How to change your oil to AMSOIL

Step 2

Unscrew the drain bolt and drain the oil into your oil pan. as the oil drains, multi-task and change the oil filter.


Step 3

Remove the oil filter. You'll need a wrench to remove the oil filter cover or cap. Now, clean around the oil filter cover and inside the compartment where the filter goes.

Replace the old filter with a new filter, make sure to put some fresh oil around the rubber lip or seal before placing it inside.

Once the new filter is in place, put the filter cap back on and tighten.

Step 4

By now whatever oil is going to drain has drained. Clean off the drain bolt and screw back in. Add your AMSOIL Synthetic Oil and enjoy a smooth ride.
