My 2004 I35 has sat in the driveway for the past 6 months. The gas is 6 months old without any additive and the oil was changed before I parked it for the winter, in New England.
I want to start it up and drive it during the summer and fall.
What are the necessary and recommended steps to take, so I don't damage the vehicle?
All answers are appreciated
Thx

6 months shouldn't be a big concern, just check the fluids and get back to motoring.

I'd agree with Chump, except for the following:

From now on, put some StaBil in the tank.
Before starting it, pull the coil wire and crank it over several times to get some oil circulating before startup.

Otherwise, you should be good to go!

Sounds like good advice. I was on the road for several days and just got home to see all the advice. I followed the advice given and was successful.
I let the car warm up for 5 minutes then took it for a 20 minute drive around town. The right front brake was dragging a little bit but with gentle persuasion and cleaning it releases itself. The idiot lights give no indication of problems and under the hood there are no leaks noted.
Thanks for responding it was much appreciated.

Welcome aboard!

Sometimes I wonder about all the cars at rental facilities and dealerships that just sit for months, waiting to be given away...for free. They just want to be driven.

I rented a Nissan Pathfinder recently, a 2019. There was cobwebs, and the brakes felt wobbly the first couple hundred miles. Probably been sitting for weeks or months. Ideally I would have complained, but it was overall such a yacht of a ride lol. Definitely drove like an Infiniti lol.
