well, i'm leaving for basic training on Tuesday, and I'm gonna be away from the car for a long time about 8-9 months. what should i do with the car, i'm not really worried about the tires since their already gone, and get new ones when i get back. i put fresh oil and filter in, new fuel filters did a diesel purge sprayed wd on lots of rubber parts, new return lines, fixed any leaks so no water gets in the car, cleaned the inside, now i hear mixed things to do with the fuel tank, leave it full or empty and additives to put in. also another big issue is i live in Massachusetts and it's gonna be out in the winter. i have no garage or anything, so possibly a car cover. also its an 84 300d. any suggestions would be helpful.
