Fuel Saving Tips
If you have a way to gauge your temperature then adding a grill block is a good way to help the engine warm up faster and once your car is upto operating temperature you can use your blower (set to hot) to cool the engine (you may have to experiment first by turning your hot blower on to see if it does lower your engine coolant temps). also, by doing this all the waste heat is going into the car to keep you warm and not heating the outside air.
