I just bought Ford Explorer Sport Trac last month but unfortunately, the owner lost the manual so I am not sure how to properly 'handle' my new trac. Below are my questions hoping that those with Ford Trac can enlighten me.

1. Is it OK to fill the radiator with water or I should use a mixture of water and coolant?
2. How full should the water resevoir be?
3. What brand of engine oil should I use if I have it changed?
4. I was advised to use gasoline with 95 RON. Can't I use 93 RON?
5. Would you know where I can buy a new set of manual for my trac?

Appreciate it. I hope you can help! Thanks.
