Storing the Z for long periods

perfectnobody

just finished paying off my Z after 4 months... hoorah!!!...

lol

anyway, i only drive once or twice a month, (still less than 2k on the odo)

looking to get a car cover (any tips or recommendations on these 2, or any others out there)
The Grey Max Car Cover Size 3 to fit NISSAN (Datsun) 350Z 2009

https://store.coverking.com/ (prices range from 160 to 370) seems pricey

also, been hearing that letting fuel sit for more than 30 days is bad, does anyone use a fuel stabilizer? what has been your experience. i try to use up all the fuel when driving and leave it close to empty when done

is this also true for oil (read somewhere you should change your oil at 4k miles or 3-4 months, whichever comes first. being that i have had the car for 4 months, should i change the oil now with only 1800mile on the odo.

what other tips or advice do you guys have for keeping my car stored for long periods of time

reason is i am away most of the time and visit home once or twice a month. trust me, would love to drive this beast every single day

been looking through the forums and have found some good stuff, but would like to hear from you guys as well.

thanks in advance
