Grzegorz Kilon arrived 35 minutes late. When he arrived, he did not have the filter. He came back 10:35 AM from the supposedly 9 AM appointment. Would have avoided the delay if he had it in the beginning. Also, PENZOIL was indicated that was used in receipt. He used an O'Reilly brand oil.

Godwin did a great job changing the oil in my car. First, he called me and arrived early for the appointment which I really appreciated. Then he answered my questions about the car that were not even related to the oil change. He has a good attitude and you can tell he know what he is doing. I absolutely liked the way he did the job and will certainly use his services again.

All about Oxygen Sensor Replacement

With each new model year, manufacturers are adding more oxygen sensors to better manage engine operation. Some high performance engines have an oxygen sensor for each cylinder as well as one for the rear of each catalytic convertor. The sensors are located either underneath the hood or underneath the car. The oxygen sensors are connected (screwed) to the exhaust pipe, either in front or back of the catalytic converter. The front (upstream) sensors measure the amount of oxygen in the exhaust system. The purpose of the front oxygen sensor(s) is to measure how rich or lean the gases are as the gases exit the combustion chamber. Depending upon whether the exhaust gas is lean (high in oxygen content) or rich (low in oxygen content), the amount of fuel entering the engine is adjusted by the engine management computer to try and maintain an ideal mixture that produces the lowest emissions output from the catalytic convertor. Rear (downstream) sensors are located behind the catalytic converter. The purpose of the rear oxygen sensor(s) is to monitor the oxygen content of the exhaust gases leaving the catalytic convertor. If one or more of the oxygen sensors are faulty, your car may not pass the emissions test. If you drive your car with a faulty oxygen sensor, you may get poor gas mileage and it can damage the catalytic converter.
