The normal time to change your oil is three months or 5000 kilometres (3000 miles). This is under normal day to day use of your vehicle, extremely hot or extremely cold climates you may want to increase the intervals slightly.
If you pull a trailer more than once a week it is a good idea to also change your oil more frequently, oil is cheap compared to an engine related failure.
When Should I Check My Air Filter?
Air filters should be checked every oil change, check for deposits in the filter, some discoloring or dust is ok, you should never clean an air filter, in most cases they are disposable, there is an expensive variety which can be cleaned, if you are in doubt throw it out, again air filters are relatively inexpensive.

When Should I Change My Transmission Fluid?
Transmission fluid should be checked every oil change, automatic transmissions are checked by a dip stick usually mounted toward the rear of the engine and may be yellow or red to make locating it easier, this depends on the manufacturer.
An auto transmission should always be checked with the engine running and in PARK so great care MUST be taken when working around a running engine. Fluid should always maintain a bright red color and not smell burned in any way just a quick careful sniff of the fluid will tell you all you need to know.
Manual transmissions are a lot more difficult to check levels, this level is checked by removing a level check screw located on the left or right side of the transmission itself, just below the center of the housing, when this screw is removed a small stream of fluid should run out. The color of manual transmission fluid is much different than that of the automatic; this fluid may be dark or grey.
Auto and manual transmission fluid should be changed every three to five years to maintain good transmission health.
