Getting ready to go on 3-month cruise. Based on past success in storing our 2006 IS250 and 2001 Ford Ranger for 4-months in 2018, we're planning on including our 2019 ES350 as follows:

1) Fill fuel tanks and add fuel stabilizer.
2) Add air to tires not to exceed tire max pressure.
3) Connect battery tenders (Deltran Battery Tender Junior).

Cars will be garaged.

Any comments or suggestions?

 

The 3 items on your list are all good things to do I'd add one more thing.

I'd try to add some protection against the possibility that mice or other rodents might find a way into the garage, try to make a home in the car, and build a nest, gnaw on wires, or do other damage to the car. I would place some sort of netted bag filled with moth ***** in the engine department. I'd also use cable ties to tie a few dryer fabric softener sheets at a few locations in the engine compartment, and I'd also use a netted bag filled with shavings from Irish Spring or Coast soap and put that in the engine compartment. All of those things will discourage mice from wanting to be in the engine compartment. You can also put one of more of those things into the cabin on the floor near the heat vents.

Even if you haven't had mice in the garage previously, they are very good at finding ways into garages, especially through small openings around the overhead door, and, with a car that is not driven for months, they can do lots of damage.

 

Other than what Les suggests, I think you've nailed it... I just put my Corvette away for the winter and did everything exactly as you posted... Have a great cruise...

 

Thanks for the tip on mice & rodents. Now this gives me a good excuse to replace the garage door bottom seals and to lay out some non-lethal mice traps.

Also read somewhere that, if garaged, you should leave the engine hoods up and the garage overhead light on to further discourage dark hiding places.

 

Any non-lethal mouse trap will turn lethal in 3 months.

 

One other thing you may want to do is to change the oil if it has significant miles on it. Oil dissolves acid as the miles build up and older oil is more acidic.
