Review on 🚗 Autool X60 Car OBD2 Multi-function Speedometer & Diagnostic Tool: Over-speed Alarm, Water/Oil Temperature, Battery Voltage, Trouble Code Read/Clear – Ideal for 12V OBDII Auto SUV Pickup Trucks by Rafael Gomez

It reads some sensor data on my truck. But the engine temperature is 20 degrees Fahrenheit lower than the engine temperature gauge on the dash. No oil pressure, but oil temperature. The oil temp seems to read a much higher temperature than the IR thermometer. The speedometer is within reasonable limits of the GPS readings. But the odometer function is not correct. A GPS-based 32-mile trip is within +0.2 miles on the truck's own odometer, and the multi-function display reads 58.7 miles. Voltage readings are within fairly accurate readings based on a true RMS volt/ohmmeter (Fluke brand). I'm still working on this as it has a voltmeter reading and is within reasonable limits of accuracy. I already know that the engine coolant reading is 20*F colder than the actual reading. So when the truck's engine coolant temp gauge goes off again, I know my truck's engine temp is not overheating like the dashboard says it is. I don't know what the "thickness" and "mileage" ratings mean. . In general everything is fine.
