Yes. Using AMSOIL synthetic ATV/UTV lubricants has no effect on ATV/UTV warranties. A federal law called the Magnuson-Moss Act (1975) prevents original equipment manufacturers from putting conditions on warranties attached to any product or service identified by brand, trade or corporate name, unless the manufacturer provides that product or service free of charge. This means consumers have the freedom to use aftermarket products of their choice without fear of losing the original limited or implied warranty.
