AMSOIL Synthetic Chaincase & Gear Oil is specifically designed to maximize power transfer from the engine to the ground while reducing friction. It provides superior protection even when subjected to extreme pressure and high temperatures, with cold temperature flow protection for immediate protection and easy starts in colder weather. Additionally, it helps prevent rust, corrosion, oxidation and foam formation.

Optimizing Power and Endurance for ATV's and Snowmobiles

AMSOIL Synthetic Chaincase & Gear Oil is specifically designed to protect the vital components of ATV and snowmobile drive systems. It outperforms conventional oils by providing superior lubrication in extreme temperatures and high loads, protecting those components from wear and extending the life of your machine. With AMSOIL’s advanced synthetic technology, your ATV and snowmobile will have improved power transfer, smoother shifting, reduced noise, longer life and better overall performance.

The Purpose and Benefits of a Chaincase Explained

Regular oil changes are necessary to keep the chaincase of a snowmobile in proper working order. The chaincase contains the necessary components for a chain-drive system and works similarly to motorcycle and ATV/UTV systems. However, it's also sealed off from outside elements like moisture or corrosion that can cause wear and tear. AMSOIL Synthetic Chaincase & Gear Oil is specifically formulated for extreme cold, delivering reliable protection and performance even in some of the harshest winter conditions.

Why You Need to Change Your Chaincase Oil Regularly

AMSOIL Synthetic Chaincase & Gear Oil is specifically designed to handle the extreme cold temperatures and friction common in snowmobiles. When used as directed, this oil helps extend chain life and prevent damage from metal shavings, moisture, and pressure heat contamination. It should be changed annually or every 2000 miles (3200 km) and should be filled to spill when refilling the chaincase - typically 8-11 ounces (237-325 mL).

Meeting Unique Requirements

Modern snowmobiles and ATVs have certain distinctive requirements when it comes to chaincase & gear oils. While many people try to substitute cheaper alternatives for these lubricants, this is not advisable. Automotive transmission fluid does not have the extreme-pressure additives necessary to protect the gears and chains, and automotive gear lube is too thick for proper chain and gear lubrication in powersports applications, leading to increased wear and decreased efficiency. AMSOIL Synthetic Chaincase & Gear Oil is designed with SAE 75W specifically to ensure maximum protection for snowmobiles and ATVs.

A Closer Look at the AMSOIL Advantage

AMSOIL Synthetic Chaincase & Gear Oil (TCC) is designed for maximum protection and performance in snowmobiles, ATVs, and other similar equipment. Its high-performance synthetic formulation helps resist shear and chemical breakdown better than conventional oils, providing superior wear protection that extends chain and gear life. This oil also repels water to inhibit rust and oxidation, while its low pour point ensures efficient low temperature starting. Engineered with extreme-pressure additives, AMSOIL Synthetic Chaincase & Gear Oil delivers maximum power through the cold winter months, all while costing less than most OEM recommended chaincase oils.
