Since the end of September 2015 my 1991 Cadillac Deville has been sitting on the driveway untouched. I wanted to drive it again, but before I did I wanted to ask you, members of the forum, if there is anything I should do to the car prior to driving it?
The vehicle has been sitting there untouched for about 7 months and I’m concerned about the gas, potentially the oil. Just prior to it sitting there I had all of the fuel injectors replaced which cost a fortune, so I want to be sure to tackle this issue of bad gas in the best possible way.
A little aside, I know the Cadillac needs a new battery. I would also like to mention the last oil change it had was probably a year ago which I used full synthetic mobile one and I probably put a thousand miles on it since that last oil change. The Cadillac was in full working order prior to having it sit there for almost 7 months.
Any advice on what I should do is appreciated!
