I moved to Brazil in January, 2004, leaving the Lude semi-stationary in the parking lot of a condo I own in Houston. I put in some fuel stabilizer (Propanol) and the car was started and driven about every three weeks for about a mile. The battery went dead after a year, but when I returned on vacation, the car ran great, with no indication of the crud that sometimes forms in the fuel system.

Does anyone have any experience with long-term storage of a Prelude? What do you recommend?

The car had Mobil 1 oil, Premium gas, and a fuel stabilizer, and was stored for 15 months with no problems upon driving other than the dead battery.

 

Remove battery and all fluids (oil, coolant.) If it gonna be a while then drain the gas tank or run it down to empty.
