What type of oil is used on the transmission of a yamaha virago 535? an how many quarts would you have to put in it?

To change your oil you will need 4 quarts of oil, a filter, and a new aluminum drain plug washer. You can reuse the old drain plug washer if it has not been squished out of shape. Your motorcycle comes from Yamaha usually with 20w-40 mineral base motorcycle oil. You can use any oil that is JASO MA certified motorcycle oil. 10w-40 for cold climate. 20w-50 for warm climate/touring. Car oils use different additives and may cause scoring in certain types of cam bearings. Do not use any oil that says " Energy Conserving " on the label . It will shorten the life of your wet clutch and transmission gears. If you choose Synthetic oils, they will help your bike run cooler and shift easier. Pour in three quarts of oil and add enough from the fourth quart to reach the high mark on the dip stick or inspection window. Make sure the motorcycle is upright or on the center stand when checking the level . You will probably need 3.1 to 3.4 quarts to hit the high mark. Run the motor for a minute or two to fill the oil filter compartment with oil. Now recheck the oil level and top up as needed.
