Precautions are better than getting screwed bro. Besides, I never have had a japenese car. I just bought it and the engine seems too much hot just after driving 7-8 km. Made the deal last week for this car, checked oil through gauge and it was perfect. Took delivery 2 days ago, checked oil in gauge and it was low. So, is it consuming the oil? I filled it up anyway. Will drive further and see if it still consumes the oil. If it does, I reckon ring pistons are screwed up and maybe a reason for over heat.
