“Good Morning Ryan,

Yes, to replace the Polaris AGL Gearcase fluid in Polaris ATV/UTV/SxS transmissions, we recommend the Royal Purple Synchromax (part #01512) once strict OEM warranty compliance is no longer a serious concern.

OEM Or Aftermarket

Using OEM or aftermarket products is a question that has been raised in the automotive community for a time. I also can find it is one of the biggest debates on many forums. 

Always note that if your car is under warranty, you should stick with OEM products. Using aftermarket options can make your dealership void it. 

Even if your vehicle is out of warranty, the dealers would ask you to use OEM fluid. This may be a tactic by car manufacturers. However, OEM products are usually more expensive than alternatives on the market. Nowadays, oil manufactures design their products as good as factory fluid with lower prices. That’s why many people tried to find a good substitute for their vehicles.

using aftermarket product instead of OEM approved product when your vehicle is under warranty can make dealer void it.
You must be wise when choosing OEM or aftermarket products for your vehicles.

About Polaris AGL

What Is Polaris AGL Fluid?

The Polaris AGL is a superior quality lubricant designed to maintain ultimate performance for Rangers and off-road vehicles with RPMs. The manufacturer uses advanced technology to formulate AGL’s additive system to protect critical transmission components from regulating moisture.

They properly designed the AGL to offer your vehicles peak performance and control intense engine conditions in RZR riders and Rangers. Its unique viscosity is formulated to provide necessary protection and transmissions in ORVs.

At the same time, the viscosity maintains absolute heat resistance to protect the dynamic components under high temperatures.

Why Is Polaris AGL Pricey?

Polaris AGL Transmission Fluid

Polaris AGLs are engine precision that uses multiple critical components that you cannot find in standard transmissions. The AGL uses spiral cut, drive chains, and helical that require particular lubrication to enhance performance.

The work of the Polaris transmission fluid is to transmit power to the engine while absorbing excess shocks. The extreme pressure additive system of the AGL produces an oiling film to protect the gears from wear and extreme shock loads.

AGL’s viscosity is pretty light to provide excellent bearing and chain lubrication in all extreme conditions and climates. There is no alternative aftermarket transmission oil that can protect gearcases compared to the AGL.
