the engine is the most important thing in the car, if you want to keep it run very good , i have few idea
1. change the oil every 1000 mile
2. use mobile or benz oil
3. don't exceed your speed in high way over 60 mil/ hour
4. if you have garage, if you come from long trip open the hood to let the engine cool down faster, that's why some times you will found the rubber part( like the wire of the spark plug it become stifness) if you don't open your hood specialy in summer time . the absorbant heat of the engine with the closed hood will be like the ( oven) !!!
