I am getting my Delorean I just bought here a couple of days ago(this upcoming Monday to Tuesday to be specific) and needed some help on a few small things. 1. What type of motor oil should I use in the car(I plan on having the oil change when I get for safety purposes). 2.What fuses should I check for these minor problems: Radio inoperatable, door lights and interior lights sometimes work, the door locks (which seem to act funny), and the blower/AC fan(cuts in and out). 3. When I receive it this upcoming week I plan to undercoat the bottom. I checked NAPA and the best undercoating they have is water resistant, partially rubber compound that will last for at least five years.(The car has no frame rust and is a mid-year 81). Are their any special things I should know before I undercoat it ? 4. The tank sending unit(fuel gauage) only works half the time. The previous owner has just installed a new one within the past year from DMC Houston. Is their a short or maybe a loose connection? Joel #3121
