This 75W90 GL-4 gear oil is the most popular choice for manual transmissions in Toyota, Nissan, Mazda, Mitsubishi, and many other imports. Formulated with polyol ester base stocks, it provides exceptional film strength and thermal stability, ensuring your gears remain protected even under the high-heat conditions of track days or spirited canyon runs. Because it lacks the reactive sulfurs found in most GL-5 fluids, it is completely safe for brass, bronze, and copper synchronizers, preventing the long-term chemical wear that leads to grinding and transmission failure.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"5\"\u003e\u003cb data-path-to-node=\"5\" data-index-in-node=\"0\"\u003eWhat’s Included in the Box:\u003c\/b\u003e\u003c\/h3\u003e\n\u003cp data-path-to-node=\"6,0,0\"\u003e- (1) 1 Quart (0.946L) Bottle: Standard neck design compatible with most common fluid pumps.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"7\"\u003e\u003cb data-path-to-node=\"7\" data-index-in-node=\"0\"\u003eThe Red Line Advantage\u003c\/b\u003e\u003c\/h3\u003e\n\u003cp data-path-to-node=\"8,0,0\"\u003e\u003cb data-path-to-node=\"8,0,0\" data-index-in-node=\"0\"\u003e- Synchronizer Harmony:\u003c\/b\u003e Specifically balanced friction levels allow synchronizers to lock up quickly, reducing shift effort and eliminating gear clash.\u003c\/p\u003e\n\u003cp data-path-to-node=\"8,1,0\"\u003e\u003cb data-path-to-node=\"8,1,0\" data-index-in-node=\"0\"\u003e- Safe for Yellow Metals:\u003c\/b\u003e Formulated without the aggressive sulfur additives found in GL-5 oils, ensuring your brass synchros don't corrode or \"thin out\" over time.\u003c\/p\u003e\n\u003cp data-path-to-node=\"8,2,0\"\u003e\u003cb data-path-to-node=\"8,2,0\" data-index-in-node=\"0\"\u003e- Ester-Based Stability:\u003c\/b\u003e Provides an unshearable oil film that maintains its 90-grade protection even at extreme operating temperatures.\u003c\/p\u003e\n\u003cp data-path-to-node=\"8,3,0\"\u003e\u003cb data-path-to-node=\"8,3,0\" data-index-in-node=\"0\"\u003e- Superior Cold Shifting:\u003c\/b\u003e Stays fluid in freezing temperatures, allowing for smooth shifting from the moment you pull out of your driveway.\u003c\/p\u003e\n\u003cp data-path-to-node=\"8,4,0\"\u003e\u003cb data-path-to-node=\"8,4,0\" data-index-in-node=\"0\"\u003e- High-Heat Endurance:\u003c\/b\u003e Resists thermal breakdown and oxidation, keeping your transmission internals clean and extending the life of your seals.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"9\"\u003e\u003cb data-path-to-node=\"9\" data-index-in-node=\"0\"\u003eProduct Specifications\u003c\/b\u003e\u003c\/h3\u003e\n\u003cp data-path-to-node=\"10,0,0\"\u003e\u003cb data-path-to-node=\"10,0,0\" data-index-in-node=\"0\"\u003e- Part Number:\u003c\/b\u003e 50304\u003c\/p\u003e\n\u003cp data-path-to-node=\"10,1,0\"\u003e\u003cb data-path-to-node=\"10,1,0\" data-index-in-node=\"0\"\u003e- Viscosity Grade:\u003c\/b\u003e SAE 75W90\u003c\/p\u003e\n\u003cp data-path-to-node=\"10,2,0\"\u003e\u003cb data-path-to-node=\"10,2,0\" data-index-in-node=\"0\"\u003e- Standard:\u003c\/b\u003e API GL-4, GL-3, GL-1, MT-1\u003c\/p\u003e\n\u003cp data-path-to-node=\"10,3,0\"\u003e\u003cb data-path-to-node=\"10,3,0\" data-index-in-node=\"0\"\u003e- Viscosity at 100°C:\u003c\/b\u003e 15.6 cSt\u003c\/p\u003e\n\u003cp data-path-to-node=\"10,4,0\"\u003e\u003cb data-path-to-node=\"10,4,0\" data-index-in-node=\"0\"\u003e- Viscosity Index:\u003c\/b\u003e 177\u003c\/p\u003e\n\u003cp data-path-to-node=\"10,5,0\"\u003e\u003cb data-path-to-node=\"10,5,0\" data-index-in-node=\"0\"\u003e- Flash Point:\u003c\/b\u003e 250°C \/ 482°F\u003c\/p\u003e\n\u003cp data-path-to-node=\"10,6,0\"\u003e\u003cb data-path-to-node=\"10,6,0\" data-index-in-node=\"0\"\u003e- Pour Point:\u003c\/b\u003e -45°C \/ -49°F\u003c\/p\u003e\n\u003cblockquote data-path-to-node=\"11\"\u003e\n\u003cp data-path-to-node=\"11,0\"\u003e\u003cb data-path-to-node=\"11,0\" data-index-in-node=\"0\"\u003ePrecision Tip:\u003c\/b\u003e MT-90 is a \u003cb data-path-to-node=\"11,0\" data-index-in-node=\"26\"\u003eGL-4\u003c\/b\u003e fluid, meaning it is intended for manual transmissions and transaxles.
