The Wolverine 350 is an ATV (all-terrain vehicle) made by Yamaha. The intended use is as an off-road, recreational vehicle. The Wolverine 350 has an air-cooled, four-stroke, single overhead cam engine. As with any gas-powered engine, maintenance must be performed to keep the engine running as expected. Part of that maintenance are the oil changes. Oil changes should be performed every six months, 1,600 miles or 160 hours of operation, whichever comes first.
