hi
before i atempt to start the car i would like some advice on what should be checked/done before i do.
The car has been sitting for just over 5 years, and the gas tank has only been filled half way, and the oil hasnt been changed since.
I know the simple things such as changing the oil, new battery, spark plugs/leads, rad and oil filter but thats about it.
Now since ive had the car its never been started and have been told a full tank of gas should be done when leaving it for a long period of time, but has only had half a tank is this going to cause problems do i have to rip out the tank and clean pipes ect?
Also the oil hasnt been change in 5 years or so, so i can drop that stright out and pour new oil in?? or do i have to pour something call Marvel Mystery oil in each spark plug hole and crank it over without the leads?? then change the oil or check the condition of the pistons?
ALL HELP WOULD BE GREATFUL as i have never done anythin like this before

THANX
