Product Data Sheet For AMSOIL 100% Synthetic ATV/UTV Transmission & Differential Fluid.

SEVERE-SERVICE WEAR PROTECTION

• Synthetic technology delivers reserve protection for machines burdened with the added weight and stress of a payload, a cab, a winch, plow and other accessories.
• Protects heavily loaded, high-torque gears and bearings against wear in the most severe operating conditions.

SUPERIOR EXTREME-TEMPERATURE PERFORMANCE

• Cools critical components and resists the effects of extreme heat to deliver reliable protection in severe service.
• Synthetic technology helps it remain fluid in cold weather for fast, reliable protection.

AMSOIL 100% Synthetic ATV/UTV Transmission & Differential Fluid – Heavy-Duty Driveline Protection

AMSOIL 100% Synthetic ATV/UTV Transmission & Differential Fluid is built for the hardest-working parts of your machine. Your transmission and differentials take constant shock loads from rocks, ruts, trailers, plows and heavy accessories. This fluid is custom-engineered to protect those parts under serious stress while keeping everything running smooth and quiet.

It uses a shear-stable synthetic formulation that stands up to high torque and brutal conditions. If you work, tow or play hard with your ATV or UTV, this is the kind of driveline protection you want.

What This Fluid Is Designed To Do

Custom-Engineered For ATV/UTV Drivelines

This is not a generic gear oil. It is designed specifically for:

• ATV and UTV transmissions
• Front and rear differentials
• High-torque driveline components where specified

It is a great match for machines used in:

• Hauling and towing
• Plowing snow and dirt
• Trail riding in rocks, mud and sand
• Worksite and farm use

When your machine is loaded down with a cab, winch, plow, passengers and gear, this fluid helps your driveline survive.

Severe-Service Wear Protection

Strong Film Strength For High-Torque Gears

Inside the transmission and differentials, gears and bearings are hammered by high torque. This synthetic fluid forms a strong, stable oil film that stays between metal surfaces even under shock loads.

It helps protect:

• Ring and pinion gears
• Planetary sets
• Differential gears
• Transmission gears and bearings

That means less pitting, scuffing and wear, even when you push your machine hard.

Shear-Stable Formula

Mechanical shear can thin out weaker fluids, leaving gears exposed. This fluid is shear-stable, so it keeps its designed viscosity longer. That helps maintain:

• Correct film thickness
• Consistent protection across the service interval
• Reliable operation in modified or heavily loaded machines

Superior Extreme-Temperature Performance

Handles High Heat In Severe Use

Towing, plowing and long hill climbs generate serious heat inside the housings. This fluid is built to:

• Resist thermal breakdown
• Reduce the risk of varnish and sludge
• Help keep components cooler under load

You get dependable protection when you need it most, like when pulling a heavy trailer or pushing a big snow blade.

Remains Fluid In Cold Weather

Cold weather can make some gear oils thick and sluggish. This synthetic formula stays more fluid at low temperatures, which:

• Helps lubricant reach components faster at startup
• Reduces drag and energy loss in the driveline
• Lets you use your machine year-round with confidence

Protection Against Corrosion, Foaming And Noise

Fights Rust And Corrosion

ATVs and UTVs often see water, mud, snow and high humidity. Moisture can creep into housings and attack internal parts. This fluid includes strong anti-corrosion additives that help:

• Protect gear teeth and bearings
• Reduce rust and staining on internal surfaces
• Support long-term reliability in wet or humid climates

Resists Foaming For Smooth Operation

High-speed gears can churn the fluid and pull in air, creating foam. Foamy fluid does not lubricate well and can cause noise and inconsistent operation. This formulation:

• Resists aeration and foaming
• Helps maintain a solid oil film
• Reduces gear whine and chatter

The result is a smoother, quieter driveline with more predictable behavior.

Ideal For Hauling, Plowing And Tough Terrain

Built For Work Machines

If you use your ATV or UTV like a compact work truck, this fluid is a smart choice. It shines in machines that:

• Pull firewood, equipment, trailers or farm implements
• Push snow or dirt with front or rear plows
• Run with added weight from cabs, roofs, racks and skid plates

These conditions greatly increase stress on gears and bearings. This fluid is designed to give reserve protection in exactly those situations.

Perfect For Aggressive Trail And Utility Riders

Even if you are not working the machine, hard play can be just as brutal. Fast trail riding, hill climbs, dunes, mud holes and rock gardens all hit the driveline hard. This fluid helps:

• Protect under sudden shock loads
• Control heat buildup from long, hard runs
• Keep differentials and transmissions alive in the roughest sections

Machines used in snow and extreme winter conditions often benefit from AMSOIL 100% Synthetic Chaincase & Gear Oil in any chaincase or gear housings. It is made to:

• Protect chains and sprockets from wear
• Fight rust and corrosion in wet, salty environments
• Maintain flow at low temperatures

Practical Use Tips

Confirm Specs In Your Owner’s Manual

Before filling, always check:

• The correct fluid type for each housing
• Recommended viscosity or category
• Any special notes about front, center and rear units

Use this fluid only in locations where a product of this type is specified.

Follow Service Intervals For Your Use

For casual riding, follow the standard service interval listed in your manual. If you:

• Tow or plow frequently
• Ride in deep mud or water
• Run added accessories and weight

you may want to shorten the service interval for extra insurance. Severe-use conditions always justify more frequent inspection and fluid changes.

Pay Attention To Fill Levels And Venting

When changing this fluid:

• Clean around plugs before removal
• Use the correct fill and level check points
• Ensure vents and breathers are not plugged

Proper fill and ventilation help the fluid do its job and reduce the chance of leaks or aeration.
