Mobilith SHC 100 is an antiwear and extreme pressure grease primarily recommended for higher speed applications such as electric motors, where reduced friction, low wear and long service life are required. It is an NLGI 2 Grade / ISO VG 100 grease with a synthetic base fluid.

GRADES:VG 68, 100, 150, 220, 320, 460 & 680.

Helps reduce friction and increase efficiency in sliding mechanisms such as gearing, with potential for reduced power consumption and lower steady-state operating temperatures.

Monograde gear oil is designed for use in “normal” temperatures while multigrade gear oil can be used at hotter and cooler temperatures. Rust-prevention gear oils protect and extend the life of gears running at higher temperatures and are best used in low-load gearboxes.

When comparing the appearance of engine oil vs. 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.

Mobilith SHC 100 is an antiwear and extreme pressure grease primarily recommended for higher speed applications such as electric motors, where reduced friction, low wear and long service life are required. It is an NLGI 2 Grade / ISO VG 100 grease with a synthetic base fluid.

The drawbacks of synthetic oils would include their cost and solubility concerns. PAOs generally have low solubility, which means they do not dissolve additives as readily as their mineral counterparts. Synthetic oils also have a difficult time suspending varnish-forming degradation byproducts.

Synthetic lubricants have a lower friction coefficient in a gearbox, better film strength and a better relationship between viscosity and temperature (viscosity index, VI). This indicates synthetic lubricants can be used at lower viscosity grades and lower temperatures.

Using the wrong fluid can cause poor lubrication, overheating, and possibly transmission failure. A mechanic might not be able to reverse the damage, even by flushing the transmission. Mistakenly adding motor oil or brake fluid can also destroy your transmission. 7.

A straightforward answer would be No because gear oil and transmission fluid target different types of transmissions or mechanical environments. Gear oil is a lubricant for manual transmission while transmission fluid is a lubricant for the automatic transmission of semi-trucks and other heavy and light-duty vehicles.

While there are many variations, gear lubricants can generally be placed into three categories: R & O, antiscuff and compounded. The gear lubricant type that best fits a given application will be determined by the operating conditions.

How often do you change gear oil? ›

Most manufacturers recommend changing the gear oil at 60,000-80,000 miles unless the vehicle is used for towing or off-roading. Then, the recommended time drops to 20,000-50,000 miles.

Not only does AMSOIL exceed industry standards and outperform competing brands, it fights viscosity breakdown 46% better than Mobil 1. It's built to stand up to the devastating effects of high-horsepower, modern engines and provide maximum protection.

Testing under the current industry performance standard from the International Lubricants Standardization and Approval Committee (ILSAC) shows that Mobil 1™ outperforms not only conventional motor oils, but other full synthetics as well. In fact, it performs far better than industry standards.

Mobil and shell are both good options. Go for what is cheap. Both have a good additive pack. Mobil1 (0w-40) has a higher viscosity Index while Shell helix ultra is lighter as per specs on paper.

Because Mobil 1 works much faster, the engine reaches peak operating efficiency much sooner. Mobil 1's robust antioxidant system resists oxidation and oil thickening better than conventional oils, resulting in lower friction and better fuel economy.

Yes. Mobil 1 is fully compatible with conventional motor oils, semi‐synthetic motor oils and other synthetic motor oils, should it be necessary to mix them. But the superior performance of Mobil 1 will be reduced by diluting it.

Mobil 1 Extended Performance synthetic oil is recommended for oil change intervals up to 20,000 miles or one year, whichever occurs first.

If you own a car that runs on synthetic oil, you're probably wondering, “How often do you change synthetic oil?” Depending on the type of car you have, most synthetic oils last between 7,500 miles and 15,000 miles.

Good quality oil does not have to be expensive but it does have to meet the given industry standards. These standards are the minimum specification requirements needed for an engine to run smoothly and efficiently. When buying oil for your car, the first thing you should do is consult your owner´s manual.

What is the difference between 75w90 and 80w90 gear oil? ›

SAE 75W-90 maintains a more consistent thickness, or viscosity, across a wide temperature range. It's thicker when exposed to high heat and thinner under colder, wintry conditions than 80W-90. The use of 75W-90 gear oil is recognized by OEMs as a contributor to overall fuel economy.

The number indicates a level of the oil viscosity at a particular temperature. The higher the grade number, the higher the oil viscosity. Viscosity of gear oils designated with a number only without the letter “W” (SAE 80, SAE 90, SAE 140 etc.) was specified at the temperature 212°F (100°C).

If your oil is dark brown, black, or light pink (usually due to water contamination), then you need to change it. Red-brown, semi-transparent fluid is often slightly degraded, but doesn't necessarily signify a need for a change.

