![]() Valvoline’s SynPower is fully synthetic gear oil that meets API GL-5, MT-1 an MIL-PRF-2105E specifications. Valvoline SynPower Full Synthetic Gear Oil Last update on / Affiliate links / Images from Amazon Product Advertising API 5. Better for extreme conditions than moderate ones.Costs less than much of its competition.Suitable for limited-slip differentials.It can smooth operation in aging gearboxes as well, but its high sulfur content suggests it may damage brass bearing cages or other yellow metals in manual transmissions. This GL-5 rated lube is extremely slippery, reducing wear and friction in hypoid and limited-slip differentials.Īs a fully synthetic lubricant, Lucas Gear Oil’s viscosity is stable in extremely cold or hot conditions. While true, Lucas Trans and Diff Lube prevents many such issues from ever occurring. Lucas lubricants have a reputation as simply being a quick fix, delaying costly repairs. Last update on / Affiliate links / Images from Amazon Product Advertising API 4. How it achieves both designations is a mystery.Suitable for light-duty manual transmissions. ![]() Royal Purple manages to satisfy both ratings with its proprietary Synerlec additive package, which does not harm soft metals in synchronizers. Unlike many other gear lubricants, Max Gear is also suitable for GL-4 applications like manual transmissions and front-wheel-drive transaxles. Max Gear is fully synthetic, so it flows in cold temps and retains its viscosity in hot-running, heavy-duty hypoid differentials and other GL-5 applications. Royal Purple enjoys a reputation for high performance and long drain intervals, and its Max Gear lubricant lives up to the hype. Last update on / Affiliate links / Images from Amazon Product Advertising API 3. API MT-1 oil is for manual transmissions that lack synchronizers, thus requiring more thermal stability than GL-5 oils. It is used in the most severe conditions, such as hypoid gear differentials. The API GL-5 category designates oils utilizing high amounts of EP and anti-wear additives. GL-4 lubricants have these additives, and are used in differentials that operate in mild conditions. The API GL-1 designation is for manual transmission oils without friction-modifying, EP or anti-wear additives. The American Petroleum Institute defines four performance categories of gear oil. Other additives found in gear oils include metal deactivators to prevent corrosion, anti-rust agents, friction modifiers and dispersants. Sulfurized synthetic additives are now less reactive, and phosphorus-based additives contribute lubricity, as well as EP properties to gear oils. ( This article explains EP additives in more detail than there is space for here.) Sulfur was long the EP additive of choice, but its corrosive properties has led some manufacturers to find less volatile substances. ![]() Extreme pressure (EP) additives help gear oil retain its lubricating qualities in such conditions. Gear oil must overcome the high pressure in some differentials. Second, synthetics retain their properties longer, extending drain intervals. First, it flows better in the cold and retains its initial viscosity in the heat better than dinosaur oil. Synthetic gear oil offers several advantages over conventional oil that consumers would be wise to implement. Gear oil’s high viscosity helps it coat the gears and lubricate the bearings. The gears sit in a sump and carry oil with them as they turn. The best gear lubricant will prevent the metal-to-metal contact that causes friction and wears gears down, and it removes heat from around gears. (This article on Popular Mechanics’ website describes differentials and explains how to service them.) Like motor oil, gear oil has specific tasks. Depending on the configuration of the gears, the oil is required to remedy certain conditions. Whether in a manual transmission, transfer case or differential, all automobiles use gear oil of one form or another. Transfer Box ATF Nissan Matic D 1.8litres = 1. Here is some other info I found on Įngine Im leaving this out as it is covered in nissan-engines.html some where. What are you guys using? any one using is so what viscosity? Any way Ive read a lot of people over seas using TITAN SINTOPOID LS SAE 75W-90 for the rear diff and TITAN SINTOPOID SAE 75W-90 for the front. It takes me to redline on eBay, that's fine but, Redline does not sell "GL5 85/90 or GL5 80/90 so why does the link take you to that fluid? If that fluid is recommended why not link to a company that sells it. I'm a tad confused about the linking for the Diff fluids though. I'm looking for good diff fluid for the front and rear obviously.
