Synthetic Gear Lubes

For Superior Lubrication in Automotive,
Marine and Industrial Applications

AMSOIL Synthetic Gear Lubes are extreme pressure lubricants engineered specifically to meet the high temperature/high load demands of today’s geared equipment. AMSOIL Synthetic Gear Lubes, unlike conventional lubricants, don’t break down in extreme heat and form damaging deposits, varnish and sludge. AMSOIL Synthetic Gear Lubes maintain their protective capability even in thermally stressed conditions, preventing the ridging, rippling and spalling caused by surface distress. In addition, the superior lubricity of AMSOIL Synthetic Gear Lubes improves fuel economy and provides limited slip capability.

SEVERE GEAR Synthetic EP Gear Lubes -- 75W-90, 75W-110, and 75W-140:

SEVERE GEAR Synthetic EP Gear Lube is specifically engineered for high demand applications, including trailer towing, heavy hauling, 4X4 off road driving, commercial use, and racing. Superior lube "film strength" combined with extra additives protects gears and bearings from scoring and wear. Resist high heat and possess excellent cold flow properties. Outperforms all conventional gear oils. Recommended for all types of vehicles such as turbo diesel pick-ups, SUVs, autos, trucks, heavy equipment and motor homes. Compatible with most limited-slip differentials.

Synthetic Off-Road and Drag Racing Gear Lubricant

Synthetic Off-Road and Drag Racing Gear Lubricant -- SAE190 and SAE250:

SEVERE GEAR Synthetic Off-Road and Drag Racing Gear Lubricants are premium grade, extreme pressure gear lubes engineered specifically for the demands of severe racing conditions. They are formulated with shear stable, heavy synthetic base oils for "high film strength" and extra heavy treatments of additives. Their synthetic formulations provide improved flow over conventional oils, reducing viscous drag and power loss. Severe Gear SAE 190 and SAE 250 Gear Lubes provide a barrier cushion between metal surfaces that absorbs impact. AMSOIL proprietary extreme pressure additives form an iron-sulfide barrier coating on gear surfaces for the ultimate line of defense against wear, pitting and scoring.

Long Life Synthetic Gear Lubes -- 75W-90 and 80W-140:

Long Life Synthetic Gear Lube is specifically engineered for extended drain intervals up to 500,000 miles as set by equipment manufacturers for over-the-road trucks and heavy equipment. Prevents wear and improves equipment life. Excellent "All Season" summer and winter performance. Outperforms all conventional gear oils. Also excellent for passenger cars and trucks. Compatible with most limited-slip differentials.

AMSOIL Synthetic 80W-90 Gear Lube

Synthetic 80W-90 Gear Lube:

Synthetic 80W-90 Gear Lube is a high quality replacement for applications specifying SAE 80W-90 conventional gear lube. Synthetic construction provides improved cold flow properties, high viscosity index and heat resistance. Contains an over treat of high quality additives, exceeding the minimum standards. Provides excellent wear protection and long equipment life.

Synthetic Marine 80W-90 Lower Unit Gear Lube:

Marine Lower-Unit Gear Lube provides true marine gear performance, resists foam and retains extreme pressure qualities even when subjected to 10 percent water contamination. For use in outboard lower units, stern drives, V-drives, bow and tunnel thrusters and marine transmissions requiring a SAE 75W-90 or 80W-90 meeting either GL-4 or GL-5 performance standards.

AMSOIL Synthetic Manual Transmission and Transaxle Gear Lube

Synthetic Manual Transmission and Transaxle Gear Lube:

Synthetic Manual Transmission and Transaxle 75W-90 Gear Lube Designed to meet the special requirements of certain manual transmissions and transaxles. Provides improved internal component protection. Formulated with extreme pressure additives and advanced synchromesh qualities that provide smooth shifts while protecting gears, bearings and seals. Non-corrosive to yellow metals. Recommended for manual transmissions and transaxles that require 75W-85, 75W-90 or 80W-90 viscosities.

Synthetic Synchromesh Transmission Fluid:

Synthetic Synchromesh Transmission Fluid is specifically designed for manual transmissions and transaxles with synchromesh systems that require light viscosity, non-extreme pressure fortified oil. Formulated with advanced additive technology to provide proper friction characteristics for smooth shifting without grinding or bump shifting while providing the ultimate in gear and bearing protection. Outperforms motor oils in manual transmissions and provides excellent performance in extreme temperatures from -40 deg. F to 300 deg. F. Possesses outstanding anti-wear and anti-foam properties and is non-corrosive to yellow metals.

AMSOIL Chaincase Lubricant

Synthetic Chaincase & Gear Oil:

AMSOIL Synthetic Chaincase & Gear Oil provides superior protection and performance for enclosed chains and gears found in snowmobiles, ATVs and general equipment. Formulated with extreme-pressure additives, it helps extend chain and gear life through increased wear protection. AMSOIL Synthetic Chaincase & Gear Oil repels water, while also inhibiting rust, oxidation and foam. Its low pour point ensures superior low-temperature starting, reducing drag to deliver maximum power.

Slip-Lock Differential Additive:

Slip Lock Differential Additive eliminates gear-housing chatter in cars, trucks and SUVs equipped with limited-slip, posi-traction and locking differentials. Reduces banging and clunking associated with automatic locking differentials. Formulated for use with both synthetic and petroleum gear lubricants and safely replaces manufacturer-recommended friction modifiers. One bottle treats differential capacities of two to four quarts.
