I am wondering if I should replace the oil before starting it up? Also what other tune up parts or steps I should look at for first time startup?

Car hasn't run in 4-5 months, just sitting with the battery disconnected.

 

Don't count on the battery being up to snuff. JMHO

 

battery should start it up, i think. Mine sat for a similar time, until i recently started it up. It turned over just as if it had been running the day before, although i did not disconnect it.

 

That is why god created the bump start Should I roll the car out, change the oil and then let it run for lets say 30 minutes...? I've never stored my car before.

 

I'd say roll it out, change the oil, start it up, let it idle til the rpms settle down and go for a ride for 30min, keeping it between 1500-2000. Just make sure that you get instant oil pressure upon start up. JMHO

 

If the car has been in storage for that amount of time, it would be a good idea to change the oil.

 

Alright thanks guys
