At the end of 2022, I'm planning on storing my 2005 Toyota Sienna with 100,000 miles. It's getting detailed and waxed along with a quality car cover that is going to be stored in my garage. I plan on taking out the battery and leaving the car on 4 jack stands. Now for the oil...since it's going to be stored for 2 years, shall I drain the oil and leave the engine empty being that motor oil breaks down from 6 months to a year? What about fuel? Shall I leave the tank empty or fill it up with fuel stabalizer?
Leave the fuel tank full with stabilizer and leave all the oils in too to keep things from Rusty the rest are doing all correctly
If it's getting stored for two years I'd put the battery back in once a month & let it run for a bit once it's up to operating temp to prevent any surface rust in the engine. Last thing you want is a cylinder getting light rust & possibly damaging the rings.
Also if its been a while since you've done the coolant, a flush would be a good idea.
In two years you'd be surprised what can happen internally if it's just sitting.