An oil that is too thin for a tooth design will cause the gears to make metal on metal contact, causing premature wear. Too thick and excess drag is caused, reducing economy and sapping power.

The American Petroleum Institute (API) classifies gears using GL ratings, ranging from GL-1 to GL-5. Higher GL rating numbers represent more severe applications; GL-1 is the least severe and can usually be satisfied with a motor oil, while GL-5 is the most severe GL rating.

75W90 has a higher kinematic viscosity than 75W80. At 75W90 the kinematic viscosity is 13.5 to 18.4 mm²/s. 75W90 offers better shear stability than 75W80 and can generally withstand higher loads in the transmission. Oils of different SAE classes can be mixed with each other.

Synthetic oils have better resistance to aging and high temperatures and a longer service life than mineral oils. Depending on the base oil (SHC or PAG), the oil change intervals may be three to five times longer at the same operating temperature.

L S ENERGY SAVER GEAR OIL has incorporated in it a proven extreme pressure gear additive package and a friction modifier system. L S ENERGY SAVER GEAR OIL is formulated to offer enhanced lubricity and limited slip performance. In fact the L S in the name of the product stands for "Limited Slip."

Fluid capacity 28zo/flat sump or 48oz/deep sump. Fluid type – GM#1052271 petroleum based or GM#12346190 synthetic.

What viscosity is Mobil SHC 627? ›

Mineral oils are refined petroleum oils[1]blended with very small amounts of additives such as pour point depressants [2]and anti-oxidants. Whereas, synthetic oils are mineral oils that have been chemically engineered to improve its lubricating properties.

Multigrade oil can improve lower temperature cranking in cold weather. It causes less battery drain. Offers excellent high temperature performance. Designed for longer oil change intervals due to increased oxidation stability.

Mobil 1 is the umbrella branding for all of the ExxonMobil “full synthetic” gasoline engine oils. There are lots of versions and viscosity grades. There is no legal definition of “synthetic” for engine oils.

The term synthetic hydrocarbon (SHC) is a general term. Several synthetic base oil types fall into the SHC category. These include PAOs and also relatively common polyisobutenes (PIB), which are sometimes used as oil additives or as base oils in two-stroke engines.

The DURATRAN™ THF/UTTO line of heavy-duty transmission-hydraulic fluids is designed for use in farm tractors, mining and construction equipment with a common oil system for transmission, differential, hydraulic, power take-off, wet brake and power-steering mechanisms.

Gear oil is a special type of highly viscous lubricant that is well adapted for use in differentials and transmissions, including final drives. Gear oil, also referred to as gear lube, is the lubricant for the planetary side of a final drive.

There are two categories: gasoline and diesel. Category S is for “Spark Ignition”, for Gasoline and category C is for “Compression Ignition', for Diesel. For both, the letter S or C is followed by another letter. For example, SM or CF. The higher the letter, the more recent the technology of the oil.

Is gear oil the same as transmission fluid? ›

The most obvious answer to this question is that gear oil is generally intended for use in manual gear boxes and transmission fluid is for automatic transmissions.

Max Power GEAR OIL Grade: 150, 220, 320

Very good wear protection. High safety margin against foaming and corrosion. Reasonable viscosity /temperature and cold flow properties.

AMSOIL Synthetic Tractor Hydraulic/Transmission Oil is recommended for equipment combinations of transmissions, hydraulic systems, final drives, power take-off systems and wet brakes operating in “all-weather” hot and cold temperatures, including, but not limited to, those listed below.

Hydraulic oils protect machinery against water emulsion thanks to their capacity to quickly separate it. Apart from tractors and agriculture machinery, they can be used in mining, construction, metal works, and similar heavy-duty industries.

They are formulated to protect gear teeth from wear in its earliest stages, which can lead to significant gear tooth damage later on. Typical hydraulic oils do not have these properties, and are unable to provide sufficient wear protection for the higher leads on gear teeth.

Using the wrong fluid can cause poor lubrication, overheating, and possibly transmission failure. A mechanic might not be able to reverse the damage, even by flushing the transmission. Mistakenly adding motor oil or brake fluid can also destroy your transmission.

Mixing Different Gear Oils

Some lubricants just can't be mixed with others, and different grades should never be mixed together--and grease and gear oil should never be mixed, either. For example, when different types of lubricants are mixed together, they may contain chemicals that are not compatible.

"SN" oils provide improved performance compared to "SL" oils in terms of protecting against wear and deposits, and maintaining engine cleanliness.

Your dipstick reading should range from L to F. L being low, and F being full. It's best to fill your engine close or at to the F mark, but be careful not to overfill.

CD — Diesel Engine Service

Oils designed for this service were introduced in 1955 and provide protection from bearing corrosion and from high-temperature deposits in these diesel engines.
