Why Should I Use Polaris Engineered Snow Engine Oils vs. Different brands could be incompatible and could cause fuel injection system blockage, sludge formation, filter blockage and reduced cold weather flow rates. Never mix another brand of engine oil with Polaris oil. Note that if switching from VES to VES Extreme or from VES Extreme to VES, the two oils can mix. VES Extreme is the best product for high-performance applications such as turbo-charged engines, racing applications and other high-load or high RPM use. VES Extreme has the latest technology of Ester and PAO synthetic base stocks and high-performance additives that provide the highest film strength that reduces wear and provides the ultimate protection even under the highest demands. VES Extreme has enhanced lubricity and detergency for maximum engine wear protection. It offers superior flow in the extreme cold (-60 degrees Fahrenheit) and is formulated for easy starting in harsh conditions. VES Extreme features an advanced ester base for ultimate performance. It's formulated for easy starting in the extreme cold and provides enhanced valve cleanliness, low smoke and excellent lubricity.

VES and VES Extreme also contain our highest levels of engine wear protection additives, with a boosted detergency system to keep pistons, cylinders, rings and exhaust valves free of carbon and soot. VES and VES Extreme both use custom-engineered, full-synthetic base oils and offer our highest levels of protection in high heat, high RPM and heavy load use. What Are the Benefits of Using VES or VES Extreme? The heavier viscosity protects older engines and mixes easily with fuel, so it can be used for both pre-mix and oil-injected machines. Vintage 2-Stroke Snowmobile Oil is designed to specifically to meet the needs of older snowmobiles, including air- and liquid-cooled non-exhaust valve engines. Polaris Blue is a high quality semi-synthetic blend, specifically designed to work in fan-cooled non-VES snow engines (VES = Variable Exhaust System), like the 550 snowmobiles. and 850 engines should use VES and VES Extreme. VES and VES Extreme offer our highest levels of engine detergency and wear protection for Polaris snowmobile engines. Full Synthetic VES and VES Extreme are designed to work across all engine platforms, from entry level fan-cooled to our high performance, variable exhaust engines. Polaris Engineered Lubricants has four different types of snowmobile engine oils.
