» The 3,000 Mile Oil Change Myth and Scam
Consumer Reports:
"Even in the severe driving conditions that a New York City taxi endures, we noted no benefit from changing the oil every 3,000 miles rather than every 6,000. If your driving falls into the “normal” service category, changing the oil every 7,500 miles (or at the automaker’s suggested intervals) should certainly provide adequate protection. (We recommend changing the oil filter with each oil change.)"
Below are examples of not "normal" driving.
-Driving less than 5 miles per trip, or in freezing temperatures, driving less than 10 miles per trip,
-Driving in extremely hot (over 90 degree) conditions,
-Used primarily as a delivery vehicle or taxi that is driven mostly in stop and go traffic and/or parked with the engine idling,
-Trailer towing, driving with a roof top carrier, or driving in mountainous conditions, or
-Driving on muddy, dusty, or de-iced roads.
