Evaporative emission systems perform a few simple functions.  Venting the fuel tank when needed and disposing of the fumes are the primary purposes.  They use an incredible amount of complexity to address these tasks, largely due to Government regulation.  This leads to many check engine lights, perhaps more  than any other system on the vehicle.



Oil Change Intervals

Oil change intervals are one of the most disputed topics in the automotive field.  Recommendations from 3,000 up to 20,000 miles are common.  Mileage recommendations, without regard for long-term results, are irresponsible.  Driving conditions and not mileage, determine oil change needs.

What Are The Symptoms of a Bad Fuel Filter, In-line and In-tank

Fuel filters clean fuel and help protect fuel injectors. Good maintenance has always dictated replacing fuel filters at regular intervals. Today they are disappearing from maintenance schedules and the under side of vehicles.

What is Torque Converter Shudder

Driving about 45 MPH there is a sudden shudder in the vehicle. It almost feels like running over a rough spot in the road or a cattle guard. As quick as it appeared, it is gone, until the next time it occurs.



Engine Thermostats, Fuel Mileage and Over Heating

Most folks realize an engine thermostat can cause a vehicle to overheat. Did you know thermostats are also one of the leading causes of poor fuel milage?



Replacing Power Steering Fluid The Easy Way

Virtually all modern vehicles have power steering and the majority are still hydraulic. These systems are reliable and easy to keep that way with a few simple tips.
