my evo 8 been sitting in my garage for about 5 months.
never started it/let it idle the whole time.
whats the worst that could happen?
should i have drained the fluids?
any precautionary procedures when i run it?

 

Honestly I wouldn't worry about it. Make sure battery has juice and fire it up. My car sometimes is not driven for months at a clip anymore (Summer usually) and she always cranks right over flawlessly

 

You should be just fine, as long as all your fluids are full fire it up and let her warm up!

 

I am a little more cautious. I would disable crank sensor and clutch switch and crank it over until the oil light goes off while NOT pressing the clutch. Once the light goes off plug crank sensor back in and fire it up. Then you can enable the clutch switch. I wouldn't do a lot of high boost pulls until the old gas is run out or if it is low at least topped off with a full tank of fresh gas.

 

Just start it up change the oil then get fresh gas. i would try not to hit full boost till then.

 

My car is your typical "garage queen" - my car sat all winter with the occasional start up when I had to move it around the shop. A lot of people suggested getting a battery tender for mine since I have the smaller battery in my car. Mine was perfectly ok with no worries. I wouldn't be to worried about it!
