Starting after storage
 

My 03 s has been stored under cover for 18 months. I plan to start it soon and wonder if anyone has advice on this. My thinking is to pull the plugs, add Marvel oil and rotate by hand. Change the oil/filter(before or after initial start up?). Also I added Seafoam to the fuel before parking it. Any advice would be appreciated.

Next time you should do fogging oil in all the cylinders before storage as well as adding stabil to the gas tank.
