Tune ups & maintenance is more critical on a vehicle today than in past times because of tolerances in the engine components. Cars and trucks these days have better materials and performance, but the closer tolerances mean that small problems become big problems much faster.
Most people see the advertisements for vehicles with 100,000 mile maintenance-free programs and think they can go that long without any maintenance. But there are a couple of problems with that. First, those ads are designed to make vehicles look like they have a lower cost of ownership. Some necessary services are not included in that 100,000 mile promise. Also, those mileages are under optimum driving conditions, which nearly no one in Anchorage has. Anchorage has temperature extremes from below zero in the winter to well above 100 degrees in the summer. Also, many drivers deal with stop-and-start driving, which is not “optimum” driving conditions.
