Oil Change in Tucson, AZ

Owner's manuals usually carry two oil change intervals, and the shorter one is for severe service. Most drivers skip that page because they assume it describes racing or heavy towing. Read the list, though, and one condition on it describes a good share of the pickups around Tucson: driving in dusty conditions or on unpaved roads.

Dust matters to oil for a simple reason. Some of it gets past the air filter, especially when the filter is loaded or the seals around it are imperfect. Once inside, it ends up suspended in the oil, and fine dust in oil is an abrasive circulating through every bearing and around every piston ring in the engine. Fresh oil and a fresh filter take that dust out of circulation. Oil left in too long keeps grinding with it.

The oil change and the air filter are two halves of the same protection. A clogged air filter starves the engine of air, and a damaged or poorly seated one lets dust straight in. On a vehicle that spends time on dirt roads, have the air filter looked at every oil change rather than at the interval printed for normal use.

If the filter is caked with dust long before it is due, that tells you the vehicle is living on the severe schedule whatever the sticker says.

• Regular driving on dirt or gravel roads, or on job sites: follow the severe interval in your manual.
• Mostly paved driving with the occasional dirt road: the normal interval is reasonable, with the air filter checked more often.
• Not sure: choose the shorter interval. It costs little and protects the engine either way.

Anything due on the manufacturer's list can go on scheduled maintenance, and a leak spotted under the vehicle is worth an engine repair check, both here. The national oil change page covers what the service includes.

Phoenix and Yuma also change oil in Arizona.
