Severe Gear®: The Right Tool For The Job

Written by Charleen

Worlds Best Differential Oil – SEVERE GEAR®:

Here in Sioux Falls we have to stock more and more all the time. makes me wish I bought a several pallets back way back when.  But it makes a HUGE difference. Temperature alone!

Your vehicle’s differential is likely not top of mind while hauling snowmobiles or ATVs for a fun weekend on the trails. Unfortunately, towing is in the severe service category and places extreme stress on your drivetrain. Today’s vehicles produce substantially more horsepower, torque and towing capacity than their predecessors, yet the design of differential gears and bearings remains largely unchanged. Many differentials even use less gear lube and lower viscosities than before in an effort to reduce drag and increase fuel economy. In essence, less gear lube is responsible for providing more protection.

Fighting the Grind

Differential designs have inherent weaknesses. In a traditional automotive differential, the pinion gear concentrates intense pressure on the ring gear. As the gear teeth mesh, they slide against one another, separated only by a thin layer of lubricant. The repeated stress the lubricant film bears can shear gear lubes, causing permanent viscosity loss. Once sheared, the fluid film weakens, ruptures and allows metal-to-metal contact, eventually leading to gear and bearing failure. The situation is amplified by severe-service applications like towing.

Thermal Runaway

The extreme pressures and temperatures placed on gear lubricants can lead to a serious issue called thermal runaway. As temperatures in the differential climb, some gear lubes lose viscosity and load-carrying capacity. When extreme loads break the lubricant film, metal-to-metal contact occurs, increasing friction and heat. This increased friction and heat, in turn, results in further viscosity loss, which further increases friction and heat. As heat continues to spiral upward, viscosity continues to spiral downward. Thermal runaway is a vicious cycle that leads to irreparable equipment damage from extreme wear, and ultimately catastrophic gear and bearing failure.

AMSOIL SEVERE GEAR Synthetic Gear Lube

SEVERE GEAR 75W-90, 75W-110 and 75W-140 excels in protecting gears and bearings from the rigors of severe-service operation. By design, it resists breakdown from high heat, preventing acids and carbon/varnish formation. Its wax-free construction also improves cold-flow properties, improving fuel economy and cold-weather performance.

Also available are 190 and 250 weight versions!

• Superior film strength

• Controls thermal runaway

• Protects against rust and corrosion

• Helps reduce operating temperatures

• Maximum efficiency

• Long oil, seal and equipment life

• Flexible easy-pack for clean, fast installation

Introducing the Three Newest AMSOIL Products

Jamie Jarvi|

AMSOIL is well-known for its products that protect the internal parts of an engine. But you may not know about our products that protect the outside of your vehicles and equipment, too. Hot on the heels of the revolutionary new SEVERE GEAR easy-pack, we’re excited to announce three more products that will have the outside of your vehicles and equipment looking as pristine as the moving parts inside.

AMSOIL Mudslinger®

Sioux Falls ATV customers were asking about this before we had it! Now we do!

Mudslinger is a pretreatment specifically formulated to leave a non-stick surface that provides a protective layer of armor against the accumulation of mud, dirt and snow on ATVs, UTVs, snowmobiles and dirt bikes. This protective layer causes mud and dirt to release easier with low-pressure water, making cleaning faster after riding. UV rays can fade colored surfaces over time. AMSOIL Mudslinger resists the harmful effects of UV rays and helps equipment keep its original luster and shine with a pleasant cherry scent.

AMSOIL Engine Degreaser

You don’t need much to see results. Works without having to warm the engine up.

This professional-strength formula removes the toughest grease, dirt and grime from engine surfaces. Formulated with powerful degreasing solvents, it delivers a powerful stream that’s safe to use on all engine components and leaves no residue. Simply spray on and wash off with water.

AMSOIL Glass Cleaner

Oh man!! This glass cleaner works so well you may want to call your brother and alert him about it. Also let’s your wife know the $$ all these years spent on AMSOIL went to legit R&D.

Glass Cleaner provides a professional-strength formula that cuts through grease and grime quickly and effectively. Its ammonia-free formulation is safe on all glass including tinted windows. It remains in place where sprayed and will not drip or run, leaving no streaks or haze behind.
