How long can I let my Yaris sit before risking damage?

The best way to store cars is to drive them. I drive my pick up truck 10 miles a week on Wednesday. If you can’t do that I agree with the others to put stabilizer in the gas tank and put a trickle charger on the battery.

Oil does not wear out synthetic or regular. It Hass to be changed because of contaminants no because of its molecular structure. My 2020 corolla is post to use synthetic oil and has a 10,000 mile oil change interval according to the manufacturer.

That’s pretty crazy in my opinion

Good advice. I agree, driving them is the best. It is not an option for me, other than back and forth in the driveway. The whole purpose of taking it off the road in winter is to keep road salt off the car.

The additive package - which provides a variety of protections - in the oil can wear out, or more appropriately, become depleted, and oil molecule chains can shear and result in viscosity loss. TBN, or Total Base Number, is a measure of remaining additives in the oil, though it can't be determined without doing an oil analysis. The oil in my car did not get changed this year before storage, as it was changed a few hundred kilometers ago. It's very clear and light honey-colored.

Yeah, even though modern oils are capable of extended drain intervals, I still stick to 8000 - 10000 km changes and this is a change for me as I used to go 5000 - 6000 between changes. It's hard for me not to change it more regularly as I have many jugs and bulk supplies of filters for all my cars.
