Gear oil

Match the oil to your transmission type (manual, automatic, or CVT) and the gear load it handles. For manuals, look for GL-5 oils in viscosities like 75W-90 or 80W-90. For automatics, select ATF-grade fluids such as Dexron VI; for CVTs, pick CVT-specific synthetic gear oil. In this lineup you’ll see 75W-90 and 80W-90 GL-5 options, Dexron VI–compatible oils, and a CVT-specific formula to cover these needs.

The most complex attribute to compare is the combination of viscosity grade and spec (GL-5, Dexron VI, or CVT) because it determines protection and compatibility under different temperatures and loads. A lower cold-start viscosity helps with easy starting in cold weather, while the right high-temperature viscosity protects under heavy loads. GL-5 signals suitability for manual hypoid gears, Dexron VI for automatics, and CVT oils require CVT-specific formulations. This range includes 75W-90 or 80W-90 GL-5, Dexron VI ATF, and CVT-specific synthetic options to cover these needs.

For a DIY hobbyist working on a manual gearbox, choose a GL-5 oil in 75W-90 or 80W-90 to protect gears under load. For a commuter with an automatic transmission, select an ATF-grade fluid such as Dexron VI; for CVT-equipped vehicles, use a CVT-specific synthetic gear oil. This range includes GL-5 75W-90/80W-90 oils, Dexron VI–compatible liquids, and a CVT-specific formula to match your drivetrain without guesswork.

Always confirm the required specification from your vehicle’s manual and ensure the label reflects GL-5, Dexron VI, or CVT as appropriate. Do not mix different oil types, as formulations differ and can compromise protection. Perform regular service intervals by draining old oil and refilling with the correct grade, use clean pouring equipment, and dispose of used oil responsibly. When in doubt, stick to one compatible option such as a GL-5 75W-90 for manuals or a Dexron VI ATF for automatics.

Yes: oils labeled GL-5 with 75W-90 or 80W-90 provide strong wear protection for hypoid gears and high-load conditions. There are multipurpose options like GL-4 75W-90 designed for gear boxes and differentials where EP-type oils are specified, making them versatile for various drivetrain configurations. This range includes multipurpose formulations suitable for a variety of gear systems beyond a single vehicle type.

Check the transmission specification (GL-5, Dexron VI, or CVT), the viscosity grade (75W-90 or 80W-90), and the packaging size (1L or 4L) to match your maintenance needs. Also consider brand reliability and seller credibility to ensure you receive a fresh, new product. This assortment includes oils designed for manuals, automatics, and CVTs, with options in multiple sizes to suit topping up versus full-service intervals.
