I once often left my pick-up stored for a month. Then when I come back, I just put back the battery and start the engine. Andar naman parati.

One time I did not come back for more than two months. When I started the engine, it sounded terrible - like there was no oil in the engine. It sounded terrible for a few minutes. Akala ko nga nasira na ang engine ko. I noticed also that medyo mausok na.

But I now use the vehicle more regularly and it still works fine.
