthese technology, which blends high-quality mineral and synthetic base stocks. A fully synthetic gear oil uses 100% synthetic base stocks. MOTYLGEAR 75W90 delivers excellent thermal stability, shear resistance, and cold-weather performance at a more accessible price point than a full synthetic, while still meeting GL-4 \/ GL-5 specifications.\u003c\/p\u003e\n\n\u003cstrong\u003eHow does the viscosity index of 175 benefit performance?\u003c\/strong\u003e\n\u003cp\u003eA viscosity index of 175 means the fluid's viscosity changes relatively little across a wide temperature range. At cold temperatures, MOTYLGEAR 75W90 remains fluid enough for easy gear engagement (pour point -50°C \/ -58°F). At high operating temperatures, it retains a sufficient oil film for gear protection. This wide VI reduces wear during cold starts and prevents thermal breakdown at sustained high loads.\u003c\/p\u003e\n\n\u003cstrong\u003eHow often should MOTYLGEAR 75W90 be changed?\u003c\/strong\u003e\n\u003cp\u003eChange intervals should follow the vehicle manufacturer's specifications and be adjusted based on severity of use. Off-road, track, or towing applications subject the fluid to more stress and may require more frequent changes than highway driving. Inspect the fluid condition during oil change intervals and replace if it appears contaminated, discolored, or if the transmission develops noise.\u003c\/p\u003e\n\n\u003cstrong\u003eIs MOTYLGEAR 75W90 compatible with transmission seals?\u003c\/strong\u003e\n\u003cp\u003eYes. Motul formulates MOTYLGEAR 75W90 to be compatible with all seal types and yellow metal materials (brass, bronze, copper alloys) commonly used in gearbox construction. It will not swell, shrink, or degrade standard gearbox seals under normal operating conditions.\u003c\/p\u003e\n\n\u003cstrong\u003eHow much does one liter of MOTYLGEAR 75W90 cover?\u003c\/strong\u003e\n\u003cp\u003eOne liter (MOT109055) is sufficient for top-off service on many manual gearboxes or as part of a partial fill. Most manual transmissions hold between 1.5 and 3 liters total. Check your service manual for the exact fluid capacity of your specific transmission to determine how many liters are needed for a full drain and fill service.\u003c\/p\u003e\n\n\u003ch4\u003eInstallation Instructions\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eWarm up the vehicle by driving for 5 to 10 minutes to allow the existing fluid to drain more completely.\u003c\/li\u003e\n\u003cli\u003ePlace a drain pan of adequate size under the transmission drain plug.\u003c\/li\u003e\n\u003cli\u003eRemove the fill plug first before removing the drain plug to ensure the fill port is accessible.\u003c\/li\u003e\n\u003cli\u003eRemove the drain plug and allow old fluid to drain completely.\u003c\/li\u003e\n\u003cli\u003eReinstall and torque the drain plug to the manufacturer's specification.\u003c\/li\u003e\n\u003cli\u003eFill the transmission with Motul MOTYLGEAR 75W90 through the fill port until fluid begins to seep out or until the correct measured volume has been added per the service manual specification.\u003c\/li\u003e\n\u003cli\u003eReinstall the fill plug and torque to specification.\u003c\/li\u003e\n\u003cli\u003eWipe down any spilled fluid and check for leaks with the vehicle at operating temperature.\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003cp\u003e\u003cstrong\u003eWARNING:\u003c\/strong\u003e This product can expose you to chemicals including lead and phthalates, which are known to the State of California to cause cancer and reproductive harm.
