What is the best gear oil?
- Red Line MT-90 — Best Differential Fluid.
- Lucas Oil 10048 — Great for Synthetic Transmission and Differential.
- Red Line 75W90 — Gear Oil for Faster Shifting.
- Honda 08200-9003 — VTM-4 Differential Fluid.
- Mobil Delvac Syn Gear 75W90 — Fully Synthetic Differential Fluid.
- Royal Purple ROY01300 — High-Quality Synthetic Lube.
Can I use SAE 90 instead of 75W90?
Both are single grade SAE 90 oils. SAE 75W-90, is more appropriate in most climates where 90 is specified, specially if it is a transmission.
What is the difference between 80W90 and 85W140 gear oil?
The viscosity chart rates the 80W90 up to 95 degrees while the 85W140 is rated up to 120 degrees.
Is EP90 the same as SAE 90?
When it comes to Gearbox oils, many older vehicles specified EP80 or EP90 weight oils. An SAE 90 gearbox oil is roughly the same viscosity as an SAE 50 engine oil. Most manufacturers now offer EP80W/90 oils in place of both EP80 and EP90.
What does GL-5 mean in gear oil?

Is gl4 and gl5 compatible?
The main difference between GL-4 and GL-5 gear oils is the amount of EP additives. GL-4 is suitable for hypoid gear service when they are under severe service but are without shock loading. GL-5 is suitable for hypoid gear service under severe service and shock loads and not for use in a gearbox.
What does GL-4 mean in gear oil?
GL-4. Active. The designation API GL-4 denotes lubricants intended for axles with spiral bevel gears operating under moderate to severe conditions of speed and load or axles with hypoid (see note)gears operating under moderate speeds and loads.
What is the difference between 75 80 and 75 90 oil?
Technical Supremo, Platinum Member. Doubt if it’s the oil, basicly the low number is how thick the oil is when cold and the high number when hot, so the 75/90 stays slightly thicker than the 75/80 when hot, but is the same when cold.
What does API GL 5 mean?
lubricants intended
Is GL 5 a hypoid?
Gear Oil GL-5 delivers value through: Good gear life — Extreme pressure properties protect hypoid and other types of gears from scuffing and wear. The sulfur-phosphorus extreme pressure additive technology used in Gear Oil GL-5 provides good thermal and oxidation stability.
What kind of oil goes in a differential?
In a rear-wheel-drive car, the differential has its own housing and lubrication, a thick, dark oil usually heavier than 80 weight. Front-drivers typically integrate the differential in the transmission housing and share the same fluid.
Is gear oil and engine oil the same?
gear oil, you may be tempted to think they’re the same thing, but they’re not. Gear oil is specifically designed to protect, lubricate, and cool gearing systems. Engine oil lubricates the bearings and protects your car’s engine from the additives in gasoline.
Can we use engine oil in gear oil?
Home / Technical infos / F.A.Q / Can I use engine oil for the gearbox? No, the majority of gearboxes require a special formulated lubricant for the transmission system. whose crankcase is common between the engine and the transmissions. Like engine oil, the gear oil must comply with the manufacturer’s requirements.
